Starting Off With A Blacksmith Workshop Chapter 5

Li Zhenhua was rummaging in the house. He remembered to put away all the things he needed before leaving for school.

He quickly found several buckets of sealed liquid, and when he saw through the plastic bucket, the liquid inside flowed very slowly when he moved it.

Li Zhenhua took out a bucket, opened the lid and looked inside.

Seeing that the barrel contained a black viscous liquid, Li Zhenhua checked the contents of the barrel.

After finding that there was no problem, he nodded in satisfaction and walked out of the room with two buckets of liquid.

Back next to the stove, there is a rectangular iron sink next to the stove.

At this time, there was nothing in it, so Li Zhenhua opened a bucket and poured it into the sink.

Just when Li Zhenhua was about to pour the second bucket, his analytical eyes gave another hint.

A line of prompts appeared in his line of sight:

'A mixture of diesel oil and engine oil, which can be used as a coolant for steel quenching.

The current ratio of the two is not the best ratio, please continue to add oil to it. '

This reminder made him feel that having an analytical eye would be of great benefit.

For such a problem of quenching coolant, this eye can give the best ratio.

Li Zhenhua returned to the room and took out a 2L red small bucket inside again, which contained engine oil.

This is the used motor oil that Li Zhenhua bought from the car repair shop in the town before.

It was also because there was no place to dispose of the waste engine oil at that time, so it could be taken away by Li Zhenhua.

If this is left until now, how can there be no place to dispose of these waste engine oils.

Returning to the sink, Li Zhenhua unscrewed the lid of the keg.

Then he poured waste engine oil into it, and his eyes gave hints from time to time.

'Oil difference: 1200ml, 800ml...100ml, 40ml, 1ml.

Too much engine oil, please add diesel; current diesel difference: 2ml. '

It turned out to be too fierce, which also led to missing the best ratio.

I added some diesel oil to it little by little, so as to save more diesel oil.

Finally, in the hands of Li Zhenhua, the quenching coolant was adjusted to the best ratio.

The quenching thing was ready, and now only the actual operation remained. Li Zhenhua returned to the stove and took out the knife blank.

Looking at the hint given by the eyes, the temperature of the knife blank is slightly higher at this time.

Li Zhenhua could only stand there with the knife blank between his arms, waiting for the temperature to drop, and he was also ready to insert the knife blank into the quenching coolant at any time.

The temperature finally dropped to the optimal temperature, Li Zhenhua did not hesitate, and the knife blank was directly inserted into the coolant.

The coolant in the sink caught fire directly. Along with the flames, the air smelled of burning oil.

'Please take out the knife blank, count down ten seconds, 3, 2, 1. '

Li Zhenhua immediately took out the knife blank, and the quenched knife blank didn't look very good at this time.

The surface of the knife blank is black, which is extremely ugly.

Li Zhenhua took the knife blank in his hand and observed it carefully. At this moment, a word appeared next to the knife blank.

"Watermelon knife (semi-finished product),

Length: 430mm, Width: 45mm,

Total weight: 750g, hardness: 62,

Toughness: Tempering is not completed, the data of this item is incomplete, and tempering process is required. "

Li Zhenhua didn't expect that he just wanted to test another of his loaded functions.

But since he made this watermelon knife by himself, the subsequent development is more and more out of his expectation.

If this watermelon knife is really completed according to the prompts of the analytical eye.

Not to mention killing watermelons, even killing people is a piece of cake, maybe this watermelon knife is of better quality than the small daggers generally sold on the market.

In fact, Li Zhenhua also wanted to know what he would do with this watermelon knife in the end.

So Li Zhenhua intends to strictly follow the prompts of the Analytical Eye.

'Please configure the tempering solution next, raw materials: diesel oil, engine oil. '

Li Zhenhua strictly followed the prompts and prepared a solution for tempering.

Li Zhenhua, a family blacksmith, of course knew how to temper the fire. He took out a thin rectangular bucket and poured the solution into it.

Then he squatted the barrel on top of the stove, and Li Zhenhua carefully controlled the fire.

Until the temperature of the solution is burned to close to the ignition point.

Li Zhenhua maintained the temperature and fixed the knife blank on the solution bucket with iron wire.

Then there is a long two-hour wait. The knife blank is placed in the solution and maintained at 220 degrees Celsius for more than two hours.

Li Zhenhua finally took him off the stove.

The next step is to continue to wait, waiting for the knife blank to slowly cool down in the solution.

When the knife blank drops to normal temperature, the tempering process is considered complete.

Quenching makes the knife blank hard, and tempering makes the knife blank tough. A watermelon knife is made.

Let Li Zhenhua do it directly according to the weapon level.

The sky darkened while Li Zhenhua was keeping the watermelon knife warm, and Li Zhenhua didn't intend to keep guarding it.

Instead, let it cool down naturally. Father Sun went down the mountain, and it was time for Li Zhenhua to eat again, but for him, this day's experience was simply amazing.

He just sold a sickle, and actually sold himself a gold finger.

Li Zhenhua picked up a large amount of noodles with chopsticks and put them into his mouth.

"It seems that my life is to be a blacksmith. If I don't become this blacksmith, I feel that this golden finger will leave me immediately."

After eating, Li Zhenhua walked to the stove and looked at the knife blank in the tempering solution.

The dialog box in the eyes shows the temperature of the knife blank at 43°C.

Seeing this temperature, Li Zhenhua knew that he could actually fish it out of the solution.

Putting on the gloves, he took the wire hanging from the side of the bucket and fished the knife out of the bucket.

I saw the mixed oil solution all over the knife body, put the knife blank on a rag that had been prepared a long time ago, and wipe off the solution on the knife blank with the cloth.

The color of the knife blank appeared in front of Li Zhenhua's eyes. The color of this knife blank was still that kind of silver gray, and it was a little black.

Li Zhenhua looked at the hint in his eyes.

"Watermelon knife (3/4 finished),

Length: 430mm, Width: 45mm,

Total weight: 750g, UU Kanshu www.uukanshu. com hardness: 62,

Toughness: good (the value of this item is more complicated, and the specific value will not be quantified for the time being). "

The knife blank has been forged at this time, and the next step is to cut the V and sharpen the knife blank.

After these two procedures are assisted by machines, it is already very convenient for blacksmiths.

However, it is still somewhat difficult to do these two processes well to the point of blowing hair and breaking hair.

Li Zhenhua came to the table next to the anvil and put the knife blank on it.

Originally, he wanted to use a caliper to find the center of the blade, and then draw the line to open the V on the belt sander.

But the Analytical Eye played its role once.

Li Zhenhua didn't need to draw the line anymore, he went to the belt sander and clamped the knife blank on the fixture.

Turn on the machine by hand, the belt machine turns, and Yang Yu holds the clamp with his hand, and sends the knife blank to the belt machine.

When the knife blank touches the belt machine, the friction between the belt machine and the knife blank produces a lot of iron filing sparks.

The knife blank gradually formed a V shape in Yang Yu's hands, and it became more and more decent.

Wait until the eyes finally show the prompt, and the high-waist flat grinding V is completed, and the next step is the next step, the second sharpening by hand.

After completing this step, the entire watermelon knife is no longer the same color as before. When the V was turned on, the belt sander had already worn out the color of the steel.

Now it has become half of the bright silver, as long as the remaining point is not open, it is still the same color as before.

Li Zhenhua took the knife blank to a corner of the yard, where there was a long bench.

There is a millstone on the bench, which is said to be older than his age.

Li Zhenhua sat straddling the bench, took the knife and began to sharpen it little by little.
