"Old district, how many 40-bed beds have been produced?" Yun Fei found Ou Yuanshan, who was not staying in the office, but staying in the workshop site, and asked him.

"During this time, the furnace did not stop heating 24 hours a day, and it was only the bed of more than 400 lathes, and if we want to reach the scale of the minimum production of 50 units a day, our production capacity cannot be reached in a short period of time. Besides, produce so much? Can it be sold? Ou Yuanshan really didn't understand where this young boss got so much confidence.

It's been almost half a month, and Yun Fei has been urging the mass production of the beds of these machine tools. Although the follow-up processing has also begun to be produced one after another, the 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, that is half a year later, now we don't consider this problem, within half a year, for those newly recruited molding sand workers, you have to train it quickly." Yun Fei didn't explain to Ou Yuanshan why he would have a large backlog of blanks in the factory at the beginning.

It takes at least a month for a lathe to be assembled from the time the iron ingot is put into the smelting furnace to the final assembly. If there is no second-hand aging equipment that Kamat bought from Japan, which can carry out the artificial aging of normalizing and tempering these two or three meters long beds, even if it is a year, the first lathe of Jiuyi Heavy Industry will not be able to go to the market.

The original 9327 factory left not a lot of machine tool beds, a total of only more than 600 units, the most after the loser factory director as scrap iron sold a lot, after Yun Fei took over, a statistic, there are only more than 200 units left.

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

The machine bed, rusted on the outside, is now in the semi-finishing workshop built with the equipment of the finishing workshop of the 9327 factory and some equipment shipped back from the Soviet Union. Waiting in line for the portal milling machines, which were far larger than them, several times or even ten times larger, to mill off the thick layer of rust on their surface.

"By the way, Xiaoyun, our aging processing furnace is not enough, a furnace can only process the bed of two lathes at a time, that is, the largest one, can only process six at a time, we only have four sets of furnaces for heat treatment, and now we are dealing with the aging processing time is long, do you think you can add some?" Ou Yuanshan seems to understand everything about Yun Fei, the boss, on the surface. But in fact, the young man who didn't understand anything could only sigh helplessly in his heart.

If Zhaoyun does not do this, even if a lathe is produced, one can be sold, and 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 filled with the bed castings produced.

Now there are more than 400 sets of equipment, which have taken up half of the area.

"That's a problem, but let's not get busy with this equipment just yet. Let's just take the equipment in the factory. "For those stoves that can be found in this era that can be used for heat treatment and aging treatment, they are about to become obsolete. Yun Fei really didn't want to add too much.

Although these annealing furnaces, normalizing furnaces, tempering furnaces are not expensive in this era, because of these furnaces. Basically, it's all the same, the only difference is the heating temperature. A large set is only two or three hundred thousand, but the efficiency of those devices is really too low. The cost of production is too high.

The 9327 used to use its own equipment can basically be manufactured by itself, but the cost is higher than buying two outside. Especially since many of the old mechanics have retired, and now these workers. I haven't produced these furnaces by myself for many years, so at the beginning, Yuan Shan just became the director of the workshop, and when he heard that Yun Fei planned to reach a daily production capacity of 50 units within a year, he proposed to manufacture some furnace bodies, but Yun Fei denied it.

At that time, Yun Fei said that we are no longer the kind of production that we used to produce regardless of cost, and Jiuyi Heavy Industry can't make all the money by itself.

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

For the foundry workshop, Yun Fei only knows the hot air cupola.

There is a vent inside and outside the furnace, and a blower is used to ventilate the inside of the furnace directly, so that the high temperature zone in the whole furnace is extended, and the temperature in the whole furnace is heated faster.

At that time, when these equipment were being renovated, he also proposed his own 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 Feizhi said that in this era, there was the production and sales of this kind of equipment in China, but the price was far more than these ordinary smelting furnaces. The current Jiuyi Heavy Industry does not have any income of any money, and the funds are already tight, and the money earned from the talent trade with Kamat has been replaced by him for those low-cost equipment in the Soviet Union.

