The pig iron with higher carbon content produced in the iron-making furnace is then refined into wrought iron with lower carbon content.
Zhao Ziliang did not understand the technology of iron and steelmaking, so he asked Liu Hongyi: "Now that pig iron has been refined, , then why do we need to refining it?
Isn’t it enough to just use pig iron to make steel?”
Liu Hongyi explained: "General, steelmaking requires not only pig iron, but also wrought iron.
Wrought iron is obtained after refining pig iron."
Liu Tianci on the side also said: "Yes, the steel-making method used by the general villain is the steel-filling method.
The raw materials required for the steel-filling method are not only pig iron, but also wrought iron."
Zhao Ziliang looked at the craftsmen who were throwing the pig iron blocks into the iron-making furnace for refining, and asked: "Why do we need to use the steel filling method?
What are the benefits of the steel filling method?"
Liu Tianci cupped his hands and said: "General, the Hengdao and Modao used by ordinary soldiers are first cast into knife embryos by pouring steel.
The blades are hard and the blades are sharp.
There are many methods of steelmaking and other steel-making methods.
Advantages: First, the smelting time is shorter; second, both wrought iron and pig iron are turned into steel, and the output is increased.
Plus; third, it can remove more impurities and improve the quality of steel; fourth, the operation is simple, easy to master and learn.
If you want to get steel with different properties, you only need to adjust the ratio of pig iron and wrought iron.
For example, it is hard.
The lower the degree and the better the toughness of the steel, the fewer impurities it contains and the harder it is.
The higher the steel and the lower the toughness, the higher the impurity content.
Generally, the swords used by high-level generals use a mixture of these two steels as materials.
Sword-casting and sword-casting masters then use the skills of steel-making and partial quenching as the basis.
It is then forged using the techniques of covering the earth, burning the blade, and covering the steel with steel.
The specific forging sword It's not our business, but the swordsmith's business.
We are only responsible for making steel, but the steel embryos we make using the steel-filling method only need to be sharpened to become semi-finished swords.
The swordsmiths simply give them Attach the handguard, decorate the blade, and add the scabbard to the scabbard to make it a finished product.”
Zhao Ziliang thought thoughtfully and asked: "So this general will have to find some craftsmen who can forge swords to set up a special arsenal to obtain finished swords, guns, swords, sticks and other weapons."
Liu Tianci nodded and said: "Yes, General" Zhao Ziliang immediately ordered Wang Can: "Use flying pigeons to send a letter to Suiye City and ask Fu Kun to bring his disciples to Xilin to guard the capture.
This general will set up a weapons supervisor and let him be the general."
As the chief inspector, he is fully responsible for the casting of various weapons in the weapons inspection department.
In addition, he selects some blacksmiths from among the people from the mainland to join him."
Wang Can raised his hand and agreed: "I understand, I will take care of it later."
The next day, after saving enough raw materials, the steelmaking plant began to use the steel pouring method to make steel.
The pig iron was melted first, and then the molten iron was poured on the wrought iron to allow the carbon impurities in the pig iron to penetrate into the wrought iron.
Among irons, pig iron becomes steel due to decarburization, and wrought iron also becomes steel due to the infiltration of carbon.
Moreover, the carbon, silicon, and manganese in pig iron react with the oxides in the wrought iron to remove impurities. , which improves the quality of steel.
Zhao Ziliang watched pot after pot of molten steel being poured into the sand mold to cool, and finally turned into knives, swords, arrowheads, gun heads, and axes.
These were all semi-finished steel weapons.
He felt extremely happy. .
These semi-finished products are the finished products of the steel factory.
They will be sent to the weapons supervisor for further sharpening, processing, and decoration in the future, and they will become pieces of weapons.
These are used by ordinary soldiers and low-level officers, while mid-level captains and captains The weapons used by senior generals will be forged by specialized blacksmiths and blacksmiths.
Fu Kun was a descendant of the Han people whom Zhao Ziliang met when he was on a mission to the Zhaowu Kingdom.
He used a piece of Tianshan cold iron and combined Eastern and Western forging techniques to forge a sharp and extremely tough sword and gave it to Zhao Ziliang. .
Now he is leading his landmen from Suiye City to Xilin to guard the capture.
Fu Kun's arrival made Zhao Ziliang extremely happy.
Under his auspices these days, a weapons factory was built next to the steel factory to specialize in manufacturing weapons, crossbows and arrows, and the Han people who had migrated there were also Among them, some blacksmiths and casters were recruited.

As soon as Fu Kun and his apprentices arrived, Zhao Ziliang handed over the weapons supervisor to him.
Fu Kun was extremely moved by Zhao Ziliang's trust.
He knelt down and said, "General, I will definitely live up to the general's trust and love and create more sharp and durable weapons for the general."
"Alright, don't call yourself a villain anymore.
You are now the Chief Superintendent of the Weapons Supervisor.
You are a person with status.
How can you call yourself a villain like the others?"
Zhao Ziliang said and helped Fu Kun up.
"Yes, I will obey my orders."
"That's right."
Zhao Ziliang nodded and said, "Our weapon forging skills are kept secret, so we must prevent the forging skills from leaking.
So on the one hand, you must prevent enemy craftsmen from sneaking in, and you must always take precautions. consciousness.
The forging skills should also be divided into several processes.
Each person or each group of people is responsible for one of the processes.
