Feng Yu Heng was quite interested in being able to walk sideways, but she had to face a very troublesome problem: teaching Xuan Tianming how to read simplified Chinese characters.
She told Xuan Tianming: "I write like this because I'm lazy. I want to write less. Anyway, it's fine as long as I know what it means."
Xuan Tianming didn't believe this and bluntly said: "You can just tell me that it's Persian."
She spread out her hands: "Although I really want to say that, in reality, it really isn't Persian. If I insist on saying it, it will be exposed sooner or later."
Xuan Tianming wanted to say that there would be many things that would be exposed in the future, but in the end, he couldn't bear to expose her. Under Feng Yu Heng's guidance, he began to read the simplified Chinese "Feng's Guide to Making Steel".
The so-called "Feng's Guide to Making Steel" was actually Feng Yu Heng's handwritten steel-making steps. From making slag and extracting slag, to increasing silicon, to controlling the final point, to producing steel, there were a total of nineteen steps. Each step had a detailed explanation and explanation. Moreover, for some problems that couldn't be solved in the current era, she had done her own analysis and found replacement methods. She had also explained them in detail. However, this replacement method hadn't been tested yet, so she didn't know if it would succeed. This was also one of the biggest difficulties in making steel.
Xuan Tianming's ability to accept things was quite fast. Feng Yu Heng told him some rules for reading simplified Chinese characters and guided him through a few lines. He was able to figure out the rest on his own, but there were some technical descriptions that still needed Feng Yu Heng to explain.
Two hours later, he finally put down the guide and said to Feng Yu Heng: "Producing steel is not an easy task. After looking at this, I am even more certain of its difficulty. I can't guarantee success, but we can at least try. If one time doesn't work, then try twice. If two times still don't work, then try twenty times. No matter how long we try, I believe we will succeed. God won't be so merciless to me, Dashun. "
She nodded and began to tidy up the furnace as she said, "This has nothing to do with God's mercy on Dashun. Although I have never made steel myself, I have seen others do it with my own eyes. It's just that we don't have some of the equipment that we need, so those alternative methods are where we mainly experiment. "
Xuan Tianming also became serious. He turned his wheelchair and began to prepare with Feng Yu Heng.
The first step of making steel was to create slag. Compared to the following steps, this was relatively simple. In other words, from the creation of slag to the extraction of slag to the stirring of the molten pool, everything was simple. It was just the bottom blowing of the electric furnace. It was not known if the existing huge bellows could achieve this. This was especially true for the melting, oxidation, and decarbonization stages, which were the real test of their skills.
The two of them couldn't care less about their image. Even Xuan Tianming got out of his wheelchair and sat on the ground. Feng Yu Heng was the technical director and assistant, while Xuan Tianming was the main operator.
"Creating slag is the operation of adjusting the composition, alkalinity, viscosity, and reactivity of the molten slag during the production of steel and iron. The goal is to refine the metal with the required composition and temperature. " Every time she said a word, he would do a step. The amount of each material, the temperature, and the time of each addition were all strictly regulated. He didn't dare to carry it out at all. Unfortunately, after the slag was extracted, Feng Yu Heng shook her head. "No, the oxidized slag isn't clean enough. It's easy to cause phosphorization." After thinking about it again, she said, "I don't think there's a problem with other things. The only problem is the control of time. Although we calculated very carefully, it's still not accurate enough."
Xuan Tianming nodded and said, "Again."
"Wait." She held his wrist. After thinking about it again, she simply removed a wall clock from the wall of the space.
Xuan Tianming watched as she pulled out something that was so big that it was impossible to fit into her sleeve. His hair stood on end. Fortunately, he had the experience of the soldiers being poisoned years ago. After all, he was someone who had seen this girl pull out a butt from her sleeve. Although he was shocked, he wasn't so shocked that he would treat Feng Yu Heng as a monster. Moreover, Xuan Tianming understood that if something wasn't normal, it would be a demon. If that was the case, his little wife would have been drowned in a river and sacrificed to the gods.
"This thing is called a clock." Feng Yu Heng felt guilty and didn't dare to explain the origin of this thing. She only talked about how to use the clock, avoiding the important points and dwelling on the trivial. She told Xuan Tianming, "There are three hands on this clock. One is called the hour hand, one is the minute hand, and the last one is the second hand. It's the same principle as the sundial used in Dashun. The only difference is that the sundial has twenty-four hours, while the clock has twenty-four hours. That is to say, two hours on the sundial is equivalent to two hours on the clock. "
She patiently explained the clock to Xuan Tianming and said, "The process of producing the dregs takes one hour and forty-five minutes. This time, we'll use the clock to time it accurately and try again."
"Okay." He nodded and pointed to the twelve o 'clock position on the clock. "When the minute hand and the minute hand reach there, we'll start. This time, we can't be off by even a little bit."
