The steel smelting technology of the current era is very backward, and the hardness and toughness of steel are mainly improved by repeated folding and beating.
But this method is time-consuming and laborious.
My father-in-law and my uncle knew about the quenching process, but they only had a superficial understanding of it and didn't know the principles at all.
After quenching, the hardness of the iron is indeed increased, but it also becomes brittle and is very easy to break.
This process is fine for making some large items, but it is not suitable for making tools such as kitchen knives and hoes.
Because ironware these days is a very valuable item, especially in rural mountain villages, if someone buys a kitchen knife or a hoe, it is equivalent to purchasing a large item that may be passed down for several generations!
If it breaks easily, how can it be passed down?
So, last night, he used more advanced cold forging technology to make a kitchen knife. It is not only very hard, but also has good toughness. The surface is black and shiny, and it looks great!
As for why he suddenly has advanced blacksmithing skills?
He had already thought of the reason and learned it from books!
Anyway, my father-in-law and my uncle couldn't read a single word together, so it was impossible for me to bring the book to them.
Zhang Lie is a person who knows the goods and is very obsessed with blacksmithing. After seeing a method that can improve the quality of ironware, he felt like a cat scratching his paws and wanted to learn it quickly!
After waiting hard all morning, when he heard Lin Xu getting up, he quickly pulled Lin Xu into the blacksmith shop.
"Brother-in-law, what on earth was going on with the cold forging you were talking about last night?"
"The so-called cold forging means to forge the material directly at the crystallization temperature... ahem, to put it simply, it means to directly forge the unheated blank..."
Before he finished speaking, the old blacksmith walked in.
"Lie'er, don't keep pestering me with questions..."
"Dad, I am asking my brother-in-law for blacksmithing skills..."
"Can I ask for advice on blacksmithing techniques? Can I ask for advice on this technique casually?"
The old blacksmith suddenly raised his voice several times!
"Brother-in-law is not an outsider! Besides, I..."
"It doesn't matter if you're not an outsider!"
The old blacksmith interrupted him again: "Our craftsmen can only pass on our skills to our sons and apprentices, and no one else is allowed to pass them on! This is a rule set by our ancestors!"
Of course Zhang Lie also knew this rule, but he wanted to learn the cold forging technique so much that he said directly: "Then I will be my brother-in-law's apprentice!"
After saying that, Zhang Lie pretended to give Lin Xu a apprenticeship ceremony!
Lin Xu quickly grabbed him!
"Dad, brother, rules are dead and people are alive. We are all a family, so there is no need for this."
Lin Xu said with a bitter smile.
"No, if you want to teach him how to blacksmith, you must accept him as your apprentice, otherwise you won't teach him."
The old blacksmith's attitude was very tough.
"It's not appropriate for my uncle to be my apprentice. It's too disturbing..."
"It's a bit awkward...but our Zhang family has been blacksmithing for generations, and the ancestral rules cannot be changed."
The old blacksmith thought for a while, and then said seriously: "Let's do this, uncle, if you really have this intention, just set up a formal apprenticeship ceremony, but it must be written clearly in the letter. If Zhang Lie doesn't ask you in the future,
With his permission, I passed on the blacksmithing skills you taught me, so you can do whatever you want with him! Even if you beat him to death, our Zhang family will never report him to the official!"
Lin Xu smiled bitterly: "Dad, you really don't have to do this..."
"If you don't even agree to this condition, then don't teach him. Lie'er, come out."
The old blacksmith said solemnly.
"Oh, dad..."
Zhang Lie was coy, like a big girl, unwilling to go out.
"What? You want to get kicked, don't you?!"
The old blacksmith glared and scolded!
"Okay! Okay! I agree!"
Seeing the old blacksmith's insistence, Lin Xu had no choice but to take a step back: "Dad, just do as you say!"
For my uncle, once he masters the cold forging technology, he can definitely take the blacksmithing craft to a new level!
However, this height is also limited. Because there are no modern machine tools, we can only perform some simple cold forging processing for the time being.
With his knowledge base, as long as he has enough time, he can create a process that is much more advanced than cold forging.
For example, if you just make some special alloy, its performance will be many times higher than that of cold forged steel!
It’s completely a dimensionality reduction attack!
Therefore, he is not afraid of Zhang Lie spreading the cold forging technology at all.
In addition, if he wants to settle down in this era, steel smelting must not be bypassed. For example, the core components of the repeating crossbow he is about to make must be made of steel.
But he didn't have that much time to spend in the blacksmith shop, so he had to find someone to do it for him. This chapter has been completed!
