Zheng Sen went to Nanjing to arrange the immigration affairs in a hurry, and entrusted the main things to Kong Zhang and Ma Shiying, and then went to the old museum to find Li Xiangjun. Pen ~ fun ~ pavilion www.biquge.info

In the past few days, in addition to using the silver that Zheng Sen put at her to hire literary and artistic personnel, she really borrowed more than 1,000 taels of silver from others. Now that Zheng Sen is back, he naturally wants to pay back the money first. In addition, there is one more thing that needs to be addressed. That is, since his relationship with Li Xiangjun has now been approved by Zheng Zhilong, it may not be appropriate to continue to let Li Xiangjun stay in Qinhuaihe, so he can also take advantage of this past to mention this matter to Li Xiangjun's adoptive mother Li Zhenli.

Zheng Sen arrived at Meixianglou and saw Li Xiangjun, so he invited Li Zhenli and raised the matter with her: "Mother Li, Xiangjun will follow Xiaosheng in the future, and Xiaosheng is not from Nanjing, so he naturally wants to take Xiangjun back to his hometown." This time there are thousands of mountains and rivers, I am afraid that it will be difficult to come to Nanjing to see Li's mother at all times. If Mother Li is reluctant to Xiangjun, she can also go back with us. I have a troupe in Taiwan, and now Master Su Kunsheng is helping to take care of it, and Li's mother also knows about it. If Mother Li goes, she doesn't have to worry about being bored, she can train those children with Master Su and them. Xiaosheng is willing to give 2,000 taels of silver to Li's mother as a settling-in allowance; If Li's mother is reluctant to Nanjing, Xiaosheng will put this settling-in fee here first, and Li's mother will collect it first. ”

Li Zhenli naturally knew that the two thousand taels of silver were not the so-called "settling-in fee", but the cost of combing Li Xiangjun. Speaking of which, in my Ming Dynasty, combing a woman, even if it is a so-called "famous prostitute", can't spend so much silver. Li Jia in "Du Shi Niang's Angry Sinking Treasure Chest" in "Warning to the World" bought Du Shi Niang, but it only cost three hundred taels of silver, in the original history, when Hou Fangyu combed Li Xiangjun, the flower was actually quite used here. Zheng Sen is willing to give so much, firstly, because the Zheng family is rich, and secondly, he also told Li Zhenli that he will definitely treat Li Xiangjun well. So Li Zhenli smiled and said:

"Where did Zheng Gongzi say, just the settling-in fee, where so much money was spent. Besides, now Zheng Gongzi is running for disaster relief, and he needs silver, if he stays with me too much, he will be scolded by someone pointing at my back. I heard Xiangjun mention things in Taiwan, and I know that things in Taiwan are much cheaper than in Nanjing, and I will leave five hundred taels of silver, which is enough to settle down. The other sons will be put to good use first. Even if the son did a good deed for me, he accumulated yin virtue. Could it be that when I went to Taiwan and helped my son train those children, could my son still not pay me? But then again, my salary can't be much less than Su Kunsheng's. ”

Zheng Sen wanted to persuade a few more words, but when he saw Li Xiangjun quietly shaking his head at him from behind, he said: "In this way, Xiaosheng obeys his fate." ”

"Zheng Gongzi, there is one more thing, I want to make it clear to you first." Li Zhenli said with a straight face, "Xiangjun, this child was brought up by me, and in my heart, he is really the same as his daughter." Now that she is with Childe, that is also the fate of her and Childe. It's just that this child has been pampered since she was a child, and I like to spoil her, and she has never ...... Now that she is with her son, her family can't bully her because of her origin. ”

When Zheng Sen heard this, he turned his face to look at Li Xiangjun, but when he saw her hanging her head and looking worried, he smiled and said, "Mother Li, don't worry." My father has actually seen Xiangjun and likes Xiangjun very much. Although I can't marry Xiangjun as the main family, I will never let people bully her casually. ”

"If there is a big lady in the future......" Li Zhenli still seemed a little uneasy.

"Mom......" Li Xiangjun said in a low voice, she knew that Zheng Sen was a very assertive person, and with his current status, he was afraid that no woman in the world could do a lion's roar in front of him. Since he said that he won't let people bully him casually, it's already a very good guarantee, and if he says more, I'm afraid it's not good.

Li Zhenli is also a smart person, and when she saw Li Xiangjun open her mouth, she stopped talking and said, "I don't know when Zheng Gongzi plans to go back?" ”

Zheng Sen hurriedly replied: "Originally, I was going to wait for the disaster relief here to come to an end before going back, but I didn't want something to happen in Taiwan a few days ago, so Xiaosheng can only arrange the general things here, and he will go back in two days." ”

"So urgent?" This was quite unexpected by Li Xiangjun.

"yes, but it's not a bad thing." Zheng Sen said with a smile.

