The Rise of Heavy Industry 1980

After dinner, Wang Chaoyang was about to drive Zhang Miaomiao home, Chen Xianglong left on his own very interestingly, and did not forget to say goodbye to Zhang Miaomiao politely before leaving, "goodbye, sister-in-law."

On the way to Zhang Miaomiao's house, the girl kept her little face tight.

"Chen Xianglong is your friend, why is he so out of tune!"

"We grew up together, and we are very good people." "

Tell him, don't call me again...... Don't call me that anymore!

" "It's just a salutation, so why bother. Wang Chaoyang was indifferent.

......

Santana stopped at the door of Zhang Miaomiao's house, Wang Chaoyang sent her home, and Zhang Lianjun enthusiastically pulled her into the house to drink a cup of tea, and then Wang Chaoyang left.

Early the next morning, Wang Chaoyang came to pick up Zhang Miaomiao on time. After sitting in the co-pilot, Zhang Miaomiao found that Santana was not driving in the direction of Changhai Agricultural Machinery, so he asked: "Aren't you going to work?"

Wang Chaoyang said: "I said it yesterday, and today I will explain to you the method of manually eliminating internal stress."

Zhang Miaomiao suddenly came to the spirit: "Where are we going?"

Wang Chaoyang said: "Go back to the Red Star Factory."

On the way back to the Red Star Factory, Zhang Miaomiao was full of doubts, she didn't know what the elimination of internal stress had to do with the Red Star Factory. As far as she knew, the Red Star Factory had even used very few castings before.

Wang Song seemed to have known that Wang Chaoyang would come back today, and waited at the gate of the factory early, Santana had just stopped, and the old factory director came to the car door and said: "The third child, you are back, the equipment has already been prepared, come and take a look!" Wang Chaoyang nodded and followed the old factory director to the

workshop.

Zhang Miaomiao had the heart to ask, but the father and son walked very fast, and she didn't have a chance to ask, so she had to follow behind.

Zhang Miaomiao is very familiar with the interior of the Red Star Factory, but when she walked to the inside of the warehouse this time, she found that a compartment had been built in the corner at some point, made of red bricks and cement, and it seemed that it had not been for a long time.

In the cubicle, there was a set of equipment, and Zhang Miaomiao was even more surprised after seeing it. The equipment was very strange, and at the bottom was a two-meter-square steel plate, on which were placed three machines that looked like blowers, and the outlets of the three "blowers" were angled together, and on the outside of the "blowers" was set up an iron trough with a lot of white fine sand.

"Chaoyang, I started to prepare on the day you went to the city, see what it looks like, can you use it?" Wang Song said.

"Well, Daddy is amazing, even better than I thought. Then give it a try now!" Wang Chaoyang said.

"Okay, you and Xiao Zhang get out of the way, I'll do it.

Wang Song picked up an iron plate from his waist, put it in the middle of the "blower", pressed it with an anvil like a scale, and pressed the power switch on the side.

The three "blowers" of the "buzz ......

" were running at the same time, and the white fine sand in the sand trough was sucked in by the "blowers", and then shot out at high speed, and then hit the surface of the iron plate, making a "crackling" sound.

For a while, there was a roar of noise in the compartment, and sand and gravel were flying, if Wang Chaoyang hadn't pulled Zhang Miaomiao aside, the two of them would have suffered.

The more Zhang Miaomiao looked at it, the more strange it became, and she didn't know what she was doing at all.

"Buzz...... Crackling and popping ......

" lasted for more than ten minutes, and the old factory director finally turned off the power, the three "blowers" stopped working, and the compartment was quiet.

"Look, the effect is similar to what you described!" Wang Song picked up the iron plate that had been "baptized" by sand and said to Wang Chaoyang, the current old factory director was full of ashes, but he still grinned his teeth.

"Hmm. Very good. Wang Chaoyang wiped off the sand and dust on the surface of the iron plate, looked at it carefully, and nodded with satisfaction.

Zhang Miaomiao was also observing the iron plate, and found that there were many dense pits on the surface of the originally flat iron plate at this time.

From the beginning to the present, Zhang Miaomiao has become more and more confused, and finally couldn't help asking: "Factory director, Wang Chaoyang, what are you doing?"

"Oh Xiao Zhang, you don't know yet, let me tell you first!"

The old factory director who was in a good mood said excitedly: "Before you went to Changhai Agricultural Machinery, Chaoyang told me to prepare such a single room in the factory." Three blowers plus an iron trough, the blower and the iron trough are easy to prepare, but the difficulty is on these white sands, in order to find the white sand I ran several quarries!"

"What is the purpose?" Zhang Miaomiao still did not understand.

"The purpose is to deal with steel plates in this way!" Chaoyang also said a word...... Oh, look at my head, I can't remember......" Wang Song scratched his scalp and said.

"Internal stress?" Zhang Miaomiao blurted out.

"Yes, yes, yes, yes, it is internal stress, Chaoyang said that this equipment is related to internal stress...... But I don't know why. Wang Song said loudly.

Zhang Miaomiao looked at this set of equipment again, and "internal stress" was something she had just suddenly thought, but in fact, she still didn't know what this set of patchwork equipment had to do with internal stress.

At this time, Wang Chaoyang explained: "Dad, Miao Miao, let me explain." There is internal stress in the casting, and I won't say much about the reasons, but what I want to talk about now is the method of eliminating internal stress. This set of equipment, through the high-power blower with fine sand to hit the steel surface, the resulting impact force causes the internal structure of the steel to vibrate, this dense high-frequency vibration can eliminate the internal stress of the steel in a short time.

Wang Song was confused, but he kept nodding.

Zhang Miaomiao instantly understood and said: "Using this high-frequency impact method, the internal stress of the casting can be quickly eliminated and the production efficiency can be improved...... This is a wonderful idea!"

Wang Chaoyang smiled and said: "If this method is used on the chassis of the CC20-3, it should be very effective."

Zhang Miaomiao's mood instantly rose: "Then let's go back and tell Director Hu and let him arrange someone to do it as soon as possible?"

Wang Chaoyang smiled faintly. Wang Song also bared his teeth and laughed.

Zhang Miaomiao couldn't help but feel strange when she saw the strange smiles of the father and son.

At this time, the old factory director explained: "Xiao Zhang, you girl is straight-minded, what is the benefit of telling the method now, what is the benefit of our factory?"

......" Zhang Miaomiao was stunned, she didn't think about it.

"This set of equipment and this way of processing was thought up by Chaoyang, it is the secret of our factory, of course, we must take the opportunity to get the order for the gearbox chassis!" Wang Song said with a smile.

"......" Zhang Miaomiao continued to be speechless, and said in her heart that you two are really father and son!

Of course, to be honest, Zhang Miaomiao is also very happy in her heart, she is also from the Red Star Factory, and the Red Star Factory has the opportunity to expand its benefits, which is also what she hopes to see.

At present, the Red Star Factory already has orders for shafts and gears, and if it can win the case order, the turnover can at least triple again. Because as the largest part of the CC20-3 gearbox, the price of the chassis is also the most expensive, close to 100.

However, before that, the Red Star Factory had to overcome another problem, that is, the supply of castings.

There are not many factories that have the ability to produce castings, and the Red Star Factory does not have this ability at present, which means that if the Red Star Factory wants to win the chassis order, it must solve the supply problem!

"Dad, have you made an appointment with the people of Black Mountain Metal?" Wang Chaoyang asked at this time.

"Of course, I made an appointment, and I heard that there was 'fat meat', and Liao Zhiyong promised to come to talk in person. Wang Song smiled and said, "I think the time should be almost up." "
