Since the deliberations in the Juyi Hall that day, Liangshan Cottage has been extremely busy, but fortunately, a group of heroes perform their duties and everything is in order. Pen & Fun & Pavilion www.biquge.info

On this day, Li Zhu, Zhu Wu and others followed Wang Lun to the Ordnance Prison, where iron was being struck, and the clanging sound was non-stop. Next to an anvil in the middle, a strong man with a pockmarked face was very conspicuous, although his figure was not very tall, but his muscles were bulging, his skin was dark, and he was covered with some burns.

I saw that the big man was carrying a bear on his back, and on such a cold day in October, he was naked, wearing only a pair of bull-nosed shorts, and his muscles were protruding. It shimmered in the firelight, sweating and steaming. He was holding a surprisingly large hammer and striking it with one stroke, and his gestures were extremely skillful. Wang Lun and the others came in, the big man was concentrating on striking iron, and the sparks splashed on his body, as if he didn't realize it.

The Liangshan Weapons Supervisor is an independent courtyard with a river passing by it, and the location is excellent. In addition to six or seven blacksmiths in this courtyard, there were more than twenty men who worked on it.

Tang Long, who was striking iron, suddenly stopped and shouted: "The fire is not good, you wait for the afterburner to fan the fire, if so, how long will it last?" “

As he spoke, he threw down the hammer and kicked a guy with a leather bellow, and scolded angrily: "It's useless, you can't even fan the wind." ”

Li Zhu couldn't stand watching from the sidelines, so he stepped forward and shouted: "Brother is here, Brother Tanglong must not be rude!" ”

When Tang Long saw Wang Lun this time, his face changed, and he saluted: "Tang Long has seen my brother!" The younger brother is in a hurry, don't blame the elder brother! ”

Wang Lun flicked his hand and said, "Brother Tanglong has a good temperament, don't worry about it!" As soon as the conversation changed, I heard Wang Lun say again: "Brother Tang Long, what difficulties have you encountered?" ”

Lowering his head, Tang Long sighed and said, "The younger brother also fights more than a dozen good weapons every day, but it's a pity that the guys here can't do it, they don't even know how to blow the wind, and they can't get the heat, so it's always worse." ”

Wang Lun was also very curious about the iron-making technology of the Song Dynasty, so he said to Tang Long: "I also have some research on iron-making technology, so why don't I see if I can help Brother Tang." ”

Tang Long didn't want Wang Lun to know how to make iron, so he was quite surprised, so he immediately said, "In this case, I have to ask my brother for advice." ”

When everyone came to the iron furnace, they saw a blast furnace, only revealing a furnace less than a foot long, the flames were beating, burning a section of iron embryo in the furnace red, and a man tried to use a cowhide wind to blast the wind.

Wang Lun admired it very much, the iron-making technology of the Song Dynasty was already very sophisticated, and there was no difference between this small blast furnace and modern earth-based steelmaking.

At this time, another guy added some coal to the stove, and Wang Lun asked directly: "Have you started using these fuels?" “

Tang Long replied, "This is charcoal, which burns more vigorously than charcoal, and is the best fuel." It's just that Liangshan didn't have this thing, and he had to purchase it from thousands of miles away, and he didn't need it. ”

Wang Lun vaguely remembered that the literature said that the Northern Song Dynasty began to use a large amount of coal as fuel, so he sincerely praised: "I have long heard that millions of households in Kaifeng rely on coal, and there is no one who burns wages, which can be seen today." ”

Walking around the weapons prison, Wang Lun suddenly remembered that some people used coke in the Southern Song Dynasty, which should increase the firepower, so he said: "I have a way, put these charcoal in the furnace, seal the fire and burn it, and then you can get a hard stone, called coke." It has no smell when burned, and its appearance is similar to charcoal. However, the firepower is superior to that of charcoal, and the quality of the iron smelted is of high quality, so the Tang Long brothers may be able to give it a try. ”

Tang Long listened to Wang Lun's words, thought for a moment and then had an eyebrow, and said happily: "I didn't expect my brother to have such a wonderful method, and I have also heard of Jiaozhi's words, but I can't understand it." Today's elder brother's words made the younger brother pause. ”

Wang Lun nodded, saw the cowhide wind row, and had another idea, and said: "In this way, this wind row should also be improved." Make two slender wooden boxes, one is just set on the outside of the other, make an air hole outside, install the handle, and twitch the wooden box inside, you can blow the air, which is called a piston wooden bellows, and the wind is stronger than the cowhide air row. ”

In order to enhance the iron-making capacity and improve the quality of iron-making, the earliest blast iron-making technology was invented during the Warring States period. This kind of blast iron smelting uses a leather bellows pressed by manpower. In the Western Han Dynasty, horse steaks and steaks (that is, leather bellows driven by horses and oxen were used to blow the wind). Especially in the early years of the Eastern Han Dynasty, the hydraulic blower bag was invented-water drain.

These blast iron-making technologies are miracles in the history of world smelting. It was not until the end of the 13th century, after 1200, that blast ironmaking technology was introduced to Europe. It was only in the 14th century that the first furnace of pig iron was smelted in Europe. The piston wooden bellows proposed by Wang Lun was invented in the Ming Dynasty, which increased the wind pressure and air volume, strengthened and optimized the smelting, and increased the output to a certain extent.

