His brows were furrowed!

When he put the cigarette butt out in the ashtray, Zhu Guoqiang couldn't help but let out a long sigh.

Standing in the company's office, staring at the suppliers displayed on the computer screen, his mood seemed dull.

"Otherwise, how about entrusting several more companies to manufacture it?"

What is manufactured is not other things, but artillery. Of course, it can only be purchased in the name of "props" or "decoration". But it doesn't matter if you purchase dozens of them, you can purchase hundreds of them... Just kidding, this is for you

Send yourself to the bureau!

"After the Qing army is defeated, the first thing to do is to build a military factory!"

Once again, Zhu Guoqiang said to himself solemnly.

In fact, he was not idle in the eight months after the Qing army withdrew. The hydraulic factory built next to the Wang Tomb for the purpose of making tools could not only make armor and various cold weapons, but also gunpowder.

, paper shells, bayonets, artillery shells, even grenades and other weapons. Although raw materials such as flash caps need to be "processed with supplied materials" here, at least a preliminary military industry has been established. Many people have been trained

Workers and industry can only start everything step by step.

As for artillery manufacturing... that is restricted by raw materials. The iron smelting plant in Jinan can only provide white cast iron. This kind of cast iron cannot be machined, so the barrel cannot be ground. In contrast, the industry here

The performance of the artillery provided by the society is as good as that of the "Zenith Star" technology. And it is so cheap. It is almost like exchanging a high imitation plate for a cannon, which is only a few cents.

Anyone would be willing to use a better one! And it’s ridiculously cheap.

But the problem is...the quantity!

There is indeed a huge industrial production capacity here, but if you want to use all this to make weapons, you are basically challenging the powerful organs of the country. A few props and dozens of decorations are possible, but hundreds of "decorations" are really big.

It's an insult to IQ. Even if you run your own factory, you will be reported by workers every minute. If you call a rogue gas station, you will be rewarded 30,000 yuan! For making weapons... at least the bonus will start at 100,000 yuan!

"The power of the rising masses cannot be underestimated!"

While talking to himself, Zhu Guoqiang continued to flip through the pages. Suddenly, his attention was attracted by one of the pieces of information.

"Scrap the train axle!"

Staring at the appearance of the axle, there were some changes in its appearance in his mind, and it seemed to overlap with the barrel of the artillery. Zhu Guoqiang's eyes suddenly lit up, and he hurriedly picked up the phone.

"Hey, Old Han, I have an order for you to confirm. 300 train axles. Yes, if the price is right, just take it!"

Train axles may not look like much, but decades ago, the arsenal in the base area used them to make artillery. Even during the Liberation War, the arsenal also used it as raw material to mass-produce mountain cannons. The steel used for axles is definitely no better than ordinary steel.

gun steel difference.

Since our ancestors can do it, of course we can do it too!

"Look at the drawings. First, a lifting ring is milled out at the tail, then the inner hole is ground to 115 mm, and the tail is reduced to 90 mm..."

In the office of the metal processing factory, Zhu Guoqiang pointed to the drawings and explained the "mechanical components" he needed to process.

He does not need to explain the purpose of the components, he only needs to provide drawings. In modern industrial society, even the best experts and scholars cannot grasp the purpose of all mechanical components, not to mention that there are new mechanical components every day

Put into production.

"The swing axis of the tube body needs to be seamlessly welded. It is a stress-bearing part and the strength must be guaranteed. Is that okay?"

The so-called "swing axis" is the lug, which here is just a component of the mechanical component. Seamless welding technology can ensure the strength of the connection between it and the gun barrel.

But it's definitely not an artillery piece, and no one would have thought it was!

But it is an artillery piece, and it is a twelve-pounder cannon, but its caliber is 115 mm, which is 2 mm less than the 12-pounder cannon, but this has no effect. The diameter of the twelve-pounder cannon's shell is only 110 mm.5 mm.

Not only is the clearance sufficient, it can even improve its range and accuracy. After all, the clearance becomes smaller, and the air-holding performance is naturally better.

"Of course, no problem, three days. If you need it urgently, two days, do you think that's okay? But in terms of price... In this way, I will only charge overtime pay."

The boss of the factory simply gave a suitable price. After doing business for so many years, why didn't he realize that this must be a big project, processing 600 "cylinder liners" at once, even though he didn't know its purpose?

, but if this business is successful, there will definitely be room for cooperation in the future.

However, it only took an hour for Zhu Guoqiang to finalize the order for the "artillery", no, it was for mechanical parts.

