"Suspension checks?"

Listening to Tong Wenlie's words, Lu Jiadong was a little stunned, even if Tong Wenlie sent a telegram in violation of regulations, at most it was a notice of criticism, and it was good to do a written inspection, but now, Tong Wenlie was suspended for inspection, which was obviously a way to deal with the crime plus one degree, which made Lu Jiadong unable to figure out why Tong Wenlie, an old expert who only understands technology, was sentenced so heavily by Liu Wenzheng........

Tong Wenlie naturally saw what Lu Jiadong was thinking, and couldn't help but smile miserably, with the yellowish table lamp in the study, he looked even older and gloomy:

"Sending a telegram is naturally not a crime, but the bad is my mouth, and I shouldn't tell so many truths........."

After all, this is related to the future development of the Northeast Heavy Industry Group, and no one dares to slack off, so soon the relevant investigation team was established, and the reason for the failure was also found out at the first time, because the missile body was not manufactured properly, resulting in the missile body in high-speed movement, it could not withstand the huge resistance and pressure of the air, resulting in the cracking of the missile body, which eventually led to a fire and explosion........

Originally, it was not a bad thing to find out the cause, and it was necessary to solve the problem by prescribing the right medicine, but I didn't expect that the research and development team of the new air defense missile system and the No. 1 Aerospace Factory, which was responsible for the production of the missile body, had prescribed two completely different prescriptions:

The new air defense missile system development team with Tong Wenlie as the core summed up the previous failure experience, and finally locked the problem on the casting process, you must know that the air defense missile body is a large piece, the internal structure is complex, and it is difficult to completely process it by general machining, and the previous failure is the best example, because of this, Tong Wenlie's plan is to use the most traditional sand casting to complete the casting of the air defense missile.

However, once his plan was proposed, it was opposed by Liao Yongchen, the new director of the first aerospace factory, who believed that the traditional sand casting was too simple, out of touch with the times, and the use of pure manual, long production cycle, slow completion efficiency, not suitable for the current industrial production at all, was eliminated by the times is inevitable;

The reason why there is a problem with the body of the air defense missile is that the missile development team adheres to tradition and is rigid in thinking, resulting in the serious aging of the machinery and equipment of the production line............

Originally, it was normal to have two different solutions to solve a problem, and it was natural to make a judgment after the actual operation test, but I didn't expect that Liu Wenzheng, who was actually presiding over the work, did not inspect and investigate at all, so he decided to use Liao Yongchen's equipment introduction plan.

Tong Wenlie is a person who strives for perfection in technology, and he is a person who does not rub sand, and he has done more than half a month of experiments in the foundry for this reason, and has mastered first-hand information and data, so when Liu Wenzheng found him and asked him to agree to introduce relevant equipment, Tong Wenlie refused bluntly,

Even if Liu Wenzheng was forced in person, Tong Wenlie still refused to sign the relevant documents with his stubborn character, thinking that with him, the chief designer, it would be impossible for Liu Wenzheng and Liao Yongchen's equipment introduction plan to be completed, and when Lu Jiadong came back, he would naturally be able to make a fair judgment, but he didn't expect Liu Wenzheng to directly engage in such a hand, and completely move Tong Wenlie's stinky and hard stone away by the fault of illegal reporting...........

"Although I know that these two people are also for the development of the group, and I am not opposed to the introduction of equipment to foreign countries, it also depends on the actual situation, knowing that machining cannot complete the complex manufacture of the missile body, so why use precious foreign exchange to buy some useless things? What is the difference between such an unrealistic approach and the 'release of satellites' in those years...........

The more Tong Wenlie spoke, the more angry he became, and in the urgency, he slapped the armrest of the chair with his hand "Bang~~Bang~~", and Lu Jiadong suddenly realized after listening to the cause and effect, no wonder Liu Wenzheng saw that he was a little unnatural, presumably he also felt that it was a bit too much to suspend Tong Wenlie for inspection like this,

I'm afraid that he, the helmsman, will settle accounts after coming back, anyway, Tong Wenlie was invited back by him Lu Jiadong's "three visits to the thatched house", and attacking Tong Wenlie is attacking him Lu Jiadong from another aspect, if you really think about it, even if it is Liu Wenzheng's party ~~committee~~book~~ Ji, he may not be able to withstand his thunderous anger, so he only thinks about solving the matter completely, so that he can give an explanation to himself, but he didn't expect to receive the telegram and rush back early, which made Liu Wenzheng's plan a little chaotic..........

