"The equipment we are going to enter next has high environmental requirements, and the environment of the second workshop is absolutely not suitable now!"

Hu Wenhai stood in the empty second workshop - this can be regarded as a miracle, Hu Hu did have some ability, and he really used the strength of the people in his hands to empty the entire second workshop in two days.

Although the second workshop was originally just a model workshop, the main thing was to make a sand mold wood mold, and the equipment was relatively simple and the volume was not large.

But the second workshop itself covers an area of nearly 900 square meters, at a glance is quite open, the so-called broken home is worth ten thousand, and decades have also accumulated a lot of heavy belongings.

The second workshop, which was once quite crowded, has now become empty, and even the electric hoist that was originally hanging on the roof beam of the workshop is now gone.

A group of people were standing in front of the gate at this time, looking at the second workshop that was about to usher in a new life.

"The conditions of our second workshop are not bad, how can this be changed, it was designed like this when the Soviets helped build it, and 80% of the workshops in the country are about the same!"

It was Hu Wenhai's rehired master who spoke, Wang Deyang, the original director of the second workshop.

He has been the workshop director of the second workshop for more than ten years, and no one can compare to him in the factory in terms of familiarity with the second workshop.

For the second workshop that has been emptied, he is a little regretful and a little looking forward to it.

It's a pity that the place where I used to work is no longer able to find those old friends.

What is looking forward to is the "mystery" that Hu Wenhai is about to introduce

production line.

In today's world, except for Hu Wenhai alone, no one knows what kind of products he has spent hundreds of millions of dollars on the equipment he has introduced in the United States.

With confidence in Hu Wenhai, Wang Deyang is looking forward to this batch of new equipment to make the second workshop more brilliant.

But Hu Wenhai was dissatisfied with the conditions of the second workshop, which made Wang Deyang a little difficult to accept.

The overall hardware conditions of the second workshop are absolutely good, the five-meter-high long-span workshop, the brick-concrete structure, a large number of steel beams and load-bearing reinforced concrete pillars are used, and it is not easy for the 501 factory to save this bit of belongings!

Hey, the little guy is the little guy, he doesn't know the truth of the new three years and the old three years, and the sewing and mending for another three years, and he wants to pursue new and fashionable things!

But Hu Wenhai is not like this, what did he do in BYD's Ningbo factory back then?

From the initial product qualification rate of only 40, to the later 95 grid rate, this road to improve product quality is promoted by Hu Wenhai step by step.

There are many advanced technological innovations and inventions, but there are also many not so advanced, even trivial details of chatting about improvements.

For example, the chip production line is well known to require a dust-free and clean workshop with extremely high conditions.

Personnel need to wear dustproof clothing, that is, use a rubber-plastic coverall, to cover the whole person.

However, the suit itself still needs to be exposed to the outside air, so it is inevitable that dust will remain on the surface.

In this way, before entering the production workshop, the staff wearing dust suits must first enter a dust removal cabin, which is a cabin where the dust on the dust clothing is blown away by the wind blowing from all directions.

The problem is that there will inevitably be wrinkles after the dust suit is put on, so that the wind in the dust chamber may not be able to completely blow the dust away from the dust suit.

For the sake of such a little bit of dust, Hu Wenhai led a research group of three doctoral students to squat in the dust removal cabin for a month, trying hundreds of postures -- and finally found a human posture that could blow the dust away from the dust suit to the greatest extent.

It's boring!

As a result, the project culminated in a paper demonstrating how plastic coveralls can be used to maximize the surface area under high air circulation conditions through changes in human posture.

Maybe it's really boring to study race outside, but for the high-clean workshop of chip production, such a study is finally reflected in the yield rate, which is an increase of 0.4 percentage points.

In fact, the so-called quality control is really such a trivial thing many times.

The 55 product rate increase in the Ningbo factory is supported by hundreds of such technologies.

Hu Wenhai is ready to make the project on the second workshop do not need such high perverted requirements, but in order to make the product quality meet the standards he requires, it is obvious that the conditions of the second workshop are far from enough.

"This kind of plant is only the technology of the Soviets in the fifties, and its environmental standards have long been outdated under the conditions required by modern production. ”

Hu Wenhai stepped on the cement floor, frowned, and said: "Director Wang, your cement floor is by no means suitable for modern fine production conditions, and it will produce a lot of dust in the friction of various moving objects! You can ask my grandfather, under the requirements of a trace of processing accuracy, if the key position of the equipment accumulates a little more cement dust, what will be the result." ”

Wang Deyang was stunned and was speechless.

This question doesn't need to be asked to Hu Shiwu, he can know the answer himself.

