Chapter 1173: change

At this time, everyone in the room looked at Tan Zhenhua in a world that was far different than they were at the beginning.
To be honest, although Tan Zhenhua is well-known all over the world, most people are just hearsay about his deeds, knowing that he has money, is the youngest tech rich in Silicon Valley, recognized as the richest man in China, in just a few years Time has been earned for Jinshan Yinhai, which cannot be spent in a few lifetimes... But how high is Jinshan, how deep is Yinhai, how he earned it, and which projects he has invested in, that’s totally divided. A variety of unreliable interpretations are flying all over the sky, and they are also the favorite gimmicks used for hype and drainage in railway stations, bookstores and other places where literature gathers.
For example, one of the most widely circulated rumors in the market is that the reason why he was able to make a fortune so quickly was because after studying in the U.S., he was favored by the only daughter of the oil king Rockefeller, but the old man was not at first. Agreed, so he was tested in the Western Heavens, hoping to persuade him to retreat on his own, but after all, Tan Zhenhua passed the tests with his own wisdom and perseverance. At the insistence of his only daughter, the old man finally reluctantly admitted the reality, Tan Zhenhua embraced the beauty, and the old man gave a banknote printing factory as a dowry...
To tell the truth, when my mother saw this so-called "documentary literature" from nowhere, and called eagerly to ask the authenticity, Tan Zhenhua was stunned...
Although he himself didn’t bother to pay attention to these legends of stalls, it is undeniable that the spread of these stalls still had a certain impact on many passers-by who were not familiar with him. An attitude of suspicion, but subconsciously accepts such a very reasonable inference: Without a special chance, Tan Zhenhua could not be as successful as today, and this special chance is the most reasonable and attracting the most attention. Of course, the explanation is that something between men and women.
Therefore, in many people’s after-dinner conversations, Tan Zhenhua’s achievements today are entirely out of luck, but the term fluke is basically a negative in the perception of most scientific researchers, especially the old-school researchers in China. The vocabulary of the attribute.
Therefore, when Tan Zhenhua walked into this conference room, the first time he was greeted by him was definitely not a warm applause. It was not so much to welcome him, it was not to give Minister Li a face, and to be satisfied by the way. Take a look at their curious psychology and see what makes this legendary lucky boy different from ordinary people.
But now it is different.
Although everyone still has doubts about the origin of his huge wealth, the information just revealed still shocked them, or shocked!
A piece of artillery steel, starting from ore smelting, until it becomes a qualified barrel blank, has experienced the core, most important, and most technically important links during the period. Tan Zhenhua's companies actually participated in it-no, say Participation is really not enough to describe. It should be said that if Tan Zhenhua is willing, he can do it all by himself as long as he spends a little effort!
Can this be explained by luck?
But if it was not a fluke, how could he, a young man like him, set out to lay out such a basic industry such as scientific research-mining-metallurgy-forging a few years ago, complex, huge investment, and slow-effective Industry chain?
This is not the time to learn more about these things. Zhu Yusen could only temporarily press his chaotic thoughts, coughed lightly, restored the silence in the conference room, and then began to continue his narration.
"The forged body tube blank, the next step is of course machining," he said slowly: "That is to take out the barrel from this solid blank. Anyone familiar with the machining process knows this. It’s a real problem."
Following his words, Tan Zhenhua found that many people in the room were nodding their heads. Also, everyone sitting here was playing tanks. No matter what sub-systems they were in charge of, they all knew about machining after all. Even this major.
Well, it is estimated that you are a layman in this room—in fact, it is not a complete layman. As far as machining is concerned, Tan Zhenhua in his previous life has a considerable understanding of this, because as long as it is a radar, it cannot be separated from heat dissipation. The heat dissipation of the radar requires a very complicated precision mechanical system, and naturally it cannot be separated from the processing technology.
So he knows the difficulty of the barrel processing-a steel column with a length of more than 5 meters and a length of 6 meters needs to be punched in it. This typical deep hole processing is simply a nightmare for the producer!
Moreover, the precision requirements of this deep hole are particularly high, which is a nightmare in a nightmare!
The so-called "deep hole" refers to the hole whose length to diameter ratio is greater than 5. (Why deep hole processing is difficult? Qianzhiyu will not explain it here, lest everyone talks about hydrology, and interested students ask about it. Mother.) If the aspect ratio is greater than 5, it is called "deep hole", which is listed as "one of the most troublesome problems in machining", but the barrels of tank artillery are generally more than 50 times the diameter, "Storm 2 The gun on the number is 58 times the horrible diameter!
This is difficulty!
And you don’t just have to punch a hole, you have to draw the rifling after you have finished the rifling, you have to polish it, you have to polish both inside and out, dear, the requirements inside are higher, dear, they are all deep holes Homework, dear...
Therefore, it seems that artillery with a very simple structure is really not something that ordinary countries can play. The country in the world that can really produce artillery on its own is by no means more than two hands!
Do not believe? Look at the next door, Ah San, that is also the world’s 8th strong presence in GDP. It claims to be able to produce
advanced weapons
such as the
K9
self-propelled artillery and the
Aqiong
main battle tank. But goose, unfortunately, these goods All of the gun barrels are imported!
Well, there is a more funny chestnut:
In the mid-1980s, Sange took a fancy to the Swedish Bofors FH-77B 155mm towed artillery. This gun was very advanced in performance at the time. The maximum range for launching ordinary concave grenade was 24 kilometers. The maximum range of the full-bore bottom row grenade reaches 30 kilometers.
Because of the good performance, the third brother introduced 410 in one go, with a unit price of 3 million US dollars. (It can also be seen that a good gun is really not cheap. It was 3 million US dollars in the 1980s. I bought China’s You can buy 6 tanks for 59 tanks. Buying "F-7" is enough for one and a half!) This big business of more than one billion US dollars was also a sensation at the time, and it was a record.
Of course, the ambitious third brother will not just be satisfied with "buy, buy, buy", "Made in India" is its ultimate goal, so when he bought these artillery, he also introduced a production license. And started the imitation process of localization. According to the usual practice, the third brother gave this future military weapon the name of a legendary hero-"Danush" heavy howitzer.
With all the technical data on hand, how long does it take to fake a gun?
Third brother's answer is: 30 years.
Thirty years later, on a sunny day in 2016, the result of the imitation of the third brother, the "Danush" heavy howitzer with a localization rate of 81% was finally pushed onto the shooting range and started its first live ammunition test. , And established a marvelous skill in the first shot-10 down in one shot!
It blows up, it blows up, it blows up!
The entire test team will be reimbursed!
There must be someone to take responsibility for such a big accident. Of course, for Sange, there is one and only one person behind this kind of thing-so the accident investigation report is written like this: After careful inspection, it is Huaxia. There is a problem with one of the parts produced, and all the responsibilities should be borne by the Huaxia Enterprise that produced this part!
A village and township enterprise in China with a population of less than 20: "...What's the special thing about your artillery bombing a bearing factory? And have you bought the goods with me? Why don't I remember that I signed this order? Hello, Brother San, you didn't buy the second-hand disassembled and refurbished goods from our factory, did you?!"
...
"The artillery barrel is difficult to machine and has a high scrap rate, which is also an important reason for its high price. In almost every aspect of processing capacity, processing accuracy or processing efficiency, we are far behind Western developed countries in almost every aspect." Zhu Yusen said with some helplessness: "It's a little bit close here, a bit close there. Add up, it's a far cry."
