Cao Chong was not particularly satisfied with the quality of the heavy armor, but Cao Chong did not blame Guo Xiao.
To be honest, Guo Xiao has tried his best.
With all his might, it can be seen from his haggard appearance.
But Cao Chong can not blame Cao Chong, but he can't help but put this matter on hold.
Heavy armor can't be used like this.
Cao Chong asked the two strong men in front of him to put back the heavy armor, turned his head to Guo Xiao and said, "Let's go, let's go see the ironmaking workshop." ” Cao Chong didn't have any research on ironmaking, but he had also watched documentaries about ironmaking, and he still knew some of the most basic ironmaking techniques in later generations, and perhaps he could improve the current ironmaking techniques.
During this period, it was estimated that there was still more iron than pig iron, not to the extent of hard iron, and as for steel, although it existed, the output was definitely not high.
If Cao Chong can produce steel.
Well, that's a little scary.
If there is a thirty catties of heavy armor, the defense of the previous thirty kilograms and fifty kilograms of pig iron heavy armor is several times better.
Moreover, with a sword made of steel, the opponent's cast-iron armor can defend against it Not at all What Cao Chong wants is equipment crushing.
But Cao Chong thought about it, and he was still a little uncertain in his heart, and he didn't know if the little knowledge about ironmaking and steelmaking in his mind could inspire the blacksmiths here.
You must know that although Cao Chong watched a documentary in later generations, after a long time, he only had some shallow impressions, not to mention that Cao Chong was completely bored watching this thing at that time, and it was unknown how much he could remember.
But It can only be counted as one step at a time.
When I entered the iron-making factory, the sound of iron-making in my ears gradually became louder, and the temperature around me also increased little by little, which seemed to drive away the chill of early spring.
Step into the ironmaking workshop, in this factory, let's just say the factory.
In this workshop, pig iron is forged.
That is, iron ore is smelted into raw iron.
Looking at the two three-person tall iron-making furnaces in the factory, Cao Chong looked thoughtful.
In the documentary in his head, iron smelting in later generations was generally blast furnace iron smelting.
However, the equipment inside the blast furnace is very complicated, and it is very unrealistic to build the blast furnace of later generations in this era.
But Cao Chong knew the principle of blast furnace ironmaking.
Fe2O332Fe32{High Temperature} Fe3O423Fe22{High Temperature} CO22{Ignite} c22{High Temperature} These four formulas are the principles of blast furnace ironmaking, and to make iron, in addition to high temperature, it is necessary to increase the contact area to make iron ore react better.
This is why the height of the blast furnace can increase the efficiency of ironmaking within a certain range. so Can I get the blacksmiths to raise the furnace a little higher?
Cao Chong had all the thoughts in his heart, but he didn't stay in this factory for long.
Cao Chong continued to walk forward, and after the forged pig iron was cooled and shaped, it would be handed over to the next workshop, where a blacksmith and an apprentice were operated by hundreds of people, and there were dozens of forging tables.
Most of the banging sounds came from this factory.
Heating forging, which is a step that makes pig iron more tough.
Cao Chong didn't stay in it for long, and continued to walk to the next plant.
In this workshop, those molds that have been shaped and forged with toughness are added with some decoration, and they are connected, so that a piece of steel is added to the outside of this armor to make chain mail.
Let this heavy armor be covered with a layer of steel armor.
Steel, in this era, appeared even earlier in the Qin Dynasty.
But the reason why the heavy armor is not all made of steel is entirely because steel is difficult to make, if you use one or two sets of armor made of steel, it is fine, dozens of kilograms of heavy armor, five hundred sets, if each set is made of steel, it is an impossible thing.
In this era, the main steelmaking processes were the lump iron carburizing method and the steel frying method.
The raw material of frying steel is pig iron, and the key point of operation is to heat the pig iron to a liquid or semi-liquid state, and use blasting or sprinkling concentrate powder to oxidize silicon, manganese and carbon, and reduce the carbon content to the composition range of steel and wrought iron.
