Early the next morning, Li Zhao got up to cook, made an appointment with his family today, and came over early today to go to work in the rolling mill, ate at his place, and then went to the rolling mill to report together. Breakfast is very simple, just wotou, corn porridge, and some pickles, this is no way, at this time Li Zhao is too poor, and embarrassed to ask the family for money, although he has issued food and bills, but there is no money.

Soon everyone came, the team led by his brother Li Yu came in a donkey cart, and after eating Li Yu went back, Li Zhao took them to the rolling mill and went to his office to rest first. I went to sign in by myself, and after saying hello to Chief Engineer An, I took them to go through the process, it should be Director Yang who said hello, and things went well.

The younger sister's name is Wang Jun, he arranged to work as a draughtsman in the technical department, and he can take care of it, the other three, two of the young in the village, went to the fitter workshop as an apprentice, and the second brother-in-law's family, who was older, was actually interested in driving and went to the team.

Although his brother still has a year to graduate from the secondary school, but he will be fine, directly to the affiliated hospital for internship, they all have dormitories, but their brother has to take care of more, lead them to report, go through various procedures, arrange dormitories, all the arrangements are completed, it took two or three hours, they also went to rest, ready to go to work the next day.

After coming back, he took the drawings and his own notebook to find the chief engineer of An, this chief engineer of Hoi An is nothing, he is an expert in steel smelting, presided over the construction of the oxygen side blowing converter, and now the problems he encountered, just ask him for advice.

"Chief Engineer An, do you have time now?" When I got to the office, I asked if there was the best time, after all, Chief Engineer An now almost has to stare at the processing of steel profiles, which will be put into production soon, and technical problems will arise at any time, and they can be solved at any time, Li Zhao estimates that it will take a lot of time.

After receiving a positive reply, Li Zhao first took out the drawings of agricultural machinery and non-powered pumping device from his bag, gave them to Chief Engineer An, and explained to him: "I originally wanted to engage in bicycle production in the factory after the agricultural machinery was put into production, but I thought about it yesterday, it was too expensive and had little practical significance, and it was of limited use to the improvement of our national strength." This is what I originally wanted to design, or replace the bicycle wheels with cast iron wheels, which have not yet started production, and now we are starting to produce this, so that we can catch up with wheat planting. ”

Although there are cocoons for wheat sowing now, the cocoons used are too cumbersome, and the three-legged cocoons can only be operated by at least six or seven people if there are no livestock to pull them, and the use of cocoons also requires a very experienced master to drive, otherwise the seeds cannot be sown. And the kind that is now put into production is cheaper than this one and is more suitable for sowing corn, while this one requires sprockets and chain drives, and is more suitable for sowing wheat.

"yes, bikes aren't a necessity right now, people don't have enough to eat right now, and bikes like bikes can slow down plans. Just like why you get so much attention to agricultural machinery, it is not an effective way to improve sowing efficiency and enhance national strength, just say that many farms are not equipped with tractors, and your agricultural machinery can make their sowing area several times. And your unpowered pumping device is also quite interesting, the principle is very simple, have you tried it? Chief Engineer An also appreciated Li Zhao's changes.

In fact, Li Zhao thought about it, how could there be no masters in the factory, he wanted to engage in bicycles, they all understood, but they didn't expect Li Zhao to give up in the end.

"After verifying, I went home this time and found that it was not bad, so I took it." After saying this, Li Zhao began to consult: "It's just that I can't make up my mind about what project to do next in the past two days, and now I feel that there are too many places that need to be improved in the rolling mill, and I want to see your opinions." ”

"I want to upgrade our machine tools now, but the upgrade will involve high-performance steel and better tools, so I wonder if I can build an electroslag remelting furnace." Then Li Zhao introduced the electroslag remelting furnace and Chief Engineer An, and took out the drawings of the electroslag remelting furnace that had been drawn long ago, and attached more than a dozen alloy steel formulas and performance parameters.

What he took out was a three-ton level, which was also used by the machinery factory in his previous life, which was a mature design, and the various consumables and parameters needed in it were very detailed, and it belonged to the kind of design that could be effective immediately as long as it was built, and the construction price was not too expensive.

