Chapter 245 Investing in the Old District Diesel Engine Factory
"Mr. Qin, what does Hikoda Shizuo's son have to do with Karl from MAN?" The matter has been finalized. Hikoda Shizuo racked his brains, thinking about how to complete the technical transformation of the factory under the premise of five million. Lin Bin curiously asked Ask Qin Tao secretly.
"His son studied in Germany and went to MAN during his internship. As a result, he and Carl became masters and apprentices." Qin Tao said: "It is absolutely a shame for the son of a machine-building genius to become a master of others! "
No wonder Hikoda Jushio agreed so readily. On the one hand, he had shown his trump card. Anyway, it was just the money, so let’s figure it out! If it doesn't work, replace him. On the other hand, it's also because Qin Tao caught Hikoda Shizuo's weakness and hit the vital point directly.
Five million US dollars is the price that their Bincheng Diesel Engine Factory can accept. They can spend this money to upgrade and grit their teeth. At this time, Lin Bin is very looking forward to the prospects of their factory after the upgrade.
"Mr. Qin, thank you for your help." Lin Bin looked at Qin Tao and said seriously: "After research by our factory committee, we have decided to hire you as the honorary consultant of our factory. I hope you can accept it."
Honorary Advisor?
Qin Tao glanced at Lin Bin curiously, what do you want to do?
"Please don't get me wrong. We won't put any burden on you. You don't have to stay here all year round. As long as you come to Bincheng occasionally, you can come to visit us." Lin Bin told Qin Tao: "We know. The salary of an honorary consultant is not enough to break your teeth. This is just a little bit of our thoughts. I heard that you have been looking for a suitable diesel engine factory. Our factory is willing to join forces with Mingzhou Shipbuilding Industry Group. "
Qin Tao smiled helplessly: "You want to provide supporting equipment for our factory. If there is an opportunity in the future, we will cooperate. What is the title of consultant..."
"Mr. Qin, please accept it."
Marine diesel engines can be divided into two-stroke and four-stroke according to the working principle. According to the speed of rotation, they can be divided into low, medium and high.
However, there are also disadvantages. This kind of diesel engine is very large and has a high volume-to-power ratio. Therefore, it is not suitable in places where land is at a premium, such as warships.
Everyone is shocked.
However, domestic diesel engines must always be developed, domestic products must be self-reliant, and the freighters produced in the future must be slowly equipped with a domestic heart.
"Yes, we plan to build a new generation of frigates for the Navy with an expanded displacement in order to install our most advanced domestic vertical air defense missile system."
Low-speed diesel engines can turn over a hundred or even dozens of revolutions per minute. There are also slightly higher four-stroke models that can turn to three or four hundred revolutions.
"Look at how many color TVs, motorcycles, refrigerators, washing machines, and even automobile production lines have been introduced in our country over the past few years. Each factory has taken the country's money and borrowed money from banks to compete with each other. It depends on which imported production line is better. However, after the introduction, quite a number of production lines cannot operate, cannot produce, and cannot create value. This is simply..."
But after the technical transformation of Bincheng Diesel Engine Plant, their production capacity can be rapidly increased, not only for Bincheng Shipyard, but also for other shipyards. Therefore, Lin Bin hired Qin Tao as a technical consultant. I also want to take advantage of it.
"Waste." Qin Tao gave an accurate word.
After the country opened its doors, China introduced many advanced technologies from the West. Some of them began to bear fruit domestically, while others were left idle.
In the automotive industry, the imported Santana is a model of success. FAW spent huge sums of money to introduce an engine production line from abroad, but ended up throwing it away.
Moreover, although it is called a diesel engine, it can not only burn light diesel, but some can even burn heavy oil, which is quite economical, and has become the first choice for many international ocean freighters.
"President Qin, I heard that the Navy has started to discuss the plan of a frigate with a displacement of 4,000 tons. It was your suggestion." Lin Bin suddenly changed the subject.
When Lin Bin called the diesel engine factory in the old district, Wu Shengli was doing research here.
"Okay." Qin Tao agreed. In this way, Qin Tao finally stepped into the circle of marine diesel engines. After entering the circle, it would be easier to find an opportunity to get a certain diesel engine factory under his control.
There are many marine diesel engine factories in the country, each with its own characteristics. For example, the one in Bincheng manufactures low-speed diesel engines, while theirs here manufactures medium- and high-speed diesel engines.
"Thank you, Mr. Qin! Without you, I'm afraid our factory's technical transformation would not be able to proceed." Lin Bin sighed with emotion: "Complete our transformation with the minimum cost, seek truth from facts, and follow our own path. This is what we The most correct choice!”
