The communication between engineers is simple and direct, the technology is paramount, and the data speaks.

Zhao Qingshan continued: "These foreign researchers have made a remarkable data to reduce the burning loss rate by 85% under laboratory conditions, and of course, they themselves have said that it is the most ideal situation to reduce it to 50% in industrial production. ”

"Therefore, the purpose of our research is to develop a new type of magnesium oxide-chromium trioxide material with the No. 3 furnace of the hot rolling mill as the improvement point, challenge the theoretical extreme value of reducing the burning loss rate by 50% in industrial production, and increase the life of the No. 3 furnace, and burn 5000 tons of oriented silicon steel to repair the furnace once to burn 6000~6200 tons to repair the furnace. ”

"The technical solution is to use industrial magnesia and chromium trioxide as the main raw materials, add some necessary additives, and ensure the rheological properties and thermophysical properties of the new protective coating. ”

"Industrial magnesia and chromium trioxide are simple and easy to obtain, and there are many Jianggang coking plants and refractory plants, which are inexhaustible. So what are the necessary additives, and what are the specific chemical formula components? This has to be experimented, and the required experimental materials are shown in Table 11. ”

"The two are most concerned about economic benefits, which is easy to calculate, based on 50%, 6,000 tons, oriented silicon steel prices, and single furnace repair costs, if the project goal is achieved, it can create economic benefits of 3.085 million yuan per year. ”

"The research fund I need is 32,000 yuan, and this investment is definitely not a loss, so please ask Ma Gong to approve the project. ”

Zhao Qingshan confidently made a statement, compared with the development of new steel grades, this process subject has less investment, quick results, and can produce results within the year.

Ma Hanxing stared at Table 11, quickly turned to Table 12, and then returned to Table 11 again, he interrogated: "The experimental materials you need are industrial magnesia, chromium trioxide, aluminum oxide, ferric oxide, phosphorus pentoxide, zirconium dioxide, zinc oxide, boron trioxide, and antimony pentasulfide...... There are as many as 99 kinds. ”

"I don't see any use for some of the material, and you don't write anything about it in your mission book. Let's talk about this antimony pentasulfide, what role does antimony play in the coating reaction? Or is it just a lot of experiments under the violent elimination method to try and make mistakes? If it is a violent elimination method, how can the experimental funds of more than 30,000 yuan be enough? So Xiao Zhao, please give me a reasonable explanation. ”

The project we are doing has a certain innovative nature, and some technical links have to cross the river by feeling the stones.

If I write the task of the project like the result paper, then I am not the god of the unpredictable prophet?

Zhao Qingshan explained that Ma Hanxing did not veto or approve it.

Ma Hanxing said that he needed a few days to check the task book, Xiao Zhao, what should you do, you will rest tomorrow, and you will go home to see your parents.

So Xiao Zhao went back, he took a bus along Linjiang Road to Hanyangmen Wharf, took a ferry across the river to reach the Han Pass, took a car in Hankou to go north, the car and boat tossed each other for a whole day, and he finally returned to Huangpi County.

Huangpi County is now managed by Jiangcheng, Zhao Qingshan's home is in Gouzi Township, Huangpi County, where the economy is underdeveloped, a very small number of people got rich first, and most people are still poor, but much better than before.

Without the Communist Party, there would be no New China, millions of serfs turned over and became masters, and the grain stored by the most ordinary peasant families in Gouzi Township now exceeds that of Huang Bajin's father --- the landlord before liberation.

"Mother, it's okay. Zhao Qingshan came back with two bottles of Guozhen, and he personally demonstrated how to drink Guozhen, scooping a spoonful, putting some sugar, boiling water, and stirring a hazi, which was quite delicious.

"It's expensive. The old lady squinted, smashed her mouth, and slowly tasted the fruit of her son's bubble, which was indeed quite delicious.

"Old lady, you collect the land in the house alone, brother?" Zhao Qingshan went home mainly to see the old mother, and by the way, confirm the exact area of the family's fields.

"My brother is busy, doing big things and making a lot of money. ”

"He's still going to get a fishpond?"

"When I first started, I was very busy. ”

It is common for men to work outside the home and for women to work in the countryside. China's hukou policy is that children follow their mothers, and although some gay men have become county leaders, their children are still peasant villagers.

Zhao Qingshan's old man is a small cadre in the county, Zhao Qingshan works in the distant Jianggang, Zhao Qingshan's eldest brother contracts fish ponds for breeding, and the old lady guards the feng shui treasure land at the door of her home.

