The 100KW gas generator has been transferred to the power plant for unified deployment and use without Wei Minsheng figuring out its function.

Fortunately, when this workshop was built, it was arranged near the power plant, considering that some of the equipment inside may consume a lot of power resources.

The circuit was laid in accordance with the requirements of Liu Mengling's design plan for professionals, and a transformer was specially installed for this workshop.

A total of two such small intermediate frequency melting furnaces were purchased, both with a power of 35KW and a maximum design temperature of 1800 degrees Celsius, which is enough to melt ordinary steel materials.

The maximum melting mass per furnace can reach 30 kilograms, but for metals with high melting points such as steel, a maximum of 10 kilograms can be processed at a time.

This kind of processing power is more than enough for those ordinary tool manufacturing.

After Wei Minsheng informed the power plant through the walkie-talkie to ensure the power demand of the workshop alone, he connected the smelting furnace body and the water circuit in accordance with the requirements of the instructions for the use of the intermediate frequency furnace.

Close the main power switch of the workshop, adjust the power of the melting furnace to a minimum, and turn on the power switch of the melting furnace.

Then he took a few pieces of leftover material from the cutting of round steel plates and put them into the crucible of the melting furnace with iron tongs.

Since this was a trial run, and the purpose was only to make a knife, only more than a pound of leftovers were put in.

As the power increased, a faint green smoke rose from the surface of the material inside the crucible.

Wei Minsheng looked at the manual while operating the smelting furnace, although the action was a little rusty, but it only took a few minutes to turn the leftovers in the crucible into molten iron.

Zheng Yuan next to him was dumbfounded, what is the situation?

Why didn't I see any flames, those hard materials turned into a puddle of molten iron under my nose.

Wei Minsheng shook the handle and controlled the crucible to pour the molten iron inside into the finished mold, and after cooling, a cylinder was formed.

Seeing the cylinder that had been formed and still had high temperatures, Zheng Yuan, who was in a daze, seemed to come to life in an instant, and instinctively entered the state when he was striking iron before.

With his left hand, he grabbed the tongs next to him, clamped the cylinder to the anvil, and with his right hand, grabbed the hammer next to him and swung it.

With the sound of "bells, bells", the cylinder seemed to come to life, constantly changing shape under the hammer.

However, the temperature of the material had dropped a lot by the time it was taken out of the mold, so after a dozen hammers had to be lowered, it needed to be heated again before it could continue to be forged.

Zheng Yuan picked up the iron block and was about to draw a gourd according to Wei Minsheng's appearance and put it in the crucible to heat it, when Wei Minsheng stopped him with a voice.

The function of this crucible is to melt the irregular scrap into molten iron, and then cast it into regular steel ingots, which is convenient for later processing.

Ordinary heat treatment does not use such a large power, only a special coil can be used to heat the workpiece very conveniently, and the heating time is shorter, and the efficiency is higher.

Wei Minsheng opened another intermediate frequency furnace and connected it to the special coil.

Use the tongs to suspend the beaten iron in the middle of the coil, and as the power increases, the iron turns red at a speed visible to the naked eye.

I hadn't seen what was going on when I had melted the scrap in the crucible, but now the piece of iron was under my eyelids, and in a few breaths it was burned red by the "colorless and invisible flame".

What kind of flame is this?

Except for the heat emitted by the red-hot iron on the tongs, the temperature of the other flames was not felt.

Holding back the surprise in his heart, Zheng Yuan took the piece of iron handed over by Wei Minsheng and put it on the anvil again and beat it.

With such a convenient and fast heating equipment, it didn't take long for a machete to be built by Zheng Yuan.

Now, it's time to get to the crucial step, just after quenching, you can test whether the machete can cut the wire.

Taking a deep breath, Zheng Yuan used an iron bucket to fetch a bucket of water from a puddle on the surface of the ground on the top of a hill.

Quenching is the key to turning ordinary weapons into "mortal soldiers" or "divine soldiers", according to Zheng Yuan's ancestors, it is necessary to take the closest "heavenly water" to the sky, plus a unique formula, you can greatly improve the probability of becoming a "divine soldier".

Wei Minsheng saw Zheng Yuan's approach, and felt in his heart that this "heavenly water" was probably not because it was closest to the sky, but because the water in the puddle on the top of the mountain was the purest rainwater, and it would not contain other minerals and trace elements that could not be mastered like well water.

This kind of water can ensure the similarity of the quenching fluid, so as to ensure that there will be no uncontrollable results caused by different water quality after being added to the formula.

Zheng Yuan also knelt on the ground reverently and bowed to the sky a few times when he was fetching water, and he still recited words in his mouth, probably to ask for God's blessing.

After getting the water, Zheng Yuan took out a small bag from his personal place, carefully poured some of the contents of the small bag into the bucket, stirred it well with a wooden stick, dipped it with his hands, closed his eyes and tasted it with his tongue.

After a few moments, he poured some more from the pouch into the bucket and continued to repeat the previous action.