The two of them finished all the preparations to try again. They stared at the last two minutes on the clock, second by second. Finally, the second hand ticked past the last bar and fell at the twelve o 'clock position. Xuan Tianming's hands immediately began to move.
Feng Yu Heng also stared at him nervously and said the steps one by one as he moved.
Xuan Tian Ming remembered it very quickly. After personally experimenting with it the last time, he was able to completely remember the entire process. His movements were very practiced, and it looked as though he was a veteran. Even Feng Yu Heng could not help but sigh that this person's brain was really good. No matter what he did, he was so good at it.
Finally, all the processes were completed. All that was left was to watch the clock. Last time, when they were watching the clock, they could occasionally say a few words. But this time, even with the clock standing there, the two of them were even more nervous. They didn't say a word to each other. Their eyes were fixed on the clock, not daring to look away.
When there was only one minute left, Feng Yu Heng whispered a reminder. "Get ready to start the furnace. There are two seconds left."
Xuan Tianming nodded. His hand was already on the handle of the furnace.
Finally, the last minute was over. Almost at the same time as the second hand ticked to twelve o 'clock, Xuan Tianming opened the furnace. A wave of heat hit him in the face. When he took out the shovel, he heard Feng Yu Heng shout, "It's done!"
When these two words came out, even Xuan Tianming felt a burst of excitement. He stared at the slag on the shovel and asked Feng Yu Heng with uncertainty, "It's really done?"
Feng Yu Heng nodded. "It's done! Not only did it succeed, but you also made the best slag. With these things, we have a solid foundation for the next step. Xuan Tianming, you're really capable! "
She praised him sincerely. Xuan Tianming also breathed a sigh of relief. This was only the first step. If they had to repeat the first step too many times, their morale would be lowered.
"We still have to continue to make slag." Feng Yu Heng said, "Although we're just trying to make a piece of steel, we have to experience countless failures in the middle. Every time we fail, the previous materials will be scrapped. Making slag is the first step. We have to ensure that the materials for the first step are sufficient. Only then can we continue. "
Xuan Tianming nodded. "Okay, then let's make a few more furnaces. After all, we have to be more proficient." As he spoke, he moved the finished slag to the side and added more materials to the furnace. He began a new round of slag making.
This time, he was more proficient than last time. He had a clearer grasp of the timing of the clock. He almost didn't need Feng Yu Heng to remind him again. He could operate the entire process by himself.
However, Xuan Tianming didn't expect that this time, his wife shook her head. "No, the quality isn't as good as last time. It's probably because you didn't control the fire well at the beginning. It's a bit rushed. You have to be more steady."
"Then let's do it again." He didn't say anything else and started again.
The fourth time, success.
The fifth time, success.
The sixth time, failure.
The seventh time, success.
Feng Yu Heng calculated in her heart. At the beginning, they would fail after two successes. Sometimes, they would fail twice in a row. It wasn't until Xuan Tianming's sixteenth attempt that the success rate began to rise. He produced ten consecutive times, and all of them were excellent.
Feng Yu Heng told him: "You've already completely grasped the essence of slag making and slag making. If the finished products we've produced are as expected, then it should be enough to squander. Let's do these first and continue. If it's not enough, then we'll come back and make up for it. "
Xuan Tianming nodded. He 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 timing you mentioned, it should be time for dinner now. Moreover, it's the second day we've been here. Heng Heng, you haven't closed your eyes for a day and night. You haven't eaten anything either. "
"Ah?" She was a bit surprised. She had been focused on doing one thing in this cave. She didn't feel the passage of time at all. But she didn't expect that a day and night had already passed outside. It would have been better if he hadn't mentioned it. Now that he mentioned it, she felt her stomach rumble with hunger. She couldn't help but complain: "Really, if we don't go out, won't someone come in and give us food to eat?"
Xuan Tianming helplessly told her: "During this time, there were a total of six people who came in. I could even smell the food, but they were all chased away by you."
"I chased them away?" Feng Yu Heng didn't remember doing this at all, "How is that possible."
"How is that not possible?" Xuan Tianming pointed at the pile of empty mineral water bottles on the ground and said: "If it wasn't for these things, we'd probably die of thirst."
Feng Yu Heng went berserk!
When did she take out so many mineral water bottles? Looking at the number of empty bottles, even if it wasn't a box, it was at least half a box. Damn, she took out so many things from her sleeves. Xuan Tianming must think of her as a monster.
Just as her thoughts were running wild, she glanced at Xuan Tianming again. She was surprised to find that this guy was actually … "What are you eating?" Feng Yu Heng stopped her rampage and rushed to his side. She stared at him with frightened eyes and snatched the paper bag from his mouth.
Then, then she was speechless.
What had she done in the past day and night?