In the vast countryside of China, having more sons is good for fighting. Zhao Qingshan has a career in the city, and the important task of protecting his family from being bullied is entrusted to his eldest brother Zhao Qingfeng.

"Brother, my mother will work hard for you to take care of me, I haven't farmed and harvested grain for a long time, my hands are born, my face is born, and the cows don't listen to me, and I still arch Lao Tzu!"

"Xiaoshan, you are the only college student in our Gouzi Township, college students want to have a big career, you can do a career in Jianggang with peace of mind, there is me in the house, and it will be fine." The fish pond contracted by Zhao Qingfeng is not far away, he carried a big bag of Huang Pi meat cake and Huang Pi meatballs, and asked Zhao Qingshan to bring them back to Jianggang to eat, and instructed Zhao Qingshan to give half of them to leaders and colleagues, meaning that they should have a good relationship and not offend people. We Huang Piyan must be able to be a person in the city before he can come out of the hall.

Zhao Qingshan stayed in Huang Pi's hometown for one night and returned to Jianggang the next day.

The house he divided into no refrigerator, no washing machine, no right-angle remote control color TV, only an energetic and strong man.

Zhao Qingshan gave the meat cakes and meatballs to the group of people who got rich first who had refrigerators at home.

"Xiao Zhao, you are too polite, then I am not welcome. ”

Ma Hanxing laughed at Huang Pi's specialty, one yard to one yard, the specialty is a specialty, and the subject is the subject.

"Going back to the No. 3 furnace project, this project is time-consuming and labor-intensive, and we have limited manpower, so my idea is that the three of us should finish the D340 project as soon as possible. If the project that is being worked on has not yet come to fruition, the institute will not approve us to start a new project. ”

Ma Hanxing is the person in charge of the D340 research group, Zhou Tienan is the person in charge, and Zhao Qingshan is the assistant.

Ma Hanxing is the corresponding author, Zhou Tienan is the first author, and Zhao Qingshan is the second author.

D340 only has the last furnace left, and the pass rate of the first 19 furnaces is 95%, the overall situation has been decided, and the rest is a beginning and an end.

Ma Hanxing, Zhou Tienan, and Zhao Qingshan came to the silicon steel plant, along with Nippon Steel technical representatives and his translators.

The last furnace of D340 hot-rolled silicon steel coil is uncoiled by a double-head uncoiler, sent to the cutting machine to remove the plate head, and then sent to the HiB furnace for normalization annealing. It took a long time to prepare the raw materials for cold rolling, and after a single operation, the D340 was finally sent to the Sendzimir machine for rolling.

D340 is a high-grade electrical steel that can be used to make the core components of electric motors, generators, transformers.

After inspection, the content of Si, Mn, Al, S and other elements in the last furnace of D340 trial silicon steel sheet is OK, the magnetic properties have reached the original brand standard, and the overall pass rate of 20 furnaces D340 exceeds 95%.

The Japanese technical representative stretched out his friendly palm and shook hands with Ma Hanxing.

The interpreter happily translated the congratulatory speech of the Japanese representative into Chinese: "Congratulations, you have done it! The performance indicators of D340 have reached the Japanese standard, and the patent transfer contract has been announced, and the cooperation is happy!"

Ma Hanxing's face was expressionless, and he symbolically shook hands with the Japanese representatives and saw off the guests.

"I feel a little sick in my heart. Ma Hanxing said to the two younger brothers.

"So do we. ”

"When the great comrade inspected Jianggang, he gave clear instructions: We must not always follow the butts of others, we must strive to catch up with and surpass, and achieve the world's advanced level. Do you two know what the direction of our efforts is? We want to develop better silicon steel, sell it back to Dongying, and realize the anti-assignment of patents! One day, we will say to the devils, "Congratulations, you have succeeded, you have reached the standards of Jianggang, and you are happy to cooperate!" Hu Deyi and Hu Gong have set an example in weathering steel, so learn from Hu Gong. ”

Zhou Tienan asked: "Ma Gong, then our next topic is to make better silicon steel, or?"

"Hu Gong's weathering steel research group has more than 20 technical backbones, and it took five years to produce results. Research and development of new oriented silicon steel, just the three of us?"

Ma Hanxing's instructions were to write a report on the completion of the project as soon as possible, and report it to the office for acceptance, and at the same time start to write a paper, let Xiao Zhao evaluate an assistant engineer, and then at the same time carry out the "Solution for Serious Burning Loss of Oriented Silicon Steel in the No. 3 Heating Furnace of the Hot Rolling Mill", and the topic of the newspaper will be opened. The topic of the No. 3 furnace is still a head, we are bigger and stronger step by step, recruiting troops, and creating brilliance.
