Chapter 17 made of aluminum alloy environmental pollution

As soon as Zhang Zhimu heard that Li Yunhe and Li Dong were coming, he hurriedly said, "Please come in!" I was looking for them. That Gonggong Li told him to wait a little longer! ”

Obviously, Gonggong Li came early and was blocked by Yang Yulin.

Li Dong and Li Yunhe, father and son, came in, and Zhang Zhimu hurriedly gave up their seats.

Li Dong said: "I should have gone to Baotou a long time ago, but I wanted to follow the aluminum alloy in person about the aluminum alloy in the smelting field, which was delayed." Now I have to go. Show Mr. Zhang something good before leaving. As he spoke, Li Dong took out something wrapped in straw paper from his bag.

Li Dong opened the bag layer by layer, revealing several pieces of white metal. Zhang Zhimu immediately guessed that it must be alloy aluminum. But Zhang Zhimu didn't speak.

Li Dong took out a piece of aluminum plate and handed it to Zhang Zhimu and said: "Mr. Zhang, this is an aluminum alloy with a small amount of silicon added to copper, magnesium and manganese, and its hardness is about to catch up with steel." This is something that we have sifted through with a lot of recipes. Look. ”

Zhang Zhimu took this piece of alloy aluminum, flicked it with his fingers, and said, "Great, Yunhe, your gun carriage armor can be replaced with alloy aluminum, so that the weight of the gun carriage will be much lighter." ”

Before Li Yunhe could answer, Li Dong said, "Mr. Zhang, it may not work." Because we experimented, this alloy is good for everything, but the corrosion resistance is not good. ”

"It's not a problem, you can press another layer of pure aluminum on the outside of the alloy aluminum, so that although the hardness of pure aluminum is not as good as that of alloy aluminum, after the surface of pure aluminum is oxidized, you can protect the inside from oxidizing." Zhang Zhimu said.

Li Dong said: "Hey! That's a good idea. Alloy aluminium can be easily pressed together with pure aluminum. ”

Li Dong took out another piece of aluminum and handed it to Zhang Zhimu and said: "This is a piece of zinc, magnesium, and manganese alloy aluminum, and his strength is already stronger than ordinary steel." ”

"This is the material from which the gun carriage is made, and even the chassis of the gun carriage can be made from it." Zhang Zhimu said.

"There are several formulations that achieve this strength, but of course there are differences in other parameters." Li Dong said, "You can choose the formula according to your needs, see what you need to use it in and what processing you need to do." ”

"Li Dong, you have made a great contribution." Zhang Zhimu was a little excited.

"Hey! It's not me, those of us who do alloy aluminum. They're just crazy. They had already done a variety of recipe experiments, and they were going to do the same thing. But after doing it for a while, I found some rules, some of which are not necessary to do all, as long as a few parameters are done in the middle, you can make curves according to the laws. Li Dong said and took out another piece of alloy aluminum and said, "This is an aluminum-silicon alloy suitable for casting." There are many more types, I didn't have them all, so I'll show you these first. Wait for them to sort out the information and then give it to you. ”

"It's just great," Zhang Zhimu said, "and the most important thing to develop at the moment is alloy aluminum after adding iron." The requirement is that the conductivity should be strong and the strength should be high. In this way, there is no need to add steel wires or erect high-voltage wires in high-voltage aluminum stranded wires, and there is no need to erect steel cables. This is something that needs to be addressed. Yunhe, our speedboat can also be considered. ”

Li Yunhe nodded and said, "I didn't expect that alloy aluminum would be done so quickly." ”

"With Mr. Zhang's guidance, how can you not be happy. In the past six months, our young men have been desperate, and they can't be persuaded no matter how much they are persuaded. Li Dong said.

"You can't fight like this. Li Dong, you should reward them. Don't mess it all up. Zhang Zhimu said: "Yunhe, you have to send people to participate in their research and development work, as soon as possible to make the engine block with cast aluminum, of course, the engine cylinder should add a layer of high wear resistance and hardness alloy, so that the weight of the engine can be reduced." ”

"Good! I'll send someone to learn from them about aluminum alloys. Li Yunhe said.

"Mr. Li, the nickel and chrome ore collected by the prospecting team from the west side of the river will arrive immediately. As soon as it's confirmed, we're going to send someone to mine it right away. Because when they left, Master Qingfengzi gave them some simple measurement methods. I guess they couldn't be wrong. Then it's going to be mined soon, and this nickel and chromium are terrible things, and if you add them to the steel, the steel won't rust, it's stainless steel. Nickel and chromium alloys can be made into low-cost resistance wires. In the future, ordinary people will use electric stoves and rice cookers to cook, and it will not be a very expensive thing. ”

When Zhang Zhimu said this, Li Dong smiled and said, "Mr. Zhang is relieved. Not only do you get a lot of students every year. After they arrived, we also set up our own school and let them be gentlemen again. There are already a lot of people who can take on the task. We have already arranged this matter. As soon as the ore arrives, work immediately. We have a dedicated team to do this. Now those talented people in our metallurgy want to participate in such a team. Because it is a talented person who can come in, it is an honorable thing. ”

"Great! Mr. Li, your father and son are the pillars of our kiln! Zhang Zhimu said sincerely.

