Smart Industrial Empire

() "In the old district, how many beds have been produced for 40 beds?" Yun Fei found Ou Yuanshan who was not in the office but was wandering around in the workshop and asked him.

"During this period, the furnace didn't stop heating for 24 hours, and we only produced the bed of more than 400 lathes. If we want to achieve the minimum production scale of [-] lathes a day that you mentioned, our production capacity will not be able to produce in a short period of time." Reached. Besides, so much production? Can it be sold?" Ou Yuanshan really didn't understand, where did this young boss come from so much confidence.

It has been almost half a month, and Yunfei has been urging the mass production of the bed of these machine tools.Although the follow-up processing has also begun to be produced one after another, the production capacity of the machining workshop is simply unable to process the various castings of more than 20 lathes that are cast every day.

"The production capacity of [-] units per day is something that will happen in half a year. Let's not consider this issue now. In the next six months, we must quickly train those newly recruited molding sand workers." Yun Fei did not give Qu Yuanshan Explain why you have a large backlog of blanks in the factory from the beginning.

For a lathe, it takes at least a month from the time the iron ingot is put into the smelting furnace to the final assembly.If there is no second-hand aging treatment equipment bought by Kamat from Japan, it is possible to normalize and temper these two-three-meter-long bed bodies for artificial aging, even if it takes one year, Jiuyi Heavy Industry's first Even a single lathe cannot go to the market.

The original 9327 factory left not many machine tool beds, only more than 600 in total, and finally sold a lot of them as scrap iron by those prodigal factory managers. After Yun Fei took over, the statistics showed that only More than 200 units.

On the second day after the ignition of the smelting workshop, the mechanical processing workshop began to be officially put into production.

Those machine tool beds with rusty spots on the outside are now in the semi-fine processing workshop built by the original 9327 factory's precision processing workshop equipment and some equipment shipped back from the Soviet Union, waiting in line for those who are many times larger than them Even ten times the gantry milling machine milled off a thick layer of rust on their surface.

"By the way, Xiaoyun, we don't have enough furnaces for aging treatment. One furnace can only process the beds of two lathes at a time, that is, the largest one. It can only process six lathes at a time. We only have four furnaces for heat treatment. , Now we are dealing with a long period of time for aging treatment, do you think we should add some?" Qu Yuanshan, a young man who seems to know everything on the surface, but in fact knows nothing about the boss Yunfei, I could only sigh helplessly in my heart.

If Zhaoyun does not do this, even if one lathe is produced, one can be sold. With the current production capacity of the melting furnace, it will not take long for the thousands of square meters of open space outside the melting workshop to be produced. The bed castings are piled up.

Now more than 400 sets of equipment have already taken up half of the area.

"This is a problem, but let's not be too busy buying equipment right now. We will just make do with the equipment in the factory." Yun Fei still thought about the outdated furnaces that can be found in this era and can be heat treated and aged. I really don't want to add too much.

Although these annealing furnaces, normalizing furnaces, and tempering furnaces are not expensive in this era, because these furnaces are basically the same, the only difference is the heating temperature.A large set is only 30 million, but the efficiency of those equipment is indeed too low, and the production cost is too high.

9327 used to be able to manufacture basically all the equipment he used, but the cost was higher than buying two from outside.In particular, many of the old technicians have retired. Now these workers have not produced these heating furnaces themselves for many years, so at the beginning, Ou Yuanshan just became the workshop director. After reaching the production capacity of [-] units, it was proposed to manufacture some furnace bodies, but Yun Fei denied it.

At that time, Yunfei said that we are no longer the kind of production that does not care about the cost before, and Jiuyi Heavy Industry cannot earn all the money by itself.

In a few years, after the rise of powder metallurgy, various intermediate frequency furnaces and high frequency furnaces will appear, and these old-fashioned melting furnaces will be more perfect at that time.

For the foundry, Yunfei only knows about the hot blast cupola.

There are two air vents on the inside and outside of the heating furnace, and a blower is directly used to ventilate the inside of the furnace body, so that the high temperature zone in the entire heating furnace is extended, and the temperature in the entire furnace is heated faster.

At that time, when these equipments were being transformed, he also proposed his idea to the Soviet engineers, but the Soviet engineers did not have professionals in this field, and until now, they have not achieved any results in theoretical design.

Yun Fei knew that in this era, there were production and sales of such equipment in China, but the price was far higher than these ordinary melting furnaces.The current Jiuyi Heavy Industry does not have any income, and the funds are already tight. The money earned from the talent trade with Kamat has been replaced by the low-cost equipment of the Soviet Union.

