Siheyuan: Craftsmen of a Great Country

Chapter 386 Grasp the progress of high-speed steel
After dinner at Feng Ping's place, the family returned to the courtyard.

But summer is here, and when I get home, it’s still quite bright.

Due to the hot weather, as soon as they returned home, the women took off their disguises one after another, each wearing cooler clothes than the other.

The random flowers were becoming more and more charming, making Jiang Chen's heart skip a beat.

Especially Zhao Qi.

Just wear a bellyband and underwear, and jump around the room.

Viewed from the front, it looks trembling and towering.

Looking from behind, it looks like she's not wearing any clothes.

Jiang Chen was a little distressed: "I'm talking about these beauties, could you please pay attention to your image?"

"What would you say if someone came in and saw you like this?"

Luo Xue said: "The core is that our hardware is not enough to support the continuation of precision research."

Zhao Qi groaned: "Asshole, you don't follow martial ethics."

Zhao Qi said coquettishly: "It's hot."

"And you two, don't run away. Wait there, you both have a share."

After saying that, he grabbed Zhao Qi's arm, twisted her up, and pressed her directly on the table:
"Xiaoyue, close the door, let's take a rest."

Liu Yue rolled her eyes at Jiang Chen and quickly closed the door.

Jiang Chen said: "It won't hurt later. If I let you hook up with me, this is what will happen."

Zhao Qi snorted: "I don't know how blessed I am. You actually want to refuse such a beautiful scenery."

On Monday, after Jiang Chen put away his car, he came to the place where Luo Xue was studying precision machine tools.

"I will try my best to meet your requirements."

Jiang Chen said: "It's okay. You will forget about the hot weather later."

"Be gentle, it hurts!"

Jiang Chen said: "What is the main limitation on your research?"

After saying that, he unplugged the eye-catching gadget and started the battle mode directly.

Luo Xue raised her head: "It's almost reaching its limit. Under the current conditions, it is difficult for me to continue to improve the accuracy of the machine tool with my ability."

"If someone comes, why don't you stop them and we hide in the back room?"

"The biggest limitation is the cutting tool. Even if it is made of tungsten-chromium alloy steel, the operating accuracy is still insufficient."

Looking at Luo Xue who was lowering her head and concentrating on research, she asked: "Xiaoxue, how is the progress here?"

Jiang Chen nodded: "Yes, I understand."

Jiang Chen sneered: "Hey, you are so arrogant."

"I got a new alloy steel formula, I guess it may be high-speed steel. Once it is developed, it should be helpful to your research."

Luo Xue's eyes lit up: "High-speed steel?"

"If I have the tools made from it, I should be able to easily meet your requirements and make an IT5-level precision machine tool."

Jiang Chen said: "Don't push yourself too hard. IT level 5 is just my expected precision level, not a mission indicator."

"You have to pay attention to protecting your body, especially your eyes. This is more important than anything else."

Luo Xue nodded: "Yes, I know! I still want a baby, so I will definitely protect my own body."

Speaking of the baby, Jiang Chen sighed secretly.

There is a long way to go.

So far, the stomachs of several girls have not reacted at all.

After coming out of Luo Xue, Jiang Chen went straight to the steel-making furnace. Lu Yuehua and Chen Tongshan are leading a team to develop alloy steel according to the formula using the steelmaking furnace in the laboratory.

Now they are using Jiang Chen's methods to research alloy steel.

After the team returned to Sijiu City, they first sent the exotic steel they brought back to a specialized agency for testing.

Find the unusual elements.

They were not idle during the testing.

Use the time waiting for results to conduct experiments on the optimal ratio of various elements.

When making steel, a single element is added and the optimal ratio of this element in the steel is calculated through three-point positioning.

At the same time, we can also get the main effect of this element on steel, whether it is to increase the hardness, make it more resistant to high temperatures, or something else.

When the test results come out, alloy steel can be made by combining multiple elements according to the optimal ratio.

However, in order to avoid mutual interference between different elements, it also needs to be developed three times.

Then calculate based on the results.

Calculate and then experiment, and so on.

Until the optimal ratio is obtained, alloy steel is successfully developed.

Yes, this research work is an infinite repetition of calculations and experiments.

Originally, he was planning to leave the development of high-speed steel to these two people.

However, in order not to affect the research progress of Luoxue Precision Machine Tools, he decided to do it himself and speed up the development progress.

Looking at the two people who were holding notes and directing the steelmaking experiment, Jiang Chen asked: "How is the progress?"

Chen Tongshan said: "It took some time to mobilize resources at the beginning. I just completed the experiment on the optimal ratio of all elements but the materials two days ago."

"Then I tried to refine several furnaces of alloy steel, and found that this steel is extremely hard, has good heat resistance and wear resistance, and is simply tailor-made for high-quality knives."

"However, we also encountered many problems during the steelmaking process."

"Especially this kind of steel involves many elements, and each element has a different melting point. It cannot be produced at a uniform temperature, otherwise some elements with a relatively low boiling point will be vaporized or undergo qualitative changes."

"This has brought huge tests and challenges to our temperature control."

Lu Yuehua said: "We gradually added in various elements from low temperature to high temperature according to their temperature tolerance, and managed to refine two furnaces of steel."

"Although it is still far from success, these two batches of steel have already demonstrated superior performance."

"We will continue to experiment and find methods in the future, and strive to develop this alloy steel as soon as possible."

Jiang Chen said: "Actually, your method of adding rare metal elements is already wrong."

"When the temperature rises, the first substances you add cannot withstand the high temperature and may have changed or lost their effect."

"Think about it, is this true?"

"Damn it!" Lu Yuehua slapped his forehead: "We two are really pigs, we didn't even think of such a simple truth."

This is probably the true confusion of the authorities.

According to their abilities and thinking, they should be able to figure this out easily.

Probably because there were too many problems encountered during the experiment, this problem arose.

Chen Tongshan said: "So, we should change the method. First, increase the temperature, add a substance with strong temperature resistance, wait for it to merge with the molten steel, and then gradually lower the temperature and add other elements."

Lu Yuehua nodded: "Yes, I didn't know which elements were wasted before. The quality of this steel can definitely be greatly improved."

Chen Tongshan said: "It is said to be so. According to the performance of this steel, I feel that this formula may be the formula of this alloy steel."

Lu Yuehua said: "What kind of alloy steel?"

Chen Tongshan said: "High-speed steel!"
