Chapter 233 Export to Domestic Sales
"Old Wang, what's the matter?"

Seeing that the leader of the army called Lao Wang suddenly showed an unbelievable difference, the leaders of several troops immediately surrounded him.

Even the head of the leader's gaze was imperceptibly cast on the troop leader named Old Wang.

The reason for this is very simple. As a senior technical cadre at the headquarters, Lao Wang has deep attainments in the field of military product technology and craftsmanship.

It is also because of this that although Lao Wang was surprised by the development and technical background of Zhujiang factory since he came to Zhujiang factory, he is far less exaggerated than others.

Because in his eyes, the Zhujiang factory is only fast, and there are not many advantages in terms of technology, it is nothing more than the superposition of many mature technologies.

For example, the DPZ-82 82mm recoilless artillery that I saw before, although it is very novel, it is not a new equipment, let alone a new technology.

Can't other domestic research institutes and manufacturers come up with it?
If we pay close attention and have a clear overall plan, it is easy to do it first, but it will consume a lot of funds and weaken the progress of other key projects.

After all, it is still a question of funding, a matter of money.

Because of this, Lao Wang was far less intense than other leaders. Even when he came to the high-end branch factory, he saw 150 computers and DPZ-076 76mm naval guns.

Lao Wang also felt that this was due to the solid foundation of Zhujiang manufacturers.

Until he saw the wet bores at the end of the DPZ-076 76mm naval gun, his attitude immediately took a 180-degree turn.

Seeing the leaders of other troops coming up, Lao Wang pointed to one of the bores and said, "Look at this bore, and then look at the structure of the entire barrel..."

The army leaders who came up were stunned by this sentence, and said to themselves that if I can see it, there is no need to ask you here, Old Wang?

Fortunately, Lao Wang didn't give a damn, and continued: "This gun barrel is made of a double-layer tight manufacturing process, which was born at the end of World War I. This process was commonly used in large-caliber artillery on battleships during World War II. The inner barrel is cast first, and then the outer layer is cast. The double-layer structure can not only offset each other's own stress, but also increase the service life of the barrel.

However, with the development of modern artillery manufacturing technology, especially the application of barrel self-tightening technology, this kind of old-fashioned technology has gradually been eliminated. "

"It's nothing to say..." Hearing what Lao Wang said, a military leader snorted coldly, and teased Lao Wang: "Why are you so surprised, Lao Wang? It's scary!"

"I'm not amazed at the reappearance of this old-fashioned craft, but am shocked by their innovation in this craft!" Lao Wang quickly explained.

"What innovation?" a leader asked.

Lao Wang hurriedly pointed to the four bores about one centimeter wide between the inner layer and the outer layer: "They pre-buried the cooling system in these bores, so..."

Before he finished speaking, Pharaoh looked up at his colleagues with complicated eyes: "That's why they made the cannon so lightly and dexterously, and the key point is here!"

"Isn't it just to make a bore in the middle of the gun barrel? What's so difficult about it?" Another troop leader looked at Lao Wang.

Lao Wang shook his head: "It's really not difficult to bore the groove, but the difficulty is to drive such a groove all the way to the muzzle..."

When he said this, Lao Wang's eyes extended from the tail of the gun barrel to the muzzle. You must know that the DPZ-076 76mm naval gun is a long-barreled naval gun with a caliber of 62 times.

The barrel exceeds 4 meters.

For such a long distance, it is necessary to open a boring slot between the two layers of the barrel, and there is no equipment that can detect the internal situation during the entire processing process.

Not only that, the entire process must not have the slightest error, otherwise the entire gun barrel will be completely scrapped.

That's all, the key is to maintain the strength of the entire gun barrel at an extremely high level during the processing process. After all, a boring groove is made in the middle of the outer wall of the gun barrel. If the strength of the gun barrel is not enough, even if the processing link can support It's worth it, and the operation link after the deployment of troops will also be damaged because the gun barrel cannot withstand the high temperature and high pressure of the shells.

Therefore, extremely high requirements are put forward for materials, smelting and process requirements.

It is no exaggeration to say that Zhujiang Factory has strong strength in special steel, machining, and system integration from just such a gun barrel.

This proves that what Wen Dawei said was true. Even if the technology is made public, developed countries in Europe and the United States really can't make it, because the key to this thing is not the technology, but the actual manufacturing and craftsmanship.

As the saying goes, don’t do porcelain work without diamonds, that’s exactly what it says!

What the Zhujiang factory has, the developed countries in Europe and the United States don't have it, so we can only watch it!

It is precisely because of this that Lao Wang was so shocked, because he never expected that Zhujiang Factory is not only powerful in theory, but also superior in manufacturing and craftsmanship!
So after explaining to the leaders, he looked at Wen Dawei again and asked what he said before: "How do you do this boring?"

"We use the professional equipment developed by ourselves, the JJZ-406A CNC boring machine, which can not only process the barrel of the artillery, but also the precision boring groove. Of course, if you want to process this aspect, the material requirements are It is very harsh. It is necessary to add some rare earth elements to the smelted molten steel, and then go through electroslag remelting, a layer of tube-saving self-tightening, and a double-barrel self-tightening gun barrel to make such a cooling tank..."

Wen Dawei explained in detail, but he sighed while talking: "But because of this, our artillery barrel accounts for 65% of the entire production cost, which makes the research and development budget of the current DPZ-076 76mm naval gun very serious. Overspending, the unit price may be 25% to 50% higher than the previous quotation to Bosnia!"

"Oh? How much is it estimated?" At this time, a leader from the Navy couldn't wait to ask, obviously he was very concerned about the price.

Wen Dawei rubbed his chin, and pondered for a while: "Um... It costs about 25 US dollars a door, and the matching ammunition is not included!"

"25 U.S. dollars?" The naval leader immediately opened his mouth wide when he heard the words, and then the corners of his mouth turned up, his facial muscles bulged, and he showed a very happy smile: "It's so cheap, less than 200 million yuan, the chief's cannon is so expensive ~~~"

When speaking, the head of the navy looked at the leader, who also nodded slightly: "25 US dollars is indeed not expensive..."

Then he looked up at Wen Dawei: "Comrade Dawei, what is the annual production capacity of your naval guns? If the army orders in large quantities, is there any discount on the price?"

Wen Dawei froze for a moment when he heard the words, what's the matter? The DPZ-076 76mm naval gun will be exported to domestic sales?
