Chapter 180: Mortar Carbon Arc Lamp

Li Shoutan left Zhang Zhimu's office, and Zhang Zhimu asked Yang Yulin to invite Mr. Lu Bingyi over.

Seeing Lu Bingyi's performance during this period of time after they arrived at the kiln, Yang Yulin also saw Lu Bingyi's ability and role, and no longer felt that these people could not fight, and they could not work, they were all useless wasters, but respected these knowledgeable and talented people very much. So Yang Yulin personally came over and poured tea for Mr. Lu before withdrawing.

Drinking the fragrant Longjing, Mr. Lu seemed very happy, and said in a thick southern accent: "Zhimu, I didn't expect us to develop so fast." A lot of things just unfold like a dream. ”

Seeing that Mr. Lu Bingyi is so happy, Zhang Zhimu also feels that the progress of the kiln is still very smooth, two things done last year, for the kiln to win a little time for development, now is the time to make good use of this time, Zhang Zhimu also said with feeling: "Yes, Mr. Lu, you have all worked hard, without everyone's efforts, there will be no good situation now." We must seize the present good opportunity to grow and grow as soon as possible. ”

Lu Bingyi nodded and said, "Yes, it is already very impressive that several projects we are carrying out now have been completed. I said, Chiki, can you tell us what your next goal is? ”

Zhang Zhimu felt that Lu Bingyi should be asked to understand his thoughts, and said: "My main goal in the next step is to engage in electrification. ”

Lu Bingyi had heard Zhang Zhimu talk about the basic principles of electromagnetic fields and generators, but he still didn't understand electrification, "Can you briefly introduce what you have to do in electrification?" ”

Zhang Zhimu felt that he couldn't say it too clearly, and said: "To put it simply, all power must be electrified, and lighting must be electrified." Not only by telegram, but also by telephone. Let's take our time in the future. These things need a lot of foundations, and our industrial foundation is still in its infancy, and many things need to be perfected and solved. That's why you're here today. I just wanted to ask you, how is the last time I asked you to organize a group dedicated to ore searching? ”

Lu Bingyi knew that the matter given to him by Zhang Zhimu must be very important, and he himself felt that it was an important matter, so he organized this group very seriously, he said: "After you finished talking last time, I asked for two long-term iron-making technicians from Li Dong from the smelter, and recently from Sun Renyun, two technicians engaged in copper smelting and lead smelting. I asked Mr. Lu to help find a few people who were strong and familiar with the situation in the mountains among the newcomers. There are already more than a dozen of them. When they have nothing to do, I ask them to give lectures to each other, and they can also visit our mines. Now it seems that these people are okay. ”

Zhang Zhimu knew that Lu Bingyi was serious, "Great." Mr. Lu, these people are our treasures. If they have a mission out into the wilderness, let Liu Yun send troops to protect them, and don't let them miss anything. ”

"Okay, I'll go back and tell them."

Zhang Zhimu began to get to the point: "This time I will give them a task, I will bring back some ore from our lead and copper mines, and I want them to try to see if there is any metal zinc in these ores. ”

Lu Bingyi heard Zhang Zhimu say this, and also became interested in the zinc that Zhang Zhimu had been looking for, and said: "If there is zinc in these ores, then we can make the kind of dry battery you said." ”

Zhang Zhimu saw that Lu Bingyi was also interested, so he said: "It's not just that, in the future, we can coat a layer of zinc on the thin iron plate, and then use these zinc-plated thin iron plates to make some pots and buckets, and these things will not rust." In addition, the use of zinc will increase. ”

Lu Bingyi asked Yang Yulin to help and called several technicians from the newly established prospecting team, and Lu Bingyi followed them to listen to Zhang Zhimu's lesson.

Zhang Zhimu told them: Generally, zinc is easily associated with lead and other ores. They are generally found in the form of zinc sulfide and zinc oxide. So we want to get zinc. Or, to see if there is zinc in these ores. The ore is first calcined, and this step is to oxidize the zinc sulfide in the ore to zinc oxide. The ore and toner are then sealed in a crucible with a hole in it and heated. The distilled gas is cooled in isolated air, and what solidifies is zinc metal. This is because carbon replaces the oxygen in zinc oxide and reduces the metallic zinc, which has a boiling point of less than a thousand degrees, so it is easy to vaporize out. When the zinc vapor is condensed, it is solid zinc.

