When Lu Zhishen and Ruan Xiaoer were shocked, Lin Chong held a long knife in his hand that was bright and bright, like a white rainbow in autumn water, and he was also amazed. Pen "Fun" Pavilion www.biquge.info

The scientific and technological level and technology of the Song Dynasty are advanced.

The wisdom and wisdom of our ancestors should not be underestimated.

Compared with the animal-powered drop hammer designed by themselves, Ye Meng and others not only succeeded in smelting steel in such a short period of time, but also tested and developed qualified high-carbon steel, which is very remarkable.

The animal power drop hammer is a kind of gravity drop hammer, and Lin Chong designed it to replace the blacksmith to strike iron.

And this kind of gravity hammer is much more powerful than the human hammer, many blacksmiths have to hit hundreds of thousands of times to hit the things that can be beaten, and a few times with the gravity hammer can be hit, and more than a dozen strokes can be hit.

In this way, not only can the blacksmith be easier, but the efficiency of ironsmithing can also be increased many times.

Originally, Lin Chong wanted to design a hydraulic drop hammer, but this required a dam to be built by barrage, so he designed this animal power drop hammer.

Although the efficiency of Ye Meng's work has been improved several times or more than ten times, it is actually just a very simple machine, and Lin Chong is also stained with the light of the traverser, this little gadget is nothing to him as a mechanical engineer.

Ye Meng and the others were completely different from Lin Chong, Lin Chong used the ready-made knowledge of later generations.

But Ye Meng and the others pointed in a direction by Lin Chong, talked about some concepts and things to pay attention to, and then the rest was all their own exploration little by little, little by little through continuous experiments, and they specialized in it.

Lin Chong asked himself, if he were himself, he might not be able to make so many breakthroughs in such a short period of time.

But what the effect is, you still have to try to find out.

"Bring a few captured Song Jun hand knives!"

Soon a few Song Jun's hand knives were brought, and Lin Chong took them with his left hand.

I saw that this is the most common broad-edged hand knife of the Song Army, with a blade on one side, sharp in front and wide in the back, the tip of the knife is nearly flush, the thick back blade is thin, the blade is about sixty-five centimeters long, the widest part of the blade is five centimeters, the handle is short, and it can only be held with one hand.

However, the long knife in Lin Chong's right hand is about a meter long, with a slight arc, narrow, sharp, and a little more than two catties in weight, more than a pound lighter than the Song hand knife, much lighter and more agile.

Lin Chong handed the knife to Du Yan and said, "Come!" We cut each other. ”

Du Yan took the knife, and the two nodded in tacit understanding, and then the two knives slashed together.

Hearing a crisp sound, the Song hand knife in Du Chong's hand was cleanly cut into two pieces by the long knife in Lin Chong's hand, but the long knife in Lin Chong's hand was not damaged at all, not even a gap.

"Good! This knife is so sharp! ”

"Haha, it's really a good knife!"

When everyone saw this effect, they couldn't help but praise it loudly.

Victory or defeat on the battlefield depends not only on the command of the generals and the bravery of the soldiers, but also on the importance of weapons and armor, of course, everyone understands.

Before the two knives slashed each other, everyone was still worried that this long knife was so thin and thin; Song Jun's hand knife is so wide and thick, the long knife suffered a big loss, but he didn't know that it was such a result, so he was naturally overjoyed.

"Come again!"

This time, Lin Chong changed to a knife, and Du Yan also took a long knife from the table, and the two knives slashed together again, but the result was still that the hand knife was cut into two pieces cleanly.

"The weapons of the Song army are far worse than the Tang Dao!"

Lin Chong shook his head with a smile, speaking of which, this is still the back of scientific and technological progress.

It turns out that during the Tang Dynasty, charcoal was mainly used for iron processing and forging, and the technology of steelmaking and covering soil was also used, because charcoal had fewer impurities and would not have a bad impact on steel, so the quality of weapons in the Tang Dynasty was very good.

In the Song Dynasty, coal began to be used on a large scale to smelt steel, because the heat of coal was higher, which greatly improved production efficiency; Moreover, the efficiency of the steelmaking process used in the steelmaking method of the Song Dynasty is many times higher than that of 100 steelmaking.

