Straight man of steel

Chapter 31
Before I got home, the fragrance was already wafting out.

The cook at home has prepared meals and is waiting for them to return.

This feeling is very good.

Iron ore needs to be crushed and then put into a crucible for smelting, and it takes five or six hours to smelt and turn into water.

After eating, Zhang Yuan also joined the iron ore knocking team. The ten pieces of equipment had to be completed by himself. It is not a bad thing to get used to it and exercise your arms in advance.

After a few days of getting along, these big men who can be shirtless in winter have an inexplicable sense of trust in Zhang Yuan, which may be caused by the wages they have never seen in their entire lives, or it may be that Zhang Yuan has always been with them. People from places.

This kind of trust and intimacy is what Zhang Yuan wants to see. He doesn't want someone to report his actions to Zhuo Wenjun and Zhuo Wangsun every day.

Looking at the iron ore in the crucible waiting for it to be smelted into molten iron, only two or three people are needed, Zhang Yuan arranged for six people to keep watch at midnight, and he went to the bedroom to rest.

One furnace is for smelting pig iron, and the other is for smelting wrought iron.

After Zhang Yuan woke up the next day, the first batch of flat pig iron billets had already been placed aside.

Because the melting point of pig iron is lower than that of wrought iron, Zhang Yuan wants to pour wrought iron on top of the pig iron. According to normal theory, the transfer of carbon components between them will be more rapid and effective at such a high temperature.

The process of carbon infiltration is also the process of melting pig iron slabs with molten iron.

Moreover, in order to be able to cast multiple times, the mold for holding the iron billet is also specially made. It is almost two yellow mud square sticks with grooves in the middle to sandwich the pig iron billet. Zhang Yuan can let people move up and down, or even rotate. to adjust.

The preparations were all done, the crucible for smelting molten iron was already dazzlingly bright, and a pile of sand was poured under the pig iron slab to prevent the dripping molten iron from being wasted. Zhang Yuan directed two of the craftsmen to start this crucial process. An important process.

"Come on, it's not too difficult. Let the molten iron be poured evenly on the iron plate, and both sides should be poured, and it should be poured several times."

Although everyone didn't know what Zhang Yuan was going to do, they still proceeded meticulously according to Zhang Yuan's explanation.

With the reverberation of one after another, the pig iron billet in the middle also had a tendency to turn from black to red.

Or the temperature of the molten iron is too high, and the melting point of the pig iron slab should be lower, otherwise this effect will never be achieved.

Seeing that half of the molten iron in the crucible had gone down like this, and the pig iron slab had been poured four times, Zhang Yuan felt that he could see if his vision could be realized.

"Stop, it's almost done, put it on the sand and wait for it to cool."

"Here."

Except for a few craftsmen who continued to work because they could not let the molten iron in the crucible solidify, the rest of the people were waiting for the iron slab to cool down, and they were also very curious about what Zhang Yuan's final purpose was.

Seeing that the iron slab was almost cooled, Zhang Yuan picked up the iron saw that had been prepared long ago, walked to the edge of the iron plate, and ordered two people to carry it to the anvil and set it up. He wanted to saw the iron by himself. Blank.

Steel is silvery white, wrought iron is close to white, and pig iron is dark gray. The iron ore here in Linqiong is smelted with gray cast iron, which is better in quality than white cast iron.

Sawing a tree requires strength, not to mention sawing a piece of iron. The iron saw in Zhang Yuan's hand is forged from pig iron and is extremely easy to break. In order not to hurt himself, Zhang Yuan was careful when sawing.

The most surface is still the color of wrought iron. Once the color changes and it is not dark gray, it is steel.

This piece of iron billet is about five centimeters thick, but it was only two centimeters originally, and the extra thickness on both sides is made by pouring wrought iron.

"Changed color."

Before sawing one centimeter down, Zhang Yuan exclaimed in exclamation, which attracted the craftsmen who were already watching to get a closer look.

"My lord, is this steel?"

Zhang Yuan nodded excitedly, which means that at least two centimeters of this billet is made of steel. rate will also increase significantly.

"Yes, the steel is out. You all have to control your mouths. These steels can allow you to live the life you want."

The craftsmen knew that Zhang Yuan was not stingy with them, so even if they betrayed this news to others, such as Zhuo Wangsun, those who are used to looking down on slaves might think that it is a great reward for these people to eat well .

The craftsmen who have monthly money naturally have a much higher vision than before. This is why Zhang Yuan pays them monthly money, and they pay so much every time.

Seeing that the steel was being tapped, Zhang Yuan was in a good mood, ordered several craftsmen to continue to do as he said before, and began to beat the iron billet on the anvil.

The steel pouring method can only reduce the complicated procedures of the steelmaking process, and there is still a long time. In order to get a real piece of steel, Zhang Yuan still has to beat it with a hammer.

Because of the system's tasks, these beatings began to have meaning.

The iron billet is really too thick, making an ax should be more labor-saving and time-saving.

Everyone saw Zhang Yuan beating the piece of iron, so they knew what the young man was going to do, so no one bothered them. The capacity of these furnaces is not large. The temperature in some furnaces should be higher. Although there is no basis for it, but with the idea of ​​excellence, Zhang Yuan asked everyone to build these two furnaces.

The molten iron in the furnace was only enough to pour the billet once, and Zhang Yuan didn't say how much to finish, so everyone had to keep working.

This is the second time for Zhang Yuan to make a utensil. Making an ax is far easier and more convenient than making an iron pot, but in order to keep the ax blade from being mixed with wrought iron and pig iron, Zhang Yuan can only beat hard , let them mix together.

As for the tempering liquid, I am not afraid of others being disgusted, anyway, it is just an axe, and Zhang Yuan used his own urine to temper it.

It takes time and effort to find urine from other animals, so Zhang Yuan did it directly.

The time quickly passed to the morning of the third day, and the ax was actually completed, but the progress bar of the system task did not jump, which made Zhang Yuan not stop working.

Could it be that the back of the ax must be made of fine steel?
Just when Zhang Yuan questioned himself, the system told him the result.

"How Steel Is Made: Reinforcement and Iron Bones: Ten Utensils (One Tenth) Are Forged from Carbon Steel Smelted by the Steel Filling Method

Mission Completion Reward: Topographic Map of Coal Mine Distribution in Shu County. "