This project cannot be hidden. When Wu Shengli started to demonstrate it with the Navy, the news came out.
"Mr. Qin, you can always create miracles. Since you are prepared in advance, I won't say more." Lin Bin said: "The director of the diesel engine factory in the old district and I were classmates before, and he was also very fond of it." I look forward to your visit and investigation at their diesel engine factory and discussing countermeasures together.”
"That's right, it's a waste!" Lin Bin sighed with emotion.
Because the speed is extremely low, there is no need for a reduction gear, and the propeller can be driven directly, eliminating the need for a reducer. Some can even reverse, eliminating the need for reverse gears. And because of the slow speed, its lifespan is very long. Tall, just like a turtle.
At this time, Lin Bin was very happy to hear Qin Tao say this.
The destroyer under construction only weighs more than 4,000 tons!
Over the years, everyone has been very clear that if we take too big a step, we will easily get hurt. This step is really not a small one.
As for the missile boats that have been mass-produced now, they use MTU's high-speed diesel engines, which are small in size and powerful, and can run more than two thousand revolutions per minute. (This is the case with diesel engines. If you want to be like a gasoline engine, it is impossible to turn it on at 10,000 rpm. There are also high-speed diesel engines that can reach 3,000 or 4,000 rpm, which is already very impressive. The classification of this speed is also roughly It’s not that East China Heroes is unprofessional, it’s because they have different opinions.)
Although Mingzhou Shipyard now also has large ocean-going cargo ships, all of them use imported main engines without exception. On the one hand, it is the requirements of customers, and on the other hand, domestic diesel engines are not enough.
"Then let's use the facts to shut them up." Qin Tao said.
In terms of aero engines, the domestically imported Spey engine was such an important project at the time, but what about now?
Many things imported at high prices have been wasted. Their Bincheng Diesel Engine Factory must not follow such an old path. They must follow a path that suits them! We must also set an example for other factories.
"I don't know anything else, but your plan to combine two diesel engines involves a lot of technical risks. Those who oppose you all think about it from this perspective." Lin Bin said.
"It's just that your factory produces low-speed diesel engines and cannot be used on warships. You can try it on cargo ships if you have the opportunity in the future. If the customer decides to accept our domestic main engine, we will help sell it." Qin Tao promised.
If it weren't for Qin Tao's involvement, now the only option would be to replace the Hongqi 61 with the Hongqi 7 and install it on the frigate to form the 053H3 frigate. As a result, Qin Tao has taken a big step.
However, the problem of using two diesel engines to drive one propeller and merging vehicles is really before our eyes.
However, this technical problem has long been taken into consideration by Mingzhou's technical staff.
Wu Shengli didn't tell Qin Tao about these things. On the one hand, it was still early and the horoscope hadn't been revealed yet. On the other hand, Wu Shengli might have wanted to remain silent for the sake of fairness.
Moreover, as the country gradually moves closer to a market economy, there will be fewer and fewer projects that rely entirely on state power for investment and introduction. Most of them need to be carried out independently by enterprises.
Qin Tao helped them a lot, and of course they had to provide Qin Tao with some information.
After all, the most advanced 053H2 frigate currently under construction in China has a displacement of only about 2,000 tons. Now, it is actually a frigate of 4,000 tons?
"Leader Wu, our factory was founded in 1955. It was one of the 156 key projects during the First Five-Year Plan period. It is now one of the 665 key enterprises in the domestic machinery industry." Factory Director Wang Tianmin introduced Wu Shengli with excitement. Said: "At present, our factory is already a professional manufacturer of medium, high-speed and high-power diesel engines for domestic marine use and a complete factory of diesel generator sets."
The new frigate planned by Qin Tao uses four 16PA6V diesel engines from the old factory. These are medium-speed diesel engines. They need to be long-lasting, powerful and compact in size. The speed of this medium-speed diesel engine ranges from 600 to more than 1,000 rpm.
Although it is called an old district factory, in fact, they are not in the provincial capital, but in Xingping City, fifty kilometers away from the provincial capital.
The diesel engine factory in the old district is still waiting! After all, the plan proposed by Qin Tao requires four diesel engines for each warship. Doubling the number means that the orders from their factory will double. Of course, they are full of expectations. Moreover, the previous frigates used 18E390A diesel engines, which were not produced by their factory. Now choosing their diesel engines means that big business is coming.
"I won't go to the old district diesel engine factory. You and their factory director are classmates, so please send him a message and ask him to send us the relevant data of the diesel engine, and we will solve the problem of merging cars."
"Okay, that's no problem. I'll contact you right away."
