"The charcoal kiln is built on the outside of the workshop to facilitate ventilation. ”

"The furnace is located in the middle of the workshop, so the smelting and disposal of the materials is easier. ”

"The blank drawing machine is also thrown in the corner, and there are enough pottery nowadays to be used at any time when needed. ”

The workshop area was still empty, and Xu Le continued to place the anvil on the front of the ventilation furnace, directly facing the ventilation hole.

In this way, he can reden the iron directly in the ventilation hole, and then transfer it directly to the anvil for forging.

"Iron tools will be the capital that I will live on on the island for a long time. ”

"Forged iron is much stronger than directly cast. ”

"Well, so the core of the workshop is built around ironsmithing. ”

Next to the anvil, a water tank about one meter long and more than 30 centimeters deep was built out of stones.

The ventilated furnace, anvil, and sink are all three things, and the positions are arranged in a triangle.

In this way, from heating to forging to quenching, it can be done in every square inch, and there is almost no need to move too much under the soles of the feet.

"It just so happens that the fire is also up, anyway, they haven't come back yet, build some more tools, and try the newly completed workshop!"

Iron slag is poured into clay pots and smelted in the fire!

The molten iron is poured into two long iron drills in the mold.

The iron drill is close to the middle and upper section, and two opposite hole grooves are opened, and the hole groove is passed through with an iron bar, and the two ends of the iron bar are smashed flat with an iron hammer.

The iron tongs are finished!

At the grip of the iron tongs, two pieces of jackal skin were also cut out to wrap it to isolate the temperature.

Then, using the same process, a boxy iron ingot was poured.

At the same time, a clay pot of iron slag was re-prepared and put into a ventilation furnace for smelting.

The iron ingots are clamped with iron tongs, sent through the ventilation holes into the ventilation furnace to be heated, and after being burned to a red color, they are transferred to the anvil and the hammer is picked up.

Ding, Ding, Ding!

The distance is closer, the time difference between heating and forging is shortened, and the shaping process is more intense.

Xu Le felt the feeling of the hammer hammering back, and at the same time kept flipping it with the iron tongs, so that every side of the iron ingot was evenly beaten.

With the constant sound of hammering, the iron ingot was gradually stretched and hammered thin.

Barrage in the live broadcast room——

"Look at it like this, is Big Brother Xu Le going to hammer out a knife blank directly?"

"The straight long knife, the Yang system, the Li system, the hand knife, or the embroidered spring of later generations?"

"It's the same infrastructure, but it's packed in one workshop, and it suddenly feels a lot more professional. ”

"Huh, why did Boss Xu Le bend the knife blank?"

In the sound of clanging iron, Xu Le hammered the iron material that had begun to take on a knife shape and folded it in half from the middle position.

Hit it a little further, and the two sections folded in half fit tightly!

Barrage –

"Stacked fights, big guy Xu Le, is this going to make the rhythm of a hundred stacks of steel?"

A stack of ...... Permian ......

The billet is constantly thinned and lengthened, and then folded repeatedly!

After ten stacks, the newly completed molten iron has been smelted.

The molten iron is poured directly on the stacked iron billet, wait until it solidifies slightly, and continue to repeat the stacking process just now.

Barrage –

"Burn pig iron essence to reweight the soft collar...... Boss Xu Le, this also uses the technology of steel filling?"

"Filling steel, in fact, is the process of pig iron decarburization and wrought iron carburizing, and the performance of the obtained steel is superior to that of ordinary iron!"

"Yes, I thought it would be a simple hammer and a stack, and you would be able to have a very high-quality iron blank. I didn't expect that Xu Le was not satisfied with this at all!"

Next, it depends on how far Xu Le can control the proportion of carbon. To be honest, there are no modern industrial instruments, and the success rate is very low due to human control!"

"This kind of artificial control can only be mastered by an old blacksmith of many years. ”

"It's not that I look down on Xu Le, he's too young. Age is here, and experience is bound to be limited. Still grabbed a handful of sweat for him. ”

In the discussion of the barrage, Xu Le completed the last stacking process.

Quench!

Woola!

Water vapor rises violently!

When Xu Le took out the iron knife blank again, the entire blade was cold and shining, although it had not yet been polished, but it had begun to show its edge.

Immediately afterwards, he re-inserted the iron knife blank into the ventilation furnace.

Barrage in the live broadcast room——

"It's ...... The tempering process is used again!"

"In the same way, it is very difficult to control the temperature by relying only on manual judgment! The temperature is not suitable, and the internal stress during quenching cannot be eliminated, which is equivalent to dry in vain!"

"Eh, why did Big Guy Xu Le leave? Ignore the iron knife blank? Just burn like this?"

"Uh...... Could it be that the steel filling just now got off, instead of overturning, it is better to return to the furnace and rebuild. ”

"It's not like ...... What are you doing when you come back with a big lump of lard?"

"Could it be...... It is oil quenching, which uses different cooling degrees of water and oil to greatly improve the performance of the material!"

I saw Xu Le pour the lard directly into the sink.

Next to the high-temperature heat radiation of the ventilated furnace, the grease quickly melted, covering the surface of the water with a thick layer.

At this time, Xu Le violently pulled the iron knife blank out of the ventilation hole-

Press into the sink!