……

Zheng Sen said that there is something not an excuse, but that something very important is really happening in Taiwan. A few days later, Zheng Sen took Li Xiangjun's mother and daughter back to Beigang on the Feiyan. As soon as he got off the boat, Zheng Sen ordered Li Xiangjun and them to settle in the small building where they had lived, and he got into a carriage directly and went to the iron factory located by the muddy water stream.

After entering the factory, Zheng Sen got out of the car and saw Su Quanyou, the director of the porcelain factory, running over.

"Director Su, did you succeed?" Zheng Sen asked.

"It's scrapped a lot, but it's still some, I've just tried it, it works, it's easy to use!" Su Quanyou laughed so hard that his eyes and nose fell together.

At this time, Liang Yu, the chief engineer of the iron factory, also followed, handed a three-foot-long iron pipe to Zheng Sen and said: "Major General, this is made of cast steel smelted from the crucible burned by the director of the Su factory. ”

Zheng Sen took the pipe, looked at it carefully, and then looked into the pipe by the light, and saw that several rifling wires had been pulled out of the pipe. So he was very satisfied and said, "Yes, yes, take me to see this crucible cast steel." ”

A few people led the way in front, and after a while, they entered the factory and saw a large black crucible like a bowl. This is the graphite crucible fired by Su Quanyou.

When the Science and Technology Tree Plan was first formulated, Zheng Sen knew that in the development of human industry, the large-scale production of steel was of decisive significance. Naturally, a lot of resources have been invested in steel. Zheng Sen knew that the earliest and easiest steelmaking technology close to industrialization for mankind was crucible steelmaking. Crucible steelmaking is relatively technically difficult, and the quality of the steel produced far exceeds that of ordinary methods, until the invention of electric arc furnaces, crucibles were the best choice for refining high-quality steel. It's just that there are still two difficulties in this technology tree, one is how to achieve enough to melt wrought iron, that is, a high temperature of about 1,500 degrees. In this era, neither the East nor the West has yet to find the means to achieve such temperatures. Of course, if you don't make electrolytic aluminum first and then apply thermite at any cost, you can reach a temperature of more than 2,000 degrees, but in this era, if you really want to play like this, the iron you play with is estimated to make gold cheap.

Zheng Sen's approach is as follows: First of all, in the traditional iron-making furnace, cold air is blown in by a blower, and Zheng Sen knows that the air blown by the blower in the iron-making factories of later generations must be heated before it is sent into the furnace. Zheng Sen knew that this heating was done by using the heat of the exhaust gas produced by the furnace, and now the pipe of the hydraulic blower of the iron factory has a long section hovering in the exhaust chimney of the blast furnace, relying on this trick, the temperature of the furnace has been greatly increased.

Another trick is to use coke instead of coal. Coking is actually not too difficult, in this era, in fact, the Chinese are already using the soil method to make coking, but this is super polluting, and many valuable by-products, such as coke oven gas, such as coal tar, but Zheng Sen has not much technology to use at this time, at least now, these things have been wasted a lot. And it also brings serious pollution. Zheng Sen's methods of dealing with pollution are absolutely worthy of the teachings of the party and the people in his previous life, he did not control pollution before it happened, and even did not even pollute first and then clean up, the only targeted measure is to arrange the coking plant in a downwind direction far from Beigang.

Relying on the hot air and coke, it is true that the temperature of the blast furnace can be greatly increased, but if you want to make steel, such a temperature is not enough, and if you further increase the temperature, you will encounter a new problem, that is, the problem of materials. Zheng Sen knew that refractory bricks should be used in steelmaking furnaces, but Zheng Sen didn't know how to fire these refractory bricks, but fortunately he knew that there was a material in nature that was particularly resistant to high temperatures, so it could be used to make steelmaking crucibles. This material is natural graphite.

Zheng Sen knew that natural graphite could be used to make high-temperature resistant crucibles, but how to fire graphite crucibles, he only knew that it seemed to be burned with kaolin or something. But in the end, how to proportion, how to modulate, how to sinter, Zheng Sen really doesn't know. But now that the general direction is there, the rest is nothing more than burning money. Graphite produced in Shandong, as well as kaolin from Jiangxi, was transported to Taiwan by boatload for firing experiments, and for more than a year, Su Quanfa's porcelain factory did not know how many kiln prototypes had been burned, and it was only recently that a usable graphite crucible was fired.

With graphite crucible, it is easier to fire graphite refractory bricks, and the final problem is solved, using coke and hot blast, in the furnace built of graphite refractory bricks, put in the graphite crucible, put the wrought iron and a part of the pig iron fried by the fried steel in the crucible, and then heat it to 1,400 to 1,500 degrees, the wrought iron will completely melt into liquid, and various impurities will also float on the liquid surface.

Compared with the steelmaking method of later generations, the cost of steelmaking is high and the output is small. However, this is much better in terms of cost and speed than the traditional method of forging carburizing or frying steel to obtain steel. It's barely enough to produce energy. For now, this is the simplest steelmaking method that Zheng Sen and the others can master. With mass-produced steel, Zheng Sen's entire business can be greatly pushed forward.
