Chapter 888： New Saber (Continued)

Thinking of these techniques, Marin quickly wrote all of them in a notebook, and then personally went to the forging base near Lyle City in the south, let the craftsmen cooperate, try new methods, and cast new sabers.

Of course, first, Marin asked the steel plant to get a batch of medium carbon steel bars. Then, let the craftsmen responsible for making swords forge sabers.

It is not difficult to create medium carbon steel bars, because the medium carbon steels produced by the Marin steel plant are secondary refined and also cleaned by slag-making agents, so there are few impurities in the steel bars. Oriental artisans worked hard to knock out the impurities.

For the die-caster, they only need to work hard to strike the medium carbon steel bar into the shape of the blade. The process of beating is also the process of making the steel itself closer. In later generations, in order to forge qualified aircraft wings, it was even necessary to use tens of thousands of tons of hydraulic presses to forge the aluminum alloy wings violently to make the wings strong enough. Otherwise, if the strength of the wing is not enough, it will cause the wing to fall off during the flight ...

Therefore, the forging process is essential for making knives. Because, the process of forging and pressing can make the loose structure of the steel inside the original casting become tighter and the performance is enhanced.

Here I have to mention the difference between the foundry cannon and the forged cannon. Have you seen the Hongyi Cannon? The wall of the tube is so thick that it looks very heavy at first glance ... That is the reason why ancient steel technology is backward and has not been forged. Not to mention that the walls of ancient cannons are so thick and can bear the bore pressure, it may not be as large as the thinner barrels of later generations.

The rise of the German Empire relied on Krupp's steel cannon. The reason why Krupp's artillery is so powerful is that Krupp's artillery is a forged cannon and can bear a large bore pressure. Before the Franco-Prussian War, forging steel guns was rare. Before the Franco-Prussian War, the American Civil War, the main artillery Napoleon artillery, is a typical foundry gun.

Krupp's artillery first used a large-tonnage forging machine to forge the steel column violently and freely, so that the internal crystal structure of the steel became tighter, and the ability to withstand the pressure was also greatly increased.

After the steel column was nearly forged, Krupp began drilling with the rig. Although the drilling of the forged steel column became difficult, the resistance of the obtained barrel to the pressure of the barrel was greatly improved. Moreover, artillery can also be made lighter. Otherwise, if you use casting, you need to make it thick and heavy like the Hongyi Cannon ...

Then, the French army, which still used casting cannons, was beaten by the Krupp forging cannon of the general army ... Then, forging cannons became popular in Europe, and casting cannons withdrew from the stage of history ...

...

In order to improve the metal performance of the blade body and the plate armor, the steel bar was actually sent to the artificial water reservoir under the hydraulic forging hammer for strong forging. Then, the medium carbon steel bar forged by the hydraulic forging hammer will be beaten by the casters with a blacksmith hammer to adjust the shape. After all, the hydraulic forging hammer is very rough, and sometimes it will smash the steel bar too much. Therefore, it is necessary for the blacksmiths to reshape the shape by heating and forging ...

As the casters forged, the steel bars were beaten more and more like knives ...

When the blade is basically formed, it is the carburizing stage. Malinte brought his own fermented soybean sauce made from soybeans produced in the Americas, combined with charcoal and soil powder, and began the process of solid carburizing on the surface of the blade called the "steel method" ...

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

Salt-quenching Marin still uses horse urine. After all, although it is salt-quenching, 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. However, in order to enhance the effect, he also added table salt to the horse urine to make the salt concentration larger and strengthen the effect.

As for oil quenching, it must be whale oil that cannot be eaten. That stuff Malindo doesn't feel bad to use. Now, there are five whaling teams on Newfoundland, and they often kill whales. If it were not for Marin to limit their number of kills, it is estimated that these whaling teams could kill sword whales every day. After all, there are very few fleets to kill whales in the world, and Newfoundland fisheries are so rich in fishery resources. There are many whales eating small fish here, and they ca n’t be caught ...

...

After painstaking efforts to obtain a new version of the saber, Marin ca n’t wait to test the effects of the guards. There are three new-style sabers created this time, one for cutting each other with high-carbon steel sabers, and the other for chopping with this grandma with a common European iron knife ...

As a result, Marin was surprised that the new-style saber now undergoing complex processing was really extraordinary ...

The result of chopping with the high-carbon steel saber was that the high-carbon steel knife was broken, but the new-style saber was cut out of the gap. After all, the high-carbon steel knife itself has a high hardness ... when cutting, the high-carbon steel knife just broke easily, and the new military knife bounced back after bending. After all, it was not broken, but it was hard The blade cut a gap.

And chopping against traditional European iron knives is naturally a great victory, completely crushed. The new-style saber not only cut off the ordinary iron knife, but also only got a scratch mark ...

...

After testing ~ www.novelhall.com ~ the new army knife retains the advantages of the old high-carbon steel knife with high blade hardness, but at the same time the blade toughness is greatly strengthened. Chopped with a high-carbon steel knife, you can win. In the face of the iron swords of the current European era, it goes without saying that.

Kahn, who was in charge of the test, suddenly brightened his eyes and snatched the third untested saber as his saber. After all, a treasure sword is very attractive to the generals.

Marin shook his head, he did not grab the knife with Kahn. After all, this new saber is, strictly speaking, a low-cost, compromised product that is widely used to pack cavalry and is not a fine product.

In fact, if Marin wants a sword, he can send someone to Japan to hire a senior caster to create a new sword for him.

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

"Oh, I almost forgot. I sent the fleet to India this time. I can buy some Uz steel!" Marin snapped his head and sent someone to notify the trade representative Draka who was preparing to go to India. After going to India, I purchased a batch of natural pattern steel Uzi steel and used it to build a treasure sword.

Natural Uzi steel, coupled with Marin's advanced carburizing and quenching methods, will inevitably be able to obtain high-grade swords ...

Of course, the sword made by Uzi Steel must be the welfare of Marin and the noble officers. As for ordinary cavalry, it is a new 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 can be regarded as treasure knives compared to the iron knives of Europe in this era ...
