Chen Lidong handed Gushen Angong Pills to Edmund for testing. He first tested whether the chemical components in the pills contained harmful substances such as lead, mercury, arsenic, etc., and then found someone to analyze the properties of the drug.

In the end, even if there is no problem, he will not eat it.

Based on his experience in another life, Chen Lidong always believed that the two of them had no physical problems. As for their long-term infertility, it might be...a problem with posture.

......

As for Zheng Xiaomin's matter, it is a bit complicated.

One night shift, he stole a few pieces of steel pipes from the pipe workshop, which were used as shaft outer rings.

This was his second time to cut off the steel pipe. He sawed several pieces of the steel pipes with a hacksaw and clamped them in his work clothes to take them out of the factory.

In fact, when I first found that there was a piece of steel pipe missing, the warehouse manager had already reported to the security department.

Zheng Xiaomin did the second time, he was recorded by the newly installed surveillance equipment.

So after the factory received the report for the second time, it checked the surveillance and found Zheng Xiaomin.

Zheng Xiaomin charged him two thousand yuan for stealing steel pipes.

The money was given to Jishi Yingsheng Trading Company, which has a business relationship with a company under Sun Guochun Group.

In 2000, Huaxia formulated the national standard "High Carbon Chromium Bearing Steel" gb/t18254-2000, and Donghua Steel began to tackle bearing steel in accordance with the newly promulgated standards.

Bearings are known as the "heart of industry". The bearing industry also has the term "National Economic Equipment Department", so Chen Lichun has been preparing to develop bearing steel and produce bearings that are comparable to the world's standards.

Donghua has unique advantages in producing bearing steel because it can obtain ultra-precision chemical composition billets based on Far East Steel.

However, with Chen Tianchang being transferred, it was actually because the system furnace was busy eating rare earths and gold concentrates, and Far East Steel Plant no longer provided those billets.

When Donghua smelted high-carbon chromium bearing steel, it has to face the problem of upgrading the entire process from steelmaking to rolling.

Fortunately, the group established the Metal Research Institute two years ago. Under the request and supervision of Chen Lichun, under the guidance of the research institute, Yin Fumao led a group of people to work hard for more than half a year and finally produced high-carbon chromium bearing steel that exceeded the national standards.

The secret to smelting high-carbon chromium bearing steel lies in formula and quality control. The key is that the billet is pure, there are few inclusions, and high product consistency.

The first thing to do for the purity of steel is to control the oxygen content in steel. In steelmaking, ppm (one per million) is used as the unit of oxygen content. Generally speaking, 8 ppm steel is good steel, while high-end bearings require 5 ppm top-grade steel.

In addition, harmful elements such as titanium are easily formed in the steel, which will cause local stress concentration and fatigue cracks. These elements should be avoided as much as possible.

In addition, under the prompts of the Metal Research Institute, Yin Fumao added an appropriate amount of rare earths during the rolling process of steel.

This is a common practice for famous bearing steel companies in the world, but how much to add and how to add has always been the core secret of major bearing steel companies.

Now Donghua’s bearing steel has also made the original high-quality steel more "stronger" by adding rare earths, which has attracted the attention of foreign steel companies.

After the bearing steel is rolled, it must be annealed.

Zheng Xiaomin committed the crime twice, intercepting the bearing steel before and after annealing, and using Yingsheng Trading as a sample, and finally provided it to Chunben Company.

These bearing steels were originally to be sold to ordinary customers, but as for the steels that Chen Lidong said were rolled for the troops, they were actually scaring people.

If special military steel is really produced, military representatives will be arranged to be stationed in the factory to supervise the production process. Ordinary employees like Zheng Xiaomin will definitely not be able to steal such steel.

Now, Zheng Xiaomin's approach is not simply a piece of steel, he is just doing business spies.

Donghua is a supplier of several major military-industrial enterprises, and these bearing steels will also be provided to those military-industrial enterprises. Donghua said that Zheng Xiaomin steals military-industrial products and steals state secrets, which is also related to it.

Therefore, what awaits Zheng Xiaomin will be the iron fist of the proletariat's dictatorship.

The legal person and specific agent of Yingsheng Trading have been controlled and are under investigation.

Zheng Xiaomin's monthly income can reach an average of 4,000 yuan, and two thousand yuan can make him lose his freedom for several years. It can only be said that there is too much water in his head.

Yin Fumao chose to call the police at that time to kill someone to warn him.

What was stolen this time was not military products. If so, he would be the first to be dealt with.

These matters have been handed over to the public security and security departments to handle, and Donghua will do whatever he should do.

For example, Chen Lichun, after taking down the bearing steel mountain, began to tinker with bearings again.

When Chen Lidong looked at the ingredients of Gushen Angong Wan and got angry, Chen Lichun was also sighing at the test report in his hand.

A research institute of the Metal Research Institute handed him a metallographic inspection and analysis report on the material of a shaft sleeve.

This sleeve is not the type intercepted by Zheng Xiaomin, but is used on a 6-7-meter-diameter shield machine. The outer ring diameter of the sleeve is 2.6 meters.

The research institute analyzed the fracture structure of the shaft sleeve material and compared it with the original shield machine shaft sleeve material, and found that the material of its own material and the cross-mesh carbide are unevenly refined, which is a tissue defect, which is a high probability that the subsequent quenching will be insufficient and ultimately affect the service life of the bearing steel.

The suggestions given by everyone in the institute are: refine the rolling process, pay special attention to temperature control and cooling processes.

The Metal Research Institute has been established for two years and has played a great role in improving the production process of the steel plant.

