"Xiao Zhao, you really have something hidden." Ma Hanxing's eyes burst into sharp light again. After only a second, the light light turned into encouragement and care from the leader: "It doesn't matter whether to hide or not. What's important is that we have made a breakthrough under laboratory conditions. If the theoretical extreme value is also broken through in industrial production, Xiao Zhao, you are the biggest hero. Xiao Zhao, thank you for your hard work, you must pay attention to your health. Go home and sleep quickly. You are allowed to leave for a day and see you tomorrow."

"Okay, then I'll leave, see you tomorrow."

Zhao Qingshan said goodbye and left, and needed to leave for Ma Hanxing and Zhou Tienan to digest and absorb the freshly released experimental data.

In order to verify that the experimental data is not made up, Ma Hanxing and Zhou Tienan did it step by step based on Zhao Qingshan's experimental records, and continued until late at night.

The two's experimental results were consistent with Zhao Qingshan's. The experiment under such laboratory conditions was repeated for a week.

Stable laboratory data provide compelling evidence for industrial production.

The similarity between laboratory and industrial production is that the formula is still the formula and the taste is still the same.

The difference is equipment and materials. The delicate and gentle oven has become a huge and wild heating furnace, and the pocket-sized test silicon steel slab is replaced by mass-produced silicon steel slabs weighing dozens of tons.

Accurate control under laboratory conditions cannot be reduced 100% in industrial production, so data under laboratory conditions are often overwhelming, but there are certain differences in industrial production.

What creates benefits is industrial production, and the laboratories in enterprises serve benefits and industrial production.

When Director Ye Guoli saw the experimental data, his first reaction was surprised: "You three cobblers have at least half of Zhuge Liang."

Ma Hanxing patted Zhao Qingshan's back: "Xiao Zhao is an outstanding talent and has the highest contribution."

"It's too early to say that, I want to make a big question mark. The contribution is linked to industrial production. If industrial production is successful, you are really successful. I will immediately call Director Wu of the hot rolling factory and arrange a test for mass production of silicon billets for the No. 3 furnace as soon as possible." Ye Guoli arranged this way. It is a big deal to transfer experiments to production, and the production workshop needs to agree and cooperate.

The project task book had been sent to the hot rolling factory long ago, and Director Wu said there was no problem.

Everything is ready, and the next step is to choose a zodiac auspicious day.

Because of the inherent characteristics of oriented silicon steel, liquid slag is constantly generated during the firing process and accumulated at the bottom of the furnace. When the liquid slag accumulates to 300mm, the slag must be stopped to discharge, otherwise the liquid slag will overflow the column dam and flow into the water sealing tank at the bottom of the furnace, causing explosion.

Although the No. 3 furnace of the hot rolling mill has never exploded, this safety hazard will always exist. Once it is exploded, the furnace will be destroyed and people will be killed, with heavy losses and unimaginable consequences.

At the same time, the refractory materials in the cross beams, columns, furnace bottom dikes and other parts of the No. 3 furnace have also suffered severe erosion and need to be replaced regularly.

Safety is the first priority for production. Without safety, there is no production.

The work of repairing furnaces is related to human life and national property. The current situation of the No. 3 furnace of the hot rolling mill is to burn 5,000 tons of oriented silicon steel every month, then shut down the furnace for 15 days to repair the furnace, and then resume production, and this cycle is carried out.

The No. 3 furnace is currently under maintenance and production is expected to resume on October 25 to burn the next batch of 5,000 tons of oriented silicon steel.

Early in the morning on October 25th, Ma Hanxing, Zhao Qingshan and Zhou Tienan came to the hot rolling factory.

A large group of people in the hot rolling mill were waiting here. They were Director Wu, Workshop Director, Equipment Section Chief, Gong Zhang, and several work section chiefs/workshop technicians.

"Three experts, you are waiting for you!" Director Wu shook hands with the three experts from the Steel Research Institute one by one, talked less and got straight to the point. He immediately ordered the furnace to open the furnace and spray paint.

The repaired No. 3 furnace is started normally. The cleaned silicon steel slab is lifted onto the rollers by a 40-ton half-door type, and sent to the inlet of No. 3 furnace, and the material rack is pushed with a steel pusher.

When heated to 300 degrees, the sprayer sprays aerosol-like coating covering the surface of the silicon steel slab.

The laboratory spraying device is a small spurt and a small spurt cannon, while the No. 3 furnace industrial spraying machine is a real sword, a real gun, a long pipe cannon.

The liquid coating in the coating tank was replaced by the silicon-silicon carbide system of Nihonite to the magnesium oxide-dichromium trioxide system independently developed by the Steel Research Institute's laboratory.

This furnace is heated to 1320 degrees and needs to be kept in heat for 5 hours.

“Sample sampling!”

Three experts from the Steel Research Institute shouted, and Director Wu ordered the workers in front of the furnace to get the silicon steel samples of the No. 3 furnace.

This is a sample produced by industrial production. Some tests can be made in hot rolling mills, while some need to be taken back to the Steel Research Institute for further analysis.

"It should be no problem, right?" Director Wu asked with concern.

Zhao Qingshan replied: "After spraying our new paint, the second layer of the main crystal phase with the second layer is a solid solution and also contains a small amount of mafen peridot phase with a higher melting point. Only this preliminary conclusion can be obtained at present."

"Mr. Zhao, just tell me directly that there is a problem or not." Director Wu was afraid of problems, but he was eager to solve another problem. People are greedy.

"I can only say that the protective effect has been formed. Whether the silicon steel in this furnace will be scrapped will be found in a few hours." Zhao Qingshan was still a little nervous. This furnace of silicon steel has dozens of tons. First of all, we must ensure that the quality of the oriented silicon steel with the new coating sprayed is not affected. Let's study whether the furnace has become more durable.

"You must not have quality problems, you can't get it." Director Wu was walking around the three experts from the Steel Research Institute, with great worries. He had no house in Jianggang, so he took the initiative to give the quota of housing to the workers. He traveled to Hankou and Gangcheng every day. He came early and left late, and could not sleep for a few hours and was worried about the hot rolling factory.

The furnace becomes stronger, but the silicon steel becomes weaker, which means putting the cart before the horse and it is absolutely impossible.

If this furnace of silicon steel is scrapped, the problem will be too serious.

This means that all the efforts of Zhao Qingshan and the other three during this period are in vain.

Not only is it in vain, but it also has to bear responsibility.

If workers make scrap steel, they will deduct wages and bonuses. In more serious cases, they will be transferred from front-line production positions and sent to the bathhouse to collect tickets.

The same goes for engineers who make mistakes.

It doesn’t matter if you deduct money, and a service position is also to serve the people.

The key is that you can't afford to lose face!

Therefore, the current focus is whether the quality of this furnace is qualified after the oriented silicon steel sprayed with Jianggang's self-developed coating? The comparison data is that the hot-rolled oriented silicon steel sprayed with Xinnitin coating.

Based on the analysis of sampling data and real-time monitoring data of instruments, Zhao Qingshan felt that their chances of winning should be more than seven points, with a guaranteed eight points, and no top-up.

However, just like Laojun's industrial case of refining Sun Monkey, Sun Monkey is not released, and ghosts know whether he is a qualified monkey or a inferior monkey, everything is unknown.
