Chapter 20 Conference - Machinery and Chemicals

The topic was transferred to the machinery manufacturing industry, which is Mr. Wen's business, and the topic mainly revolved around what equipment to carry.Zhan Wuya has already contributed a small machinery factory, and he notified the types of these devices.

"Can these facilities produce the various specialized machinery we need? Well, for example, boilers?"

"Theoretically, it is absolutely possible. Take my small factory for example. There are not many equipments, but as long as there are suitable materials, general machinery and equipment can be assembled for you. Of course, my factory is mainly for people. There are all kinds of parts, and we have never made a complex complete set of machinery. There are also some small parts, which we generally don’t make.” Zhan Wuya scratched his head, he is not used to standing on the stage like this to receive consultations, “For example All kinds of standard parts, oh—” he realized that many people don’t know what standard parts are, so he explained, “It’s mechanical parts for fastening connections, such as screws, screws, washers, etc. It’s best to use specialized equipment."

"Of course, it is also possible to manufacture these, but it is a little more troublesome. We can make some special machines to manufacture these standard parts.

"There are also various castings, gears, bearings, etc. These are not things that a small machinery factory like ours can manufacture. It involves special equipment, and some require heat treatment and electroplating. I don't know much about this. Buy ready-made pieces directly, or ask someone to process them."

"But gears and bearings are very useful, and if they cannot be manufactured, it means that the equipment manufacturing industry is out of business."

"Then bring special equipment. For gears, you can use a gear hobbing machine. Bearings are more difficult..."

"A complete set of equipment for the bearing factory may cost over ten million."

"Over ten million is a trivial matter, how can you find so many skilled workers to do it?"

"It is still necessary to use the local method. Try to use the existing equipment as much as possible. It is too expensive to invest in professional equipment."

"The material needs a heat treatment furnace. The bearing retainer and mounting balls can be done by hand, and if it is fixed, it can be fixed with a punching machine."

……

Then it entered a more complicated discussion stage. After muttering for a while, the discussion in the industrial group subsided, and a consensus was probably reached on the manufacturing methods and equipment of gears and bearings. Someone began to write a list. Xiao Zishan guessed that it might be one of the equipment lists kind of stuff.

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 punching machines can be replaced. Bring as many knives and grinding wheels as possible. In addition, the machinery factory does not have Milling machines and heat treatment furnaces, all of which need to be brought.”

"If you want to be as complete as possible, you need broaching machines and boring machines, and there should be more lathes." Jiang Ye, who has worked as a lathe for eight years, said, "After all, lathes are the most basic machining equipment."

"How about preparing 8 lathes?"

"Less, 12 units. This thing is very useful."

"What about the forging press? This is also necessary."

……

While the mechanical discussion was going on in full swing, many people started to yawn, but due to the restriction of not being able to leave the venue before the end of the topic, they started their own small group discussion, and the conference room was full of buzzing for a while.

Wang Luobin stood up suddenly, without asking the host's opinion - the industrial group's mechanical engineers completely ignored the conference host - "We still need a small foundry, this must not be forgotten. And we will build engines in the future, This is a necessary condition. In other words, a single-cylinder diesel engine is simply a universal machine: it can plow the land and plant rice seedlings in the fields, drive ships in the water, generate electricity in the mountains, and transport people and goods on the road.”

"Small engines are not a big problem. General agricultural single-cylinder engines can use cast iron. HT250 is better: good shock absorption; casting fluidity is good for easy molding. It is easy to cut during processing."

"When it comes to casting, I think of the problem of mold opening in manufacturing. This is a professional business. You cannot make good products if you have equipment. You must have molds. The equipment required by the modern mold industry is too bad: 3D modeling, electric discharge Processing...it's not easy to handle."

"It's not that exaggerated. What you're talking about is that now, in the past, process designers designed and drawn mold drawings, then machined parts, and finally assembled them by fitters—the level of fitters is very important."

……

Gradually, the mechanical discussion subsided, and the industrial group also used up a lot of paper. It seemed that they were all confident.Wen Desi saw Wang Gong writing there with great interest, and couldn't help worrying whether the purchase order would be too long.

