"There are no obvious defects, immediately arrange for transshipment, let the production task of the heavy parts processing workshop stop, and give priority to processing this!"

The mechanical properties of cast steel are higher than those of cast iron, but its casting performance is worse than that of cast iron, and the probability of defects such as porosity defects and inaccurate angle positioning in the casting process is several times higher than that of cast iron.

Otherwise, it is impossible to scrap more than 400 tons of parts directly because the defects are too large.

All kinds of measurements, inspections, and visual observations, and no defects were seen, which made everyone feel a lot more relaxed.

The surface roughness is far higher than the first two grades, the material formula of the molten steel has been changed, and the process has been changed, just this girder, to this step, has cost more than 2 million, not counting the scientific research cost of improving the process and researching the material formula, etc., if you count, it will be higher.

The state may also consider the cost problem to subsidize the scientific research funds of these units, rather than counting it into the 404 press, and finally let the 404 base give up because the cost is too high.

Hundreds of tons of parts, transferred from the foundry to the heavy machining shop, took more than a day.

There is no super-heavy crane that lifts hundreds of tons of parts, and there is no special transfer vehicle that can carry such a heavy and large part, the engineering and technical personnel of the large press team have adopted the most primitive method - rolling logs!

However, these rolling logs are not wood, but thick-walled hollow steel pipes with a large diameter.

It is used to push more than 400 tons of castings, not manpower, not manpower.

For this, the 404 Hongqi Machinery Factory specially modified two tanks, removing the armor and turret, pulling in front and top in the back, so that they could move this game slowly.

"Hey, if there are heavy-duty gantry cranes, there are heavy-duty transport vehicles, where do you need such trouble. Xie Kai sighed when he saw that such a primitive method was used to transport.

"We'll come later. Shen Hong told Xie Kai with certainty.

Now that thing is imported from abroad, the price is beyond the affordability of the big press team.

Xie Kai knew that there would definitely be in the future.

Zhenhua port equipment occupies most of the global market share, the crane used by the British to recruit the Queen Elizabeth aircraft carrier is imported from China, and when President President Ma of the United States gave a speech at the southern Miami port to promote the more extensive use of American-made, a gust of wind blew off the American flag on the gantry crane behind the president, revealing the two Chinese characters "Zhenhua" blocked by the American flag!

The chairman of Zhenhua Heavy Industries, who really wanted to give Aoheima a large amount of advertising money, didn't know the personal account of Aohei President Ma, so he had to give up in the end......

Thirty years later, the port equipment of most countries in the world comes from China!

It's a pity that now there isn't any, isn't?

No one can wait 30 years to start.

"If we have the funds, we can start working on all kinds of heavy equipment in this area now. In the future, we will definitely need a lot in our country. Shen Hong said, "These technologies require a large amount of funds and a large team to research. ”

Xie Kai and Zheng Yucheng did not answer.

Obviously, Comrade Minister wanted the 404 base to bear the cost of research on these heavy equipment.

Zheng Yucheng is not a fool, these large-scale equipment, the investment is large, and the recovery is slow.

The state is completely needed to invest, and the 404 funds can't withstand too much tossing at all.

"Minister Shen, our stall is already very big now. If it weren't for the big press to develop the development of many of our projects, we would not have tightened our belts and spent 200 million yuan to engage in this project. Zheng Yucheng hurriedly began to cry poor.

For him, he doesn't care what major national equipment is not major equipment, what he cares about is the development of weapons and equipment!

As he said, if it weren't for the importance of the big press, the 404 would not have been invested at all, and the funding needs were too huge.

Even if it weren't for Shen Hong, the incomparably powerful minister of industry, personally presiding over it, it would have been difficult for 404 to mobilize the strength of the national heavy industry system to carry out this project.

"Don't cry poor, it's useless to cry poor. I'm just feeling emotional. Shen Hong glared at Zheng Yucheng. "The development of the industrial field is complementary to each other, and if there is a gap in any one, it will be difficult for the whole system to develop. ”

"Indeed. There are some things that can only be waited. Xie Kai also spoke.

"In those days, I came into contact with Soviet engineers who came to China to provide technical assistance, and some wanted to develop only industries that could produce quick results. But they don't know that the construction of the industrial system is like the internal strength in our martial arts. In the beginning, it didn't work out much, and it took a lot of money and time. Once you have a good foundation and learn any martial arts, you will ...... very quickly."

