Start a blacksmith shop

Chapter 4 Experiment
Li Zhenhua's heart skipped a beat when he saw the reminder in front of him.

This is really good, with this analytical eye, it will be much more convenient for him to choose coal that can be used for blacksmithing.

In just a short while, Li Zhenhua picked out a dustpan of iron and carbon from a pile of coal.

This is the best carbon that has been selected for its high firepower and long burning time.

After selecting the coal, Li Zhenhua came to the side of the stove with a dustpan of coal, and removed the refractory brick sealed on the stove mouth.

Take the blower out of the air outlet again, turn on the power and try it out to see if there is any problem.

When encountering the blower in the middle, the analytical eye has already given the conclusion that the blower is good, but Li Zhenhua still tried it with his hands.

Reinstall the blower, and take out a few pieces of iron carbon in the dustpan, just enough to cover the air outlet.

Li Zhenhua took a newspaper and lit it and threw it into a small stove converted from a milk powder bucket, and then added a small pile of broken wood into it, and the newspaper ignited the wood.

Li Zhenhua threw two pieces of charcoal into the small stove, and after a while, the charcoal thrown in caught fire.

Holding iron chopsticks, Li Zhenhua took out the ignited carbon and put it in the big furnace.

Pull the unburned carbon grill around, and then turn on the switch of the blower.

The fire in the blacksmith furnace blows in a large amount of air with the blower, and all the carbon is ignited.

Looking at the stove that was ignited once, Li Zhenhua once again remembered the days when he and his grandfather were blacksmithing together, and he was also in charge of lighting the stove at that time.

Li Zhenhua stopped the blower and walked towards a room not far from the stove in the yard.

After a while, when Li Zhenhua came out again, he was holding a bow plate in his hand, which is also what people often call spring steel.

This thing is now on the Internet, and it is often made into knives in the hands of some craftsmen. Of course, most of them are made into kitchen knives.

Li Zhenhua also used this spring steel to strike a knife today. This decision was quite difficult.

Because when his grandfather was around, he often warned him that knives are also weapons, so be careful when hitting.

After thinking about how to deal with it after playing, it will be a big deal if it is lost in the shop.

Li Zhenhua understood what grandpa meant, it meant to keep him in awe of weapons.

But which boy doesn't love weapons?Isn't there a saying that says that a man is a teenager until he dies, even an old man in his seventies and eighties has a heart that loves to play.

So today Li Zhenhua made an exception. The big deal is to hide the knife after finishing the work, so that no one will know and it will be over.

Besides, what Li Zhenhua intends to make this time is not a long knife, but a short knife. As for the style, he chose the simplest watermelon knife, which is also the most commonly used thing by young and Dangerous people.

The bow board that Li Zhenhua chose today is only [-] centimeters long, but it is [-] centimeters wide.

So the first thing to do now is to burn the iron red, and then make a knife shape into a knife blank.

When Li Zhenhua was doing these tasks, subtitle prompts often appeared in front of his eyes, displaying various data.

The iron was put into the stove, Li Zhenhua turned on the blower, and the subtitles appeared again.

It showed that the temperature inside the furnace rose from one or two hundred degrees to nine hundred degrees before stopping.

It seems that the maximum temperature of this furnace is the same, unless there is higher energy carbon or the furnace needs to be modified to further increase the furnace temperature.

The iron buried in the carbon in the stove quickly burned red, and Li Zhenhua couldn't wait to hold him with clamps.

Taking it out and putting it on the anvil, Li Zhenhua picked up the heaviest small hammer and began to shape the red-hot bow board.

Just when Li Zhenhua was knocking with the hammer, he didn't feel anything at first.

But the more he got to the end, the smoother he felt. Compared with when he swung the sledgehammer before, he didn't know how many times his craftsmanship had improved, and he could be in the best state unconsciously.

Just as Li Zhenhua continued to hit the iron, a subtitle appeared in his eyes again.

What was shown above made him very happy, because he finally knew the current state of Ingenuity.

'Ingenuity: the brain says I can do it, the eyes say it's too easy, the hand says: It's a piece of cake, I can do it too (millimeter level)'

It was also from this point that Li Zhenhua had the most intuitive concept of ingenuity.

Although I know that the ingenuity has already played a role, but now that the fire has been fired and the iron has been struck, the knife in my hand must be finished.

The hammer in Li Zhenhua's hand kept beating on the raw material, hitting several or a dozen hammers.

As the temperature of iron decreases, the hardness also increases, and the hammer will not move.

The iron should continue to be sent into the stove to burn red, and then taken out to be beaten.

When Li Zhenhua knew what he was holding, he turned his attention to the air hammer that was standing aside.

Li Zhenhua also wanted to try to see if this ingenious function could work when using large-scale equipment.

Put half of the billet in the shape of a knife into the furnace again, and continue to burn the billet.

Li Zhenhua turned around and came to the side of the air hammer, and reconnected the three-phase electric wire of the air hammer to the switch. When the power was turned on, the asynchronous motor of the air hammer started to operate, and the air was continuously compressed into the cylinder.
The hammer head of the air hammer kept moving up and down, and Li Zhenhua adjusted the height of the hammer drop according to the hints from his eyes.

Since his eyes gave hints, he knew that the function of ingenuity can also be used with an air hammer.

At this point, the preparatory work has been done. Li Zhenhua clamped the blank out, sprinkled some borax, removed impurities with an iron brush, then put it under the air hammer, and stepped on the foot switch.

The billet was hammered by the air hammer, and the hand was constantly adjusting the billet.

From the eyes giving suggestions, to the brain receiving and issuing instructions, to the hands receiving instructions and starting to move, a series of processes form a closed loop.

Under Li Zhenhua's hands, the billet was slowly hammered into shape.

The shape of the watermelon knife is still very easy to forge, and it was made by Li Zhenhua with blacksmith techniques.

If you directly use a large bow sub-board to directly burn red and anneal to knock it out, then draw a knife shape on it, and cut it out with an angle grinder, it will be made faster.

Li Zhenhua took the knife blank, put him into the stove again, and continued to burn red.

This time he picked up the small hammer and used it to shape the knife blank.At this point, it can be said that it is almost the last step.

After finishing the shape of the knife, the next step is to quench the knife. It can be said that this step is also a test of a blacksmith's skill.

As for whether to temper it after the quenching is completed, it depends on whether the blacksmith has that skill.

If you don't have the skill of tempering, it is better to keep the knife in the state after quenching.

The knife blank was still burning in the stove, and Li Zhenhua went to the warehouse again.