"I'm Ji Siti." A bearded man stood up. Although he had a full beard, his face was baby-faced in the century. "I express my strong protest on behalf of the chemical industry group." Group" these three words deliberately emphasized the tone, "The chemical industry is a very important industrial category, how can it be classified into the industrial group indiscriminately? They are all engaged in machinery and have nothing to do with us What!"

"As for the grouping issue, we will discuss it later. Let me first talk about your views on the chemical industry."

"Three acids and two bases. Our goal is to solve the production of these things.

"Let me first popularize the basic knowledge of chemical industry. 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 still watched his speech with great interest.

"Chemical industry is the industry with the strongest diversity in all industrial fields. The products of the chemical industry are rarely end products, and these products are mainly used by other industrial sectors. For example: sulfuric acid is the fertilizer industry, soda ash It is the glass manufacturing industry, synthetic ammonia is the pharmaceutical and fertilizer industry, etc. As long as we can solve the manufacture of these basic heavy chemical products, we can solve many material manufacturing problems.

"Do you know how much you rely on chemicals in your life? You don't know, that's why you combine chemicals and machinery!" He shook his head, "What a tragedy!"

"Don't express so many emotions, let's talk about chemical engineering."

"Our basic chemical equipment needs a synthetic ammonia and combined alkali production system and a coking chemical system. These two sets of equipment can roughly meet our basic needs, especially the synthetic ammonia equipment."

"What is coking equipment?"

"A coke oven?"

"No, to put it simply, it is a joint manufacturing facility that uses coal tar to manufacture various chemical products. It can manufacture sulfuric acid, phenol, *, dyes, and yes, sulfonamide."

"Sulfa is useful, so we have antibiotics."

"Of course, this output is not very high, but it is usually enough."

"What about synthetic ammonia, for fertilizer?"

"It's very useful to us. In short, without ammonia, we can't produce nitric acid.

"Without nitric acid, we can't make zha medicine

"Of course there is also the fertilizer industry, which is more dependent on synthetic ammonia."

"In addition to complete sets of equipment, some spare chemical equipment should be prepared: such as comprehensive towers, absorption towers, decarbonization towers, rectification towers, saturated hot water towers, various reaction kettles, pressure-resistant pipelines, acid pumps, heaters... I think there must be 500-600 tons of materials to be enough."

"These things, um, can't they be produced by themselves? Our machinery industry is relatively complete."

"Materials." Ji Situ said, "Unless stainless steel, polyethylene and other materials 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 military industry used tanks as reaction towers to make sulfuric acid. And many of the largest local chemical equipment also use these things." Luo Duo came out to speak again.

"I don't know about this. There is no need to use indigenous equipment if you can purchase modern equipment. At least the production efficiency will be improved a lot. Even the production environment is better than the indigenous method. If any of you like to use water tanks to make sulfuric acid, you have to Take care of your teeth."

"I would like to ask, with these devices, can we establish an organic chemical industry?"

"This, I'm afraid it will be difficult." Ji Sixui thought, you really have to look forward to Sichuan, is this organic chemical industry so easy to do.

"Then there will be no nylon and synthetic rubber." Some people are lamenting.

"What do you want nylon for, stockings?" someone teased.

"Black shreds, pork shreds...not one less."

When the atmosphere started to become spoof, Xiao Zishan had no choice but to suppress everyone's creativity and get back to the topic.

"It takes 11 years for rubber to be tapped, but there are many places where rubber is used."

"We don't want to make condoms, why do we have to use rubber."

This remark caused another burst of laughter, and the meeting once again fell into an endless discussion.

Xiao Zishan managed to calm everyone down.

"I think you want to have organic chemical industry because you want plastic." Ji Situ turned to the person who proposed to build organic chemical industry, and the other party nodded. "Although plastic is our most common daily life product, it involves The organic chemistry is so complex that we're unlikely to make it -- it's not just a matter of raw materials. But we can make celluloid and Bakelite."

"Bakelite is useful."

"Bakelite is useful if we're going to build an electrical system, but so is rubber..."

"The discussion on rubber will be explained by the agricultural group later."