Otherwise, with the kind of heavy equipment of the original 9327 factory, there are not many heavy equipment, and even many things are produced by hand, and even ten machine tools a day cannot be produced.

The largest melting 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 a ton, and a furnace of molten iron is enough for the number of six lathe beds. The smelting furnace is the main production force of the whole workshop, and the molten iron melted by other small smelting furnaces is used to pour some small castings such as the foot of the lathe and the headstock box.

Every day, dozens of tons of iron ingots are turned into molten iron, which is then poured into molds made of molding sand and turned into various parts on lathes.

The current price of steel is not cheaper than that of future generations, and even money may not be able to buy it. If it weren't for Yun Fei's factory, which was the original 9327 factory of the Ninth Academy, even he would have to worry about the most basic raw materials.

The use of steel in the major factories in the entire Daba Mountain is not lacking even in the most difficult times, because the Dukou Iron and Steel Factory, which is also in the land of Bashu, will be open to supply them.

"Old district, now you are producing, you must strictly follow the process. You must know that this set of processes is a combination of your original production process and the Soviet Union's machine tool production process. Although it may not be the best, it seems that it should be the most suitable in the current situation. After Yun Fei walked around the smelting workshop, he prepared to go to the machining workshop.

"Xiaoyun, I said, since more than ten or twenty hours of artificial aging can exceed the effect of natural aging for one year, can we use two artificial aging?" Yun Fei doesn't say that the process is okay, when it comes to the current process, the mountains are fire.

Originally, the equipment for heat treatment was not enough, because the equipment they produced in the past was not artificially aged. When they first produced machine tools, the plans were issued three years ago or even five years ago. That is to say, the bed cast this year will generally be placed neatly in the open space outside the workshop, let the wind and rain shine, 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 away, the stress that remains inside the bed, the rest is not very much, and after a short time of stress relief annealing before finishing, the residual stress inside the machine tool will not be much.

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

Now Jiuyi Heavy Industry produces machine tools, not in accordance with the original 9327 used for decades to go the rules. Ou Yuanshan also knew that if these machine tool beds were allowed to go through the natural aging of at least one year, Yun Fei, a private boss, could not afford it at all.

In that case, it is estimated that Yun Fei will not be able to afford even if he has hundreds of millions of funds. According to the current salary of the entire Jiuyi Heavy Industry, the entire factory, more than 1,000 people, has to pay millions of dollars every year. In particular, the weight of these machine tool beds is in tonnage, take the current production volume as an example, an average of 20 units per day, a year to 78,000 pieces of equipment, which is 20,000 tons of steel! That's going to be tens of millions!

But in any case, there is no need to do a second aging treatment as if it is useless when the equipment is not enough, right? The second artificial aging time limit has taken up a lot of the already low production capacity.

"Old district, since we have produced, not to mention 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 not of much use, because at that time the internal stress of the casting has not been much after the first aging. There are also stresses, but some small amounts of stress generated by the processing process. Yun Fei Zhilu said, for this, the workshop director of the smelting workshop in Ou Yuanshan understands better than himself, but what he is going to say next needs this to pave the way.

"Although the lathes we produce are just the most ordinary lathes, the degree of precision is not high. But the old area, do you understand, why are so many domestic machine tool manufacturers facing difficulties? Are those large machine factories willing to buy the old machine tools of those bankrupt machine factories, rather than buy the new equipment produced by those machine tool production plants? Do you know what this is for? Yun Fei saw Ou Yuanshan staring at him with a confused expression, and suddenly sold out.

Ou Yuanshan originally 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 worked in smelting and heat treatment all his life, can he still be unclear? Later, when he heard Yun Fei talk about the predicament that the entire domestic machine tool industry is now facing, he listened patiently, but he didn't expect that this kid would actually sell Guan Zi in front of him.