When Zhang Zhimu was lecturing, these people were desperately taking notes. After Zhang Zhimu finished speaking, Lu Bingyi said: "Zhimu." I think you'd better teach the chemistry course as soon as possible. Then we may be able to understand what you are saying. I dare say that these people are not stupid, and they will do what you say, but they will not understand what you say. ”

Zhang Zhimu also knew that it was impossible for them to understand these things theoretically at once, because there was no time for chemistry courses. It seems that it will not work without chemistry classes. Zhang Zhimu said: "Everyone do what I say first. After I finish drawing the mortar and hand it over to Li Yunhe and them, I will give you a chemistry lesson, and it will be difficult to carry out without talking about many things. ”

Several of the technicians selected by Lu Bingyi had work experience in the mine smelter, and they promised to give Zhang Zhimu a result in a few days.

After they left, Zhang Zhimu told Yang Yulin, don't bother me if there is nothing important. This is equivalent to turning away almost all of them. Yang Yulin will decide what is important according to her own judgment at any time. As long as Zhang Zhimu told him like this, it meant that Zhang Zhimu needed to be quiet, and he had to concentrate on very important things.

For several days, except for Lu Chengxiang and Liu Yun going to Taiyue Mountain and Chen Yufeng and Lu Bingyi going to Lingshui Wharf to say hello to Zhang Zhimu, Zhang Zhimu hardly saw any visitors.

In the past few days, Zhang Zhimu finally drew a sketch of the mortar.

The mortar designed by Zhang Zhimu is composed of three parts: the gun body, the gun carriage, and the seat plate. The caliber of the gun is 60mm, and the length of the gun is 100mm; The gun carriage is a bipod, which can be adjusted according to the target position, the high and low firing range is 45 ° ~ 80 °, the direction firing range is 4 ° on the left and right, and it can be folded when carrying; The seat plate is the main component that bears the recoil, and together with the bipod, it plays the role of supporting the mortar body. It should have been designed to be aimed, but that's going to be said later. For now, manual aiming is the only option.

The shell was designed to be 235mm in length and weighed around 1.5 kg. The structure of the shell consists of a fuse, a warhead, and a tail fin. The warhead is made into a drop-shaped streamline, the front part is thick and round, and the rear part is tapered backwards, and there is a cylindrical guide section in the middle, which together with the tail fin, guides the direction of flight of the shell in the barrel. The cylindrical part is also machined into three triangular air-closed grooves, because there is a 0.8mm gap between the shell and the barrel, which is to ensure that the shell can slide smoothly down from the muzzle to ensure firing. But this also leaves a chance for *** to relieve pressure. In order to solve this problem, it is necessary to open this gas closure groove, because when the explosive gas rushes out from the 0.8mm gap, it will first rush into the air closure groove, and three air closure grooves in a row will greatly solve the problem of gas leakage. The tail of the shell uses a ten-piece stabilized tail fin. Between the tail and the warhead is the tailpipe. Symmetrical drill of three rows of eight 6mm diameter holes in each row on the tailpipe. The tail pipe is packed with a cardboard shell, and a primer is installed in the middle of the tail.

Since I was not very confident about the quality of the current steel, I increased the thickness of the barrel wall a little. When Lu Wenchen comes back and brings back manganese dioxide, after he can practice manganese steel, he can make the cannon pipe wall thinner.

After drawing these pictures, Zhang Zhimu was thinking, but he didn't know how far this cannon could hit.

Zhang Zhimu, who finally finished drawing the picture, stretched his waist and came to the outside room to ask Yang Yulin to pour some tea. When he went out, Yang Yulin was the only one left in the house, Zhang Zhimu felt strange and asked, "What about our two beauties?" ”

Yang Yulin replied, "Oh, don't say it. Let Mr. Lu borrow troops to borrow them. ”

Mr. Zhang felt a little interesting, and the borrower actually borrowed it here.