Mr. Zhang was polite. We've learned a lot from you. Li Dong said, "I used to think I was amazing. Let me be in charge of a blast furnace, and I promise to use less material than anyone else's tapping. In fact, it was like blindfolded at that time. Now we know the redox reaction, what to add, and what role it plays. Steelmaking with a clear mind. Other small steel mills came to visit and wanted to learn. I told them that it was useless to look at it like this, so let's go back and study chemistry first. ”

"Yes! Practice without theoretical guidance is blind practice. Zhang Zhimu repeated Stalin's words.

"Before I leave, there is one more thing I want to say to Mr. Zhang. Both of you are here today, so I'll tell you in front of you. Li Dong didn't answer Zhang Zhimu's words again, and said, "Mr. Zhang, our smelting plant is now a chemical plant, and the steel plant is all together. Combined, there are more than 300,000 people. I would suggest fixing our tram line there. Although we have trains going back and forth in the morning and evening, it is still inconvenient. After the tram line was repaired, I also had a suggestion, whether we could build the family area outside the smelter. The air in our smelting yard is getting worse and worse. Children are growing up, and they can't be allowed to grow up in such an environment. ”

Zhang Zhimu knows that the problem of environmental pollution has finally shown its power. "We are just studying and deciding to build the road along the railway between the kiln and the metallurgical yard into asphalt pavement. It seems that this is not enough. The tram line from Yaogang to Xishan Paozi will be opened to traffic soon. When they finished it, they immediately repaired the tram line from the kiln to the smelter. Mr. Lu helped to design the route and station situation. The matter is settled, and there is no need to discuss it again. Highway and tram roads are repaired together. Some of us are sorry for the brothers who can't live in the smelter. ”

"I think so, we will build a family area along the railway, by a small river. There, it is convenient for them to commute by tram, train and even on the road when the road is good, the air is good, the environment is good, and it is close to the kiln. Lu Chengxiang said.

"I see, I've passed through there, and there's a hill there, and there's a river down there." Zhang Zhimu said, "If we want to do it, we will do it boldly." Mr. Lu should design according to the method of building thousands of households in the first phase, plan it into several communities, and have to think clearly about commercial areas, schools, public health facilities, vegetable markets, etc. Water, electricity, gas, telephone, and heating should all be considered. Mr. Lu, let's not be afraid to spend money on this matter. Our brothers in the metallurgy are now overdrawing their lives. ”

"Good!" Lu Bingyi and Lu Chengxiang agreed unequivocally together.

Li Dong listened to Zhang Zhimu's words, and his heart was even more excited. Because it means that workers and their families can leave the heavily polluted area after work. However, it also means that the kiln will cost a lot of silver, which is not something that can be done with a few small dollars.

Lu Bingyi asked: "Mr. Li, isn't the blast furnace gas being recovered in your smelting plant?" Could pollution be reduced? ”

"There are so many polluted places that we can't completely solve it at the moment." Li Dong said.

"This pollution problem can't be solved until it's solved." "It will affect our further development in the future." When the wind is right, the kiln can smell pollution. I think that from now on, your smelting farm will take out one-fifth of the profits as the cost of pollution control. In order to study and solve the problem, it is necessary to appoint capable people to take charge of this matter, and we must pay attention to it. Gain some experience elsewhere as well. This year, we are recruiting students to set up an environmental major, which will specialize in environmental issues. We must not turn the smelter into a hell on earth. ”

Zhang Zhimu's words of hell on earth are very important, and it also shows his determination to control pollution.

"From controlling soil erosion to now controlling pollution, I think Mr. Zhang has made a big determination. I think we should pay attention to it from top to bottom, and all units that can produce pollution must self-examine. Strive to completely eliminate these hidden dangers. Lu Bingyi said.

"We are thinking about our children and grandchildren for the sake of all generations, and we must not do things that eat our children and grandchildren's food, make our children and grandchildren's wealth, cut off the roads of our children and grandchildren, and destroy our children's seeds. Some places are polluted and can never be repaired. Zhang Zhimu's words were heavier. However, everyone can also see that Zhang Zhimu is looking at problems and thinking about problems from a higher height. This height can only be possessed by those who have the world in mind and all living beings in mind. This made Lu Chengxiang, Lu Bingyi, Li Dong and Li Yunhe, who usually giggle with Zhang Zhimu, feel that they need to pay special respect to the Zhang Zhimu in front of them.

