Chapter 38 A Trip to the Ministry of Machinery

Li Zhao could only smile bitterly at this time, he originally wanted to consult Chief Engineer Xia'an, after all, he had just joined the work, and he was not very clear about the overall situation now, and an old technician like Chief Engineer An could give better advice, but he really didn't expect that he was directly dragged to the Ministry of Industry before he finished talking about things.

Sitting in the car, Li Zhao took out the last drawing in his bag, he thought about it for a long time yesterday, and he didn't think about what the main product of the rolling mill was, and when he was cleaning up the drawings today, he accidentally found a drawing, which was a drawing drawn three years ago, which reminded him of a more interesting thing, a non-powered exoskeleton.

Hand this drawing to Chief Engineer An and let him take a look at it first, this drawing was the work of an exoskeleton enthusiast in Li Zhao's previous life, and he took it to their factory for processing. They used high-strength carbon fiber at that time, which was lighter, to put it bluntly, to provide a support for the human body in the process of action, and the weight was directly transmitted to the ground, rather than acting on the human body, and then transmitted to the ground, which could also provide a certain boost to the exercise process.

"To achieve such an effect, doesn't this mean that a person can carry forty or fifty percent more weight?" After reading Mr. An, he was also a little skeptical, because it did not provide motivation. Hearing this, Director Yang also looked at it, and Chief Engineer An handed Li Zhao's drawings to Director Yang.

"Can you do this?" After reading it, Director Yang asked, if this is to equip the troops, it can basically allow the soldiers to bring hundreds of more rounds of ammunition, he came down from the battlefield, and knows the importance of material carrying, especially for mountainous and plateau areas, using exoskeletons, each time you can send up forty or fifty percent more materials, which is of great significance, and may completely change the situation.

"This also has disadvantages, if it is made of metal, unless it is made of aluminum alloy, it is a bit heavy with steel, and the strength of other materials is a problem, I don't know how FRP is, but you can also try it to see how the effect is. These data are all theoretically calculated, and we can try them after processing. ”

Li Zhao is not sure about the effect, when processing, the enthusiast said that it can save sixty or seventy percent of the effort, which is equivalent to a person who can only carry 30 kilograms, can directly carry more than 40 kilograms, and the most important thing is that there are hanging points on the exoskeleton, which can directly fix some things on the exoskeleton and free your hands.

"How many good things do you still haven't taken out, this one surprises me more than the other?" Director Yang is also very uncalm now, which is more amazing than the other.

"Really, don't you think of anything when you look at the electroslag remelting furnace?" Seeing the puzzled look of the two, Li Zhao prompted: "It can produce high-performance alloy steel, and refined metals to remove impurities." Speaking of which, Li Zhao understood that they were all in civilian use now, forgetting the military aspect, so he had to prompt: "Artillery!" ”

Hearing this word, the two immediately understood, and Director Yang couldn't help asking, "How much performance can be improved?" ”

"It is said that electroslag remelting furnaces are now used in the West to refine metals, and at the same time, there are self-tightening of the body tube and chrome plating on the inner wall, if they are implemented, then the service life of the same gun will be at least doubled, and it can withstand greater boring."

Seeing that the two of them were listening carefully, Li Zhao talked about the method of self-tightening that he saw in his previous life, and chrome plating was Li Zhao's forte, and after speaking, the two of them were also a little numb.

But what is even more helpless is Li Zhao, these things are simple, but it is very difficult to really implement, just say that he took out the machine tool drawings, as long as the electroslag remelting furnace is built, the problem is not big, but what should I do with the accuracy of the parts? According to Li Zhao's current estimate, the equipment of the rolling mill needs to be upgraded at least twice to meet the accuracy requirements.

Seeing Director Yang with a happy face, Li Zhao sighed in his heart, this matter is making trouble, I just wanted to see what project to do next, thinking that I had drawn a lot of drawings, and wanted Chief Engineer An to help the staff to see what was suitable, but now it is completely beyond the mastery, which is basically preparing for a major mechanical upgrade. Thinking about the difficulty of upgrading, Li Zhao only sighed, the processing accuracy of the current rolling mill can barely reach the level of a few wires after cooperating with labor, and the drawings that Li Zhao took out want to produce, at least a few microns.

