Feng Yuheng was quite interested in walking sideways, but now she had to face a very troublesome problem: teaching Xuan Tianming to read simplified Chinese characters.
She told Xuan Tianming: "I write like this entirely because I am lazy. I want to write less strokes. Anyway, I just know what it means."
Xuan Tianming didn't believe this and simply said: "You can tell me directly that this is Persian."
She spread her hands: "Although I really want to say this, in fact, it is really not a Persian word. If you insist on saying it higher, you will have to find out sooner or later."
Xuan Tianming wanted to say that there would be a lot of things that you would have to do in the future, but he still didn't want to expose it. Under the guidance of Feng Yuheng, he began to read "Feng's Steelmaking Strategy" written in simplified Chinese.
The so-called "Feng's Steelmaking Strategy" is actually the steelmaking steps written by Feng Yuheng himself. From slag making and slag extraction, to the final silicon addition, endpoint control, and steel tapping, there are nineteen steps in total. Each step has detailed instructions.
Explanation and explanation. And for some problems that cannot be solved in today's era, she has also done analysis herself, found replacement methods, and explained them in detail. However, this replacement method has not been tested, and it is not known yet.
Whether they can succeed or not is one of the biggest difficulties for them in making steel.
Xuan Tianming's receptive ability is considered fast. Feng Yuheng told him some rules for reading simplified Chinese characters and guided him to read a few more. After that, he was able to figure it out on his own, but there were some too professional predicates.
Feng Yuheng needs to explain.
An hour later, he finally put down the guide and said to Feng Yuheng: "Steelmaking is not easy. After reading this, I am more convinced of its difficulty. I can't guarantee success, but at least we can try.
If it doesn’t work once, try it twice; if it doesn’t work twice, try it twenty times. No matter how long I try, I believe I will succeed, and God won’t be so unkind to me Dashun.”
She nodded and started to tidy up the furnace and said: "This has nothing to do with whether God pities Dashun or not. Although I have never made steel with my own hands, I have watched others make it with my own eyes. It's just that we need to use equipment for some links.
It's impossible, so those alternative methods are where our main experiments are."
Xuan Tianming also became serious, turned his wheelchair, and began to make preparations with Feng Yuheng.
The first step in making steel is to make slag. Compared with the subsequent steps, this is relatively simple. In other words, everything from slag making to slag discharging to bath stirring is simple. It is bottom blowing in an electric furnace. I don’t know about the existing ones.
Whether the huge bellows can be realized? Especially the subsequent melting, oxidation and decarbonization stages are the real test of technology.
The two of them didn't care about their image, and even Xuan Tianming got out of the wheelchair and sat directly on the ground. Feng Yuheng served as the technical director and also took care of the subordinates, and Xuan Tianming was the main operator.
"Slag making is an operation to adjust the composition, alkalinity, viscosity and reactivity of slag in the production of steel and iron. The purpose is to produce metal with the required composition and temperature." She said, and he made one step at a time.
There are strict regulations on the amount, heat and time of each entry into the furnace. He did not dare to carry it with him at all. Unfortunately, after the slag was discharged, Feng Yuheng shook his head: "No, the oxidized slag is not discharged cleanly enough.
It is easy to cause phosphorus reversion." Thinking about it again, "I think everything else is fine, except for the control of time. Although we calculated it carefully, it is still not accurate enough."
Xuan Tianming nodded and said: "Come again."
"Wait." She held his wrist, thought about it again, and simply removed a wall clock from the wall of the space.
Xuan Tianming watched her pull out something so big that it was impossible to stuff it into her sleeves, and her hair stood on end. Fortunately, he had experience when soldiers were poisoned years ago, so he had seen this before.
The girl pulled out a butt from her sleeve. Although she was shocked at the moment, she was not so shocked that she thought Feng Yuheng was a monster. What's more, Xuan Tianming understood that things that are abnormal are monsters, so
If we talk about it, his little wife would have been immersed in the river to worship the gods.
"This thing is called a clock." Feng Yuheng felt guilty and did not dare to explain the origin of the thing. She only talked about the use of the clock in a evasive manner. She told Xuan Tianming: "There are three hands on it, one is called the hour hand, and the other is the hour hand.
The minute hand and the second hand are the same as the sundial we use. However, the sundial is divided into twelve hours, and the clock is divided into twenty-four hours. In other words, one hour on the sundial is equivalent to the clock
's two hours."
She patiently explained the clock to Xuan Tianming, and then said: "This slag removal process takes one hour and forty-five minutes. This time we use the clock to accurately time the time and try again."
"Okay." He nodded, pointed to the twelve o'clock position directly above the clock and said, "The minute hand and banknote hand will start here. This time, there can be no difference at all."
