C2508 The Secret of Krupps Cannons (2/2)

However, in the modern sense, the classification of steel and iron is not simple. It is distinguished by the amount of carbon in the metal.

Iron, which contains less than 0.2% carbon, is named iron in academia, while wrought iron, which is above this index, is called steel.

Why did the ancient times require thousands of forgings and burns to make excellent weapons? The purpose was to allow more iron to come into contact with the charcoal, allowing the burning carbon to seep into the iron and obtain the steel.

Ancient China's method of stir-frying steel was actually also to uniformly mix the iron shavings and charcoal together. Then, after a fierce fire in the furnace, the carbon element in the charcoal gradually seeped into the iron shavings, finally obtaining high-quality steel.

The starting magical equipment of the Krupp family was called canned steel. As the name implied, it was made from a steel jar, in which pig iron and wrought iron were placed, and various chemical trace elements were added.

The principle behind this was no different from Ancient China's Eroding Steel. It could only be used to open fire and turn it into a furnace for the smoldering samples!

This way, the steel would have stronger toughness and strength. When used to make cannons, it would also be tougher.

As the steelmaking technique was the top secret of the Krupp. That was why the breeches produced by the Krupp were the best in the world, and had completely abandoned the bronze material.

When Krupp heard this, her hands were trembling like a sieve. At that time, he even had the illusion that if he had a gun by his side, he would definitely pull the trigger and kill this man who knew the core secrets of her family.

Although Xiao Letian's words were general, but it was to the point that the secret of ironing steel was revealed! The production principle was pointed out.

”No, no, no …” It's impossible. How do you know about the secret of the steel? This is the highest secret of our family! ”

Xiao Letian laughed coldly, ”You don't have to worry how I found out. You have your secrets and I have mine as well. It's best if we don't interfere in each other's affairs …”

Let me talk about this next, how did you solve the problem of the leakage of the cannon's tail flame? Although I am currently unable to produce ready-made products, but the way you solve this problem is very clear to me.

You have only added a small part to the cannon's breech. Its name should be 'Breath Suspending Ring'!

The principle was very simple. The moment the explosive shell's tail was ignited, the high-pressure and high-temperature gas would instantly expand and release its power in all directions.

If the cannon didn't have a closed loop, then these high-temperature and high-pressure combustion gases would spray out from the gap in the cannon's tail, directly burning the soldiers who operated the cannon.

At this time, if one could add an elastic substance to the tail of the cannon, when the cannon's high temperature and pressure suddenly transmitted over, this elastic substance could instantly warp and deform, promptly blocking those gaps.

As a result, the burning high-temperature and high-pressure gas couldn't leak out of the tail part, so he could only change his direction and shoot out from the muzzle.

That way the projectile would naturally get more kinetic energy, which was the secret of the new Krupp cannon, wasn't it?

To tell you the truth, there are already people in the research facility of Ryukyu University who have found the correct answer to this difficult problem! Now they were doing experiments in secret!