"Old Shen, have you watched "That Rabbit"?" Xie Kai asked for no reason when he heard this.

He had always suspected that Shen Hong, the big man, was a member of the Reborn Crossing Army.

His whole life is really as open as Xie Kai.

He presided over the nine complete sets of industrial equipment that have supported the country's industrial development for decades.

"What rabbit, this rabbit?" Shen Hong looked confused.

Zheng Yucheng and others were even more confused.

What is this thing coming out of this kid's mouth?

Xie Kai couldn't wait to give himself a slap.

"I heard someone tell me a story before, that is, about a little rabbit learning martial arts......" Xie Kai consciously lost his words and hurriedly changed the topic, "The industrial system is indeed like this. It is because our system has not been developed that the state has launched so many key military equipment projects...... If we had a better foundation, it would be easier for us to do anything, wouldn't it?"

The importance of the industrial system becomes more and more important the further you go.

After the collapse of the Soviet Union, Mao Xiong couldn't even manufacture the conventional engine of the destroyer in the end, and had to import it from China; Europe listened to the fool of the United States and engaged in global trade, and in the end, it found that all the people who made money were taken away by the Americans, and the British had to build an aircraft carrier for countless years, and then, they did not have carrier-based aircraft, so they could only purchase them from the United States at a high price; the Germans came up with the Leopard-2 tank, which was obviously better than the American M1, and in the end the Americans still equipped their own domestic tanks......

Even, when it came to the Sino-US trade war, the Americans found that even their president who shouted that they wanted to use American-made presidents, all kinds of things during the election were from China, and even the American flag was made in China!

"Just you kid understand!" Zheng Yucheng was afraid that Xie Kai would promise indiscriminately at that time, so he hurriedly reminded Xie Kai.

"You two don't act here, even if I really want you to do this heavy equipment, I won't let you do it. A system has to be worked hard by the whole country to make progress together. The weight of heavy industry is beyond the reach of a single unit!" Shen Hong sighed.

In his eyes, there is a lot of loneliness.

"But the big press is a new stage for us, with this thing, we can make a lot of heavy equipment in the future, we can make it ourselves. Especially in the field of extra-large and major equipment. Shen Hong said.

Without waiting for processing, Shen Hong left the double layer.

He has a lot to do.

"Clamping is also a troublesome thing, hundreds of tons of large parts, every process, and even every aspect of processing, is a huge challenge for us. Chu Guorong looked at the casting on the huge gantry planer, in order to find out the first surface level of processing, it took three whole days, helpless.

Thanks to the gantry planer, the beam can be moved by the guide rails below without moving the parts, otherwise the guide rails of the machine will be crushed.

After the whole part is aligned, it doesn't even need to be pressed, and the gravity of more than 400 tons of its own and the cutting force generated during processing cannot shake the parts at all.

Driven by the beam, the planer knife scooped out pieces of silvery-white iron filings the size of a fingernail and flew straight to the side.

For parts more than ten meters long, the planer knife can't go back and forth three or five times, so you have to stop, replace the planer knife, and then continue......

Xie Kai has long known that the larger the part, the more difficult it is to process, and it can be months or even years at every turn.

But I didn't expect that when I saw it with my own eyes, I would think that the processing speed was so slow.

He saw with his own eyes that in the morning, he couldn't cut a few knives, and then time ran out......

"Let's go, we can't change anything while we wait here. According to technical analysis, the probability of the casting being qualified reaches 82%. Zheng Yucheng said to Xie Kai.

It took more than ten days here.

Before you know it, it's already August.

After Xie Kai got better, Sun Juan and Mo Qi stopped going to see the panda, and found that Xie Kai had been fattened and began to grow sideways, and the two girls decisively asked Zheng Yucheng to arrange for them to go to the Daliangshan area to inspect the situation of out-of-school children.

Xie Kai couldn't wait for them to leave, so he directly asked Zheng Yucheng to agree, and he was happy.

Just on the farmer's planer, one noodle was processed for several days.

After processing a surface, the double man used the liquid penetration method to detect surface defects, and the huge surface was much better than the original estimate before production.

