"Xiao Zhao, you really hid something. Ma Hanxing's eyes burst out with sharp essence again, and only a second later, the essence turned into the encouragement and care of the leader: "Hide or not, it doesn't matter, the important thing is that we have made a breakthrough in laboratory conditions, if the industrial production has also broken through the theoretical extreme, Xiao Zhao, you are the biggest hero." Xiao Zhao, you have worked hard, you must pay attention to your body, you hurry up and go home to sleep, you are allowed to take a day off, see you tomorrow. ”

"Okay, then I'll go, see you tomorrow. ”

Zhao Qingshan said goodbye and left, and needed to leave a day for Ma Hanxing and Zhou Tienan to digest and absorb this version of the freshly baked experimental data.

In order to verify that the experimental data was not made up blindly, Ma Hanxing and Zhou Tienan redid it step by step according to Zhao Qingshan's experimental records, until late at night.

The results of the experiments of the two were consistent with Zhao Qingshan's, and the experiments under such laboratory conditions were repeated for a week.

Robust laboratory data provide convincing evidence for industrial production.

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

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and gentle oven has become a huge and wild heating furnace, and the pocket-sized experimental silicon steel slab has been replaced by a mass-produced silicon steel slab weighing tens of tons.

Precise control under laboratory conditions is not 100% reducible in industrial production, so the data under laboratory conditions are often exaggerated, and there are certain differences in industrial production.

It is industrial production that creates benefits, and the laboratories in the enterprise serve the benefits and serve industrial production.

After seeing the experimental data, Director Ye Guoguo's first reaction was surprise: "You three stinkers have at least surpassed half of Zhuge Liang." ”

Ma Hanxing patted Zhao Qingshan on the back: "Xiao Zhao is an outstanding talent, and his contribution is the highest. ”

"It's too early for you to say that, I'm going to put a big question mark. Contribution is linked to industrial production, and if you succeed in industrial production, you are really successful. I immediately made a phone call with Mr. Wu, the director of the hot rolling mill, and arranged for the test of the No. 3 furnace to mass-produce silicon billets as soon as possible. Ye Guoguo has arranged this, and the experimental transfer to production is a major event, which requires the consent and cooperation of the production workshop.

The task book has already been sent to the hot rolling mill, and Director Wu said that there is no problem.

When everything is ready, the next step is to choose an auspicious day for the zodiac.

Because of the inherent characteristics of oriented silicon steel, liquid slag is continuously produced during the firing process, which accumulates at the bottom of the furnace, and when the liquid slag accumulates to 300mm, the grate must be stopped and discharged, otherwise the liquid slag will overflow the column embankment and flow into the water seal tank at the bottom of the furnace to cause an explosion.

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

At the same time, the refractory materials of the beams, columns, and embankments at the bottom of the No. 3 furnace have also suffered serious erosion and need to be replaced regularly.

Safe production, safety first, no safety, how to talk about production.

The work of repairing the furnace is related to human life and national property, and the current situation of the No. 3 furnace of the hot rolling mill is to fire 5,000 tons of oriented silicon steel every month, then stop the furnace for 15 days to repair the furnace, and then resume production, and so on.

At present, the No. 3 furnace is under repair, and it is expected to resume production on October 25 to fire the next batch of 5,000 tons of oriented silicon steel.

Early in the morning of October 25, Ma Hanxing, Zhao Qingshan, and Zhou Tienan came to the hot rolling mill.

A large group of people in the hot rolling mill are waiting here, they are Director Wu, workshop director, equipment section chief, Zhang Gong, several section leaders/workshop technicians.

"Three experts, I can wait for you!" Director Wu shook hands with the three experts of the Iron and Steel Research Institute one by one, gossiped little, and went straight to the topic, and he immediately ordered to open the furnace and send the board to spray paint.

The repaired No. 3 furnace started normally, and the cleaned silicon steel slab was hoisted on the roller table by a 40-ton half-gantry crane, sent to the entrance of the No. 3 furnace, and pushed onto the material rack with a steel pusher.

When heated to 300 degrees, the sprayer sprays an aerosol coating on the surface of the silicon steel slab.

The spraying device in the laboratory is a small and short-gun earth cannon, and the industrial spraying machine of the No. 3 furnace is a real knife and a long-barreled cannon.

The liquid paint in the paint tank was replaced by Nippon Steel's silicon-silicon carbide system, which was independently developed by the steel research institute's laboratory, with magnesium oxide-chromium trioxide system.

This furnace is oriented to silicon steel heated to 1320 degrees Celsius and needs to be kept warm for 5 hours.

"Sample, sample!"

The three experts of the Iron and Steel Research Institute shouted, and the director of the factory Wu instructed the workers in front of the furnace to take samples of silicon steel from the No. 3 furnace.

These are industrially produced samples, some of which can be done in the hot rolling mill, and some of which need to be taken back to the steel research institute for further analysis.

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

Zhao Qingshan replied: "After spraying our self-developed new coating, the second layer with the main crystal phase is a solid solution, and it also contains a small amount of mafic olivine phase with a high melting point, so we can only get this preliminary conclusion." ”

"Zhao Gong, you just tell me if there is a problem or not, it's okay. "Director Wu is afraid of problems, but he is eager to solve another problem, and people are greedy.

"I can only say that the protective effect has been formed, and whether the silicon steel in this furnace will be smelted and scrapped will be known in a few hours. "Zhao Qingshan is still a little nervous, this furnace of silicon steel dozens of tons, first of all, to ensure that the quality of the new paint is not affected, let's study whether the furnace has become more durable.

"There must be no quality problems, no problems. Director Wu went around the three experts of the Steel Research Institute, and his mind was heavy. He didn't have a house in Jianggang, so he took the initiative to give up the quota to the workers. He ran a monthly ticket every day, went back and forth between Hankou and Gangcheng, came early, left late, and Director Wu, who couldn't sleep for a few hours, broke his heart for the hot rolling mill.

The furnace has become stronger, but the silicon steel has become weaker, which is to put the cart before the horse, and it is absolutely unacceptable.

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

It means that Zhao Qingshan's efforts during this period of time are all in vain.

Not only in vain, but also in responsibility.

If the workers smelt scrap steel, they will have to deduct their wages and bonuses, and even more seriously, they will be transferred from the front-line production posts and sent to the bathhouse to collect tickets.

It's the same when engineers make mistakes.

It doesn't matter if the money is deducted, the service position is also to serve the people.

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

Therefore, the current focus of attention is whether the quality of the oriented silicon steel sprayed with Jianggang's self-developed paint is qualified?

From the analysis of sampling data and real-time monitoring data of the instrument, Zhao Qingshan feels that their chances of winning should exceed seven points, and the guarantee is eight points, and there is no upper limit.

However, just like the industrial case of Lao Jun refining Sun Monkey, Sun Monkey is not baked, and the ghost knows whether he is a qualified monkey or a defective monkey, everything is unknown.
