Time passed slowly, Chu blacksmith, Jiao Yong, Chu He and others took turns to fight, heated for more than ten hours in a row, the iron finally melted into molten iron, Chu He stirred the molten iron several times, increased oxygen to reduce the impurities, and when the impurities almost precipitated, the molten iron also turned into molten steel.

Seeing the situation of the molten steel, Chu He finally breathed a sigh of relief, although the molten steel did not meet his expectations, but compared with the high-carbon steel refined by the stewed steel method, it had been improved a lot.

When the valve is opened, the red molten steel flows down the refractory tank.

Chu blacksmiths and others have no experience in this area, but Chu He is different, and he is even more sure that this steel has been refined, and he has never failed to live up to his more than three years of study.

Waiting for the molten steel to cool, Chu Blacksmith and the others took a deep breath, their eyes full of shock.

In the past, the master of the demon army could make 100 steels, but the master craftsmen all day long, it was already very good to make 100 catties of steel.

Now, Chu He just built a strange furnace, took them upside down for a while, and then sold some hard work, and then, steel simply popped up?

Jiao Yong's eyes suddenly turned red, and Gu Gao said in a hoarse voice: "What if...... If only I could have ...... before."

The blacksmith Chu raised his hand slightly, stopped Gu Gao, and then said, "Chu He, these are the alloy steels you said?"

Chu He shook his head: "Not yet." The conditions are simple, and only by using a stupid method can we purify and refine the iron first, then refine pure manganese, and finally melt the steel again, add ferromanganese and ferrosilicon, and then make alloy steel. ”

"I don't know if I'll make it. If it succeeds, one furnace of alloy steel will be enough for us for a while. It is mainly used to craft bows and arrows. ”

"When it's successful, I'll tell you the exact proportions. Don't spread these things, as long as they don't leak out, even if the blast furnace is taken away, nothing can be refined. ”

Don't look at the simplicity of small blast furnace steelmaking, but this is the experience and knowledge accumulated in the past two thousand years, the firing of key refractory bricks, the selection of coke, the addition of reducing agents and oxidants, etc., are not just a few glances that people here can copy at a few glances.

The composition ratio of silicon-manganese alloy steel is different, the performance changes greatly, and the quenching and tempering of the created armor are different, which can greatly affect the quality of the finished product.

Even if the Chu blacksmith and others saw with their own eyes how Chu River made steel, they didn't understand the principle at all, and could only make steel rigidly according to Chu He's method.

If they were to build a small blast furnace from scratch to make steel, Chu blacksmiths and others would not be able to do it.

In the end, Chu He left a hand, just the refractory bricks, and the Chu blacksmiths didn't know how to fire them.

Although the stupid method of smelting multiple times is time-consuming and labor-intensive, it also has an advantage, that is, the quality of the smelted steel will get better and better, which is similar to the multi-time hammering of 100 refined steel.

Of course, this method is definitely not worth the loss on the earth, and the little steel that is smelted is probably not worth it manually.

In today's world where steel is scarce and incredibly valuable, this amount of manpower and material resources is negligible.

If it weren't for Chu He's worry that the iron materials he purchased would not be able to meet his needs, and the iron materials were pipe products and difficult to buy in large quantities, he wouldn't even have to let people look for iron ore everywhere.

Compared with steel weapons worth tens of thousands, the cost of iron is completely negligible.

In order to refine silicon-manganese alloy steel, Chu He has even fallen behind in the cultivation of the golden bell jar these days.

Of course, the main reason is that the tiger bee was broken by the Chu River, and the 100,000 tiger bees attacked the Chu River twice, almost all of which ran out of poisonous needles, and it took some time to recover.

Chu He estimated that after a few days for the tiger bee's poisonous needle to recover, and if he took turns to attack again, the golden bell jar could be practiced

In less than two months, he was able to cultivate a double golden bell jar, and the speed had already surprised Chu He, and he really couldn't bear to squeeze the poor and cute tiger bee again.

If you want to continue to develop and get a steady stream of demon honey, you must let the tiger bee retain some poisonous bees with attack power, otherwise it will be a problem for the tiger bee to go out to collect honey and protect the hive.

These days, of course, are studying the refining of silicon-manganese alloy steel.

The hard work paid off, and two furnaces of alloy were continuously refined, and after two improvements, it really tossed a furnace of barely qualified silicon-manganese alloy steel for Chu He.

The performance of this alloy steel cannot be compared with the silicon-manganese alloy steel refined by the earth, and the impurities are relatively high, but the performance has far exceeded the high-carbon steel produced by the stewed steel method, and the ductility and toughness have reached the goal of Chuhe.

If you change the proportion of silicon-manganese and enhance the hardness of alloy steel, you can completely create alloy steel weapons with hardness exceeding 30% of high-carbon steel weapons.

At this time, Chu Blacksmith and the others were already completely convinced of Chu He, and immediately buried themselves in hard work and began to build a super strong bow for Huang Zhong.

Next, in fact, there is nothing to do with Chu He.

He is not good at crafting weapons, as long as he teaches the things of quenching and high-temperature tempering to Chu blacksmiths and others, he will naturally be able to get alloy weapons with higher performance.

Originally, Chu He didn't have much interest in the battle armor, after all, he was still young, and his height was growing, even if he deliberately made the battle armor a little bigger, he wouldn't be able to wear it for a year or two at most.

However, after experiencing the tiger disaster, he also understood that even if he had the golden bell shield to protect himself, no matter how much armor he had, there was no harm in it.

Anyway, you can now use a small blast furnace to make steel, and the loss of materials to build a warframe is nothing.

Just as Chu He pondered that the tiger bee should have recovered a lot of poisonous needles, and was about to enter Huya Ridge again and give the golden bell jar a final sprint, who knew that Jiang Wei suddenly sent someone to report that the one-horned white tiger suddenly appeared in Qinghe Village.

But it's very strange that the one-horned white tiger didn't hurt anyone, but just broke into Qinghe Village, and then kept wandering around the Chu River mansion and roaring, and it didn't hurt anyone.

Jiang Wei already knew that the white tiger had spirituality, and when he saw the white tiger's abnormal performance, he guessed that the white tiger should have come to find Chu He, but there was no malicious intent.

But just in case, Chu He's parents left the mansion, and the Wu Shizhu family next to him also moved to other places, Jiang Wei took a group of young and strong people, like a great enemy, surrounded the white tiger.

Chu He heard the report from Qingzhuang, and he also had a sigh in his heart, I don't know why this white tiger, who had disappeared for more than half a month, suddenly came to Qinghe Village to find himself.

Originally, if Chu He could practice the double golden bell jar, and then meet the white tiger, it would be the safest.

If the White Tiger appeared in Shishan Village, Chu He would definitely ignore the threat of the White Tiger and attack the Golden Bell Jar realm first, but when the White Tiger appeared in Qinghe Village, the situation would be completely different.

Chu He didn't dare to bet on the patience of the white tiger, in case this evil beast didn't see his whereabouts for a long time and became angry, the young people of Qinghe Village, including Jiang Wei, would not be able to resist the fierce power of the white tiger.

There was no way, he had to quickly return to Qinghe Village to see what the white tiger was doing.

If it really doesn't keep its promise and intends to attack and kill the villagers, don't blame yourself for being polite, you will definitely try to lure the white tiger to Huya Ridge, ask Huang Zhong to take action, and kill this evil animal.