Seeing that Zhang Zhimu was a little stunned, Yang Yulin continued: "Oh, it's all our newspaper's fault. It is said that the enrollment will start after the fifteenth year, but now almost all the readers in Shanxi know it, and they are afraid that they will not be able to register if they are late, so they will rush to come in advance. Lu Bingyi's people were too busy to receive and register, so they borrowed troops everywhere, so they also borrowed our people. ”

At the beginning, Zhang Zhimu didn't expect so many people to sign up, and what he didn't expect was that someone would sign up so early, saying: "I didn't expect so many people to sign up, there are so many people in Shanxi." ”

Yang Yulin said: "Shanxi people have two characteristics, one is thrifty, and the other is that anyone who has a better family has to send their children to study. Besides, where to find a place to eat and live and study for free, after studying, you know that you can still earn a lot of money by staying in the kiln. The good things in the world are gathered together, can you not earn it? ”

Zhang Zhimu clapped his hands and said, "Great, so that you can get a group of literate people." ”

Yang Yulin poured some cold water on Zhang Zhimu and said: "Okay, those who have signed up are not leaving, they are just waiting here, and some don't even have money for food." My sister-in-law is sad to death. ”

Zhang Zhimu thought to himself that Huang Yukun saw that he was too busy and didn't tell himself about it, but he couldn't let them wait now, the school house hadn't been built yet, "Didn't you notify the registration to go home and wait for the notice?" The school hasn't been built yet. We won't be able to start school until the middle of this year at the earliest. ”

Yang Yulin smiled bitterly and said, "Can you not tell them?" However, many of them borrowed the entanglements that came to the kiln, and they may not have any more money when they go back. So they said they wouldn't leave. Those who had nowhere to live slept in the haystack next to the stable. ”

Listening to Yang Yulin's words, Zhang Zhimu's heart tightened, he couldn't drink the tea anymore, and went directly to Huang Yukun.

Seeing Huang Yukun, Zhang Zhimu didn't wait for Huang Yukun to speak, and said: "Many people have left the kiln gang and gone to the construction site of Lingshui Wharf, and they will definitely pour out a lot of places, so that everyone can squeeze in and go to a few sheds for the candidates who have signed up to live." ”

Huang Yukun understood what Zhang Zhimu meant, and immediately arranged for Sister-in-law Xu to deal with this matter. After coming back, Huang Yukun asked Zhang Zhimu: "How long are you going to arrange for these people to live?" If there is food and drink, people will not leave. Now there are almost 1,000 people who have signed up, and very few people have come. ”

Zhang Zhimu said: "Don't worry about these for now, the school is on vacation, and after the student canteen opens dinner for the students, it is opening a meal for the candidates who sign up." Candidates can't be left to sleep outside tonight. ”

After speaking, Zhang Zhimu came to the registration office again and saw that there were still candidates waiting in a long line to register. Song Jiaxin, Yang Qinglian and Lu Bingyi are in the process of registering them again. When Lu Bingyi saw Zhang Zhimu, he greeted him and said, "I didn't expect these students to sign up so enthusiastically." This is all about having a certain cultural foundation, which is great. If this is cultivated well for two years, it will be a useful talent. "Speaking of which. Lu Bingyi looked back at the candidates who were queuing up to sign up, lowered his voice and said, "I think most of the candidates are from poor families, but I don't know if they have the ability to go home and come back after the notice." ”

Zhang Zhimu also saw that the candidates in line should have come in their best clothes, but compared with the people in the kiln, they were too far behind. Especially the ones who are gray and pale, and they are all malnourished at a glance, and the gap is too big compared with the ruddy faces of the kiln workers.

