Intelligent Industrial Empire

"In the old district, how much of the 40-bed bed has been produced?" Yun Fei asked him when he found Qu Yuanshan who was not staying in the office but staying in the workshop.

"During this period, the furnace has not stopped heating for 24 hours, and it has only produced more than 400 lathe beds. If you want to achieve the minimum production scale of 50 units per day, our production capacity will be within a short period of time. It can't be achieved at all. Besides, so much production? Can it be sold?" Ou Yuanshan really didn't understand how this young boss had such confidence.

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

"The production capacity of 50 units per day is something that will be done in half a year. Now we don't consider this issue. Within this half a year, those newly recruited sand workers can be trained quickly." Yun Fei did not give Ou Yuanshan Explain why you have a large backlog of blanks in the factory at the beginning.

For a lathe, it takes at least one month from the time the iron ingot is put into the melting furnace to the final assembly.If there is no second-hand aging treatment equipment bought by Kmart from Japan, it can normalize and temper these two-to-three-meter-long bed, even if it is a year, the first machine of Jiuyi Heavy Industry. Lathes cannot go to the market either.

There were not many machine tools left by the original 9327 factory, and there were only more than 600 machines in total. In the end, they were sold as scrap by those prodigal factory managers. After Yunfei took over, according to statistics, there were only More than two hundred under.

On the second day after the smelting workshop was ignited and production started, the mechanical processing workshop also officially started production.

Those rusty machine beds on the outside are now in the semi-finishing workshop built with the equipment of the 9327 factory finishing workshop and some equipment shipped back from the Soviet Union, waiting in line for those that are much larger than they are several times larger. Even a ten-fold gantry milling machine milled away a thick layer of rust on their surface.

"By the way, Xiaoyun, our aging treatment furnace is not enough. One furnace can only handle two lathe beds at a time. The largest one can only handle six at a time. We only have four sets of furnaces for heat treatment. Now we are dealing with a long time for aging treatment, do you think you can add some?" To the boss of Yun Fei, Ou Yuanshan seems to understand everything on the surface, but in fact he does not understand anything. I can only sigh helplessly in my heart.

If this is the case, even if one lathe is produced, one can be sold. With the current capacity of the smelting furnace, it will not be long before the thousands of square meters of open space outside the smelting workshop will be produced. The castings of the bed are full.

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

"This is a problem, but let's not worry about adding equipment for now. Let's just use the equipment in the factory." For those aging furnaces that can be found in this era that can be heat treated and aging, Yun Fei I really don't want to buy 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 that the heating temperature is different.A large set is only two to three million, but the efficiency of those equipment is indeed too low and the production cost is too high.

9327 turned out that basically all the equipment I used could be manufactured by myself, but the cost was higher than buying two outside.Especially since many of the old technicians have already retired. Now these workers have not produced these heating furnaces by themselves for many years. So at the beginning, Ou Yuanshan just became the workshop director. When he heard that Yun Fei planned to have them within a year After reaching the production capacity of 50 units per day, it was proposed to manufacture some furnace bodies, but this was denied by Yunfei.

At that time, Yunfei said that we are no longer the previous production at no cost, and Jiuyi Heavy Industry cannot make all the money on its own.

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

For the foundry workshop, all Yun Fei knew was the hot air cupola.

There is a connecting vent on the inside and outside of the heating furnace, and a blower is used to ventilate the inside of the furnace body directly, which makes the high temperature zone inside the whole heating furnace prolong, and at the same time makes the temperature in the whole furnace heat up faster.

At that time, while carrying out these equipment transformations, he also put forward his ideas to the Soviet engineers. The Soviet engineers did not have professionals in this area, and until now, they have not achieved any results in theoretical design.

Yun Fei knows that in this era, this equipment is produced and sold in China, but the price far exceeds these ordinary smelting furnaces.The current Jiuyi Heavy Industry does not have any money income. Funds are already tight. The money earned from the talent trade with Kamath has been replaced by the low-cost equipment of the Soviet Union.

Otherwise, there are not many heavy equipment of the original 9327 factory, and even many things are purely manual production capacity, and even ten machine tools a day can not be produced.

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

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

The current steel price is no cheaper than later generations, and even money may not be able to buy it.If it weren't for Yunfei's factory, the original 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 indispensable for the use of steel, even in the most difficult times, because the Dukou Steel Plant in Bashu will openly supply them.

"In the old district, now you produce in strict accordance with the craftsmanship. You know, this craft is a combination of your original production craftsmanship and the Soviet machine tool production craftsmanship. Although it may not be the best, but Under the current situation, it seems that it should be the most appropriate.” After Yunfei strolled around in the smelting workshop, he was ready to go to the machining workshop.

"Xiao Yun, I said, since more than ten or twenty hours of artificial aging can exceed the natural aging effect of one year, do we need to perform two artificial aging?" Yun Fei said that the craftsmanship is okay. When it comes to current craftsmanship, Ou Yuanshan is like fire.

Originally, the equipment for heat treatment was not enough, because the equipment they produced before was not artificially aged.When they produced machine tools, their plans were issued three or even five years ago.That is to say, the bed cast this year will generally be placed neatly on the open space outside the workshop, let the wind blow, 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, and the deformation of the bed will follow.At that time, as long as these deformed parts are processed, the stress remaining inside the machine bed will not be much. After a short time stress relief annealing is performed before finishing, the inside of the machine tool will still remain The stress will not be much.

The structure of the machine bed produced in that way becomes very stable.

Now that Jiuyi Heavy Industries produces machine tools, it does not follow the rules of the original 9327 that has been used for decades.Ou Yuanshan also knew that if these machine tools were allowed to undergo natural aging for at least one year, Yunfei, the private boss, simply couldn't afford it.

In that case, it is estimated that Yunfei will not be able to afford it even if it has hundreds of millions of funds.Calculated on the basis of the wages of the entire Jiuyi Heavy Industry, the entire factory, with more than 1,000 employees, will have to pay several million each year.In particular, the weight of the bed of these machine tools is in tonnage units. Take the current production volume, with an average of 20 units per day, seven or eight thousand equipment a year, which requires two to three million tons of steel!That would cost tens of millions!

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

"In the old area, since we have produced it, we don’t say the best production, 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 of little use, because at that time the internal casting The stress has not been much after the first aging. The remaining stress is just a small amount of stress generated by the processing engineering." Yun Fei knows this, the workshop director of the smelting workshop Ou Yuanshan understands better than himself. But what he wants to say next needs this to pave the way.

"Although the lathes we produce are just the most common lathes, the precision is not high. But do you understand why so many domestic machine tool manufacturers are facing difficulties? Those large machinery factories are willing to go Buying old machine tools from those bankrupt machinery factories, and reluctant to buy new equipment produced by those machine tools production factories? Do you know why?" Yun Fei saw Ou Yuanshan staring at himself with a puzzled face and suddenly sold one. Close.

Originally, Ou Yuanshan heard a lot of nonsense from Yun Fei, and was about to get impatient. What Yun Fei said, stress or something, he, a college student who has been working in smelting and heat treatment all his life, can he still not know?Later, when Yun Fei heard about the plight of the entire domestic machine tool industry, he listened patiently, but he didn't expect that this kid would be sold out in front of him.
