Chapter 440 Come on, watch the birth of my great smelting technique (second update)

Chapter 439

But it has never been heard that molten steel can be smelted directly with this kind of mold.

"Your Highness, don't you understand? A lot of knowledge is involved here. Why is there a distinction between pig iron and wrought iron? It is because pig iron has a very high carbon content, and during the frying process, the carbon in pig iron The portion will be oxidized by the air, well...it means consumed."

While Wang Yang was talking, the craftsmen around him who were watching the Master Zhuangyuan all raised their ears, wanting to hear what the omniscient Master Zhuangyuan was saying.

The two green-robed officials who were sent by the emperor silently kept it in mind, thinking that with the virtue of the champion, he would not talk nonsense.

"The old man wants to ask Mr. Zhuangyuan, how did this steel come from? Could it have something to do with carbon?" It was the old craftsman, Old Liu, who asked this question.

Wang Yang nodded. "Old Liu, you must also know that when you fry iron, if you fry it, you will only get wrought iron, right? But if you haven't fried it, it can still maintain a certain amount of carbon. If you go down, you can get steel.”

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

"Hey, do you understand the number one scholar?" Old blacksmith Chen looked at Wang Yang in front of him with a surprised expression and exclaimed.And these words just confirmed that Wang Yangzhi was right.

"Moreover, Mr. 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, a sword that cuts iron like mud is a steel with high carbon content. It is made of steel with low carbon content, which is the kind of soft steel that is very elastic..."

"If you don't believe me, you can actually do an experiment. Isn't there some mild steel that is not very useful? Old Liu, you can go get some and fry it with the method of frying steel. Soon you will find that, Mild steel will slowly turn into mature iron..."

"Master, I'll go, let's try it out." After hearing Wang Yang's words, several young craftsmen immediately jumped up and ran over happily, wanting to see if they would really follow the champion. Prophecy in general.

After the old Liu shouted a few words hypocritically, he didn't stop him anymore. He really wanted to see if it was really what Wang Yang said. He will never have any more problems.

After all, every old expert who has been in this industry for so many years, seeing this young No. [-] Scholar so arrogant, is still secretly a little upset in his heart, and always feels that he should be better than himself and others in some aspects. .

Now, this clamp pot steelmaking method and the soft steel that Wang Yang said would be fried into mature iron are the last chance.

Fortunately, coking coal is used now, the heat is sufficient, and a few young men are working hard together, but Zhu Xiang's effort, a young and strong craftsman with an unbelievable surprise on his face, carried the piece of wrought iron came before the people.

"Master, Mr. Zhuangyuan, this, this soft steel has really been fired into iron..."

"Master Zhuangyuan, I don't even know how to praise you. Your ability to predict the unknown is much better than that of us old men who have been in this industry for decades..." Now, Old Liu Tou and a dozen old craftsmen were all convinced.

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

After Wang Yang picked up a piece of pig iron, he first asked someone to weigh it on a scale, and after some calculations, he directly put in three times the amount of iron ore powder. The element content can reach at least about 70.00%.

That is equivalent to [-] times that of pig iron. After the carbon elements in the pig iron are evenly distributed, plus the losses on the way, Wang Yang estimates that he should be able to produce the high-carbon steel he had in mind.

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

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

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

This guy rushed over and handed Wang Yang a pair of thick cotton gloves, and then handed him a long wrought iron pole with a downward curve in the front.

After Wang Yang picked up the long pole and stretched it out of the stove, he first removed the lid of the tong pot, and then stuck the tip of the hook into the pile of pig iron and iron powder. It seemed that there was a lot of resistance. Not completely melted, but that's ok.

Continue to wait, and everyone is staring at 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 as hard as a dry rice grain , but seemed to be stirring a bowl of slightly thick porridge.

"It's melted!" Zhao Ji beside him couldn't help shouting excitedly, but his eyes never left the graphite tong pot in the smelting furnace.

"Qilang, spoon..." Wang Yang greeted behind him, and Wu Qilang took the long hook in Wang Yang's hand, and then handed over a very long thing that looked like a cooking spatula in front.

After carefully reaching inside, Wang Yang gently scooped up the impurities floating on top.After yelling to step aside, the craftsmen who were standing behind his buttocks immediately stepped aside in unison.

After all, the molten iron that Wang Yang scooped out was no joke, but the half ladle of molten iron that was full of floating ballast was poured directly into one of the prepared yellow clay molds by Wang Yang.

After taking another spoonful, Wang Yang began to yell at Wu Qilang to help.Each of them took a larger wrought iron spoon, scooped up a spoonful of molten iron, and poured it behind the prepared rectangular clay molds.

When it was almost bottoming out, I changed two long forks, forked out the tong pot, and poured all the last molten iron into the mold.

After 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 gasped.

It turned out that the cloth on the surface of the glove was already faintly scorched, and Wang Yang couldn't help but secretly smashed his tongue. "No wonder my hands feel hot. It seems that I must prepare thicker gloves next time."

And everyone, including the two ordnance supervision officials appointed by the emperor, all gathered in front of the solidifying molds, waiting silently for the metal ingots to solidify. Dozens of pairs of eyes widened, as if those It's not just molten iron, it's like gold.
