Liu Xuanliang's life soon returned to calm, except for promoting the development of solid rockets step by step, occasionally going to the propellant production plant in Yumen, and the rest of the time, he would go to Bai Yu's liquid rocket engine project team several times a day.

However, just a week after the leisurely days, Liu Xuanliang's solid rocket engine project team received a new project: based on the NK-33 engine, the corresponding high-altitude rarefied air environment and vacuum environment engine were developed.

After receiving the project, the people of the 201 Solid Rocket Engine Institute were boiling: the development of high-altitude environment and vacuum environment engines means that "putting satellites" will be a matter of several years.

While others were cheering enthusiastically, Liu Xuanliang stared at the interface parameters of the control mechanism in the two project task books, and fell into deep thought: it was not that the requirements were too slow, but that the margin of the parameter range given by the interface was very large, and it was very likely that his old man had made a move......

Due to the rocket's own fuel and oxidizer, the new engine at high altitude and in a vacuum had a similar frame to the NK-33, except that the shape of the nozzle, the flow of the circulating cooling pump, and the fuel pump changed due to changes in thrust requirements.

Since the solid rocket is also a multi-stage arrangement, the liquid fuel used in the high-altitude and vacuum environment is launched, which has great reference significance for the solid rocket engine used in the same environment......

Although it was established later than 202, the 201 Institute where Liu Xuanliang is located not only undertook the development of solid rocket launches, but also the development of multi-type missile engines and rocket shells; Thus, the staffing of 201, much larger than the 202, which was responsible only for liquid-fuel engines.

However, after Liu Xuanliang became the "son-in-law of 202", the voices of Bai Yu's subordinates complaining about the compilation and numbering of 201 gradually disappeared......

After giving Liu Xuanliang a letter of responsibility for the new project, Liu Xuanying rushed back to the headquarters of the steel plant: there were still some things she needed to deal with.

In the factory area of Jiuquan Iron and Steel Plant, Liu Peng, Minister of Military Industry of the General Headquarters, looked enviously at the blast furnaces in the factory area, as well as the various workshops lined up one after another. The receptionist of Jiugang, who followed Liu Peng, patiently introduced the scale and purpose of various workshops to Liu Peng.

Ma Xuanzhong, who accompanied the visit, remembered the situation five or six years ago, when he first started to expand, when he first started to expand: there were not enough people, and his father went into battle shirtless at night, finished talking about metallurgy, and then talked about machining technology; The apprentices who have just entered the factory and the master who have been recruited from the factory have been recruited, and when they are off duty, they study in addition to sleeping......

Later, the old man transferred a large number of professional personnel and equipment from abroad, and gradually expanded the scale of the steel plant to the current extent.

"The front blast furnace was the hero of our Jiuquan Iron and Steel Plant when it started, but later, the production capacity could not keep up with the requirements, so it was mothballed."

Liu Peng looked at the tightly covered blast furnace in front of him, and was a little speechless: "With such a large furnace, the production capacity is not enough?" ”

Ma Xuanzhong took a step forward, looked at the long-lost "old comrade", and sighed: "The ore from Qilian Mountain was originally used, because the enrichment process of ore powder has not been up to par, and it needs to be refined many times, so the production capacity has not been able to go up. ”

"Oh!"

Liu Peng nodded: "Then us?" ”

Ma Xuanzhong smiled: "We will provide Yanzhou with enough high-grade mineral powder, and from now on, our master can teach it hand-in-hand, and after the church, we will dismantle the furnace." As for the details......"

Ma Xuanzhong looked at Liu Xuanying, who was rushing here: "You can talk to the person in charge of our factory." ”

……

After settling the interns in Yanzhou, the pony who was in charge of hospitality by Jiuquan Iron and Steel immediately rushed to Liu Xuanying's office.

"Boss ......"

Liu Xuanying glared at Xiaoma: "If you call the director in the factory, you have to act like a bandit." ”

"Alright, Director." The pony is a little helpless, there is a strange boss, and it is a little difficult to be a subordinate.

"What's the matter?"

Xiao Ma replied as if he was invited: "The old horse head who is responsible for leading the internship quietly told me that there are many good seedlings in the internship team. ”

"Listen!"

"I said, aren't we ......?"

Liu Xuanying glared at Xiaoma: "If you can turn your father into a Buddhist, I will find a way to keep a few people." ”

The pony sighed wryly, "Forget it then!" ”

"It's good to know, it's not easy for the Chinese Communist Party to gather so many people, if I open my mouth, I will definitely be able to leave a few, but ......" Liu Xuanying frowned, "If you really have the ability to stand out, let Lao Ma inform me first." ”

"Okay!"

"Also," Liu Xuanying stopped the pony who was walking out the door, "Tell the people next year and the comrades of the Chinese Communist Party, during the internship, the people from the intelligence department have been staring at it, so that they don't think too much." ”

When he heard that there was someone from the intelligence department, Pony's eyes lit up and he nodded happily: "Okay! So I went? ”

The next day, the "old qualification" of the steel plant, Lao Ma Tou, met with the interns of the Communist Party of China with a temporary internship guide. Then with a group of "interns" began to dismantle the outsourcing of the blast furnace......

After dismantling the outsourcing, the furnace was cleaned again; After the blast furnace was cleaned, the open-hearth was cleaned again......

At the end of the day, the arrogant interns complained bitterly.

The instructor in charge of leading the team found Liu Peng.

Liu Peng didn't speak, just went through the internship notes and looked through them carefully......

After reading it, Liu Peng's face darkened: "Lao Wu, you are also an old comrade, you have also worked in Hanyang Iron Works before, and people have also told you that work is not useless, but you ...... Hey, let's lead the team according to Hanyang's set......"

Lao Wu was stunned for a moment, staring at Liu Peng with a blank face.

Liu Peng sighed and explained: "If Jiuquan is still like a bear in Hanyang, why did the central government send you to Jiuquan?" It's better to go to North Sudan! ”

Lao Wu couldn't believe it, his eyes widened.

"Where do you think those high-quality steel ingots from our arsenal came from?" Liu Peng glanced at Lao Wu, "The steel industry here in Jiuquan was built by themselves little by little. The problems that need to be paid attention to in the smelting process of iron and steel plants, they know better than us, learn more and ask more questions. In the future, when we make our own steel, we will have to rely on ourselves when we encounter problems. ”

Lao Wu nodded......

In the theory class on the second day, Lao Matou found that the apprentice from Yanzhou had many rules, and nodded with satisfaction.

In the Jiuquan Iron and Steel Plant, there is a slogan everywhere, and the details determine success or failure. This is not an empty phrase, but an experience gained only after suffering losses and teaching tuition.

For blast furnaces, tens of grams of dust remaining in the furnace may eventually lead to excessive impurities in the ingots; If the furnace is not cleaned during smelting, the ingots will not appear in the textbook......