Zhang Zhimu and Lu Bingyi were talking, and a carriage stopped next to it, and a brightly dressed boy got out of the carriage. When the boy asked that this was the registration office, he didn't line up, and went directly to Song Jiaxin to ask for registration. Song Jiaxin said politely: "Look, this son, everyone is queuing, please line up too." ”

At this time, Childe's entourage got angry and said, "What's the matter, let's get Childe and those people in line?" Don't you look at who my son-in-law is? ”

Song Jiaxin also worked in the kiln for a while, especially when she saw it, Zhang Zhimu and Lu Bingyi were watching from the side, this girl was neither humble nor arrogant and said: "I'm sorry, in our kiln, everyone is equal." You have to follow the rules, please get out of the way, I'm going to register this candidate. ”

Zhang Zhimu was very satisfied with Song Jiaxin's performance, but he didn't want to cause any more unpleasant things, so he walked over and said to the son: "This young lady has made it very clear, our kiln gang is a place where everyone is equal, if you still want to register here, please go to the back and line up, otherwise please don't waste time." ”

The boy also knew that the kiln was not a place where he could go wild, so he returned to the car stupidly, thought for a while, and still lined up at the end of the line.

Zhang Zhimujue's son, who can be so humiliated, can not leave, continue to queue up to register, I feel that this person really wants to study in the kiln.

Zhang Zhimu said to Lu Bingyi again: "I have arranged for Huang Yukun and them to pour out some sheds, so that the candidates who signed up can live with their families at night, and they will take care of the food together." ”

At this time, Sister-in-law Xu came to the registration office and sent a lot of meal tickets to the registration office, and Sister-in-law Xu said to Zhang Zhimu and Lu Bingyi: "Yukun Deng said, when you register, you will give everyone a meal ticket, and the place to live has been arranged, so that the candidates who sign up can go to live with the registration card." You can arrange for someone to send the candidates here. ”

Lu Bingyi was very happy to hear this, and he said loudly to the candidates who registered: "Listen, all the candidates who have registered, don't forget to get a meal ticket when you register." With this meal ticket, you can go to the dining hall to eat. In addition, you can use your registration certificate to rest in the accommodation arranged for you by the kiln gang, and you no longer have to sleep outside. ”

All the candidates who signed up showed smiling faces, but Zhang Zhimu didn't stay long when he saw the smiles on the faces of these candidates. Because they all understand that now they are facing an opportunity to change their fate, and the pressure in their hearts is enormous.

Seeing this, Zhang Zhimu felt a little unbearable, and said, "Mr. Lu, let's do this." After the fifteenth registration, the exam was held immediately, and during this time, we took care of the food and lodging of these people. After passing the exam, these students who are willing to go home and wait will go home and wait, and if they are unwilling to go home, we will arrange for them to practice first, and Li Yunhe will arrange them to practice in the workshop if they learn machinery; those who study military affairs are arranged by Liu Yun; Qingfeng sub-arrangement of learning chemical engineering; The art is arranged by Liu Banzhu. In short, the people are arranged, and they are stable. As soon as the school is built, classes will be available. ”

Lu Bingyi clapped his hands and said, "It's great to do this." ”

After reading this, Zhang Zhimu was about to leave, and suddenly came to a question: "Mr. Lu, how did the matter of Lingshui Wharf decide?" ”

Lu Bingyi said: "When we arrived at Lingshui Wharf, we talked to Commander Fan about our ideas, and Commander Fan was of course happy to hear it, and he put forward some suggestions on the construction of castles on both sides of the dam. In the end, it was decided to connect the entire defense structure of the pier to form an overall defense pattern, so as to fully ensure the safety of the entire pier and the dam lock. I've left people to do the specific design, mainly to design the underground part first, so that their earthworks can be excavated now. ”

Zhang Zhimu knew that he had been practicing behind closed doors for the past two days, and Chen Yufeng and the others had no chance to say anything to him when they came back. It seems that Yang Yulin is very qualified to guard the door.

As soon as Zhang Zhimu opens the door, things will continue.

Early the next morning, Li Shoutan was already waiting for him, and Zhang Zhimu knew that the refining of graphite must have been completed. Sure enough, as Zhang Zhimu expected, Li Shoutan led a few people to carry an altar, and Zhang Zhimu gently pinched out the gray-black graphite powder in the jar with his fingers, feeling very delicate and slippery.