Whenever the superior issues a product production task, the first thing the operator should do is to maintain the machine.

Generally, it is routine maintenance, changing the engine oil, calibrating the machining accuracy, etc.

If the requirements of the product are very high, the maintenance of the equipment will be more perverted.

It is necessary to wipe every part of the equipment spotlessly with a clean cotton cloth dipped in oil, not only to correct the feed mechanism such as the tool, but also to recalibrate the transmission mechanism of the entire lathe...... It's not that the masters don't know the impact of the environment on the equipment, but they always tend to clean up when needed.

Is it just for a little dust to lay the floor on the ground?

Hu Wenhai is accustomed to seeing the production conditions of excellence in later generations, and does not feel that there may be any strangeness in controlling the quality problem at the source.

"There is also the exhaust ventilation of the second workshop, and the whole workshop is such a large space, and the ventilation depends on two doors and a few windows. As a result, there is poor air circulation, and hot air collects on the roof, enriching dust on various beams and roofs. Then in the production process, the enriched dust falls back to the ground, causing secondary pollution to the production environment, and these problems must also be solved!"

"The cement brick and earth walls are exposed, and the cracking is severe under dry and cold conditions in the northeast, which will also produce pollution to the production environment. The ground has not been waterproofed, and the groundwater is damp, resulting in high humidity in the workshop, which will cause chronic corrosion of the equipment, which will affect the product quality in the long run!"

...... The second workshop, which was already quite old, is now even more unbearable in Hu Wenhai's mouth.

Just walked and talked, so that he summed up more than 20 problems to be dealt with.

Do these questions exist?

Wang Deyang has to admit that there is indeed a zài!

Although there were problems in the past, it has been like this for decades, and it is not the same thing, which is to live in Bao for a long time and not smell it.

At least after such a trip, Wang Deyang was completely convinced by Hu Wenhai.

Regardless of other skills, people's eyes when they find problems are really vicious.

For the progress of human technology, the road to understanding problems and discovering problems is often the longest, and the time to solve problems is almost a moment in the long course of history.

It took hundreds of thousands of years for humans to look up at the stars, but it only took 2,000 years to get to the moon.

Therefore, asking questions and solving problems is equally important for evaluating a person's ability.

As for whether Hu Wenhai can only ask questions, Wang Deyang will not have to worry about it soon.

"This is the renovation map of the second workshop I designed, do you have any opinions?"

After Hu Wenhai finished picking out the thorns, he simply squatted down on the spot, spread out a stack of handwritten materials on the ground, and asked a group of masters to surround him, explaining the same: "This is a strip roof ventilator designed by me, which allows hot air to escape from the roof, and can be dustproof and waterproof. If it is manufactured with transparent plastic sheets, it can also solve the problem of lighting in the workshop. ”

"Oh, this thing is good!"

Wang Deyang Wenhai put out the hand-drawn design drawing, and he understood the key here at a glance or two, and immediately realized the benefits of this thing.

The roof ventilator is the standard configuration of the future steel structure workshop, and there is no technical content, but it is two vertical lighting panels hugging a horizontal lighting panel, which simply solves the problem of rain and dust.

But this thing is expensive in an idea, open a window on the roof, who would have thought of this?

However, of course, there is no similar design at this time, some factory workshops have ventilation buildings on the roof, but the structure is not so simple and convenient, and the dustproof and waterproof performance is not as good, and even the problem of air backflow on windy days will occur.

"It's just that if we need a clear plastic sheet, where are we going to get this thing?"

"This is easy to do, I know the director of Xiucheng Petroleum No. 6 Factory, I'll tell you this, he can always sell me two faces!"

"Oh?"

Hu Wenhai was also a little worried about the material problem, and the person who looked up suddenly became happy: "Okay, with Secretary Luo coming out, this is foolproof!"

Luo Likou has been the leader of the 501 factory for so many years, and the relationship between the industrial mouth of Xiucheng is very wild.

It's just a batch of lighting panels, and there is nothing difficult for him.

"And this, I have two ideas for ground handling. Normally it should be on the epoxy artesian floor, but this thing is not good, one alternative is to lay a wooden floor and then apply varnish, and the other is to simply apply tiles. Let's talk about which one you think is better and what you can do. ”

"If it's varnish on a wooden floor, the price is ......"

"Don't worry about the price!"

Hu Wenhai smiled and said confidently: "As long as the equipment can be started one day earlier, we can earn back any cost! Our task is to race against time to start the production line!"

"Oh, good fellow!"

Wang Deyang touched his head in surprise and said in surprise: "Then after doing it like this, the second workshop is not more comfortable than our workers' homes!"