Wu Shengli was very enthusiastic about the project proposed by Qin Tao. This was definitely not because Qin Tao was his son-in-law, but because Qin Tao proposed a low-cost and advanced frigate project for the navy, which was of great significance to the navy.
After it was raised at the Navy meeting, relevant technical personnel began to question the issue of diesel engine paralleling. Therefore, Wu Shengli took some time off and came here to seek a solution.
"Since 1978, we have introduced the PA6 series diesel engines from the French Thermal Engine Association, and are now able to produce related products, ranging from six to sixteen cylinders. However, we do not have relevant information on this STC technology, and , we can’t solve the problem of diesel engine paralleling.”
Wu Shengli nodded: "I have heard from technicians in the capital that if you want to drive two diesel engines with the same power in parallel to drive a propeller, it will be very difficult from a technical point of view."
"Yes, there is no such precedent in the world." Wang Tianmin said: "So, although we are very confident in our diesel engines, we are still cautious in this regard. Perhaps, Mr. Qin He is very capable and has a way to solve related problems. ”
Wu Shengli's expression was serious: "Yes, there is no precedent in the world, but with our current strength, when gas turbines cannot make breakthroughs for the time being, diesel engines are our most suitable solution."
If there are advanced gas turbines in China, why would there be so much trouble! Even if it is a little more expensive, you can just use gas turbines directly. In fact, some countries use full fuel power.
We are still far behind. Even if we make it in China, it has high fuel consumption and low lifespan, and it can't be used on ships at all.
"Director Wang, Bincheng Diesel Engine Factory called." At this time, a secretary whispered in Wang Tianmin's ear.
So, Wang Tianmin picked up the phone, pressed a button, turned the phone over, and then heard the voice inside.
"Boss Qin has visited me here and helped me a lot. He said that the plan for the vehicle combination has been prepared, and you need to provide relevant information about the diesel engine."
"The plan for the vehicle combination has been prepared?" Wang Tianmin was extremely surprised.
After hanging up the phone, he was very excited. Wu Shengli was there, smiling. Qin Tao had never let him down! Since Qin Tao said it was okay, it must be okay!
"It seems that I have to go to Mingzhou to have a look."
Wu Shengli said to himself. On the one hand, he wanted to listen to Qin Tao's report to see how the problem of the vehicle connection was solved. On the other hand, he wanted to see the anti-aircraft ship under construction to see how the progress was.
"I'll go too, to send information to Mr. Qin!" Wang Tianmin was also very enthusiastic.
For Wang Tianmin, Qin Tao solved the problem of vehicle connection, which meant that their diesel engines could be mass-produced.
This is not an ordinary automotive diesel engine. There are tens of thousands of units in demand every month. For large marine diesel engines, the monthly output is often in the single digits, and some even produce only one unit every few months. From the establishment of the factory to now, they have only produced about 500 marine diesel engines. If there are a large number of orders, it means that their income can be multiplied several times!
So, when Qin Tao came back from Bincheng, coordinated the production of new parts in Huating, and then rushed back to Mingzhou, a large group of people also came from the distant Old District Diesel Engine Factory.
"Dad, why are you here?" Qin Tao was extremely surprised when he saw Wu Shengli.
"Well, I heard that there is already a plan for diesel engine integration here, so I came to take a look." Wu Shengli said.
Heard? Qin Tao looked at those people wearing work clothes from the Old District Diesel Engine Factory again, and understood something in his heart: "You are just conducting research at the Old District Factory?"
"Yes."
"I just came back, and I don't know the specific progress. Let's ask our technicians to introduce it." Qin Tao said: "However, these technologies are under development and have not yet applied for patents, so please pay attention to confidentiality discipline."
Wu Shengli nodded: "If anyone dares to leak secrets, the Navy will investigate to the end."
For the Old District Diesel Engine Factory, no matter which shipyard wins the bid, it will not affect them. They don't need to leak the technology. Moreover, Qin Tao wants to use their diesel engines, which is good for them.
In addition to Wu Shengli's words, anyone who dares to leak the secret would be very bold.
"We have entrusted the research and development of this parallel car to researcher Zhang Chao, who is from Tsinghua University and has strong capabilities."
Wang Tianmin was left with only surprise and emotion.
Qin Tao's statement that he wanted to apply for a patent shocked him. Now, he heard that there was a top student from Tsinghua University here, which made him even more shocked. This Mingzhou Shipyard is really a place where hidden dragons and crouching tigers are hidden!
In the conference room, Zhang Chao was also very excited. He opened his notebook and typed the design plan on the screen.
Qin Tao only gave a suggestion at the beginning, but now Zhang Chao has designed the plan based on the specific performance of the diesel engine and his own needs.