Tang Long is an expert in iron, and when he heard it, he suddenly realized, "This idea is really high!" Brother, please bow to the younger brother! ”

At this time, the craftsmanship of craftsmen was passed down from father to son, and it was never taught lightly. Even if you are a master, you are afraid that the apprentices of the church will starve to death of the master, so you will keep the bottom of the box. Wang Lun taught Tang Long two secret methods in a moment, and Tang Long was grateful. What could be more precious to a blacksmith.

Tang Long couldn't bear it at the moment, so he asked Wang Lun to draw a figure and asked two guys who knew how to carpenter to make it according to the pattern. In a moment, the bellows have been ready, the guy has good craftsmanship, and the bellows made are perfectly fit, and there is no air leakage.

The guy who blew the wind took the bellows and tried them out in front of the stove, and everyone gathered around to see the effect of the new bellows. Sure enough, with only one guy pulling the bellows, and without pulling twice, the fire rushed up, the flame was several feet high, and the flame gradually turned white.

Tang Long applauded: "Okay, I haven't seen such a good firehead." He hurriedly put a knife that had been half beaten into the fire and forged it, stared at the fire, and shouted: "Blow the wind harder." ”

Another guy also stepped forward to help pull the bellows, and after a while, he saw that the fire was getting whiter and whiter, and Tang Long shouted, "The fire is perfect!" He violently took out the short knife with fire tongs and threw it into a bucket of water to quench it, only to hear the continuous sound of sizzling and the smell of water.

Tang Long held the knife and saw that there were faint patterns floating on the knife body, releasing bursts of cold air, and said happily: "It's done!" Although the steel of this short knife is not the best, the heat is excellent, and it is worth hundreds of steel-making knives after opening. ”

Everyone was happy and came to see the new knife. Li Zhu and Zhu Wu's understanding of Wang Lun has deepened again, and Brother Xindao is really erudite and deeply hidden.

Tang Long saw that he had a new-style bellows, and he felt like a tiger with wings, and he was in a good mood, and said: "The elder brother is really strong, and the younger brother has benefited a lot." ”

Wang Lun was flattered by Tang Long, and he felt comfortable and had the heart to show off. said: "For weapons, I have another idea here! ”

There are clever guys, who have already brought up the paper and pen and ink, and Wang Lun immediately drew a figure of a modern saber.

Wang Lun pointed to this saber and introduced it to everyone, "This knife has a blade length of nine inches and three minutes, a blade length of five inches and six minutes, and the widest part of the knife is one inch and one minute, and two points thick. The handle of the knife is perforated, and the rope is wound as the handle of the knife, which is integrated and very suitable. ”

Tang Long saw such a military weapon for the first time, and asked curiously, "Why is it like this?" ”

Wang Lun pointed to the sketches of the saber and introduced them one by one: "This knife has a rough square head and a wide back, thick and sturdy. The serrations on the back can cut the thick wood of the bowl, and can be chopped, stabbed, chopped, slashed, and cut. In addition, it can also be used as a crowbar, a shovel, a hammer, and a throwing knife. The knife is sharp, and it is a sharp weapon for killing, and even iron armor can pierce it. ”

Li Zhu listened to a few points and said: "This knife is multi-purpose, it is indeed convenient, and Brother Shiqian must like it very much!" ”

Tang Long also said: "This knife is really a good knife!" It's like my cousin Xu Ning's hook and sickle, which can be a gun and a knife, unpredictable. ”

Zhu Wu, the Divine Machine Military Master, suggested on the side: "This knife is sharp, I'm afraid it is not easy to build, for the time being, it may be possible for all the leaders and the brothers of the outpost camp to have a hand!" ”

Wang Lun looked at Tang Long and said with a smile: "Then it depends on Brother Tang's methods." ”

When Tang Long heard this, he laughed and said confidently: "To make a good knife, annealing, normalizing, quenching, and tempering are indispensable!" The famous teacher Qi Wuhuaiwen of the previous dynasty once left the secret method, and my ancestors also passed on this method, and there is a mantra that says that bathing is drowned in five animals, and quenching is quenched with the fat of five animals!"

Qi is not a surname, Huaiwen is a name, and his person is a famous metallurgist in the Northern and Southern Dynasties of China. His greatest contribution was the creation of a new method of steelmaking, which later became known as the "steel filling method" or "group steel method". "Burn pig iron fine, heavy and soft collar, and several nights will become steel."

Qi Wuhuaiwen is not only a famous metallurgist, but also an excellent knife expert, the experience of the previous artificial knife has been studied, compared, and through continuous practice, a new set of knife making technology and heat treatment technology has been created.

Qi Wuhuaiwen's method of making knives is: first smelt pig iron and wrought iron into steel by filling steel method, make a cutting edge, and then "take soft iron as the spine of the knife, bathe in the drowning of the five animals, and quench the fat of the five animals", and the knife that comes out of this way is called the "Su Iron Knife", which is extremely sharp and can cut off the iron armor thirty times at once.

Wang Lun also knew that Qi Wuhuaiwen didn't want Tang Long to be a disciple of a famous family, so he was overjoyed and said: "With Brother Tang Long in charge of the weapons superintendent, my Liangshan is like a tiger with wings!" ”
