Section 16 Meetings - Machinery and Chemical Industry
The topic turned to the machinery manufacturing industry, which is the business of Mr. Wen, and this topic mainly revolves around what equipment to carry. Zhan Wuya has contributed to a small machine factory, and he informs about the types of equipment.
"Will these machines be able to produce all the special machinery we need? Well, let's say, boilers? ”
"Theoretically, it's completely possible, just take my small factory, there is not much equipment, but as long as there are suitable materials, the general machinery and equipment can be sorted out for you. Of course, my factory mainly processes all kinds of parts for people, and I have not done complicated sets of machinery. There are also some small parts that we don't usually make," Zhan Wuya scratched his head, he was not used to standing on the stage like this and being consulted, "for example, all kinds of standard parts, oh-" He realized that many people didn't know what standard parts were, so he explained, "It's the mechanical parts used for fastening connections, such as screws, screws, washers, etc., which are best made with special equipment." ”
"Of course, you can make these things, but it's a little bit of a hassle. We can do some special machines to manufacture these standard parts.
"There are all kinds of castings, gears, bearings, etc., which are not something that a small machine shop like ours can make. It involves specialized equipment, and some also require heat treatment and electroplating. I don't know much about this, I usually buy ready-made parts directly, or hire someone to process them. ”
"But gears and bearings are very useful, and if they can't be manufactured, it means that the equipment manufacturing industry is out of play."
"Then bring special equipment, and if you want gears, you can use a gear hobbing machine. The bearing is more difficult......"
"The equipment of the full set of bearing factories may exceed 10 million."
"Tens of millions is a trivial matter, where can you find so many skilled workers to do?"
"It's still necessary to go to the local law. It is necessary to try to use the existing equipment, and the investment in professional equipment is too large. ”
"The material needs a heat treatment furnace. The bearing retainer and mounting balls can be done by hand, and if they are fixed, they can be fixed with a punch. ”
……
Then it entered a more complicated discussion stage, and after muttering for a while, the discussion of the industrial group subsided, and probably reached a consensus on the manufacturing methods and equipment of gears and bearings, and some people began to write lists, Xiao Zishan guessed that it might be something like a list of equipment.
Wen Desi spoke at this time: "I propose that in order to unify the accessories, there is no need to bring shearing machines and bending machines, and a few more punches can be replaced." Try to bring as many tools and grinding wheels as possible, in addition, there are no milling machines and heat treatment furnaces in the machine factory, which need to be brought. ”
"If you want to be as complete as possible, you also need to have broaching machines and boring machines, and the number of lathes should be more." Jiang Ye, who has been a lathe worker for eight years, spoke, "After all, a lathe is the most basic machining equipment. ”
"How about 8 lathes?"
"Less, 12 units. This stuff is very useful. ”
"What about the forging press? This should not be missing. ”
……
While the mechanical discussion was in full swing, many people began to yawn, but due to the restriction that the topic was not over, they began to discuss in their own small group, and for a while the conference room was full of buzz.
Wang Luobin stood up suddenly, and did not ask the moderator for his opinion - the industrial group completely ignored the moderator of the meeting - "A small foundry is also needed, this must not be forgotten." And if you want to build an engine in the future, this is a necessary condition. It is said that the single-cylinder diesel engine is simply a universal machine: it can plough the land and plant seedlings, the water can drive the boat, the mountain can generate electricity, and the road can transport people and pull goods. ”
"Small engines aren't a big problem. Cast iron is used for general agricultural single-cylinder engines. HT250 is good: good shock absorption; Casting has good fluidity and is easy to form. Easy to cut during machining. ”
"When it comes to casting, I think of the problem of mold opening in manufacturing, which is a professional business, and having equipment can't make you a good product, you have to have a mold. The equipment required by the modern mold industry is too rebellious: 3D modeling, electrical discharge machining, ...... It's not easy to do. ”
"It's not that exaggerated. What you're talking about is now, in the past, the process designer designed and drew the mold drawings, and then the machined parts, and the zuihou was assembled by the fitter - the level of the fitter is very important. ”
……
Slowly, the mechanical discussion subsided, and the industrial team used a lot of paper, and it seemed that they were all a little confident. Wen Desi saw Wang Gong writing there with great interest, and couldn't help but worry about whether this purchase order would be too long.
