Chapter 178

"In the old area, how many 40 beds have been produced?" Yunfei asked Qu Yuanshan, who didn't stay in the office but was wandering around the workshop site.

"During this period, the furnace has not stopped heating for 24 hours, and it can only produce the beds of more than 400 lathes. If we want to achieve the scale of producing at least 50 lathes a day, our production capacity can not be achieved in a short time. Besides, so much production? Can you sell it? " Qu Yuanshan really doesn't understand that this young boss has such great confidence.

It's almost half a month. Yunfei has been urging the mass production of these machine tool beds. Although the subsequent processing has also begun to produce one after another, the capacity of the machining workshop simply cannot process all kinds of castings of more than 20 lathes cast every day.

"The production capacity of 50 units a day will be six months later. Now we don't consider this problem. In the past six months, we have to train those newly recruited molding Sanders quickly." Yunfei didn't explain to Qu Yuanshan why he overstocked a large number of blanks in the factory at the beginning.

It takes at least a month for a lathe to be assembled from the time when the ingot is put into the smelting furnace. Without the second-hand aging treatment equipment bought by camart from Japan, these beds up to two or three meters can be normalized and tempered. These artificial aging can not go to the market even in a year.

There were not many machine tool beds left by the original 9327 factory, and there were only more than 600 in total. Finally, many of them were sold as scrap iron by those black sheep factory directors. After Yun Fei took over, there were only more than 200 left.

On the second day of ignition production in the smelting workshop, the machining workshop began to be officially put into production.

Those machine tool beds with rust outside are now in the semi finishing workshop built by the finishing workshop equipment of factory 9327 and some equipment shipped back from the Soviet Union, waiting in line for the gantry milling machines that are many times or even ten times larger than them to mill off a thick layer of rust on their surface.

"By the way, Xiao Yun, our aging treatment furnace is not enough. One furnace can only handle the bed of two lathes at a time, that is, the largest one can only handle six at a time. We only have four sets of furnaces for heat treatment. Now we deal with aging treatment for a long time. Do you think we can add some?" Qu Yuanshan can only sigh helplessly for the young man who seems to know everything about Yunfei, but actually doesn't know anything.

If Zhao Yun doesn't do this, even if a lathe is produced, one can be sold. With the current smelting furnace capacity, it won't be long before the thousands of square meters of open space outside the smelting workshop will be filled with bed castings.

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

"That's a problem, but let's not rush to buy equipment now. Make do with the equipment in the factory. " Yunfei really doesn't want to buy too many aging furnaces that can be found in this era and can be heat treated and aging treated.

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 200 or 300 thousand, but the efficiency of those equipment is really too low and the production cost is too high.

9327 the original equipment used by ourselves can basically be manufactured by ourselves, but the cost is higher than buying two outside. In particular, many of the old technicians have retired. Now these workers have not produced these heating furnaces for many years, so at the beginning, Qu Yuanshan just became the workshop director. When he heard that Yunfei planned to reach the production capacity of 50 units per day within one year, he proposed to manufacture some furnace bodies, but Yunfei denied it.

At that time, Yun Fei said that we are no longer the production regardless of cost in the past. Moreover, Jiuyi heavy industry can't make all the money by itself.

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

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

There is a vent inside and outside the heating furnace. A blower is directly used to ventilate the inside of the furnace body, so as to prolong the high-temperature area in the whole heating furnace and heat the temperature in the whole furnace faster.

At that time, during the transformation of these equipment, he also put forward his idea to those engineers in the Soviet Union, but the Soviet engineers did not have professionals in this field, and up to now, they have not achieved any results in theoretical design.

Yun Fei knows that in this era, such equipment is produced and sold in China, but the price is far higher than these ordinary smelting furnaces. Today's Jiuyi heavy industry has no income of any money, and the funds are already tight. The money earned from talent trade with Kmart has been replaced by those low-cost equipment in the Soviet Union.

Otherwise, there are not many heavy equipment in the original 9327 plant, and even many things are produced purely manually, which can not even produce ten machine tools a day.

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

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. Even if you have money, you may not be able to buy it. If it weren't for Yunfei's factory and the original 9327 factory of the Ninth Hospital, even he would worry about the most basic raw materials.

The major factories in Dabashan are not short of steel even in the most difficult times, because the ferry steel factory in Bashu will open up to supply them.

"In the old area, now you must strictly follow the process. You know, this set of technology is a combination of your original production technology and the machine tool production technology of the Soviet Union. Although it is not necessarily the best, it should be the most appropriate under the current situation. " After walking around the smelting workshop, Yun Fei 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 effect of natural aging in one year, do we need to carry out two artificial aging?" Yun Fei doesn't say that the technology is good. When it comes to the current technology, the remote mountain is fire.

Originally, the equipment for heat treatment was not enough, because the equipment they produced in the past was not artificially aged. At the beginning, they planned to produce machine tools three or even five years ago. In other words, the beds cast this year are generally placed neatly on the open space outside the workshop, 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, sun and its own gravity, followed by the deformation of the bed. At that time, as long as these deformed parts are processed, there will not be much stress left in the bed. After a short time of stress relief annealing before finishing, there will not be much residual stress in the machine tool.

In that way, the structure of the machine bed will become very stable.

Now, the production of machine tools by 91 heavy industry does not follow the rules that 9327 has been used for decades. Qu Yuanshan also knows that if these machine tool beds undergo natural aging for at least one year, Yunfei, the private boss, can't afford it at all.

In that way, it is estimated that the cloud will not be able to afford even if it has hundreds of millions of funds. According to the current wages of the whole 91 heavy industry, the whole factory, with more than 1000 people, has to pay millions of wages every year alone. In particular, the weight of these machine tool beds is in tonnage units. Take the current production capacity as an example. On average, 20 sets per day, 7000 or 7000 sets of equipment a year, which requires 20000 or 30000 tons of steel! That's tens of millions!

But anyway, there is no need to do a second aging treatment as if it was useless work when the equipment is not enough? The second artificial aging takes up a lot of low production capacity.

"In the old area, since we have produced, let alone the best, but at least we have to produce the highest level of machine tools we can achieve. On the surface, the second artificial aging is of little use, because at that time, the internal stress of the casting has not been much after the first aging. There are other stresses, but a small amount of stresses produced by processing engineering. " Yun Fei knows that Qu Yuanshan, the workshop director of the smelting workshop, understands this better than himself, but what he wants to say next needs this to pave the way.

"Although the lathe we produce is the most ordinary lathe, the precision is not high. But the old area, do you understand why so many domestic machine tool manufacturers are facing difficulties? Those large machinery factories are willing to buy the old machine tools of those bankrupt machinery factories, nor are they willing to buy the new equipment produced by those machine tool production factories? Do you know why? " When Yunfei saw Qu Yuanshan staring at him in confusion, he suddenly sold it.

Qu Yuanshan had heard a lot of nonsense from Yun Fei and was about to get impatient. What did Yun Fei say about stress? He, a college student who has worked all his life in smelting and heat treatment, can't he know? Later, when he heard Yun Fei talk about the difficulties facing the whole domestic machine tool industry, he listened patiently, but he didn't expect that the boy had sold in front of him.
