The Rise of the European Emperor

After thinking of these techniques, Marin hurriedly wrote them all in a notebook, and then went to the forging base near Lyle City in the south in person, and asked the craftsmen to cooperate, try new methods, and forge new types of sabres.

Of course, first, Marin asked the steel mill to get a batch of medium carbon steel bars. Then, let the craftsmen who are responsible for making the sword forge the saber.

It is not difficult to make medium carbon steel strips, because the medium carbon steel produced by Marin's steel plant has undergone secondary refining and has been cleaned by slag-forming agents, so there are few impurities in the steel strips, and there is no need for The oriental craftsmen used thousands of hammers to knock out the impurities inside.

For the knife maker, all they have to do is hammer the medium carbon steel bar into the shape of the blade. The process of beating is also the process of making the steel itself tighter. In later generations, in order to forge qualified aircraft wings, it is even necessary to use a hydraulic press of tens of thousands of tons to violently forge the aluminum alloy wings to make the wings strong enough. Otherwise, if the wing strength is not enough, it will cause the wings to fall off when the aircraft is flying...

Therefore, to make knives, the forging process is essential. Because, the process of forging can make the sparse structure of the steel inside the original casting more compact and enhance the performance.

Here I have to mention the difference between casting guns and forging guns. Have you seen Hongyi Cannon? The wall of the tube is so thick that it is very heavy at first sight... That is the reason why the ancient steel technology was backward and never forged. Regardless of the thickness of the barrel wall of the ancient cannon, the pressure it can withstand may not be as large as the barrel of the later generations with a thinner wall.

The rise of the German Empire relied on Krupp's steel cannons. The reason why Krupp's artillery is so powerful is that Krupp's artillery is a forged cannon and can withstand a large chamber pressure. Before the Franco-Prussian War, forged steel guns were rare. In the American Civil War before the Franco-Prussian War, the main artillery, the Napoleon cannon, was a typical cast cannon.

For Krupp's artillery, a large-tonnage forging press was used to forge the steel column violently, which made the internal crystal structure of the steel more compact, and at the same time, the ability to withstand chamber pressure was greatly increased.

After the steel column was almost forged, Krupp began to drill with the drilling rig. Although it became difficult to drill holes in the forged steel column, the resulting gun barrel had greatly improved chamber pressure resistance. Also, artillery can be made lighter. Otherwise, if casting is still used, it needs to be as thick and cumbersome as the Hongyi cannon...

Then, the French army, who still used cast guns, was beaten by the Krupp forged guns of the Prussian army... Then, forged guns became popular in Europe, while cast guns withdrew from the stage of history...

...

In order to improve the metal properties of the blade and plate armor, at the beginning, the steel bars were actually sent to the hydraulic forging hammer over the artificial reservoir for strong forging. Then, the medium carbon steel bar that has been forged by the hydraulic forging hammer will be hammered by the casters with the blacksmith's hammer to adjust the shape. After all, hydraulic forging hammers are rough and sometimes smash the bars too far. Therefore, it is necessary for the blacksmiths to readjust the form by heating and forging...

With the forging of the swordsmiths, the steel bar was beaten more and more like a knife...

When the blade body is basically formed, it is the carburizing stage. Malin specially brought fermented fermented soybean paste made from soybeans produced in the Americas, combined with charcoal and soil, and started the process of solid carburizing on the surface of the blade known as the "steel-steel method"...

After several hours of simmering in the crucible, Marin felt that the carburization was almost there, and then the salt quenching and oil quenching began.

Salt-quenched Marin still uses horse urine. After all, although it is salt-quenched, Marin does not know whether there are other ingredients in horse urine that are beneficial to swords. Therefore, when the salt was quenched, Marin directly used horse urine, but in order to enhance the effect, he also added table salt to the horse urine, so that the concentration of salt was higher and the effect was enhanced.

As for oil quenching, it must be the inedible whale oil. That thing Malindo, it doesn't feel bad to use. Now, there are five whaling teams on the Newfoundland side, which regularly hunt whales. If it weren't for the Marlins limiting their kill count,

It is estimated that those whaling teams can kill knife whales every day. After all, there are very few whale-killing fleets in the world now, and the Newfoundland fishing grounds are so rich in fishery resources that there are many whales eating small fish here, and they can't catch them all...

...

After a lot of hard work to get a beta version of the new saber, Marin couldn't wait to take it to the guards to test the effect. This time, there are three new-style sabers, one for slashing with high carbon steel sabers, and the other for slashing with the ordinary European iron knife brought by this grandma...

As a result, Marin was pleasantly surprised to discover that the complexly processed new saber was truly extraordinary...

The result of cutting with the high carbon steel saber was that the high carbon steel knife was broken, but the new saber was cut with a gap. After all, high carbon steel knives are inherently very hard... When slashing, the high carbon steel knives are easy to break, but the new saber bounces back after bending, and it does not break, but is hardened by the high carbon steel knives. The blade cut a gap.

And against the traditional European iron knife, it is naturally a complete victory, completely crushed. The new type of saber not only chopped off the ordinary iron knife, but it was only chopped with a scratch-like mark...

...

After testing, the new type of saber retains the advantages of the old-fashioned high-carbon steel knife with high blade hardness, but at the same time, the toughness of the blade is greatly enhanced. Slashing with a high-carbon steel knife, they can win. In the face of those iron knives in the modern era of Europe, it is naturally not to mention.

Kahn, who was in charge of the test, suddenly lit up and grabbed the third untested saber as his own saber. After all, for generals, a treasured sword is very attractive.

Marin shook his head, he didn't grab the knife from Kahn. After all, this new type of saber, strictly speaking, is just a low-cost compromise product.

In fact, if Marin wanted a treasured sword, he could send someone to Japan to hire a senior swordsmith to use the stack forging method to create a new type of treasured sword.

What's more, the natural pattern steel Uzi steel in India has not been discontinued yet. If you want a treasure knife, go to India to buy a batch of Uzi steel and come back.

"Oh, I almost forgot, I sent a fleet to India this time, so I can buy some Uzi steel!" Marin patted his head, and quickly sent someone to inform Draka, the trade representative who was preparing to go to India, and ordered him to be there. After going to India, I purchased a batch of natural patterned steel Uzi steel, and then used it to make treasured knives.

Natural Uzi steel, coupled with Marin's advanced carburizing and quenching methods, will definitely be able to get a high-level sword...

Of course, the sword made of Uzisteel must be the welfare of Marin and the noble officers. As for ordinary cavalry, it is still a new type of saber specially treated with medium carbon steel. Anyway, it is much stronger than the ordinary iron knife in Europe. Moreover, in the face of high-carbon steel knives, you can also fight. Even high-carbon steel sabers, compared to the iron knives of this era in Europe, can be considered treasure knives...