"I'm Ji Siwei." A man with a beard on his face stood up, although he had a full beard, his face was a baby face, "I strongly protest on behalf of the chemical team. When he said the words "chemical group", he deliberately accentuated his tone, "The chemical industry is a very important industrial category, how can it be indiscriminately classified into the industrial group?" They're all mechanical, and they don't have a line with us at all! ”
"As for the grouping issue, we will discuss it later, but first tell me what you think about the chemical industry."
"Triacid, dialkali. Our goal is to solve the production of these things.
"I'll start by popularizing the basic knowledge of chemical engineering. The chemical industry we are going to talk about here belongs to heavy chemical industry and is the foundation of all chemical industries. ”
This time it was the mechanical staff's turn to yawn, but most of them watched his speech with interest.
"The chemical industry is one of the most versatile industries in all industrial fields. The products of the chemical industry are rarely end products in their own right, and these products are mainly utilized by other industrial sectors. For example, sulfuric acid is the fertilizer industry, soda ash is the glass manufacturing industry, synthetic ammonia is the zha medicine and fertilizer industry, and so on. As long as we can solve the manufacturing of these basic heavy chemical products, we can solve many material manufacturing problems.
"Do you know how dependent you are on chemicals in your life? You don't know, that's why you get chemicals and machinery together! He shook his head, "Tragedy! ”
"Don't express so many feelings, just talk about chemical engineering."
"Our chemical infrastructure needs a set of synthetic ammonia and combined alkali production system and a coking chemical system, which can roughly meet our basic needs, especially synthetic ammonia equipment."
"What is coking equipment?"
"Coke oven?"
"No, it's simply a co-manufacturing facility that uses coal tar to make various chemical products. It is possible to make sulfuric acid, phenol, *, dyes, and by the way, sulfonamides. ”
"Sulfonamides are useful so that we have antimicrobials."
"Of course, this production is not very high, but it is generally enough."
"What about synthetic ammonia, is it used as fertilizer?"
"It's been of great use to us. In short, without ammonia, we can't produce nitric acid.
"Without nitric acid, we wouldn't be able to come out with a zha drug
"And, of course, the fertilizer industry, which is more dependent on synthetic ammonia."
"In addition to complete sets of equipment, it is necessary to prepare some spare chemical equipment: such as comprehensive towers, absorption towers, decarburization towers, distillation towers, saturated hot water towers, various reactors, pressure-resistant pipelines, acid pumps, heaters...... I think you have to have 500-600 tons of material to be enough. ”
"Can't these things, well, be homemade? Our machinery industry is still relatively complete. ”
"Material issues." Ji Siwei said, "Unless materials such as stainless steel and polyethylene can be produced soon, I think it will be difficult to produce chemical equipment within ten years." ”
"What about glass and ceramics? The Eighth Route Army's military industry used a water tank as a reaction tower to make sulfuric acid. Moreover, many of the Great Leap Forward soil chemical equipment also use these things. Rodoe spoke again.
"I don't know. If you have the conditions to purchase modern equipment, there is no need to use soil equipment. At least in terms of production efficiency, it will be much improved. Even the production environment is stronger than the soil method. If any of you like to use a tank to make sulfuric acid, you have to think about your teeth. ”
"I would like to ask, with all this equipment, can we establish an organic chemical industry?"
"This, I'm afraid it's difficult." Ji Sihui thought, you really have to look at Shu, is this organic chemical industry so good?
"Then you can't get nylon and elastomer." Someone is lamenting.
"What do you want nylon, stockings?" Someone teased.
"Black silk, shredded meat...... No one is missing. ”
When the atmosphere began to become a spoof, Xiao Zishan had to dispel everyone's creativity and bring him back to the topic.
"It takes 11 years for rubber to tap, but there are many places where rubber needs to be used."
"We don't want to make condoms, we have to be rubber."
This caused another burst of laughter, and the meeting once again fell into an infinite stream of discussion.
Xiao Zishan finally settled everyone down.
"I think you want to have organic chemicals for plastics," Ji Siwei nodded to the person who proposed to build organic chemicals, "Although plastics are our most common daily necessities, they involve organic chemicals that are very complex and we are unlikely to make them - it's not just a matter of raw materials." But we can make celluloid and bakelite. ”
"Bakelite is useful."
"If we want to build an electric system, bakelite is very useful, but rubber is also ......"
"The discussion about rubber will be explained by the agriculture team in a moment."