After confirming the few major things that Li Dong said, Zhang Zhimu handed the diagram of the Ferris wheel to the Li family father and son, and introduced the idea of building a Ferris wheel to them.

Li Dong looked at the picture and said: "This matter should be technically fine, we don't say anything about the quality of our good steel, and our steel gives strength parameters." You just need to use it when you design it. ”

Li Yunhe said after reading it: "There should be no big problem, but how to build it is a problem, this thing is too high, and it can't be built with such a high shelf, let alone using the method of piling soil." ”

Zhang Zhimu said: "You can put them down and build them, and then drag them up with a winch." It can also be rebuilt with a frame as high as the bearing shaft, or it can be installed one by one like the spokes of a bicycle. In short, it will be decided according to the conditions of the construction site. ”

"This Ferris wheel, I think Yunhe sent a few experienced people to design it with us, and we are strong in computing." Lu Bingyi said.

Li Yunhe smiled and said, "Hehe! I'll send someone to Xing, but I also need Li Di and Yangchang to send someone to participate. This thing control is also a big problem. ”

"Don't worry, I'll contact them." Lu Bingyi had long thought of asking Li Di and Yangchang to participate in the design of the Ferris wheel. Lu Bingyi also knows that designing such a Ferris wheel can definitely train designers. Looking at a simple Ferris wheel, the design requires a lot of complex calculations, and some design methods can be perfected through this design. Originally, when the bridge was designed, the calculations were very crude, and most of them were estimates that left a lot of room for improvement. And the control system of this Ferris wheel is not simple, and its safety needs to be considered.

The people in the house were talking happily, and Yang Yulin knocked on the door and came in and said, "You guys are not eating?" There was no food in the cafeteria for a while. ”

"Ouch! Look at it, forget about the big things. I was hungry if I didn't eat a meal. Yulin asked us to add two dishes to the canteen, and we will see Mr. Li off today. ”

"Good!" Yang Yulin agreed, and pointed outside, "What should he do?" ”

"Hey! Gonggong Li is still waiting, so let's eat together. We can't let our guests go hungry! Although Zhang Zhimu is very reluctant to see Gonggong Li now, he still admires his absolute loyalty to the emperor.

As soon as Zhang Zhimu and the others came out, Gonggong Li was obviously unhappy, but he didn't dare to get angry, "Zhang Dongjia, you left me hanging out this morning, and you still want to starve me to death?" ”

"Where, Gonggong Li, let's go, let's eat together." Zhang Zhimu said, "I asked the canteen to add two dishes. Let's go, don't you see I'm busy all the time? ”

"But I came before the next two, and you got them in and left me out." When Gonggong Li saw that Zhang Zhimu had a good face, he began to "coquettish".

"You don't know, we're talking about things together. And that's not all. Zhang Zhimu said.

After entering the cafeteria and sitting down, Father-in-law Li came to the trouble again, "Oops! I think at the beginning, I came to Yaogang, it was every time there was a greeting of good wine and meat, but now I can't, I can add two dishes, then thank God. ”

"Father-in-law Li, we regarded you as friends at that time. But you don't treat us as friends, can you blame us? At that time, we would rather not eat or drink, and when you come, we will give you food and drink. You don't deserve to be our friend, why should we give you good food and drink? Zhang Zhimu was not polite.

A few people here didn't expect that these two would be so direct.

"I know that Zhang Dongjia blames me for going to the emperor for everything. But there is no way, I was sent by the emperor. I'd rather offend my friends than live up to the emperor's trust. There's no way around it. Grandpa Li said that this was not ambiguous.

Zhang Zhimu also had to say: "Gonggong Li is loyal!" If the officials of the Ming Dynasty were like Gonggong Li, there would be no current situation. ”

When the wine and food came up, Father-in-law Li said: "I know, my friends in Yaogang hate me, and I can understand it." There's no way I can do that, so I'm not angry at me whatever you guys do to me. You have a reason for that. Gonggong Li sniffed the wine in the bowl and said, "However, can the friends of Yaogang make me miserable?" ”

"Grandpa Li, where is this?" Zhang Zhimu asked.

"You give me good wine every time, but now that I don't have good wine, I don't feel anything drunk, have you hurt me?" Father-in-law Li pretended to be bitter and said.

Yang Yulin said: "You deserve it! ”

Zhang Zhimu hurriedly stopped Yang Yulin and said: "Yulin, don't say that, for the sake of Gonggong Li, who helped Yaogang before, when you leave, bring him a few jars of wine." ”

"Oops! But I want to thank Zhang Dongjia. Grandpa Li was immediately happy.