"The length of a train axle is 2180 mm, the maximum diameter of the tail is more than 220 mm, and the diameter of the shaft body is 170 mm. The caliber of the gun is 115 mm... The wall thickness of the barrel is 27.5 mm. Remove the tail and cut it into two, and the barrel length is 1.05

Meter, the 12-pound mountain grenade gun has a body length of 38 inches and a wall thickness of 1.5 inches. Well, the length exceeds ten centimeters and the wall thickness is thinned...that is, less than 11 millimeters, but it is forged from alloy steel and the materials are more advanced.

, The allowable compressive strength of general cast iron is 200mpa, and bearing steel is at least two or three times that. It will definitely be no problem to thin it out by this small amount. Not only is there no problem, it should also be able to withstand higher manufacturers..."

On the way back, Zhu Guoqiang still kept comparing the data of the two gun barrels in his mind. Considering the size of the train axle, he deliberately chose the 12-pound mountain howitzer as the prototype of the artillery. Although it was a mountain howitzer,

It's not impossible to use it as a naval gun. After all, most of the ancient Chinese ships were single-layer ships, with a thickness of only three inches, or ten centimeters. Sea-going ships like the ocean-going ships sometimes added a layer of one foot.

Five thick shipboards, even so, what's the harm?

Shooting it with twelve pounds of mountain grenade would even be a waste of firepower.

While waiting for the traffic light, Zhu Guoqiang looked back at the two "cannon barrels" behind the car and said to himself.

"The barrel of the cannon is now finished. Should we go and try the cannon? Yes, we have to go and fire the cannon first!"

Shooting, no, trying out the gun!

Of course, it cannot be tested here. It must be taken to the other side for testing. The test was conducted on the embankment of the Yellow River outside Taoyuan County. Since it was just to test whether the artillery could be used, Zhu Guoqiang directly put the barrel of more than 100 kilograms into it.

It is temporarily installed on the mount of the twelve-pound Napoleon wheel gun. The lug diameters of the two are the same. After simple modification, it is also suitable.

Chen Wudi and others seemed a little skeptical about this "small" artillery.

"My lord, can it really hit a nine-pound cannonball?"

Nine-pound cannon is their name for twelve-pound cannon. One pound in the Ming Dynasty weighed 596.8 grams. The difference between twelve pounds and Mingjin is not just over 9 pounds. But nine-pound cannon is a big thing. It is so small and can be fired.

Nine pounds of cannonballs?

"That's right!"

Zhu Guoqiang nodded and said with a smile.

"It's just that mounting it on a field gun mount is a bit overkill. We can replace it with a new type of gun mount later, which can be used as supplementary firepower for the twelve-pound field gun. After all, it is lighter."

Not only is it lighter, if it is replaced with the mount of a 12-pound mountain howitzer, its weight is not even as heavy as the mount of a 12-pound field gun. This guy is definitely a weapon for marching and fighting in this era.

While Zhu Guoqiang was speaking, the gunners had already pointed the muzzle at the unfolded hard sail of a small sampan on the river. After a simple aim, the gunner stuffed the reduced gunpowder bag from the muzzle, and then stuffed the solid bullet into it, and fired with

After the bullet-passing rod is compacted, the gunpowder bag at the bottom of the barrel is pierced through the ignition hole, a match rope is inserted, and then the gun is ignited and stepped back a few steps.

Amidst the "sizzling" sound of the ignition rope, the match quickly burned out. Two or three seconds after a puff of white smoke came out of the ignition hole, there was a "boom" sound and a cloud of smoke spewed out from the muzzle.

Zhu Guoqiang shouted when the cannonball accurately hit the hard sail set up on the sampan a hundred meters away, punching a hole in the sail and roaring to the other side of the river.

"Double the gunpowder to 12 taels a penny!"

Twelve taels a penny!

That is one pound in weight. Historically, due to the thickness of the gun body, the twelve-pound mountain grenade could not withstand too high a chamber pressure. When used, it was generally loaded with only 0.5 pounds of propellant, which was only half of the twelve-pound howitzer.

One-fifth of the two-pound Napoleon cannon, so the range is naturally shorter.

However, after repeated calculations, Zhu Guoqiang felt that his twelve-pound mountain grenade should be able to meet the standard of a twelve-pound howitzer. After all, its barrel is made of high-quality bearing steel of the 21st century, and its barrel strength is fully adequate.

Withstand the chamber pressure of 454 grams of propellant!

The result was just as he expected, high-quality "gun steel" could fully withstand higher chamber pressures. With the sound of a gun, the shells roared out of the barrel again, and then Zhu Guoqiang ordered again.

"Double the propellant!"

Later, it was just to test its chamber pressure, from twelve taels per cent, to twenty-four taels per cent, to forty-eight taels... Finally, with a loud noise, the barrel finally burst, until this

At this time, Zhu Guoqiang nodded with satisfaction, then turned to look at the stunned people, and asked with a smile.
Chapter completed!
