After confirming that the drawings were really effective, the leaders also began to coordinate with the military industry department for this joint research, first of all, it must be the construction of an electroslag remelting furnace, and the military industry must invest a part of it. Now the industrial system is also very difficult, just like the rolling mill, which was originally ready to launch the oxygen top blowing converter, but later it was cut because of financial problems, and basically it will not be considered for a year or two.

This time, the electroslag remelting furnace must be very widely used in the military industry, if you can get the name of joint research, then you will definitely be able to get some financial support, then the Ministry of Machinery will be more relaxed. And looking at the meaning of the military industry, the intention to build a large scale is of course a good thing, and it is even more good for the rolling mill, but the investment problem is even greater.

At this time, the leader asked Li Zhao: "What is the approximate cost of your three-ton electroslag remelting furnace, and what is the operating cost per ton of steel after operation?" ”

Taking out the electroslag remelting furnace, Li Zhao roughly calculated the price, so he immediately replied: "In terms of price, the three-ton one is about 70,000 or 80,000 yuan, and the ten-ton one is about 11,000 or 20,000 yuan." This needs to be calculated by the construction department after submitting the design plan. The operating expenses are relatively high, because the power consumption is too large, plus other consumables, the production of one ton of alloy steel, not counting the cost of the steel itself, the cost will be about 300 yuan. And the cost of steel itself will increase accordingly due to the addition of precious metals, and the most expensive is estimated to increase the price per ton by six or seven times. ”

In this era, the price of steel has not been liberalized, so the price is generally regulated by the state, and now it is generally implemented more than 1,000 tons, which should be low, after all, the industrial capacity is here, and the production cost cannot be reduced. And alloy steel due to the problem of precious metals, the price may break through the sky.

After all, the cooperation between the two sides is not a trivial matter, and the two sides need to sit down and have a good talk. After these people who came here today go back to report, they will contact again to determine how to talk. At this time, everyone basically finished talking, and Li Zhao also put away the drawings, these drawings cannot flow out now, and they will be issued in the form of official documents in the future, and the drawings will not flow into other channels. Of course, Li Zhao estimated that it would be difficult for Li Zhao to take these drawings away today, and they would basically stay in the Ministry of Machinery, and then in his hands, they would only be copied and issued by the Ministry of Machinery.

After this talk, the group walked to the conference room of the machine tool seminar, if it turns out that those drawings can be realized, then the final production is likely to need the assistance of the military industry. After all, there are some equipment that ordinary factories do not have, and the military industry is definitely a big customer, and they will purchase a large number of equipment after it is produced, so they will participate in the discussion together.

When I returned to the conference room here, I found that it had been divided into more than a dozen small groups, and I asked Director Yang to find out that these people were studying what they were best at, and were now checking the design parameters.

Seeing Li Zhao and his entourage return to the conference room, everyone also understood that this was the matter of the military industry, everyone sat down, and Li Zhao also came to sit next to Director Yang, he was a little afraid of being scolded. The parameters of this batch of machine tools designed by him are quite high, although they are improved on the classics of the seventies and eighties, but the design indicators are still higher than those, and it is only the early sixties, and the possibility of realization is even lower.

When everyone is done, the leader looks at everyone and speaks first: "How about these designs?" ”

At this time, everyone looked at a person sitting in the middle of everyone, this person Li Zhao didn't know, but seeing that everyone looked at him, it was obviously a master. He is very old, about sixty or seventy years old, and his hair is mostly gray, but he looks in good spirits.

Seeing that everyone was looking at himself, he also said first: "Just now everyone has checked, the index is very high, the whole machine design is very mature in my opinion, the design of all parts is very ingenious, the specifications of the parts are very compact, if you only talk about the design, this is a very mature set of machine tools." ”

After saying this, the old man looked at everyone and found that everyone nodded yes, and then continued: "But according to the calculation we just checked, we found that there are a few points that are difficult to solve, if these cannot be solved, then this set of designs can only be used as a reference." Everyone also nodded solemnly.

At this time, the old man then asked, "Leader, who designed it at this time, can you let us meet it?" I see you're with Xiao An, I asked Xiao An, he said it's not him, you don't hide people, this design is very good, but the implementation is difficult, we need to talk to him face to face to see if there is a little possibility of implementation. ”

When the leader heard that the design was very good, most of the stones in his heart were put down, but when he heard that there were difficulties, he knew that Li Zhao had already said something. The people on the military side were still a little dazed when they heard it, so they borrowed the drawings from the people next to them, and after reading them, they felt a little sluggish, and they were really surprised by the design parameters.

At this time, the leader also slipped Li Zhaoti out and said: "Don't doubt it, it was designed by this little guy, and everyone has heard of the agricultural machinery in the newspaper in front of you, right?" It's also from this little guy.

Seeing the incredible look of everyone, the leader continued: "This time this little guy saw that the equipment of their rolling mill was too backward, and felt that there were too many things that needed to be improved, and he didn't know where to start, so he took a bunch of designs to find them An Zonggong Volume, and then their factory director and General An were scared by him, so he brought people to me and invited someone to come to the trial." Now I will hand him over to you, and if you have any questions, you can ask him, and try to take out as many of his things as possible. ”

After speaking, the leader called Li Zhao up, asked him to stand in front of the blackboard, and asked everyone to ask questions. Or the old gentleman, first asked: "According to the calculation, the strength requirements of your parts are very high, how are you going to solve it, as far as I know, there is no kind of steel that meets the requirements of your design, how are you going to solve it?" ”

Li Zhao also looked at the leader at this time and asked, "Can I say?" After receiving an affirmative answer, Li Zhao popularized the electroslag remelting furnace and the alloy steel formula to the audience, which was the fifth time today. When they heard this, all the people understood.

At this time, the old man asked again: "So you are very sure about alloy steel?" We also have these studies, but the current progress is not up to these requirements, when will we be able to come up with the finished product? ”

Hearing the old man's words, Li Zhao could only reply: "These have not yet become projects, I was just looking for us today to see what the most urgent problem to be solved in our rolling mill is, but I just brought these drawings to him for reference to see which directions are suitable for our development, and I was a little confused when I was pulled here." Speaking of this, Li Zhao was also a little embarrassed.

The old man then asked: "There is a way, then it can be regarded as a solution, so how are you going to solve the problem of machining accuracy?" The current machining accuracy is much worse. ”

"This is also what I was worried about, so my original plan was to try to produce these machines after two rounds of precision upgrades in our rolling mill, but our factory director said that the ministry might be able to solve it, so he brought me here." Li Zhao was also helpless, so he could only tell the truth.

At this time, the people in the military industry department replied and said: "We can achieve this accuracy." We have several high-precision machine tools imported from Big Brother that can achieve this machining accuracy. Everyone also looked at them in unison, and Director Yang smiled at Li Zhao, which meant that it was like saying, I knew it was so.

At this time, many people are a little angry in their hearts, is it really good to put things in them, put them in us, we have already upgraded the equipment, but there is no way, it seems that there are very few things, but as long as these designs can come out with a set, then the follow-up is endless.

Then the old man continued to ask: "This is also solved, the last problem, what to do with the assembly, I looked at your designs, basically the gap between the assembly is very small, it can almost be said that it is tightly fitted, how to achieve this effect." ”

Li Zhao was also a little helpless, he didn't expect this to become a problem, but it may be true, how can anyone carry out such a precise assembly now, so he replied: "Low temperature assembly, ensure that the ambient temperature is very low when assembling, so that when used at room temperature, it can effectively reduce the matching gap of parts, and greatly reduce the vibration of machinery and the error during operation." ”