The main reason is that the power consumption is too great, and one ton of steel requires four or five hundred thousand degrees of electricity. The alloy steel is mainly the alloy steel of common raw materials, and the rare earth ones have not been taken out, and those are now used a bit of a waste, just these formulas, if the performance can be achieved, then it will be directly in the alloy steel for thirty or forty years.

After reading the drawings and alloy steel formula parameters, Chief Engineer An couldn't calm down, and said excitedly: "These are all true? "Don't blame him for being excited, these are really amazing, if they are really as the parameters provided by Li Zhao, these many things can be directly stepped forward in the next step.

"It's true, without these things to guarantee, I don't dare to say that I can transform the machine tool. You also know, just say the speed of the machine tool, increasing the speed can effectively improve the processing speed, but the speed increases, the requirements for parts are higher, requiring higher precision, higher structural strength, there is no excellent steel, increasing the speed is a castle in the air. Li Zhao replied, this is indeed the case, many key parts, if there is no alloy steel, it is really not playable, the strength of the parts can not be reached, the speed is fast, and the equipment will be broken in a short time.

The dozen or so alloy steel formulas selected by Li Zhao are the most commonly used ones after 60 years, and with these, basically all industries can be covered, and the overall level of cutting-edge alloys in the West after 20 years and advanced level after 30 years. And Li Zhao is more familiar with the processing of these alloys, and these are the metals he uses the most.

At this time, where can Chief Engineer An still sit still, this must be done, and it must be done by smashing pots and selling iron. Whether it is Li Zhao's machine tool improvement, or the current steel profile processing equipment, etc., can greatly improve the performance, it is really a bit of a big material gap, although limited by the times, some designs are very outdated, but after the material performance goes up, many design parameters can be relaxed, and the performance of the equipment can be greatly improved.

Chief Engineer An directly took Li Zhao to Director Yang's office, and when he got there, he didn't care about anything, and directly put the drawings of the electroslag remelting furnace and the alloy steel formula and performance parameter table in front of Director Yang, and said: "Li Zhao's project must be carried out, and it must be done by smashing the pot and selling iron!" Then Chief Engineer An talked to Director Yang about the benefits after the completion of the project.

"Can it really be such a big improvement?" Director Yang is also a little unconvinced, after all, according to this statement, the improvement is too great, and it can be said that the performance has increased exponentially.

Seeing this, Li Zhao took out the machine tool drawings that he had already drawn, these are all painted by Li Zhao before, there are hundreds, all of them are bound, they are mature products in the seventies and eighties, and Li Zhao has also optimized according to new materials, these machine tools can basically be said to be the apex of non-CNC machine tools, and the machining accuracy is designed at the level of 0.5 wire, which is basically an accuracy beyond the reach of eight-level fitters.

Including turning, milling, planing, grinding, boring, drilling, drawing, forging, hydraulic press, etc., the drawings are more detailed, and the main components are drawn. Basically, as long as the materials are in place and the machining accuracy is upgraded twice, they can be realized. Of course, Li Zhao took out only the representative ones of all machine tool types, and some of the machine tools designed for special needs he had not touched, and it was not clear, but with these, those are no longer a problem.

Looking at the drawings that Li Zhao took out, Chief Engineer An and Director Yang were wide-eyed, it was too amazing, seeing the reaction of the two, Li Zhao didn't understand the seriousness of the matter, but he was really anxious, if these can be achieved, his goal can take a big step, but it can't be achieved.

"These are all drawn by me when I was in college, and as long as the steel can keep up, our factory only needs to upgrade the machine tools twice to produce these machine tools." Li Zhao said confidently.

At this time, Director Yang took out a cigarette, distributed it to Chief Engineer An, lit it himself, and smoked hard, his heart could not be calm. "Secretary Wu, arrange the car immediately, I have an emergency!" Then he turned his head to Li Zhao and said, "It's done, since the performance is so good, let's do a big one." Next, Director Yang took Li Zhao and Chief Engineer An to the Machinery Department.
