Siheyuan: Craftsmen of a Great Country

Chapter 322 Things must turn against each other when they reach their extremes
“There are many blowing combination methods, but we use top blowing of more than 99.5% pure oxygen and bottom blowing of mixed inert gas to make steel.”

"Bottom blowing inert gas mainly has two functions, stirring the molten pool and controlling the reaction speed. In the early stage, nitrogen is mainly used. In the middle stage, nitrogen blowing must be stopped to avoid bubbling and affecting the quality of the steel."

"This is the slag splashing furnace protection, which can effectively prevent the slag from splashing. Otherwise, it would be necessary to build the furnace and repair it after one furnace of steel training, which wastes time and materials and affects efficiency."

"The refractory lining bricks at the furnace mouth are extremely easy to damage. If the furnace mouth deforms, it is inconvenient to maintain and repair. Therefore, water-cooling components must be installed at the furnace mouth to slow down the damage and deformation of the furnace mouth so that it can synchronize with the life of the furnace lining bricks."

When Su Changming directed people to start building the converter according to the schematic diagram of the 200-ton converter construction, Jiang Chen also began to teach Shangguan Wan'er with the pictures.

The structure of the converter, the function of each part, precautions, possible problems and how to deal with them.
As long as he can think of it, there is no reservation.

After all, he is just a disciple, and he has a strong memory, which deserves to be cultivated.

If there is one more person to share the burden with, he will have a lot less things to do in the future.

After she masters converter construction, she can teach converter steelmaking knowledge.

In order to provide better explanation and guidance, the two of them looked at the drawings.

It’s just that Jiang Chen didn’t pay attention.

Even she herself didn't know that because she had deliberately suppressed her desires for a long time, her body was already much more sensitive than that of an ordinary girl.

So just like the spring, excessive suppression brought backlash to him.

Unconsciously, the two of them were so noisy that they almost bumped into each other.

It's just that because I haven't had much contact with the opposite sex, I haven't shown it yet.

He stood up, lit a cigarette, and walked towards Su Changming and others who were building the foundation of the furnace.

Their bodies are even closer to each other.

Shangguan Wan'er listened carefully and watched carefully.

She secretly took a breath: "Wan'er, you watch first while I smoke a cigarette."

The man is warmer than the goddess, and with his sensitive body, she feels it even more intensely.

Li Xiang teaches in a responsible and detailed manner.

It was the first time that I was so close to a member of the opposite sex. It was Jiang Chen who had a charm bonus and was very attractive to the opposite sex.

The voice trembled slightly.

Jiang Chen could feel the heat on her body, and she must also be able to feel the heat on Jiang Chen's body.

Obviously I had just fought with the two women last night, but this was a normal close relationship, and yet...
Shangguan Wan'er didn't even raise her head: "Okay!"

So I have always been very depressed about love.

When Jiang Chen walked away, Shangguan Wan'er's face instantly turned red.

No one paid attention at first, but it wasn't until Jiang Chen felt the warmth coming from his body that he realized what he was doing.

But it happens that if you read more, you will know more.

She comes from a scholarly family, and has been taught to be gentle, quiet, and as gentle as jade since she was a child.

I don't know if it's due to the change in the system or something else, but Jiang Chen feels that his needs are relatively strong.

Her mind had long been confused and she even started thinking wildly.

The master has always been great.

Otherwise, how could Liu Yue and Luo Xue, two beauties, be so harmonious, and the two girls were so moisturized that they could drip with water?
I don’t know what it would be like if it were me.

Fortunately, Jiang Chen took the initiative to leave, thus avoiding the embarrassment between the two of them.

Knowing that Jiang Chen left, Shangguan Wan'er snorted and sighed:
"Shangguan Wan'er, Shangguan Wan'er, what are you thinking about? He is your master, your leader, and he has a partner."

"You come from a scholarly family and have read a lot of poetry and books. You must restrain yourself."

But there was a little devil saying faintly: "Isn't this more exciting?"

Jiang Chen didn't have the skill of mind reading, so he naturally didn't know what Shangguan Wan'er was thinking.

He came to Su Changming: "Aren't you going to build some tracks?" Su Changming was stunned: "What tracks?"

Jiang Chen pointed to the open-hearth furnace behind him: "The molten iron refined from the open-hearth furnace will be directly transported to the converter via rails, and then lifted up by a motor."

"Isn't this more efficient than pushing it with a trolley and has a larger load capacity?"

Su Changming slapped his head: "Hey, it's all habitual thinking."

"Because there are no tracks in front of the converter in the laboratory, I didn't think about it. Simply laying a few rails would be very convenient."

"Okay, I will discuss this idea with Factory Director Xie later and ask him to find someone to adjust the plan and lay the rails."

Jiang Chen nodded: "This is a 200-ton converter, which is many times larger than the converter in the laboratory, so you must be firm on the foundation of the furnace."

"The theoretical carrying capacity must be at least twice the calculated weight. Because I feel that after this converter is built, we may have to overload steelmaking."

Su Changming chuckled: "Isn't this putting production first?"

"But don't worry, we will definitely try to overload appropriately under the premise of safety, and we will not mess around."

Jiang Chen said: "How you use it is your business."

"I just want to say, safety first, otherwise an accident will only seriously affect your production."

Su Changming said: "Director Jiang, don't worry, our factory has been making steel for some years, and we have always attached great importance to safety issues."

Jiang Chen said no more: "That's good."

Every factory has its own working style and difficulties, and it's hard for him to impose anything.

Fortunately, when he formulated the parameters of the 200-ton converter, he designed it based on the load capacity of 400 tons.

As long as one furnace does not exceed this output and the quality is controlled during construction, it is absolutely safe.

Jiang Chenyou carefully observed the construction situation.

I found that Su Changming didn't give any discounts at all. No matter the dosage or size, the construction was strictly in accordance with the requirements.

I feel relieved.

This Su Changming is relatively reliable.

He took out a cigarette and threw one to Su Changming, then lit another one himself: "Su Gong, what are your plans for the future?"

Su Changming was stunned: "What are your plans?"

Jiang Chen said: "After the construction of the converter at Shijingshan Steelmaking Plant is completed, the only thing left is steelmaking."

"I think it's a bit wasteful for you to focus on steelmaking. What about you, consider joining our laboratory?"

He had said this to Su Changming before.

But in the end, Su Changming did not give a specific answer. He probably gave up after careful consideration.

Su Changming said: "I have considered this matter before, and I also wanted to join the laboratory at one time, where I can not only make more money, but also generate the greatest value."

"But in the end, I gave up. Because this steelmaking plant is like my home. I have invested so much emotion in it that I really couldn't bear to leave."

"And the current factory director and deputy director have always taken good care of me, and I don't want to turn my back on them."

The words were very clear, and Jiang Chen couldn't persuade him anymore: "As one of the participants in the whole process of converter steelmaking, would it be okay for you to help us promote the steelmaking method?"

Su Changming smiled and said: "Of course there is no problem. If you need it, just tell the factory and I will be at your disposal during this time."

Jiang Chen smiled and said: "It's not that urgent. The documents from above have not been issued yet, and the oxygen concentrator has not been purchased yet."

"We'll wait until the converter of Shijingshan Steelmaking Plant is successfully put into operation."

Su Changming nodded: "Okay, when you need it, just tell me in advance, so I can make arrangements in advance."

Jiang Chen nodded: "Don't worry, I won't be polite to you."

"Even the comrades who are participating in the construction with you and the converter steelmaking promotion team will be seconded."
