184 How is steel made?

The silver-white fine iron embryo quickly burned bright red in the fire. Although the ghost was not very energetic, Pei Jieluo's method of manipulating the fire element was simple and skilled, and he could still feel 70% or 80% when standing beside him.

"It's quite like I manipulate metal elements," Agui said silently in his heart, "It's just that he controls those active fire elements better. Fortunately, this stove is controlled by Master Pei Jieluo. If you use an apprentice, it will take half a day to reach this temperature!"

The refined iron embryo in the stove is getting hotter and hotter. Agui can feel that the metal elements on the iron embryo have been stimulated by the fire element. This is the old Albert, who has been watching the refined iron embryo like a skilled cook, pouring some gray-black powder from the gourd and carefully spread it on the iron anvil, and then quickly with iron pliers. The refined iron embryo, which had been slightly deformed, was put on it, and sprinkled a layer of secret medicine on the refined iron embryo with a shake of the wrist.

Then the old Albert folded the refined iron embryo several times like an ordinary stack, and threw it into the stove and waited for its temperature to rise again.

"It's really a master..." The ghost praised and recalled the old Albert's forging just now. His every hammer was so accurate that he maximized his power. Although the old Albert could not beat the refined iron embryo as soft as mud like the ghost, but he hammered the refined iron embryo like an obedient child. Zi, quickly and accurately completed the rolling and folding action.

Although old Albert is not a warrior, his years of iron experience made the sledgehammer as flexible as a spoon in his hand. From the touch of the hammer, the ghost seems to see a hammer master exerting a gorgeous set of martial arts. The whole movement is smooth, without hesitation, no pause, no pause With any drag, the refined iron embryo fell to the anvil and returned to the furnace, and the tremor of the metal elements there did not stop for a moment.

A ghost really didn't expect that the old blacksmith could achieve a tremor effect similar to elemental control with a hammer in his hand!

The mysterious powder is like a small rice cake. It rolls into the iron element and immediately formed a small ball with them. The ghost observed the change of the iron element with great interest. Under the action of the secret medicine, the original pure iron element gradually became turbid, and then they actually melted under the high temperature and forging. Together, a new metal element was formed. Although this new element is not as pure as iron, its structure has become closer, and the already small refined iron embryo has quietly shrunk by another 30%.

Unconsciously, the iron embryo in the stove changed from bright red to bright cherry red. Then the old Albert stopped forging and took it out of the stove and immediately threw it into the sink.

"B bring water!" The two old men shouted almost at the same time, and the bald Qiang immediately ran up and handed over the two kettles prepared in his hand. The steelmaking was not finished yet. Pei Jello by the stove poured a few mouthfuls of water and quickly wiped the sweat on his face, and then concentrated on manipulating the fire to increase the temperature in the furnace.

Old Albert waited for a while to pick up the slightly cooled embryo with iron pliers and put it into a new sink to continue to cool down. In this way, the embryo was soaked in three sinks. This was not over. The embryo that had just cooled was actually thrown into the stove by Old Albert, while Feijello gathered quickly. The fire element heated it up. It only took a cup of tea, and the embryo that had just lowered the temperature was burned to cherry red again.

Old Albert threw the hot embryo into the sink one by one and lowered its temperature as before. In everyone's doubtful eyes, Old Albert actually threw the cooled embryo into the stove again. Under the manipulation of Feijello, this unlucky embryo is now The sky burned cherry red for the third time.

The old Albert, who carefully observed its change, did not toss it any more, but continued to wait patiently. It was not until the embryo softened into iron water that he picked up the wooden basin without hesitation, poured all the dry powder inside and directly buried the iron embryo tightly, and then the apprentices ran up according to the master. Zi's order closed the upper and lower furnace doors, and the whole furnace was closed.

The two old men took a breath at the same time, and the old Albert had a chance to come over and explain the operation just now with Agui, the bald Qiang and the other two apprentices.

The previous forging is just to add the secret medicine. When the iron embryo and the secret medicine are evenly combined, it will turn cherry red at high temperature. At this time, it is necessary to quickly cool the embryo. The senior blacksmith calls it quenching. When the temperature drops, the result is already a steel block, but it is only hard but lacks toughness, resulting from The weapon is very fragile and easy to break. At this time, the hardened steel block should be heated again until it turns red and cooled down again. This is called tempering. At this time, the steel block will be slightly softer and tougher, but this is not the best effect of steel. It must be heated again, and it must be burned until it is about to melt away before sealing the embryo in the furnace with the dry powder in the wooden basin. In this case, this is called annealing, so that when the billet is completely cooled tomorrow morning, it will be an advanced material with the best toughness to hardness.

"Each senior blacksmith has its own unique understanding and technique. Some people will temper twice or even many times. This kind of steel is more resilient, but if it is too soft, it is only suitable for bows rather than the blade of swords. During this period, the time required for each process must be mastered by yourself, and every slight change will be created. Billets with different characteristics. After saying that, old Albert quickly went to the cloister and sat down, laughing with the gasping Fjero: "Ha ha, the old man is tired enough. It seems that we are all old, and I don't know if these kids can take over our class. I hope the hammer will get better and better..."

The two old people looked at the little boy around the stove and smiled slowly. Their era has slowly unfolded...
