Chapter 716 Poaching

Although Chang Haonan said that he was just throwing out some ideas, Lin Jingtang has been immersed in process numerical calculation for many years after all, and he is basically the type who can understand it at a glance.

Even if we only look at the theoretical calculation content on the drawing board, this seemingly ordinary new algorithm can greatly reduce the amount of calculation in the velocity field solution process, which happens to be the relatively time-consuming part of the entire calculation process.

Unfortunately, the 112 factory has not yet sent the specific process parameters, so more specific calculation steps are not available for the time being. For the time being, we can only test the universality of several classic volume incompressible conditions under this problem from the perspective of theoretical model research.

"In addition, Mr. Chang, before the equipment is officially powered on and started, we need to test the working status of the hydraulic synchronous deviation correction system separately..."

"The fatigue analysis and reliability detection system we are responsible for is currently performing open-loop testing..."

"The stroke sensor measurement system of the main working hydraulic cylinder..."

"..."

Under the command of Chang Haonan, the progress reports of each subsystem and the next work plan were summarized one by one.

In his mind, a relatively accurate and complete schedule gradually formed...

"To sum up, most of the work items in the cold state have been completed, and only one synchronous correction system needs to perform a separate open-loop test."

Chang Haonan raised his head and shifted his gaze from the notebook in front of him to the several responsible personnel on both sides of the conference table:

"How is the power supply situation in the new factory area? Has there been any power outage or voltage instability during the construction process?"

If it were more than 20 years later, such problems would hardly need to be worried about, but in this era, we are still on the eve of a major upgrade of the power system. Although power outages in an entire city cannot be said to be a daily occurrence, they do happen from time to time.

Many high-end residences even generally have their own diesel engines.

However, for super-large equipment like die forging presses, and surrounded by an entire new factory area of ​​Jiangzhong, the power consumption level after working is quite terrifying. Relying on self-provided emergency diesel generators is a drop in the bucket, so the local power supply must be guaranteed.

Yan Yongnian has been in the factory since about a year ago, and has not left, including this year's Spring Festival. Naturally, he is the most qualified to answer this question:

"At the beginning, we shared the power supply network with the neighboring Tuan County. There were still many problems during that period. However, later, the local government of Jiangcheng designated our area as an industrial new zone and approved a special power supply line. It is not affected by the urban power use plan, and the voltage stability and power outage frequency have been greatly improved."

"The last unplanned power outage here should be in February this year. Before the Chinese New Year, the power supply line from the substation was broken by ice accumulation. It took about 30 hours to restore it."

"For occasional power supply shortages, we considered this aspect when designing it. The safety locking system is in power-on release mode, so there is no need to worry too much."

At the turn of the century, if the power grid faces the risk of overload, it will generally choose to give priority to industrial power.

This is completely opposite to what happened later.

Therefore, having a dedicated power line can basically avoid most power supply problems.

"This kind of power outage caused by force majeure is acceptable, as long as it does not occur frequently and affect production." Chang Haonan nodded slightly: "Since there is no problem with the power supply, then we will tentatively schedule... May 13 to carry out the first power-on test of the equipment. If no problems are found in the self-test and external inspection, then on May 15, we will start preheating the hydraulic equipment and officially enter the equipment startup process. Is there any problem?" "No!" The other people answered in unison. "Then let's end the meeting today, adjourn the meeting!" After the meeting, Chang Haonan found Yan Yongnian alone in the factory who was on a routine inspection of the workshop. For Chang Haonan, the die forging press is just one of the two large projects he is carrying out at the same time, but for the latter, it is a career that he has been fighting for most of his life and almost missed. It is not an exaggeration to say that it is a lifelong effort. Therefore, in terms of the degree of concern, it is higher than Chang Haonan, the chief designer. The two stood on the visual inspection table on the second floor of the workshop, watching the workers not far away climbing up and down on the jig, installing some auxiliary equipment that was finally in place, as well as decorations that did not play a practical role.

For example, the four huge Chinese characters "Jiangcheng Heavy Machinery".

For a super-heavy die forging press, which is a treasure that there are only a few in the world, let alone just writing the manufacturer, Yan Yongnian even proposed whether to give it a name similar to a warship.

In the end, it was rejected by Chang Haonan because it was too childish.

"I didn't expect that in two years, a building could really be built from scratch, and this equipment could be built from scratch..."

Yan Yongnian pushed the brim of his safety helmet with the antenna of the walkie-talkie in his hand, and said to Chang Haonan who had just walked up next to him:

"It's a pity... Mr. Shen didn't see this day."

The design of this 75,000-ton die forging press, as well as a considerable part of the technology, were all based on a 68,000-ton prestressed steel wire winding die forging press developed by Qinghua University in the late 1980s.

Academician Shen Hong was the person in charge of the project at that time and also Yan Yongnian's teacher.

Chang Haonan also made a special trip to visit before the die forging press project was established.

In May 1998, Shen Hong passed away at the age of 92.

At that time, we were in the most critical stage of transforming the equipment from drawings to physical objects. Therefore, Yan Yongnian, who was too busy with anything to do, did not even make it to attend the other party's funeral.

Looking at Yan Yongnian who was thinking about people after seeing things, Chang Haonan felt that the effect of simple words of comfort might be average.

Moreover, he really hopes that this legendary academician with a primary school education who has worked hard for China Machinery all his life can be remembered by more people, at least more practitioners:

"I propose that after this die forging press completes its first trial production, the remaining parts of the blanks can be used to erect a bust of Academician Shen in the Jiangcheng factory to commemorate the work he has done for this die forging press. efforts and contributions.”

Yan Yongnian suddenly turned his head to look at Chang Haonan, his eyes trembling.

After a while, he nodded:

"good."

Then the two of them walked off the examination table one after the other.

"Professor Yan."

After walking around the workshop for a few more times, Chang Haonan directly performed a show:

"I remember that you have several doctoral students who participated in the entire numerical calculation process of our project. Are any of them graduating this year?"

"There are two graduates this year."

Yan Yongnian replied almost without thinking, obviously not realizing the seriousness of the problem:

"Why do you ask this suddenly?"

Chang Haonan was not prepared to conceal his purpose:

"After I graduate this year, I plan to set up a laboratory of my own. Of course, it will be based on the model of school-enterprise cooperation between Beihang University and Torch Group. Now there is a shortage of manpower, especially graduate tutors."

"Hiss... If you don't tell me, I will almost forget that you haven't graduated yet..."

Now Yan Yongnian understood.

This is to poach him...

However, because of the foreshadowing just now, if he refuses now, it will seem too inappropriate.

So, after hesitating for a moment, Yan Yongnian nodded:

"After they go back, I'll ask them to submit their resumes to Beijing Airlines... Anyway, they have experience in this project, so it shouldn't be difficult to pass..."