No one is allowed to move around the workshops of other forging processes.
In this way, even if a craftsman sneaks in, it will not be easy to control the entire set of skills.
I’ve learned all the procedures.”
Fu Kun thought about it carefully, his eyes lit up, and he said: "The general is brilliant.
If the forging skills are divided into several processes, it will not only effectively prevent the leakage of the skills, but also improve the forging efficiency and shorten the forging time."
Zhao Ziliang smiled and said: "I didn't expect you to discover the secret so quickly.
Yes, yes, yes, the production of weapons takes relatively less time, but the production of crossbows and arrows takes much longer.
Many, some crossbows take one or two years to complete.
Moreover, once a war occurs, the number of arrows will not be enough, and the loss will be the most serious.
Therefore, the general is wondering whether the quantity of bows and crossbows should be made larger each time, and it must be done continuously every day.
In addition, you We are also trying to see if we can simplify the manufacturing technology process.
Due to the large number of arrows required, I think the process of making arrow shafts and installing tail feathers can be left to the local people.
As long as they are given a unified standard, such as the same thickness and length, the people can do it at night.
You can do it at home, we are here Set up a purchase point here.
How much does a qualified arrow shaft cost?
After the people make it, they can sell it to us.
I used to do this in Hexi.
I collected hundreds of thousands of arrow shafts in a month.
We only All you need to do is install the arrows made from the mold."
Fu Kun said: "The ideas mentioned by the general are all very good and can be adopted and used.
I will definitely comply with them."
Zhao Ziliang patted Fu Kun on the shoulder: "Okay, I'll leave the weapons inspection to you.
I'm relieved.
Now we have more than 32,000 soldiers in Beiting.
The weapons and crossbows made this year should be enough for two years.
To be able to sustain a two-year war, you need to calculate how many weapons, crossbows and arrows you need to make.
Also, after the weapons, crossbows and arrows are made, you must pay attention to maintenance to prevent these weapons from developing before they are distributed to the soldiers.
Rusty" "I understand" Fu Kun added: "General, ordinary soldiers, military commanders and junior captains are more than capable of using the steel we have trained to forge weapons.
The sharpness is much higher than the ordinary weapons of any country in the world today, but if the weapons used by our senior generals are If you can use iron as an auxiliary material, the forged weapons will be sharper and tougher."
"What kind of iron is iron?"
Zhao Ziliang frowned and asked in confusion.

Fu Kun explained: "General, bin iron is produced in northwest Tianzhu, Jibin, and Persia.
It has natural patterns such as spiral flowers and sesame snowflakes.
More than a hundred years ago, the Persians used it to make a scimitar called Damascus. , extremely sharp and beautiful, craftsmen often inlaid gems on the handles and scabbards of the knives.”
Isn't this wootz steel?
Zhao Ziliang understood that the wrung iron mentioned by Fu Kun meant wootz steel.
He couldn't help but ask: "Apart from Persia and Jibin, is there also this kind of wrought iron in northwest Tianzhu?"
Fu Kun nodded and said: "Yes, the output is quite a lot, but now Tianzhu is in constant war and chaos, and the output of iron and iron has been greatly affected.
Persia has now become a big food country, and the big food country is now also in chaos. has increased, so the production of iron and steel in various places is declining, and the price is also rising.”
Zhao Ziliang thought for a while and said: "Since iron can be used as an auxiliary material for the weapons used by senior generals to make the weapons sharper and tougher, then we have to find a way to get it.
Let's do this.
There are caravans from Xilin all year round.
After that, you can contact the leaders of the caravan and ask them to find a way to get the iron.
You can take care of it yourself if we buy it at a high price."
Fu Kun bowed his hands and said: "General, trust me, I will not disappoint you.
General, as far as I know, the reason why Bintie is Bintie is not because it contains special envoys, but because it is made of A thing called a crucible is used as a container to smelt it, but not all crucible steel can smelt iron, which requires special smelting skills."
"Oh, so that's it."
Zhao Ziliang was quite surprised.
He didn't use smelting technology.
He always thought that the Damascus scimitar was forged from special steel containing different metal elements, but he didn't expect it to be because of the unique metallurgical technology.
Zigang or binite.
Thinking of this, Zhao Ziliang said to Fu Kun: "This general knows about this.
I will find a way to get you the smelting method of crucible steel and let you smelt the iron."
Fu Kun was overjoyed.
He cupped his hands and said, "Thank you very much, general.
I will wait for the general's good news."
After Zhao Ziliang left the weapons supervisor, he immediately found Wang Can and ordered: "If you add iron to weapons and then forge them, the sharpness and toughness of the weapons can be greatly improved.
Today, the only place rich in iron and iron is northwest Tianzhu." , Dashi Country and Jibin, Dashi Country and Jibin are too far away from us, we have to find a way to get the smelting method of iron and steel from northwest Tianzhu."
Wang Can said: "In this case, we can send people to do business in northwest Tianzhu under the guise of a caravan, secretly bribe the local casters, and obtain the smelting method of iron iron."
Zhao Ziliang thought for a while and said: "This method is feasible, but there must be skilled blacksmiths among those sent there.
You must see with your own eyes how they smelt iron.
Only in this way can you learn the smelting skills.
Now you go Discuss with Fu Kun and ask him to send a shrewd apprentice to accompany the caravan."
Wang Can cupped his hands and said: "I will finally understand":