Zhang Zhimu said to Li Shoutan: "I will first use this thing to make a sun for everyone to see." ”

Li Shoutan saw that this was Zhang Zhimu and expressed satisfaction with their work, and said: "Mr. Zhang, we have a total of more than a dozen jars of such graphite powder. If it's enough for the time being, we'll go to the smelter first, which is too busy right now. When the lecture began, we all came back to listen to the lecture. ”

Zhang Zhimu said: "Okay, you guys are busy with things over there first, these graphites are enough for the time being." ”

Li Shoutan left, and Zhang Zhimu asked Yang Yulin to find Li Yunhe. In Zhang Zhimu's office, this is like this, you come and go.

Obviously, Li Yunhe knew that Zhang Zhimu asked him to come because he had something new for him to do. As soon as he entered the house, Li Yunhe asked, "Mr. Zhang, what's new?" ”

Zhang Zhimu likes Li Yunhe very much, and thinks that choosing Li Yunhe to be in charge of this stall is the right person, Zhang Zhimu pointed to the drawings on the table and said: "You take a look first, can you understand this drawing?" ”

Li Yunhe said while looking at the drawings: "In order not to delay time, you better hurry up and talk about it." ”

Zhang Zhimu started with the fuze to Li Yunhe, because Li Yunhe had designed the fuze of the bow mine and the crossbow mine, so he quickly understood the fuze designed by Zhang Zhimu. However, Li Yunhe said: "How big the elasticity of those springs is still to be tested." ”

"No way, everything, you have to try to come." Saying that, Zhang Zhimu explained to him the structure of the shell and the firing principle. Finally, he was told about the mortar, the overall structure and the functions of the parts.

Liu Yun said: "I can only say that I understand it now. I'll wait for you to study it with you, and I'll come back to you if you don't understand. ”

After talking about the mortar, Zhang Zhimu pointed to the jar in the house and said, "Look. This is the purified graphite powder made by Li Shoutan. ”

Li Yunhe also pinched a little graphite with his hand and asked, "What new things are you going to use this thing for?" ”

Zhang Zhimu said: "I want to create a sun at night so that everyone can work normally at night. ”

Li Yunhe was a little puzzled, but he knew that Zhang Zhimu would not be crazy about what sun, he must be doing something new, and said, "You just said what to let me do?" ”

Zhang Zhimu looked at Li Yunhe's expression and said, "I want you to use these graphite powders to press them into pencil-like thick and pointed graphite rods on the hydraulic press." Don't believe me, I'll really make a sun out of them when the time comes. ”

Li Yunhe still didn't believe that Zhang Zhimu would use this thing to create the sun, and Zhang Zhimu was not an immortal. However, his arrangement for Zhang Zhimu will be implemented.

Li Yunhe said: "Then you have to make a mold with good steel." Wait, I'll press you out a graphite rod. ”

Zhang Zhimu thought for a moment and said, "Wait a minute, I'll draw you a sketch, and you can make two kinds of graphite rods according to two sizes like this." ”

Zhang Zhimu wanted to make the graphite electrode for the carbon arc lamp, and Zhang Zhimu asked them to make this graphite electrode with a diameter of 20mm and a length of 400mm with a pointed electrode. The thin pencil is as thick as a pencil, and Zhang Zhimu sets the size to be 8mm in diameter and 20mm in length.

This thin one is what Zhang Zhimu is going to use for the test.

Zhang Zhimu asked Li Yunhe again, "Have you been there recently to see how their power plant is doing?" ”

Li Yunhe replied: "It's almost right, they have moved more than a dozen small motors over and are ready to do experiments." Fifteen years ago, it should be fine. ”

Zhang Zhimu said: "If they can do a good job before the fifteenth day, when the fifteenth day hangs the lamp, I will hang a headlamp for everyone that can be seen several miles away." ”

Li Yunhe felt that Zhang Zhimu was very serious, and asked Zhang Zhimu: "Can you tell me more specifically, how do you make the sun?" ”

Zhang Zhimu said: "I want to make a kind of carbon arc lamp that will emit light as bright as the sun when it is electrified, and at that time, this kind of lamp will shine out a few miles away, and you say that this kind of lamp is not the sun." ”

Li Yunhe asked with some hesitation: "You can make a carbon arc lamp with these graphites?" ”