Looking at the precise mechanical perspective, Wang Tianmin felt like Liu Laolao entering the Grand View Garden, everything was fresh.
"In theory, this plan is feasible, but you haven't received our technical information yet, how did you start the preliminary design?" After listening to the exquisite design, Wang Tianmin expressed his affirmation and also raised questions.
"We made the design based on the technical data of the STC diesel engine of the French Thermal Engine Association. After all, what we have to match in the end is this kind of diesel engine."
Now it was Wang Tianmin's turn to be embarrassed. They hadn't made this kind of diesel engine yet!
"In other words, this set of technology can realize the parallel operation of diesel engines?" Wu Shengli didn't understand these specific technologies, but he could ask people around him. Now it seems that this technical route should be feasible.
"Yes, it is completely possible. Even if a reduction gear is added on the side, this set of equipment can also realize the parallel operation with the gas turbine." Wang Tianmin said.
The design is too clever, especially the clutch, which is absolutely innovative. No wonder they want to apply for a patent!
"Then the next step is to make the machine and conduct a two-hundred-hour test run on land. If the test run is normal, it means that this set of technology can be used in the drive of frigates. In the future, all our frigates can use this power system!" Wu Shengli was also very happy and made the decision immediately.
"Leader Wu, we don't have this kind of STC diesel engine yet." Wang Tianmin reminded in a low voice.
This is to build a mechanism for paralleling. They want to build a diesel engine. Now they don’t have STC technology, how can they experiment?
“We have plans to use this kind of power for the ships we build for our customers. The French imported diesel engines will arrive soon. At that time, we will find a way to disassemble the turbocharger inside and then imitate it.” Qin Tao said: “At the same time, due to the increase in power, you also need to strengthen the relevant mechanisms of the engine, such as pistons, crankshafts, connecting rods, etc.”
Wang Tianmin frowned.
Qin Tao is right.
Adding a turbocharger to the engine will rapidly improve the performance of the engine, but at the same time, this way of squeezing power will also cause some damage to the engine, and the relevant mechanisms need to be strengthened.
Originally, it was 400 horsepower per cylinder. Now we want to increase it to nearly 500 horsepower. This requires strengthening all the relevant mechanisms!
How to strengthen?
"You can learn from the technology of MTU diesel engines. At the same time, introduce some new equipment and improve your production line. This is also an opportunity for you to leap forward." Qin Tao began to make requirements: "For example, in terms of casting, the world has begun to use resin sand molding production lines, so that the cast cylinder will be more precise and can withstand stronger impacts. For other parts, you also need a special processing center to improve precision."
Low-speed diesel engines rely on large volume and do not require high strength, but this kind of medium- and high-speed diesel engine is different. Qin Tao put forward the requirement of product upgrade to them. Only in this way can the needs of 4,000-ton frigates be met.
"Boss Qin, these improvements require a lot of money!" Wang Tianmin looked distressed.
"You can learn from Bincheng Diesel Engine Factory." Qin Tao said: "The god of machine manufacturing in the island country is doing research there. With only 5 million US dollars, you can complete the upgrade and transformation requirements for their production line. You may also be able to spend less money and do big things."
"But we don't even have 5 million US dollars." Wang Tianmin was very frustrated: "How can we compare with Bincheng Diesel Engine Factory?"
Bincheng Diesel Engine Factory produces low-speed marine diesel engines. In the current shipping market, 90% of cargo ships are equipped with this type of engine.
And their Laoqu Diesel Engine Factory produces medium- and high-speed marine diesel engines. Most of these are used to match warships. Now the domestic warship production is small. Although their factory was established during the First Five-Year Plan, it is now just trying to survive.
Moreover, their factory is still in the inland area, which is not comparable to the coastal area. They can't even take out 5 million!
Comparing people is annoying.
"If we use the factory's assets as collateral and borrow money from the bank without upgrading and transformation, we will definitely fall behind in the future and may be eliminated in the market competition." Qin Tao said.
"Mr. Qin, it's difficult to borrow money, and it's five million US dollars, which is foreign exchange." Wang Tianmin said: "We are not as rich as your Minnesota Shipbuilding Industry Group."
At this point, Wang Tianmin suddenly remembered something: "Mr. Qin, can you provide us with money?"
Of course not, my money is not blown by the wind, Qin Tao thought so in his heart, but in order not to hurt the other party's self-esteem, he did not say it.
However, Wang Tianmin's next words made Qin Tao happy: "If you are willing, we are willing to sell part of the factory's shares."
"You mean, we use the method of injecting funds to invest in your Laoqu Diesel Engine Factory?" Qin Tao did not expect that there would be such a good thing that fell from the sky.
