Chapter 80 Iron Smelting (IV)

"No, increase the temperature!" Zhang Yang said loudly.

The flames inside have been in such a long time, and they are still orange-red, and the furnace temperature is obviously not high enough.

Hearing Zhang Yang's anxious shouts, the few people shaking the bellows increased their strength and accelerated the speed of pulling the bellows.

However, the flames were still the same, and there was no big change.

What should I do? Zhang Yang's efforts in this stove are Zhang Yang's efforts. If this cannot be successful, then the refined ones will be scrap. Although iron ore is worthless, the coke is all black silver!

"Increase the furnace temperature!" Zhang Yang continued.

But the few people who were shaking the bellows had slowed down, and the high-intensity labor just now almost exhausted them.

"Brother, I'm afraid this won't work." Li Bosheng said. "You have to think of some other solutions."

"Nonsense, I have to know there are other ways, I have used it a long time ago." Zhang Yang said helplessly. Suddenly, he remembered a past event.

When I was in high school, I often ate in a small restaurant outside. The price of vegetables was very cheap at that time. A large plate of fried eggs with tomatoes only cost two yuan. The conditions in the small restaurant were very simple. There was only a curtain hanging in the kitchen and outside, swaying in the wind. When I was eating outside, I often saw the figure of the cooking chef inside. The skillful technique and the extremely comfortable kung fu made Zhang Yang’s biggest ideal at that time was to go to a chef’s school.

After observing more often, Zhang Yang found that the chef had a characteristic. From time to time, he used a large spoon of oil and sprinkled it on the stove. Every time he sprinkled, the flames would rush up very high.

Later, when it got mixed up, Zhang Yang asked the chef why he poured oil on the fire. The master explained simply: In order to increase the temperature, you need to master the heat when cooking. Sometimes, if the stove is not strong, sprinkle some oil and the fire will be strong. Or, sprinkle some coal powder, but then the vegetables will fly into the pulverized dish and you can't eat it, so you have to use oil to increase the temperature.

That's a waste! Zhang Yang had this idea at that time, and later he remembered that he probably didn't have gutter oil, such as fountain oil, that promoted the traditional virtues of thrift and thrift in the Chinese nation, at that time?

If the furnace temperature is not enough, some fuel can be added. In this era, oil was very precious, and there was only one oil flower in a large pot of vegetables. However, coal can still be found, and coke is more effective than coal.

"Hurry, grind the pieces of coke into powder for me, right away!" Zhang Yang ordered.

Are you going to grind it into powder again? Everyone has been tired of this work these days. But just complaining in their hearts, a few people immediately picked up the sledgehammers, smashed them into small pieces, and then smashed them into pieces.

"Hurry up, hurry up." Zhang Yang kept urging.

Looking at some of the powder just crushed, Zhang Yang couldn't wait to hold it in his hand and come to the bellows.

When several people worked together to pull the bellows, the air inlet in the bellows was opened immediately. Zhang Yang took this opportunity to put the handful of coke powder in his hand into the air inlet.

The bellows are so huge that the air inlet is naturally very large, about the same size as Zhang Yang's head, and it is more than enough to reach into one hand.

Under the suction of the wind, the powder in his hand immediately flew cleanly and was sucked into the bellows.

Several people had already pulled the bellows to their heads. Before closing the air inlet, Zhang Yang took his hand back in time.

"Huda." The air inlet of the bellows was closed, the air outlet was opened, with coke powder and Zhang Yang's hope, the strong wind flew into the blast furnace.

"Huh!" Sure enough, the flames were much stronger than before, and they also turned into kumquat!

"Okay! That's it, let's go again!" Zhang Yang said.

Li Bosheng also held a handful of it, imitating Zhang Yang's appearance, and prepared to put the powder into the air inlet.

"Shut the coke powder with a shovel, stop using your hands!" Zhang Yang reminded.

I was just doing the experiment myself just now, so I took a risk. However, it would be too dangerous to reach in with my hands every time. For such a large bellows, when pushing the bellows, the wind inside closed the air inlet. The force was very strong. If you were not careful and didn't take out your hand in time, you might be interrupted by the wooden boards at the air inlet.

During production, you must pay attention to safety and prevent production accidents.

When Li Bosheng heard Zhang Yang's reminder, he immediately understood. He picked up a small shovel next to him and put the coke powder into it with one shovel at the rhythm of the bellows.

Zhang Yang looked at the flames inside and smiled on his face.

The lake is printed with the afterglow of the sunset, calm and peaceful, like a huge mirror, made up of a touch of rouge, and the fishing boat sang in the evening, causing ripples on the lake. The sunset gradually faded, and the world turned silvery white. The surroundings gradually faded, and the Desheng Lake became silent, and only the frogs were still screaming tirelessly on the lotus leaves.

Tired, besides the frogs, there are also the crowds of people hidden in the island among the reeds.

Not only Zhang Yang and Li Bosheng, but even Shide and others ran to the north to see the iron smelting after finishing their work.

This was really an exciting moment. Zhang Yang watched the golden orange flames in the blast furnace gradually dimming, and finally gave an instruction: "Open the furnace and put molten iron!"

Li Bosheng used a long bamboo pole to open the iron outlet under the blast furnace from a distance.

The fiery red molten iron flowed out and poured into the mud mold prepared in advance. After the temperature dropped, it turned into pieces of steel ingots.

The iron is also illuminated red by the iron.

"Awesome, it's really a molten iron!"

"That's right, brother is really a magical one! These stones are placed inside and ignite them, and they become molten iron!"

"Looking at that color, it's like a fire dragon!" Everyone was talking.

Seeing the molten iron flowing out, Zhang Yang not only did not relax, but instead became even more nervous.

When the iron is cooled down, can the steel ingot meet your needs?

The iron gradually became less and the flow became slower and slower, and finally stopped flowing.

Zhang Yang looked around and found that there were about twenty troughs flowing, each trough was about one stone. These twenty troughs were almost two thousand kilograms.

The efficiency of this blast furnace is much higher than that of ordinary furnaces. If only these two thousand kilograms of iron can be made into a musket, a musket can use five kilograms of iron, and it can make four hundred muskets. What a spectacular scene that these 400 muskets will be fired in a strait! When the iron gradually cooled down, Zhang Yang's hot heart also cooled down.

Why is this different from the steel ingot you use?

The color is dull, like yellow leaves, and the texture is also very poor. The charcoal, sulfur and phosphorus content inside are seriously exceeding the standard. There is no doubt that the iron smelting failed this time.

This kind of iron is hard and brittle. The barrel used as a musket is definitely the result of a blow-off. Otherwise, the barrel will have to be made very thick, which will lose the convenience of carrying the rifle.

Zhang Yang looked disappointed, but everyone cheered.

"What a iron, I've never seen so many good irons!"

"Is this iron okay? What a bird!" Zhang Yang was so angry that he turned his head and walked towards the cabin to the east.
