Chapter 282 The birth of steel, unmatched sharpness
Guo Zhang was stunned when he heard this.
"I?
Then Guo Zhang reacted and knelt down.
"Meet Your Majesty the Emperor. Year
The two people beside him were also shocked instantly. This young man is actually the emperor of Daqin today? The two immediately knelt down.
Li Cang immediately knelt down to receive the order when he heard Zhao Tuo's order.
"Yes, Your Majesty.
Zhao Tuo looked at several people.
"Get up."
The four people all stood up when they heard Zhao Tuo's words, but except for Li Cang, the other three were very frightened.
Especially Guo Zhang, who had just chatted casually with His Majesty the Emperor for so long.
"Guo Zhang, your forging method is correct, but... there is still a lack of temperature. You can make a circular hot furnace. It can be used to further increase the temperature... In addition, charcoal powder can be appropriately added during forging...
"Besides that, although iron ore is difficult to soften, it is not possible to add some other things, such as certain ores.
Guo Zhang listened to Zhao Tuo's words, his expression gradually became serious, and then he fell directly into thinking.
Naturally, Zhao Tuo could not explain the principle, and naturally he could only make continuous progress in the forging process through some side-by-side attacks.
After listening to Zhao Tuo's words, Guo Zhang actually pleaded guilty and went directly to the forging furnace to experiment.
Zhao watched this scene and pondered, in fact, there is a better way, that is to use coke as fuel, but the coal mine has not yet started desulfurization.
Coal is bound to be better than charcoal as a fuel, but most coals contain sulfur, a substance that makes iron brittle.
Once the iron becomes brittle, it is very easy to break in the process of use.
In this way, it is not as good as a bronze weapon, so coal must be converted into desulfurized coke before it can be used as a combustion material in the smelting process.
As for the desulfurization of coal, it is not complicated. At present, there is a simple and extremely easy way to achieve it, that is, using limestone.
Limestone can react with sulfur in coal to remove sulfur from coal and turn coal into coke.
With coke, the problem of steel is naturally not so difficult.
The combustion of coke can easily reach the melting temperature of pig iron, and after the pig iron is melted, as long as appropriate charcoal powder is added, it can be kept in liquid state, or it can be kept stirring, and finally cast into weapons and utensils.
After a while, Guo Zhang walked back again, his face full of joy.
"Your Majesty, I re-smelted it according to the method you said, and found that the iron and stone have indeed changed.
Li Cang, Zhang Liang and others were greatly surprised when they heard Guo Zhang's words.
It is extremely difficult to know the smelting of iron tools. This Guo Zhang craftsman is also able to make iron tools because his ancestors have brought everyone out.
Unexpectedly, Zhao Tuo's few words have improved this process.
When Zhao Tuo and others left, Guo Zhang was sent to the outside of the valley.
In this line, Zhao Tuo is very satisfied. Although there are not many iron tools in Daqin at present, the technology is sufficient for production. After that, a large number of constructions are no longer a big problem.
As for the ore, there are not many found here alone.
Besides Linzi, there are also a lot of Handan, which Zhao Tuo has heard from Guo Zhang.
It is precisely because of this that Handan has so many craftsmen.
After returning to Jiaozhou County, Zhao Tuo called the ministers who followed, wrote the technology of limestone desulfurization on paper, and then asked them to finish the coal mine.
"Have someone send the letter there immediately, and then order the supervisor to send someone to start production.
"Yes, Your Majesty."
With the delivery of the Daqin Post Station, the letter soon reached the supervisor of the coal mine.
After learning that this is the will of His Majesty the Emperor.
He didn't dare to delay for a moment, and immediately let people start the experiment according to the method written above.
It didn't take long for the first batch of coke to be produced, and then this batch of coke was sent to Linzi non-stop.
After Guo Zhang in the valley got this batch of coke, he immediately started a fire.
The forging furnace at this time has also changed its appearance. According to Zhao Tuo's description, a new furnace with an oval 930 shape replaced the previous forging furnace.
"Put the iron stones below and spread them out.
"The coke is placed above, and iron stones are piled up again, coke..."
Then the raging fire burned, Guo Zhang looked at the stove nervously.
After firing for a while, Guo Zhang asked someone to open the small opening under the stove.
In an instant, a fiery red liquid like lava flowed out.
Guo Zhang was instantly ecstatic when he saw these liquids, and the craftsmen around also exclaimed.
"It can actually melt directly!"
"This way of forging must be light, and quickly divide it and place it on the forging table! 35
With the hammering of the craftsman and the addition of charcoal powder, iron swords were created one by one.
After finishing, Guo Zhang picked up one of the handles.
Then he directly slashed at another long sword placed next to him.
"Crack. 35
With a sound, the other long swords snapped, and the cuts were smooth.