Thinking of this, Lu Jiadong nodded slightly, but he didn't speak, looking at Lu Jiadong, who still looked as usual after listening to the cause and effect, Tong Wenlie was a little puzzled, for fear that Lu Jiadong would also agree with Liao Yongchen's plan because of his great success, and couldn't help but say anxiously:

"Mr. Lu, you can't get carried away because of these surface projects, imported things are good, but it also depends on whether it is with us, if the water and soil are not adapted, it is no different from scrap copper and rotten iron, not to mention that the internal structure of the missile body is complex, the overall molding requirements are high, and it is difficult to complete simple machining, although the traditional process is relatively backward, but sometimes they are the only way to solve the problem.........."

Tong Wenlie's words were earnest, and even a little pleading, there was no way Liao Yongchen's plan, the temptation was too great, updating equipment, solving problems, overall transformation, upgrading and improving, any one of them was extremely tall, and any leader could not help but be tempted when he heard it, because it not only contains the development of the enterprise, but also contains huge political achievements.

In particular, the scene of a row of glossy imported machinery is something that anyone should be moved by, and it is precisely because of this that Liu Wenzheng will choose Liao Yongchen, and he is as experienced as Liu Wenzheng, who has given it a go for the sake of his political achievements, can't Lu Jiadong? You must know that Lu Jiadong is a high-ranking cadre now, and his political achievements are equally important to him, so when Lu Jiadong's face was as usual and he didn't say a word, Tong Wenlie's heart couldn't help but chuckle...........

For Tong Wenlie's thoughts, he naturally couldn't escape Lu Jiadong's dark and clear eyes, and immediately waved his hand, and comforted with a smile:

"Don't worry, Professor Tong, although I am not proficient in the matter of the projectile body, but I also know a little about it, this kind of high-precision casting, can not be produced by mechanical processing at all, can only be manufactured by sand casting process, for this, I still understand........."

Lu Jiadong did not tell a lie, he did have some understanding of the processing technology of the missile body, after undertaking a long-range air defense missile project of the army, he visited the missile manufacturing factory with the chief technician in charge of production at that time, and the most surprising thing to him was that such an advanced missile actually has an important link that requires the most primitive manual manufacturing;

And this link is nothing else, it is the projectile casting, but unlike the traditional mechanical mold, the projectile casting is the use of sand casting, one to produce the cost is relatively low, and the sand is well shaped, you can shape the complex structure in the projectile body according to the need, which is convenient for one-time molding.

However, if you want to get qualified castings, the requirements for sand, the fineness of the configuration, and the integrity of the molding have extremely high requirements, and these can not be completed with the help of machinery, and can only rely on the casting mechanic to use a pair of hands and a few shovels, little by little to complete by hand, it can be said that the sand mold casting mechanic is like a brilliant artist, with a grain of sand to carve out the outer coat of the missile..........

Seeing this at that time, Lu Jiadong was very surprised, it was hard to imagine that in the highly developed 10s of the 21st century, it was still necessary to complete the manufacture of advanced missiles by hand, but the next sentence of the chief craftsman made him remember it for life:

"Even in precision machinery, there are things that can't be done, and only dexterous hands are infinitely possible.........."

It is with this experience that Lu Jiadong has a deep impression of the casting and processing of missile bodies, so when he listened to Tong Wenlie's words, he did not feel that there was anything wrong with using the most traditional method like others, but he thought it was true, Tong Wenlie listened to Lu Jiadong's words, and a hanging heart finally let go, and his solemn face finally smiled with satisfaction at this moment, and nodded to Lu Jiadong:

"I know, Mr. Lu, you are an understanding person, alas....... To be honest, there are really not many people who can know how to do things like Mr. Lu these days, it's a pity.......... If Secretary Liu and they could have half of Mr. Lu's ability, they wouldn't have to engage in so much useless equipment..........."

"Put the equipment in advance, the top priority, or to solve the problem of the air defense missile system, sand casting is simple, but the requirements for casting technicians are very high, the proportion of sand, temperature control and the fineness of the casting mold, are not ordinary people can compete, if the technician is not good, even if we know where the problem is, it is helpless........."

"Mr. Lu, you are really an expert, and you immediately said the crux of the problem!"

Tong Wenlie gave Lu Jiadong a thumbs up, and then said with a meaningful smile: "At this point, I think you should go to our foundry to see it in person, and then you will know why I stick to traditional craftsmanship..........." (To be continued.) )