However, during the smelting and forging process, the sulfur in the coal would enter the iron, making the steel brittle, which seriously affected the quality of steel in the Song Dynasty.

This is why the Qingtang Qizi Armor is the best armor in this era, but the Song Dynasty, which has advanced much technology than the Western Xia, cannot make it, because the iron of the Song Dynasty is too brittle, and when it is cold-forged, it will crack after a few knocks, while the Western Xia will not use charcoal.

The Song people didn't know these truths but couldn't hide them from Lin Chong, so after Lin Chong arrived in Liangshan, he asked Ye Meng and them to coke coal first, use coke instead of coal to smelt, and forge steel.

At the same time, he improved the blower to make the oxygen blowing faster and more efficient, and taught Ye Meng and others some principles of steel (iron is soft, carbon is hard, high-carbon steel is hard but easy to break, and low-carbon steel has excellent softness and toughness), and even let him develop high-carbon steel.

Subsequently, because of the use of animal power drop hammer, the efficiency of forging has been increased many times, and Lin Chong instructed Ye Meng to use the method of clamping steel, the core in the middle is made of high-carbon steel with high hardness, and the steel on both sides is made of low-carbon 30 steel, which is soft and hard.

With such a combination of rigidity and softness, the quality of the long knife created is naturally far better than that of Song Jun's hand knife.

And because the quality of the steel is good, the weapons can also be designed to be lighter and more agile, so Lin Chong designed the long knife that everyone sees now according to the style of the cavalry saber of later generations.

"Do you want to try the Uzi Steel Treasure Knife that my brother made in the owner's house again?" Du Yan was very interested and proposed.

Against the world's sharpest Uzi steel treasure knife, Lin Chong was bottomless, but he was still very interested in testing it.

As a result, just now chopping Song Jun's hand knife like chopping waste paper long knife knocked out a big opening, it seems that Uzi steel can not be mass-produced, the world's unique (Uzi steel is only located in ancient India, now a vein in southern Pakistan can be mined, and the process is special) peerless good steel or can not be surpassed.

However, fortunately, I was also lucky in Tokyo at the beginning, and I actually let myself touch two thousand catties of pure Uzi steel at once, which is impossible to use to equip the whole army, but it is not a problem for all senior officers to have one Uzi steel sword.

Seeing that Lin Chong was silent, everyone thought that he was a little unhappy, and they all said: "Military master, this knife is very good, whether it is cutting the Song army, Liao dog, or Jurchen Tartar, it is like chopping melons and vegetables." ”

"yes, such a good knife, I really want to find someone to cut it now!"

"My broadsword is already hungry...... "Something strange seems to have come in."

Lin Chong smiled, turned his head to Ye Meng and Li Ming and said, "No, I'm thinking, you have to fix the high-carbon steel production process and carbon ratio first, and form a standardization."

A batch of cavalry knives and infantry knives were then produced, which were given to the soldiers and officers below for trial, and then modified and improved according to their opinions.

For example, I'll suggest now, it's better to add one of these gauntlets to the Cavalry Knife...... Infantry knives may be considered heavier and longer.

When the opinions are almost collected, after sorting out and testing a few more times, it can be mass-produced.

You work harder, this time you have made meritorious research and development, everyone including the apprentice will be rewarded with two months of silver, and Master Ye will make a list of meritorious personnel, I will give you a special reward! ”

Ye Meng, Li Ming and other craftsmen were very happy when they heard it, in the ordnance supervisor of the Great Song Dynasty, how could they have been treated like this, they were all excited and forgetful for a while, and the hard work of the past few days disappeared at once, and they only felt that they were full of energy.

Lu Jiang also smiled and said, "Brother, this knife doesn't have a name yet, why don't you choose a name?" ”

Lin Chong thought for a while and said, "Since my Liangshan Army is determined to block in front of Hu Lu, this knife is called the Broken Sword." ”

After a pause, he said again: "After mass production, remember to send two to which Zhang Shiro." ”