Not only is the operation troublesome, but also the steps are numerous, the raw material value is expensive, the production time cycle is even longer, and the output is not high.
This is also the reason why it is not possible to cast heavy armor entirely out of steel.
But Cao Chong knows another technology.
There is the steel-filling method that will be invented a hundred years later, and the crucible steel-making method that will only appear in the seventeenth century.
The steel filling method selects iron ore with a relatively high grade to smelt high-quality pig iron, and then pours liquid pig iron on wrought iron, and after several degrees of smelting, the iron is carburized into steel.
Since pig iron and wrought iron are "stayed" together, the steel smelted is called "staying".
The steel filling method shortens the smelting time, increases the productivity, increases the yield of steel, purifies the metal structure, and improves the quality of the metal.
And the steel filling method is easy to operate and easy to master.
If you want to obtain steel with different carbon contents, you only need to mix pig iron and wrought iron in a certain proportion and smelt them.
If you can let them know the steel filling method, maybe all the heavy armor can be cast from steel.

As for the crucible steelmaking method, it is a method of melting metal in a graphite clay crucible to become molten steel.
But it's easier said than done, and besides, Cao Chong doesn't know much about it.
They don't know what to do with graphite clay crucibles, but if you say that pig iron is poured into wrought iron, after a few smelts, these blacksmiths must know what to do.
Since this matter had been decided, Cao Chong said to Guo Xiao: "These blacksmiths, are there any skilled or respected people?"
In fact, Cao Chong is almost saying the same thing, basically those who are highly respected are highly skilled.
If you don't have great skills, who will respect you Especially in the blacksmith industry.
After knowing that Cao Chong was going to meet someone, Guo Xiaomashan asked someone to find an old man who was over half a hundred years old.
This old man has silver-white hair, but his body is very strong, and he is not old, and his muscles are coiled and cruined.
His steps were very steady, coarse cloth clothes, and when he saw Cao Chong, he quickly knelt down and saluted.
"The grass people have seen nobles."
Before the old man knelt down, he was helped up by Cao Chong.
"How to call the elderly" Being helped up by this young nobleman, the old man's face was a little rosy with excitement.
"Caomin's surname is Zhao, you can call me Old Man Zhao."
Cao Chong smiled on his face and said, "Old Zhao, you are the person with the most superb iron-making skills here."
Although there is only one word difference between Old Man Zhao and Old Zhao, the difference is that they are separated by thousands of rivers and mountains, Old Man Zhao has a smile on his face, his eyes look at Cao Chong, and he feels more happy and respectful.
Respect is mutual, even if your status is much higher than his.
"It can't be said that the skills are superb, it's just a few more unique skills."
This old man is quite good at talking, and it seems that it is not for nothing that he can become a respected member of the blacksmiths.
"Then you can fry steel" If he didn't even know how to fry steel, Cao Chong felt that it was useless to hand over the steelmaking to him.
When Old Man Zhao heard the three words of the steel frying method, he looked at Cao Chong with a look of surprise, and said with some excitement: "The noble man also knows the steel frying method."
Cao Chong nodded lightly.
"Old Zhao hasn't answered Ben Hou's question yet."
Old man Zhao hurriedly said to Cao Chong: "The steelmaking method is not a scarce technology, not only the little old man, but also many craftsmen. ” Cao Chong nodded, and said to Old Man Zhao with a smile: "I have a new steel-making method, which is several times better than the steel-frying method, do you want to give it a try?"
Steelmaking hair that is better than the frying method If someone else said this, he would definitely mock one or two.
But the one in front of him was none other than him.
This is a nobleman So he chose to believe.
However, Old Man Zhao's eyes were a little strange at this time.
Elegant Isn't it pampered?
How can you still know how to make steel, this is a cheap job.
It's weird However, this idea was only fleeting, and he was immediately attracted by the new steelmaking technique that Cao Chong had said
