Meng Shuizhi, the head of the section, took the initiative to take responsibility, and Director Qin was tolerant and generous to express his understanding: "People are not sages, who can do nothing?" Lao Meng does not have to blame the worker brothers too much, 10 tons of scrap steel can continue to play a role as scrap raw materials, make the best use of it, do not because of occasional carelessness, and hit the production enthusiasm of front-line workers. ”

Meng Shuizhi held Director Qin's hand tightly: "What Director Qin said is so right, long live understanding! I promise, we will never make the same mistake a second time!"

"Director Ye, Xiao Zhao, colleagues, you have maintained close cooperation with the Second Steel, refined the military steel, and lived up to the trust of the people's soldiers. ”

After Director Qin finished explaining, he left.

Ye Guoguo really has a bunch of at hand, he is in charge of two research rooms, more than 100 people, subordinate staff room application, evaluation of professional titles, routine personnel promotions that are not within the scope of this cadre recruitment, etc., he takes these chores to heart and can't throw them away.

However, Director Qin's instructions could not be left unfulfilled, and Ye Guoli stayed in the steelmaking workshop to supervise the smelting of 945 steel.

Molten iron and scrap steel are sent to the steelmaking furnace, and the 945 steel smelting of the new furnace is being smelted.

Meng Shuizhi is not suspicious of employing people, even if Weizi made mistakes, Meng Shuizhi still insisted on letting Weizi inject ingots.

Wei Zi, who was ashamed and brave, operated as fiercely as a tiger, and Meng Shuizhi monitored Wei Zi's ingot injection operation throughout the process.

The oxygen pressure and carbon temperature of the 945 molten steel in this furnace remained stable, and the data of sampling and testing were not abnormal.

Ye Guoli asked, "Xiao Zhao, how do you feel?"

Zhao Qingshan replied: "Feel good, let's go to RH refining." ”

The 945 molten steel is initially refined, discharged into the ladle car and transported to the RH equipment.

Off-furnace refining is to transfer the molten steel from the converter or electric furnace to another reaction vessel for refining, also known as secondary refining.

RH vacuum refining technology was produced in the late 50s and dominated off-furnace refining.

Under the condition of vacuum and inert gas, 945 molten steel is deeply decarburized, deoxidized, de-inclusions and denatured inclusions, adjusted the composition, and controlled the temperature of the molten steel.

The only RH equipment used by JISCO was the RH-OB method, which first appeared in 1972 and was successfully developed and put into industrial production by Nippon Steel, and JSC obtained the right to use its patented technology.

The RH equipment put into production by Baosteel in November 1985 also uses the RH-OB method, and the technical routes of the two good brothers are highly similar.

More advanced than the RH-OB method is the RH-IJ method, and the inventor is Professor Xu Kuangdi, a well-known steel expert in China.

In 1982, Professor Xu, then deputy director of the Department of Metallurgical Engineering of Shanghai University of Technology, published a paper on the RH-IJ method, which constructed a complete set of refining theory of the RH-IJ method.

How to translate the theoretical research results of RH-IJ into industrial application technology?

China's steel mills did not have strong enough industrial transformation strength five years ago.

Nippon Steel began industrial experiments with the RH-IJ method in 1985 through rational and legal business transactions, and at the end of 1986, Nippon Steel began full-scale industrial production at the Nagoya Plant of the same company.

"The decarburization speed of RH-OB is fast, but there are many disadvantages, such as low efficiency, serious splashing, and the RH vacuum chamber is prone to nodulation, etc., in contrast, the Xu's RH-IJ method invented by President Xu is more efficient and reliable. Ye Guoli stared at the RH furnace monitoring instrument and looked at his watch from time to time.

Professor Xu, who was born in the Anti-Japanese War era, was formerly known as Xu Kangdi, which is the same as Lin Podi.

Professor Xu, who has achieved remarkable results in scientific research, has now been promoted to executive vice president of Shanghai University of Technology, and Ye Guoli is his fan.

"RH-IJ and RH-KTB are very advanced, but our RH equipment can't be changed for a while. Liu Yahui is obviously eager to make achievements, but he always likes to whisper behind others' backs and complain.

"Time is tight, the task is heavy, the risk is high, and you can't complain about Director Bao in terms of technical transformation, he did the right thing. Zhao Qingshan said a fair word for Director Bao.

Most of the operators in the RH operation room are undergraduates and college students, under their precise control, the vacuum pump converts the pressure energy of the steam into kinetic energy, the high-speed steam is mixed with the furnace gas, the two gas streams carry out a violent energy exchange, the pumped gas continues to mix with the high-speed steam, while gradually compressing, the speed reaches the speed of sound, and the pressure continues to rise.

All the chemical reactions take place in the vacuum chamber, the top gun blows oxygen to force decarburization to 20ppm, the chemical reaction heat of aluminum alloy is added to significantly increase the temperature of the molten steel, but the reaction products of the aluminum may contaminate the molten steel, and the exquisite micro-operation of the operator makes the temperature range not exceed 20 degrees Celsius, thus ensuring the refining quality of the molten steel.

The vertical belt conveyor loads various metallurgical materials into the high-level silo, and the wire feeder feeds various wires into the ladle, argon is fully stirred, oxygen and sulfur are further removed, and the fine-tuning of the alloy composition can be reduced to a trace of less than 0.001%.

"Everything went well, we can feed the boron silk. Ye Guoguo gave an order, and he had been squatting in the second steel for a whole day.

Ye Guoguo frequently looks at his watch, looking at his watch every 10 minutes on average.

His Shanghai watch is a good watch, shining with gold and dazzling.

Ye Guoguo is by no means showing off his wealth, he keeps looking at his watch because he has something in his heart.

Zhao Qingshan said: "Director Ye, go back to the institute first, this furnace steel continuous casting line will be late at night." ”

"To tell you the truth, there are several important documents in the office that I need to sign. Then you guys continue to follow up, and I'll go back to work on the paperwork. Everyone, you should eat, eat, rest, and fight, you should combine work and rest, and report to me in time if there is any situation. Ye Guoguo strode out of the operation room and went to get busy with his administrative business.

Liu Yahui said with deep feelings: "Director Ye is really busy, and he is really tired of being a leader. ”

Liang Minfang asked: "Didn't you also apply for the cadre position, aren't you afraid of being tired?"

"If you are afraid of hardship and tiredness, you should not be a leading cadre?" Liu Yahui asked rhetorically, and said: "Liang Gong and Zhang Gong, the three of us are the same year, and we are all 30 years old this year, even if the Organization Department does not carry out this cadre recruitment, we should also be promoted to section chief." If you don't give the post of section chief, you should also give us parentheses--- is the treatment at the department level, isn't it?"

"Are you a ghost, want to be an official and want to go crazy?" Liang Minfang scoffed, she said: "People's energy is limited, and it is difficult to concentrate on technical research when you become an official. ”

"Liang Gong, you are noble and majestic, I am a layman. Leave the two to guard, and the other two go to eat. ”

The four engineers of the Steel Research Institute are also quite hard, the operation room has changed shifts, and the four engineers have no one to change, so they can only take turns to go to dinner.

The brother in the operation room who had just changed shifts said, "We are guarding here, and the four of you will go to dinner together." ”

"I'm not hungry, Liang Gong, Zhang Gong, Liu Gong, you go eat first. Zhao Qingshan patted the shoulder of the brother in the operation room and reminded: "Brother, hurry up and feed the boron silk." ”