"Gonggong Li, you are alone, you can't buy good wine to drink if you keep the silver?" Yang Yulin said.

"Oops! Miss Yulin. The emperor is very tight now, how can he give us any silver? Besides, where can you buy good wine on the good wine street in Yaogang? After Gonggong Li finished speaking, he took a big sip of the bowl greedily.

Zhang Zhimu knew that Gonggong Li and his funds were tight, but in a place like Shanxi, there were kiln gang people who he didn't dare to openly blackmail those rich people. So it's not all fake that he cries poor.

At the dinner table, Lu Bingyi said: "Mr. Zhang, we need to build a new wharf in Lanzhou, and tower cranes should be built on the wharf, so that it will be easier to load and unload goods, especially large goods." ”

"Then Lanzhou also has to build a power plant!" Zhang Zhimu said, "Without electricity, the tower crane is just a decoration." ”

"Our two-megawatt generator set is very mature, and we have to build a power plant in Lanzhou." Lu Bingyi said, "There is another problem, the section of the Yellow River in Lanzhou is going to be navigable, and the pontoon bridge will have to be demolished." New bridges need to be built there. ”

Li Dong interjected: "The steel we use to build the bridge is enough, but we only have a limited number of people who can build the bridge. I've heard that the people who built the bridge are now divided into two parts. Part of the Taiyuan Bridge was built, and part of the Hequ Bridge was built. It would be nice if these two bridges could be completed next year. ”

"I look at the Lanzhou Bridge, and we will wait for the completion of the Hequ Bridge and then build it together with the Tongguan Bridge. Moreover, it is necessary to build a road and railway bridge. Zhang Zhimu said, "At that time, we will be able to train a few excellent bridge construction teams." Several bridges will be built on Weishui soon. ”

"Oops! That's such a big difference! Gonggong Li sighed and said, "The emperor's pot is almost uncovered, but you have to build a bridge, and you are very busy." ”

"Gonggong Li, you see that we spend money, but I don't know that we earn money through construction. The emperor has to borrow millions of silver every year, is it enough to grow some food? Zhang Zhimu said. Don't think that you can only earn money by growing food and producing steel. We can also earn money by building bridges and collecting tolls. You have a million taels of silver in your mouth, and you think that it is so easy to earn silver, and we have to earn it little by little.

Of course, Gonggong Li would not say what he wanted to say at the dinner table. After the meal, Father-in-law Li, who was full of wine and food, followed Zhang Zhimu to the office. Father-in-law Li is so good, thick-skinned. Today, I saw that Zhang Zhimu gave a good face, and I was going to drink tea when I entered the house.

Anyway, Zhang Zhimu also wanted to drink tea, so Zhang Zhimu asked people to bring tea in.

After drinking tea for a while, Gonggong Li said, "The emperor has a few things to tell you this time, one is." Now the imperial court Taichang treasury is empty, and the border customs have been owed money and grain. The emperor's meaning, Shanxi has changed its strength in the past few years, is it possible to charge some fees for suppressing bandits. When Gonggong Li said this, he saw that Zhang Zhimu's face had changed. He paused for a moment and said, "Also, what you have done in the south of Qinshui is a bit excessive, and there are many ministers who have come up to you. The emperor told you to pay attention. ”

Seeing that Zhang Zhimu didn't speak, Gonggong Li said again: "The emperor urges you when you will send troops to Henan to suppress thieves?" And then the emperor heard that you have reorganized Zhou Yuji's army, don't you know if there is such a thing? ”

Zhang Zhimu knew that the emperor would not stop watching the kiln people develop on their own, and he had to do something about it. However, Zhang Zhimu didn't want to entangle with them, and said resolutely: "The people of Shanxi have not yet been extricated from their difficulties, and their taxes are being halved." They can't be burdened anymore. As for what you said about Qinshui, I don't know what you did wrong, if so, please tell them about it. The emperor asked when the troops would be sent, but we were not ready. When you are ready, you will send troops. But last time we prepared some people to go to the riverside, and they came back by order. It just so happened that the northern border was empty, so we moved to the north. As for what you said about Zhou Yuji's army, we don't know. He is the chief soldier of the border pass, and he is our parent officer, and we can't adapt them. But I know that they have not been paid for a long time, and most of the officers and men have fled hungry. Check it again! ”

What did Gonggong Li want to say, Zhang Zhimu was already impatient. said: "Gonggong Li has nothing else to do, so I won't accompany you." I have something to do in the afternoon. After saying that, he stood up and saw off the guests. Because Zhang Zhimu did have something to discuss with Chen Yufeng and Ouyang He.