Zheng Yucheng felt that he couldn't accompany Xie Kai to spend any more time here.

"Have those people been discharged from the hospital?" Xie Kai asked Zheng Yucheng.

"Wang Feng's family is reluctant to go with us. Zheng Yucheng knew what Xie Kai was asking.

"She won't think about her own children?" Xie Kai asked with a frown, "Let's go, I'll talk to her." ”

"Her name is Ji Yujuan, and she didn't have a good composition in her family, so she just graduated from junior high school......" While walking, Zheng Yucheng introduced the situation of Wang Feng's family. "You know, there were a lot of people whose futures were changed in those decade. The two of them are childhood sweethearts, otherwise it is impossible for them to become husband and wife......"

Xie Kai naturally knew.

At that time, people with poor family composition, whether it was work or marriage, were seriously affected.

If it weren't for the bad family composition, the old lady wouldn't have been able to marry her father, right?

Zheng Yucheng obviously knew where Ji Yujuan's house was, so he didn't look for someone from Erzhong to lead the way, and he didn't even inquire along the way, and went directly to Ji Yujuan's house.

As a technician in the factory, even if Wang Fenggen is young, for some reason, the house did not fall on his head.

If nothing happens, just by virtue of the successful casting of the main beam of the large press, his family will be able to share the house.

This is a bungalow built during the construction of the factory, the streets are paved with bricks, and the original color has long been discerned, and the outer walls of the surrounding houses are mottled.

"Leader Zheng, I didn't say it, our unit has solved my husband's matter, and our life is guaranteed......," Ji Yujuan still had a haggard face, wearing a patched men's gray shirt and a black veil on her arm.

Three children were missing.

Ji Yujuan said to Zheng Yucheng and Xie Kai, who entered the door, "Thank you very much for your concern, my husband sacrificed for the country, I can't take the state's pension, accept the establishment of the unit, and then accept your benefits......"

This woman's education level is not high, but her consciousness is so high that Xie Kai is extremely ashamed.

Zheng Yucheng looked at Xie Kai with a strange expression, obviously to let Xie Kai see the consciousness of others.

"Eldest sister, listen to what I say first, if you still think like that, we won't force anything. The reason why we came to you is not because Comrade Wang Feng sacrificed sympathy and pity ......" Xie Kai organized the language.

Ji Yujuan is a very strong woman.

Obviously, one person can't support three and a half children, even if the factory arranges a regular job for her, the salary is far from enough to feed the three children.

Half-sized, eat poor old man.

Originally, when Wang Feng was still there, the life of the family was not very good.

"Comrade Wang Feng is giving his life for the big press project, and he is an example and model that every national defense science and technology worker needs to learn. If you are given a bereavement that goes beyond the prescribed provisions, it will be disrespectful to Comrade Wang Feng's sacrifice, or even an ......insult," Xie Kai said solemnly.

Zheng Yucheng looked weird.

When did this kid start saying these official clichés?

Ji Yujuan listened to Xie Kai's words and was very disgusted, but she didn't say anything.

"Eldest sister, the reason why we propose and want you to go to our side is, on the one hand, because we need people like you. On the other hand, it can give Comrade Wang Feng's descendants a better future. Xie Kai finally got to the point.

Talking about official words and clichés, he can't even say it himself.

"Here, too, they will have a great future. The leader of the unit said that when the child is older, if he can't be admitted to college, he can take over. Ji Yujuan said with a straight face.

Xie Kai didn't care about Ji Yujuan's attitude, and grinned, "As a worker, can you make a contribution to the country compared to becoming a technician or even an engineer?"

Ji Yujuan looked at Xie Kai and stopped talking.

She didn't understand what Xie Kai meant.

"With us, all the children start their studies from a young age, go all the way to university, and then go back to our base to take over their parents' classes...... You should have heard of what Comrade Wang Feng's parents do, so is it really good to let your children become ordinary workers?" Xie Kai continued.

Obviously, Ji Yujuan was a little relieved, "You can guarantee to let your child go to college?"

"It's not guaranteed. Xie Kai shook his head, "However, as long as they work hard, even if they are not admitted to the ideal university, the teachers of the admissions office of our unit's children's school will call the school next to the school to help make up the ......."
