Chapter 55 Production of 300 Tons of Black Iron per Day

The rapid rotation of the millstone, the power from the machinery, is pushing the Zhang family closer to the gate of industry; it seems that there is only one step away from industrialization.

The five groups of Zhao Baishi, Wang Xuhe, Li Mingfeng, He Zhengjie, and Bai Xiaodong started the competition with brand new blueprints.

In the manufacture of fans, Bai Xiaodong's team took the lead by virtue of assembly line technology. But the rest of the groups are not to be outdone, and they have developed their own different production technologies.

Five steam turbines were built at the same time; supposedly this was completely unnecessary, but Zhang Hao insisted on it. Because, to rush time!

What is robbed is not only the time for construction, but also the time for personnel training.

As the saying goes, true knowledge comes from practice; if you want to cultivate talents, you need practical skills.

And Zhang Hao has already led Huang Mingshan and others to start the next step of research.

"Bearing?" Huang Mingshan and the others were thoughtful.

Zhang Hao took an impeller machine of the original experimental model, pointed to the main shaft and said, "Did you see this?"

On the main shaft, there is already an obvious depression, which is caused by friction.

Huang Mingshan nodded: "Master, this kind of situation is very common in carriages. I have observed many carriages, and the main shafts will be worn to varying degrees. This is difficult to solve by magic.

The method commonly used now is to refine a pair of slip rings with low-grade black iron, and fill the slip rings with butter. "

Zhang Hao also nodded: "Yes, this method can be used on a carriage, but it is not enough to use it on a machine. Because the wheel speed of the carriage is at most two hundred revolutions per minute, which is not too fast. Three hundred turns.

But our steam turbines are now rotating at 500 rpm.

The speed will continue to increase in the future.

At very high speeds, slip rings are no longer up to the task.

I have an idea about this. "

"According to actual experience and observation, there is only a circle, and the resistance is the least in the process of advancing. Then, is there a way to add a 'circle' between the main shaft and the shaft seat?"

As he spoke, Zhang Hao inserted round chopsticks between the main shaft and the shaft seat.

This is the prototype of the roller bearing.

A new study has begun.

In order to polish the rollers, everyone had to try to study machine tools; in order to study machine tools, they had to study small engines that could be driven by spirit stones.

Then, gears, guide rails, rotating shafts, knives, fixtures, reducers, etc. appeared one after another; especially screws, also came into being.

Only two days later, the first crude machine tool appeared. Its bearing is still a slip ring; but it already has some basic functions of the machine tool. The knives of the machine tools are temporarily made in the way of refining magic weapons, and their hardness is very good.

Black iron cylinders were polished one by one, and then cut precisely to become one centimeter long cylinders.

The cylinder is fitted into a collar that is also machined.

In order to ensure the stability of the rollers, a bearing cage was added, which was punched out of thin iron sheets—needless to say, a simple punching machine was also born.

The same was born, as well as mold technology.

After two days of restless efforts and hundreds of trials, the first bearing finally passed the test.

The main shaft is inserted into the bearing, and then fixed to the shaft seat; an iron ring weighing three hundred catties is worn in the center of the main shaft. Huang Mingshan spun the iron ball vigorously, and the spindle spun crazily.

There is no harsh friction sound, no creaking sound, it just rotates silently, rapidly, almost without slowing down!

After turning for more than half an hour, the main shaft slowly stopped.

Everyone looked at each other, and then burst into wild cheers.

Zhang Hao stood on the podium of the brand new research room, quietly looking at several machine tools on the ground of the research room.

Punching machines, grinding machines, milling machines, cutting machines, drilling machines, and special processing screw nuts.

A complete industrial foundation has finally emerged.

Zhang Hao clapped his hands, and someone came in immediately. Rich rewards are placed in front of everyone.

"Each person, top-grade spirit stones, 100!"

100 high-grade spirit stones are equivalent to a million low-grade spirit stones.

Everyone was stunned.

Huang Mingshan took the Lingshi, his hands trembling. He never thought that one day, he would be able to obtain such a huge amount of wealth.

One hundred high-grade spirit stones, this is a wealth that is difficult to achieve in many foundation building periods! Even many Golden Core Stages may not have such wealth!

Zhang Hao looked over slowly, with a satisfied smile on the corner of his mouth.

This is what I want.

What I give you must be what you need, and it far exceeds your expectations!

After clapping his hands again, Zhang Hao said loudly, "Is this little wealth shocking you?"

Huang Mingshan and the others slowly raised their heads, their eyes gradually cleared up, but the eyes they looked at Zhang Hao became more and more fanatical.

"Next, I have a task for everyone, which is to install bearings on all the current steam turbines!"

With heavy rewards... there must be efficiency.

Huang Mingshan and others, who hadn't had a good rest since they started researching steam turbines, swallowed a few Peiyuan Pills hastily, and put them into production practice.

The technology has come out, but there are still many problems to be solved in order to apply the technology to practice.

Walking out of the research room, Zhang Hao climbed to a high platform and quietly looked at the magnificent smelting base in front of him.

The current smelting base has completely changed.

Several long conveyor belts continuously feed ore from outside the smelting base, directly into the millstone.

A total of six steam turbines were roaring, and six millstones were spinning crazily. The ore, spirit stone, and even bamboo charcoal were all crushed and sent directly to the smelting furnace through the conveyor belt.

The conveyor belt machine is a small turbine driven by spirit stones; this is the diffusion and application of machine tool technology.

All the small smelting furnaces that used to be there are gone; in their place are six large smelting furnaces. To maneuver these heavy smelting furnaces, a pulley mechanism was used.

Next to each smelting furnace, there are eight fans blowing air.

Below the smelting furnace, the flame fueled by spirit stones shone with golden light.

Just looking at it, I saw a smelting furnace suddenly moved by the craftsmen. They pulled the iron chain and controlled the smelting furnace to pour molten iron through pulleys.

The molten iron is bright red with golden yellow, shining with the light of wealth.

Seeing the molten iron splashing and pouring molds one after another, Zhang Hao was a little crazy.

Until Zhang Shengye came and woke Zhang Hao up: "Little mouse, it's spectacular."

"Second Uncle, I should be the one asking you."

"Haha... Yesterday, we paid for the purchase of the workshop's black iron. Dugu Junjie is taking all the craftsmen away from the county town. They will arrive in the afternoon."

Immediately, Zhang Hao's eyes flickered with light: shipbuilding! A big ship made of black iron! A big ship that can break through the green sea of ​​death!

Zhang Shengye continued: "Little mouse, do you know how much black iron we produced yesterday?"

"Two hundred tons?"

"No, three hundred tons! Three hundred tons of black iron with a maximum purity of 96%!" Zhang Shengye's tone was full of emotion.

It has only been more than a month, and the Zhang family has undergone earth-shaking changes. This change was beyond Zhang Shengye's dream.

It is not a dream to produce 300 tons per day and 10,000 tons per month!

When a furnace of molten iron was poured, Zhang Shengye said again: "Your father is going to be transformed into a baby!"

"What?" Zhang Hao was taken aback.

"Your father, you will break through the Nascent Soul stage today. From today onwards, our family will also have a Nascent Soul master!"