The two of them made all the preparations to start over again, staring at the last two minutes on the clock, second by second. Finally, the ticking second hand passed the last frame and landed at twelve o'clock.
The movements in Xuan Tianming's hands immediately started to work.
Feng Yuheng also stared nervously, following his movements and repeating the steps one by one.
Xuan Tianming remembered very quickly. After the last personal test, he could completely memorize the entire process this time, and his movements were skillful. He looked like a veteran. Even Feng Yuheng had to sigh at this person.
His brain is really powerful and he can do everything well.
Finally, all the processes were completed, and all that was left was to keep time. The last time they were keeping time, they could occasionally say a few words, but this time, even with the clock standing here, the two of them were even more nervous.
There was no communication. I kept staring at the wall clock, not daring to leave at all.
When there was only one minute left, Feng Yuheng reminded in a low voice: "Be ready to start the furnace. You will start the furnace when there are two seconds left."
Xuan Tianming nodded and put his hand on the taboo handle of the furnace.
Finally, the last minute ended, almost at the same moment when the second hand moved towards twelve o'clock, Xuan Tian Ming started the stove and a wave of heat hit his face. When he took out the shovel from inside, he heard Feng Yuheng yelling.
A voice: "It's done!"
As soon as these two words were spoken, even Xuan Tianming became excited. Then he looked at the slag on the shovel and asked Feng Yuheng uncertainly: "Really?"
Feng Yuheng nodded, "Yes! Not only did you succeed, you also created the best slag. With these things, we will have a solid foundation for the next steps. Xuan Tianming, you are really capable!"
She praised her sincerely, and Xuan Tianming also breathed a sigh of relief. This was only the first step. If he had to repeat the first step too many times, his morale would be low.
"We have to continue making slag." Feng Yuheng said: "Although we are just trying to make a piece of steel first, the intermediate steps have to go through countless failures. Every time we fail, the previous materials will be scrapped. Making slag
It is the first step, and we must ensure that the materials for the first step are sufficient so that we can proceed further.”
Xuan Tianming nodded, "Okay, then let's make a few more furnaces. After all, we need to be more skilled." He said, moved the slag of the finished product aside, put it away, opened the furnace again, added materials, and started a new round.
Make slag.
This time he was more proficient than last time, and he had a clearer grasp of the time patterns of clocks. He almost didn't need Feng Yuheng to remind him, and he could operate the entire process by himself.
However, Xuan Tianming did not expect that his scumbag wife who came out this time shook her head: "No, the quality is not as good as last time. It should be that the initial heat was not controlled well and I was a little anxious. You have to be more steady."
"Then come again." Without saying a word, he moved his hands again.
The fourth time, success.
The fifth time, success.
The sixth time, failed.
The seventh time, success.
Feng Yuheng calculated in her mind. At first, she almost succeeded every time and failed once, and sometimes she had to fail twice in a row. Until the sixteenth time Xuan Tian Ming practiced, the success rate began to rise linearly, and the success rate began to rise continuously.
All ten times were excellent products.
Feng Yuheng told him: "You have completely mastered the essence of slag making and slag removal. If the finished product we have now is not as good as the accident, it should be enough to squander. Do these first and continue. If it is not enough, then go back.
repair."
Xuan Tianming nodded, looked at the clock again, and said: "We can't continue, you have to rest." He pointed at the clock and said: "According to the time rules you mentioned, it should be dinner now.
It’s Chen, and it’s dinner on the second day after we enter this place. Hengheng, he hasn’t slept a wink all day and night, and he hasn’t eaten anything.”
"Ah?" She was a little surprised. She was locked in this cave and concentrated on doing one thing, and she couldn't feel the passage of years at all. But she didn't expect that a day and a night had already passed outside. It was okay not to mention it.
The mention of arriving made her feel a little hungry, and she couldn't help but complain: "Really, if we don't go out, wouldn't someone want to come in and give us a meal?"
Xuan Tianming told her helplessly: "During this period, people came in six times. I could even smell the food, but you drove them away again."
"Did I chase him away?" Feng Yuheng didn't remember doing this at all, "How is that possible?"
"How is it impossible?" Xuan Tianming pointed to a pile of empty mineral water bottles on the ground and said, "If it weren't for these things, we would probably die of thirst."
Feng Yuheng went berserk!
When did she bring out so much mineral water? Look at the number of empty bottles. There is not even one box but more than half a box. Damn it, Xuan Tianming must have taken her out of her sleeves with so many things.
A monster.
Just as he was thinking wildly, he looked at Xuan Tianming again and was surprised to find that this girl was actually... "What are you eating?" Feng Yuheng stopped running and ran to him, staring with frightened eyes, and took the person into her mouth.
He grabbed the paper bag that was lying on the ground.