Otherwise, with the original 9327 factory not having much heavy equipment, and even many things being produced by hand, it would not even be able to produce ten machine tools a day.

The largest smelting furnace in the smelting workshop can melt seven tons of molten iron at a time. The bed of the 6140 lathe is only a little more than one ton, and one furnace of molten iron is enough for six lathe beds.That smelting furnace is the main production force of the whole workshop. The molten iron melted by other small smelting furnaces is used to pour some small castings such as the bed foot of the lathe and the headstock.

Every day, dozens of tons of iron ingots are turned into molten iron, and then poured into molds made of molding sand to become various parts on the lathe.

The current price of steel is not cheaper than that of later generations, and even rich people may not be able to buy it.If it weren't for Yunfei's factory, it was the 9327 factory of the Ninth Academy, even he would worry about the most basic raw materials.

The major factories in the entire Daba Mountain are not short of the use of steel, even in the most difficult times, because the Dukou Iron and Steel Factory in the land of Bashu will openly supply them.

"Old district, now you produce, you must strictly follow the process. You know, this set of processes is a fusion of your original production process and the Soviet machine tool production process. Although it may not be the best, but From the current situation, it should be the most suitable." After wandering around the smelting workshop, Yun Fei was ready to go to the machining workshop.

"Xiaoyun, let me say, since ten or twenty hours of artificial aging can exceed the effect of one year's natural aging, do we need to carry out artificial aging twice?" Yun Fei didn't say that the craftsmanship was fine, When it comes to the current craftsmanship, Qu Yuanshan is fire.

Originally, the equipment for heat treatment was not enough, because the equipment they produced in the past was not artificially aged.When they produced machine tools, the plan was issued three or even five years ago.That is to say, the lathes cast this year will generally be neatly placed in the open space outside the workshop, and will be exposed to the wind, sun, and rain, and will not be processed until three years later.

After several years of natural aging, the internal stress of these parts of the machine tool will gradually disappear under the wind and sun and its own gravity, followed by the deformation of the bed.At that time, as long as these deformed parts are processed, the stress remaining inside the machine bed will not be much left. After a short stress-relief annealing before the fine machining, the internal stress of the machine tool will still remain. There will be no more stress.

The structure of the machine tool bed produced in that way will become very stable.

Now Jiuyi Heavy Industry produces machine tools, not following the original 9327 rules that have been used for decades.Ou Yuanshan also knew that Yun Fei, the private boss, would not be able to bear the natural aging of these machine bed for at least one year.

In that case, it is estimated that even if Yunfei has hundreds of millions of funds, he will not be able to afford it.Based on the current wages of the entire Jiuyi Heavy Industry, the entire factory, with more than 1000 people, costs several million in wages alone every year.In particular, the weight of the bed of these machine tools is in tonnage units. Taking the current production volume as an example, there are an average of [-] sets per day, and [-] to [-] sets of equipment are needed a year. This requires [-] to [-] tons of steel!That's tens of millions!

But in any case, there is no need to do a second aging treatment that seems like a useless effort when the equipment is not enough?The second artificial aging took up a lot of the already low production capacity.

"In the old district, since we have produced, not to mention producing the best, but at least we have to produce the highest level of machine tools that we can achieve. On the surface, the second artificial aging is not very useful, because at that time the internal parts of the casting The stress has not been much after the first aging period. The remaining stress is just a small amount of stress produced by the processing engineering." Yunfei knew that, for this, Qu Yuanshan, the workshop director of the smelting workshop, knew better than himself. But what he is going to say next needs this to pave the way.

"Although the lathes we produce are the most common lathes, the level of precision is not high. But in the old districts, do you understand why so many domestic machine tool manufacturers are facing difficulties now? Those large machinery factories are willing to Going to buy old machine tools from bankrupt machinery factories, and unwilling to buy new equipment produced by those machine tool factories? Do you know why?" Seeing Ou Yuanshan staring at him in confusion, Yun Fei suddenly sold A hurdle.

Ou Yuanshan was about to get impatient when he heard a lot of nonsense from Yun Fei. Can he, a college student who has worked in smelting and heat treatment all his life, still not understand what Yun Fei said, stress and so on?Later, when he heard Yun Fei talk about the current difficulties faced by the entire domestic machine tool industry, he listened patiently, but he didn't expect that this kid would actually play tricks in front of him.
