Chapter 104, Oxygen Converter

"Boss, I'll take your "Wangzi" to work today." At the dinner table, Xu Damao finished his meal in twos and ran out without saying a word.

Then He Yuzhu also hurriedly finished his meal and ran out.

Seeing these two people, Jiang Yan was a little speechless.

At this time, Shi Shi, who was also eating at the dining table, said: "Boss, I will ride your bicycle to work today."

Jiang Yan nodded after hearing Shi Shi's words.

Xu Damao and He Yuzhu were fighting over who should sit in the funnel, and they were so furious that neither would let the other go.

Jiang Yan, who was about to ride a bicycle, saw this situation and shouted directly: "Zhuzi rides on the funnel, Damao sits on the back."

"Boss, why can the pillar sit on the funnel?"

Hearing Xu Damao's words, Jiang Yan said helplessly. "He has a big build, and it's hard to sit in the back."

Hearing Jiang Yan's words, Xu Damao looked at himself and then at the car seat. He could only sit helplessly behind Jiang Yan and Xiao Liuzi.

After everyone got on the motorcycle, Jiang Yan stepped on the accelerator, started the motorcycle, and rode towards the steel rolling mill at full speed.

In the blink of an eye, Jiang Yan had already returned to the steel rolling mill for two days. At this time, the floor of Jiang Yan's office was scattered with many pieces of papyrus filled with words.

After finally finishing the calculation, Jiang Yan rubbed his aching wrist and took a look at the formula and process flow he had written. He nodded with satisfaction. It took almost a week to finally get it done.

I still put the data compiled during the day on the space computer every night for calculation, and it still took so long.

If I had used these simple calculation tools in the department, I probably wouldn't have been able to finish it in a month or two.

Seeing these crude calculation tools, Jiang Yan couldn't help but admire the seniors who used these tools to grow mushroom clouds.

Jiang Yan stood up and put the compiled information into the safe.

After putting it away, Jiang Yan picked up the phone and dialed the number of the guard room on the second floor, asking the guard to notify the cleaning staff to clean up his room and request that all papers with writing on them be destroyed in accordance with regulations.

After putting down the phone, Jiang Yan left the office and walked directly to the fifth workshop.

The fifth and sixth workshops of the steel rolling mill are also called steel-making workshops. From the literal meaning, it should be understood that the main function of these two workshops is to make steel.

Most of the steel required for the production of steel rolling mills is produced by these two workshops.

"Gong Jiang, why are you free to come to our workshop today?"

In the steel rolling mill, Jiang Yan is almost always called section chief on formal occasions, but workers prefer to call Jiang Yan "Jiang Gong."

"Why, Director Guo, I think you are being picky! You are blaming me for not talking to our steelmaking workshop."

Director Guo Minghui, who was embarrassed by Jiang Yan's words, scratched his head and smiled at Jiang Yan.

Director Guo, who is already very dark, makes his teeth really white in this smile.

"This matter is also my fault. I should have come to our steelmaking workshop earlier to have a look. I apologize to my brothers here."

Jiang Yan's apology made Director Guo a little embarrassed.

So he directly pulled Jiang Yan into the workshop, introducing the situation in the workshop as he walked.

"Our workshops five and six are the two workshops with the most workers in the whole factory. Compared to the other workshops, the work in our workshop is relatively light."

"We have three open-hearth furnaces for steelmaking in our fifth workshop, two of which are 300T, and the other one is 500T. In our entire Sijiu City, these are the only two 500T open-hearth furnaces."

"In addition to one 300T and two 200T open-hearth furnaces in Workshop 6, our workshop can produce up to 20W tons of steel per year. The steel produced can not only satisfy our steel rolling mill, but can also be supplied to some enterprises."

As he spoke, Jiang Yan could feel Guo Minghui's slowly growing sense of pride.

Jiang Yan nodded while listening. As soon as he entered the workshop, a wave of heat swept over him. The workers working in the workshop were wearing relatively simple clothes.

Every time Jiang Yan passed by a worker, the workers greeted Jiang Yan warmly.

They also saw clearly what Jiang Yan did from the moment he entered the factory, and knew that Jiang Yan was a capable person. Naturally, they became much more enthusiastic.

After Jiang Yan finished visiting the two workshops, he returned to his office, looked at his safe and sighed.

It seems that my share of 7075 aluminum alloy will be taken out later. The top priority now is to increase the production of steel and update the equipment.

Jiang Yan knew that in 1955, the country's steel output was only 2.85 million tons. At that time, the country's annual steel output was not comparable to that of a large steel plant in Europe and the United States.

At that time, the country's population was almost 615 million, and the per capita steel production increased to 4.64 kilograms. In this year, India's per capita steel production was only 4.35 kilograms. Although it exceeded India, North Korea's population in 1955 was only 9.07 million, but it created 13.7

The crude steel output of 10,000 tons is 15.1 kilograms per capita, which is more than 3.2 times that of China.

Construction is going on all over the country, and it cannot be done without steel. Steel is the backbone of a country.

When Jiang Yan visited two steel-making workshops just now, he noticed that the open-hearth furnaces in these two workshops had been used for a long time. The latest open-hearth furnace was the equipment of the Little Devil more than ten years ago.

It takes about eight hours to produce one furnace of steel, and the production efficiency is too low.

In the later stage, I will have to do a lot of experiments, and I urgently need an experimental workshop. I can't go to the steelmaking workshop or other workshops to collaborate for every experiment. This is too troublesome.

Jiang Yan laid a new piece of white paper on the drawing board and began to write and draw on it.

The steelmaking furnace designed by Jiang Yan is called oxygen side-blown converter steelmaking. Air or oxygen is blown into the molten pool from the side of the converter wall to oxidize carbon, silicon, manganese, phosphorus and other elements in the iron water, and the heat is increased.

A converter steelmaking method that smelts molten steel at the molten pool temperature.

Jiang Yan remembered that alkaline air side-blown converter steelmaking was a steelmaking method that was successfully tested after liberation and developed rapidly during the mass movement to promote steel in 1958. It is well adapted to my country's resource conditions. In line with the needs of local industrial and agricultural development at that time, it has made certain contributions to the development and improvement of the layout of my country's steel industry for more than 20 years.

The factory where Jiang Yan worked previously had a 30T oxygen side-blown converter steelmaking furnace.

In his own time, this kind of steel-making furnace has been replaced by more advanced steel-making furnaces, but now the oxygen converter steel-making furnace is the mainstream steel-making method in the world.

Compared with the current open-hearth furnace, this method consumes less fuel and has much higher productivity. More importantly, the cost of manufacturing a converter is only about 60% of that of an open-hearth furnace.

The furnace consists of a converter body, a tilting system, an oxygen lance and an oxygen supply system. It can be produced according to the current technological level.

Jiang Yan had dismantled and repaired the company's oxygen side-blown converter a lot before, and he was very familiar with the various structures inside.

Therefore, Jiang Yan painted very quickly, with almost no pause. After a while, Jiang Yan was surrounded by piles of design drawings.

After stopping to make the last stroke, Jiang Yan collected all the drawings and then wrote a detailed introduction to the oxygen side-blown converter.

After finishing writing, Jiang Yan went directly to the factory director's office.