And how can it be so simple to upgrade the equipment, you need to design the next generation of products based on this generation of equipment, cooperate with labor, and then produce parts, install and calibrate, use, if it does not meet the requirements, continue to produce until it is reached. With a new generation of products, expand the scale based on this product, and then design the next generation of products based on this generation, so that the progress can be completed.

Li Zhao took out the machine tool design drawing is a product that needs at least two upgrades to complete, he used the classic model of the seventies and eighties, but also upgraded the product, after all, he is ready to build the product after thirty or forty years, and the accuracy is not enough to produce it is just a decoration.

Of course, these are not meaningless, but the design indicators are relatively high, which can provide goals for the current production, know the direction of progress, and not be blinded, and do not know where to work, but if you want to create it directly, it is impossible now.

Thinking of this, Li Zhao also had to remind Director Yang: "Director Yang, my machine tool design is not the current production accuracy can be achieved, with materials, it is possible to produce at least two rounds of precision improvement?" And each round of accuracy improvement requires many tests, which is not something that can be solved now. Li Zhao was also afraid that Director Yang would be scolded in the ministry, so don't think about it in the end.

Seeing Li Zhao's helpless expression, Director Yang was also happy in his heart, and said: "Do you think our level is only like our rolling mill?" Our rolling mill is mainly civilian, and our focus is not on the fitter, and the products in the fitter workshop are only for the relevant units to do matching, your drawings we can't manufacture, it doesn't mean that other units can't. Speaking of this, Director Yang smiled mysteriously.

Then he said: "Then you will know, although I don't know much about machinery, but I still understand the parameters marked on your drawings, if your designs pass the review, then the production should not be a big problem." ”

Hearing this, Li Zhao also didn't believe it, if it could be produced, how could it be that such a product would be produced in the seventies? Moreover, Li Zhao has further optimized, and it can be said that the machining accuracy has been improved. In fact, this is Li Zhao's own thoughts, it is not that there is no high-precision equipment in the country, but due to the weak industrial base in China, the relevant staff are also inexperienced, not only inexperienced, but also no one to bring, and when the big brother supported, he brought a wave, but soon withdrew, and the country groped for itself, so it didn't delay time?

Li Zhao looked at the rolling mill on the spot, and felt that the rolling mill only had this level, and the level of other places could also be imagined, after all, the rolling mill was also a big factory. This makes Li Zhao misestimate the real level of the country, some high-precision machine tools are still available, but you don't have an excellent design, it's also useless.

Hearing Director Yang's words, although Li Zhao still has doubts, but he also put down a big stone in his heart, if Li Zhao's designs are realized, then he can take products out on a large scale, and the development speed will definitely be accelerated.

Saying that, the group came to the Ministry of Industry, came to the leader's office, and everyone sat down, Director Yang hurriedly handed a bunch of drawings to the leader, and asked him to look at the drawings first. "You guys are here with a meal, you're going to let me invite you, this time you have made a great contribution, and you should eat me." The leader said with a smile.

Director Yang also said at this time: "The leader is really not to eat you, it is Li Zhao who has made a big deal again, we can't make up our minds, so we can only ask the leader for you." ”

The first thing the leader picked up was the electroslag remelting furnace, looking at the steelmaking furnace, the leader asked suspiciously: "Now that the economy is in difficulty, don't you want to postpone the development of the steelmaking furnace, why do you propose a new steelmaking furnace, and the scale is a little small?" The leader was also a little puzzled, after all, he still didn't know much about cutting-edge technology.

"Didn't you all say that the bigger the steelmaking furnace, the more advantageous, which is only one-tenth of the capacity of the oxygen top blowing converter you mentioned earlier?" The leader asked suspiciously.

At this time, everyone looked at Li Zhao, and Li Zhao was also helpless, this was to let himself explain. So Li Zhao talked about the principle and function of the electroslag remelting furnace, the formula of alloy steel and the use of the electroslag remelting furnace that Chief Engineer He'an had talked about, especially emphasizing the role of artillery. Of course, during this period, he also talked about some of the methods used in the production of artillery decades later, mainly electroslag remelting, self-tightening of the body tube and chrome plating.
