The rapid rotation of the grinding disc and the power from machinery are pushing Zhangjia closer to the door of industry, and it seems that it is only one step away from industrialization.

Zhao Baishi, Wang Xuhe, Li Mingfeng, He Zhengjie, and Bai Xiaodong started the competition with brand-new drawings.

In the manufacture of wind turbines, Bai Xiaodong's team takes the lead with assembly line technology. Not to be outdone, the rest of the groups developed their own production techniques.

Five steam turbines were built at the same time, which was supposedly unnecessary, but Zhang Hao insisted. Because, rush for time!

It is not only the time to build, but also the time to cultivate talents.

If you want to cultivate talents, you need practical skills.

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

"Bearing?" Huang Mingshan and the others thought thoughtfully.

Zhang Hao took an impeller machine of the original test model, pointed to the spindle and said, "See this?"

On the spindle, there is already a noticeable depression, which is caused by friction.

Huang Mingshan nodded: "Young Master, this situation is very common in carriages. I have observed many horse-drawn carriages, and their main axles are worn to varying degrees. This is something that spells are difficult to solve.

The commonly used method now is to make 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 in the carriage, it is still okay." But it is not enough for machines. Because, the speed of the wheels of the carriage is only more than 200 revolutions at most in a minute, and the speed is only 300 revolutions.

But our steam turbines are now at 500 rpm.

The pace will continue to increase in the future.

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

I have an idea about this. ”

"According to practical empirical observations, there is only a circle, and there is the least resistance in the process of moving forward. So, is there a way to add a 'circle' between the spindle and the shaft seat?"

As he spoke, Zhang Hao used round chopsticks to insert them between the spindle and the shaft seat.

This is the prototype of roller bearings.

A new study has begun.

In order to polish the rollers, everyone had to try to study machine tools, and 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, cutters, fixtures, reducers, etc., appeared, especially screws, which also came into being.

Just two days later, the first humble machine appeared. Its bearings are still slip rings, but it already has some basic functions of the machine tool. The knives of the machine tool are temporarily made in the way of refining magic weapons, and the hardness is very good.

Cylinders of dark iron are polished out and then precisely cut into one-centimeter-long cylinders.

The cylinder is loaded into a shaft ring, which is also machined with a machine tool.

In order to ensure the stability of the rollers, a bearing cage was added, which was stamped from a thin sheet of iron – needless to say, a rudimentary punch press was born.

The same was born, as well as mold technology.

After two days of sleepless hard work and hundreds of fumbles, the first bearing was finally tested.

The spindle is inserted into the bearing and then fixed to the shaft seat, and an iron ring weighing 300 catties is worn in the center of the spindle. Huang Mingshan rotated the iron ball hard, and the spindle rotated wildly.

There was no screeching sound, no squeak, it just turned silently, so fast, almost no slowdown!

It took more than half an hour to rotate before the spindle slowly stopped.

Everyone looked at each other, and then erupted in a frenzied cheer.

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 those specializing in the processing of screws and nuts.

A complete industrial foundation has finally emerged.

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

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

100 high-grade spirit stones, equivalent to millions of lower-grade spirit stones.

Everyone was stunned.

Huang Mingshan took the spirit stone, his hands trembling. He never imagined that he would one day be able to obtain such a rich fortune.

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

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

Yes, that's it.

What I have given you must be what you need, and it will far exceed your expectations!

Clapping his hands again, Zhang Hao said loudly: "Did this bit of wealth shock you?"

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

"Next, I will give you a task, which is to install bearings on all current steam turbines!"

Under the Reward...... It must be efficient.

Since the beginning of the study of steam turbines, Huang Mingshan and others, who have not had a good rest, hastily swallowed a few Peiyuan Dan and put them into production practice.

The technology is out, but there are still many problems that need to be solved if we want 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 the outside of the smelting base directly into the grinding discs.

Six steam turbines roared, six grinding discs rotated wildly, and ore, spirit stones, and even bamboo charcoal were all crushed and sent directly to the smelting furnace through a conveyor belt.

The conveyor belt machine is a small, spirit-stone-driven turbine, which is the diffusion and application of machine tool technology.

Gone are the small furnaces that were once small, and in their place are six large furnaces. To manipulate these bulky smelting furnaces, a pulley mechanism was used.

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

Underneath the smelting furnace, the flames fueled by spirit stones shimmered with golden light.

As he was looking, he saw a smelting furnace suddenly moving by the craftsmen. They pulled the iron cables and controlled the smelting furnace to pour the molten iron through pulleys.

Molten iron is bright red with a golden color, shining with the light of wealth.

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

Until Zhang Shengye came, he woke up Zhang Hao: "Little mouse, be spectacular." ”

"Second uncle, I should have asked you, right? ”

"Haha...... Yesterday, we paid for the Darkiron that we bought from the workshop. Dugu Junjie is taking all the craftsmen from the county town. It will be there in the afternoon. ”

Zhang Hao's eyes immediately flashed with light: Shipbuilding! A big ship made of dark iron! A big ship that can break through the green sea of death!

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

"Two hundred tons?"

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

It's only been a little over a month, and the Zhang family has undergone earth-shaking changes. This change is something that Zhang Shengye could never have dreamed of.

With a daily output of 300 tons and a monthly output of 10,000 tons, it is not a dream!

It wasn't until a furnace of molten iron was cast that Zhang Shengye spoke again: "Your father is going to turn into a baby!"

"What?" Zhang Hao was stunned.

"Your father, today is about to break through the Yuan Infant Stage. From today onwards, our family will also have a master of Yuanying!"