This time, the fracture tissue analysis was to look at the sections with a metallographic microscope and then issue a test report.

This report is like going to a hospital to take a CT, with a large picture and a small conclusion.

How to control the temperature?

After the steel of high-carbon chromium bearing steel comes out, how to roll it into a material next?

Should I heat it to 1200 degrees or 1300 degrees? Should I knead the dough after 1000 degrees, or should I start drying at 900 degrees?

Chen Lichun sighed. It was time-consuming, labor-intensive and expensive to study this.

In order to roll high-carbon chromium bearing steel, the molten steel needs special smelting, and an appropriate amount of niobium is required to make high-strength, high toughness, and high oxidation resistance steel.

At the same time, the rolling line needs to be shut down and the temperature is readjusted before operation can be started.

This has been a few days.

The special steel processed by the steel plant is now in short supply, and Chen Lidonglan bearing steel occupies a line, and Yin Fumao is already full of complaints.

He thought he could practice bearing steel, and Chen Lichun would be at peace for a while, but unexpectedly, he immediately studied the spindle bearings of the shield machine.

When I saw Chen Lichun sighing with the report, I didn’t need to look at it and I knew that all the batch of steel rolled yesterday had failed.

What a pity, that's all money.

You know, for comparison, 9 batches of steel were rolled separately. One experiment was consumed by millions.

Any success in this batch can also make people overjoy.

Yin Fumao advised: "Dachun, why don't we take a break first.

I want to say, why do you do that?

How many shield machines can I buy in China a year? Even if I need ten or twenty units a year, it is not cost-effective to make bearings for them.

Let them spend more money, can foreign manufacturers not sell them?"

Chen Lichun said: "Xiaodong said that people really don't sell it. Foreign manufacturers are not bad at all. Once they sell it, they can buy it for tens of millions."

Yin Fumao said: "Then we will develop a shield machine and sell it like this? It will definitely not work. We will be scolded to death in China. So, it is really useless to study this."

Chen Lichun said: "Lidong told us that we must complete it. My younger brother's idea must not be wrong.

The idea he proposed was to remanufacturing the shield machine, which was to remove the used shield machine, replace the accessories and then use it.

The shield machine spindle is the easiest to consume, and we must overcome this difficulty."

Yin Fumao said: "Oh, it's better to use that production line to make strips.

I guess more people will build houses this year, and more profitable production of strips will be."

Chen Lichun threw down the report in his hand and said, "Brother, you have a net worth of tens of millions at least, haven't you made enough money yet?"

Yin Fumao said: "Is there enough money to make? I have to save money for your nephew to study abroad."

Chen Lichun joked: "That's enough, right? Do you want to raise your sister-in-law abroad?"

Yin Fumao said: "I'm afraid you won't believe it when I say it. I don't have a penny in my pocket.

All the salary was paid by Yao Huizhen. Yesterday the accountant came to me and said that the students I helped would need to pay a living expenses when they went home during the New Year. I couldn't borrow 3,000 from the company's account and could only be deducted from my salary next month. Now I can't afford to change my phone.

I put all the dividends in the group account, and Luo Hao took them all for investment.

It is said that the group's debt is getting high, and the three of you are going to pay the money."

Chen Lichun asked: "Are you afraid of losing all the money?"

Yin Fumao said: "It's just light. You dug me a bachelor. Can you still pay me in if you pay me?"

Chen Lichun laughed and said, "I've lost all my money. Let's be a duck. Your body must have earned more than me."

The two brothers said it was just talking, laughing was just laughing, and they had to do the work.

Yin Fumao gritted his teeth and arranged to roll 9 batches of steel tomorrow.

In fact, even if the temperature control of this batch of steel is in place and there is a light of dawn, the next step is to study the problem of heat treatment.

There is no shortcut to scientific research, so you have to keep trying and making mistakes. If you try, you may succeed.

It’s really hard to afford to play in ordinary factories like this.

It took Chen Lichun and Yin Fumao more than half a year to tinker with high-carbon chromium bearing steel. The money wasted was tens of millions, and now they are using the money to keep wasting water.

However, selling high-carbon chrome bearing steel is really profitable, with a starting price of 8,000, and some profiles can even be sold for more than 10,000 yuan. The value added after processing into bearings is even higher.

Now, Chen Lichun misses Xiao Holov and Chen Tianchang very much. They are steelmaking masters, stronger than Yin Fumao. But it is said that Chen Tian grew up to the governor of the northernmost state in the Far East, and Xiao Holov has also reached the point of not listening to the tune and not listening to the announcement.

It would be fine if Chen Tianyi was there, but Tianyi was pulled by Li Taishun to develop a lithium battery film coating machine and winder.

I have to tell my brother these days why Chen Tianyi always sent it to Li Taishun, I am your biological brother, so why doesn’t he behave with his biological brother? If it really doesn’t work, I will arrange some assistants for my brother...

In 2001, Chen Lidong's panic became even stronger because of the industrial assistant system.

He found that the system's equipment redemption platform could not be kept updated.

In the past, every time the main task was completed, the system could be upgraded, and the equipment redemption platform could be updated. Blue Star registered a patent and disclosed the information to complete the equipment.

What about now?

I have a 10-year main task that cannot be upgraded one level a year.

This system only gives the host a novice period of about 5 years. After the deadline, you can only rely on yourself to obtain advanced equipment.

By relying on oneself, one must focus on research and development and constantly explore.

Fortunately, there are only a few shortcuts, and the equipment developed by oneself or plagiarized equipment can be included in the redemption list.
