Chapter 439

However, I have never heard of this kind of mold that can be used to directly smelt molten steel.

"Your Highness, you don't know, do you? There is a lot of knowledge involved here, why there is a distinction between pig iron and wrought iron, it is because the carbon content of pig iron is extremely high, and during the frying process, the carbon in the pig iron will be oxidized by the air, so ...... It means to be consumed. ”

While Wang Yang was talking, the craftsmen who were watching the champion around him were stunned, and they all wanted to hear what this omniscient and omniscient champion was saying.

And the two green-robed officials who were sent by the Son of Heaven silently kept it in their hearts, thinking that with the virtue of this champion duke, they should not talk nonsense.

"The old man wants to ask the champion father, how did this steel come from? Could it be that it has something to do with carbon? The one who asked this sentence was the old craftsman Lao Liutou.

Wang Yang nodded. "Old Liu Tou, you must also know that when you fry iron, if you have fried it, what you get will only be wrought iron, right? But if it has not been fried, and a certain amount of carbon can be maintained, steel can be obtained. ”

"Just like Lao Chen, when you usually smelt swords, do you still like to sprinkle some carbon foam on the edge of the knife, so that the sword will be sharper."

"Hey, you know that?" Old Blacksmith Chen looked at Wang Yang in front of him with a surprised look and exclaimed. And this just proves that Wang Yang's words are right.

Moreover, Wang told you that although steel is between pig iron and wrought iron, the quality of steel still has a lot to do with the amount of carbon. For example, the sword with iron like clay is made of steel with a high carbon content, and the steel with a low carbon content is the kind of soft steel that is full of elasticity......"

"If you don't believe me, you can actually do an experiment, isn't there some mild steel over there that is not very useful? Lao Liu, you can go and take some and fry them with the method of frying steel, and soon you will find that the soft steel will slowly become mature iron......"

"Master, I'll go, let's go and try it." After several young craftsmen heard Wang Yang's words, they jumped up directly and rushed over happily, wanting to see if it would really be the same as the prophecy of the champion prince.

After Lao Liu Tou hypocritically shouted a few words, he didn't stop it anymore, he actually really wanted to see if it was really as Wang Yang said, if it was really the same as what Zhuang Yuangong said, then he would definitely not have any more problems.

After all, every veteran connoisseur who has been engaged in this industry for so many years, seeing this young champion so coaxing, is still secretly a little unhappy in his heart, and always feels that he should be inferior to himself and others in some aspects.

And now, this tong-pot steelmaking method and the soft steel that Wang Yang said will be fried into mature iron is the last chance.

Fortunately, coking coal was used now, and the heat was sufficient, and a few young men worked together, but with the help of Zhu Xiang, a young and sturdy craftsman with a look of incredible surprise came to everyone with the wrought iron on his face.

"Master, Champion Gong, this, this soft steel has really been fried into mature iron......

"Champion Gong, little old man doesn't know how to praise you, your ability to be an unpredictable prophet is much better than those of us who have been in this industry for decades......" At this time, Lao Liu Tou and more than a dozen old craftsmen were convinced.

The small blast furnace had already begun to burn, and in front of Wang Yang was a graphite tong pot that was about equivalent to a wine jar that could hold about ten catties.

After Wang Yang picked up a piece of pig iron, he first asked people to weigh it on the scale, and then after calculating, he directly put in three times the iron ore powder, and now the iron content of this ground iron ore powder can reach at least about 70%.

That is equivalent to two and a half times that of pig iron, and after the carbon elements in pig iron are evenly shared, plus the loss on the way, Wang Yang estimates that he should be able to practice the high-carbon steel in his impression.

Soon, seeing that the bimetal thermometer at the mouth of the furnace had begun to deflect, Wang Yang sent the loaded tongs and pots into the blast furnace with tools made of wrought iron.

At this moment, the Great Smelting Technique finally began under Wang Yang's operation, and then, everyone began to stare blankly at the tongs pot surrounded by blazing white flames in the blast furnace, and gradually, the flames gradually turned blue.

Everyone stood outside the furnace mouth, and it was obvious that the pig iron and iron ore powder in the tongs pot, as well as the auxiliary materials, began to change color and gradually turned red, and Wu Qilang next to Wang Yangchong hooked his fingers.

This guy rushed over, handed Wang Yang a pair of thick cotton gloves, and then handed over a long wrought iron rod that bent down in front.

After Wang Yang picked up the long rod and stretched out the stove, he first removed the lid of the pot, and then pierced it into the pile of pig iron and iron powder with the tip of the hook, which seemed to have a lot of resistance, and it seemed that it had not completely melted, but it didn't matter.

continued to wait, and everyone watched Wang Yang's actions in a daze, but when Wang Yang stretched out the pole for the third time, he finally felt that his pole was no longer a hard lump like facing dry rice grains, but seemed to be stirring a bowl of slightly thick porridge.

"It's gone!" Zhao Ji next to him couldn't help but shout excitedly, his eyes never left the graphite tong pot in the smelting furnace.

"Qilang, spoon ......" Wang Yang beckoned behind him, Wu Qilang took the long hook in Wang Yang's hand, and then handed over a very long thing with something like a spatula for stir-frying in front.

Wang Yang carefully reached into it and gently scooped up the impurities floating on the top. After shouting out of the way, the craftsmen who were originally standing behind their butts all flashed to the side in unison.

After all, the molten iron scooped out by Wang Yang was not a joke, but this half spoonful of molten iron full of floating ballast was directly poured by Wang Yang into one of the yellow clay molds that had been prepared.

After scooping another spoonful, Wang Yang began to shout at Wu Qilang to come forward to help. Each of them held a larger wrought iron spoon and scooped spoonfuls of molten iron and poured them over the prepared rectangular clay molds.

When he was almost at the bottom, he changed two long forks, forked out the tongs, and poured all the last molten iron into the mold.

Putting down the mold that had been emptied of molten iron upside down, Wang Yang threw the iron fork in his hand aside and took off his gloves, at this time, Zhao Ji beside him couldn't help but gasp.

It turned out that on the cloth on the surface of the glove, the burnt yellow was already faintly visible, and Wang Yang couldn't help but secretly smack his tongue. "No wonder I feel hot on my hands, and it looks like I'll have to prepare thicker gloves next time."

And everyone, including the two ordnance prison officials appointed by the Son of Heaven, all gathered in front of the condensed molds, silently waiting for the metal ingots to solidify, and dozens of pairs of eyes were round, as if those were not ordinary molten iron, but gold.
