Chapter 80 Ironmaking 4
"No, increase the temperature again!" Zhang Yang said loudly.
After such a long time, the flame inis still orange-red. Obviously, the furnace temperature is still not high enough.
Hearing Zhang Yang's anxious shouting, several people who shook the bellows increased their strength and accelerated the speed of pulling the bellows.
However, the flame is still the same, and it hasn't changed much.
What should I do? In this stove is Zhang Yang's painstaking efforts. If this doesn't work, the refined ones are all waste. Although iron ore is free, this coke is all black silver!
"Increase the furnace temperature!" Zhang Yang continued.
But several people who shook the bellows had slowed down. The high-intensity labor just now almost exhausted them.
"Brother, I'm afraid it won't work just like this." Li Bosheng said. We have to think of something else."
"Nonsense, I need to know that there are other ways, which have been used for a long time." Zhang Yang said helplessly. Suddenly, he remembered a thing of the past.
When I was in high school, I often ate in a small restaurant outside. At that time, the price of vegetables was very cheap. A large plate of scrambled eggs with tomatoes only cost two yuan. The conditions of the small restaurant are very simple. There is only a curtain hanging in the kitchen and outside, swaying in the wind. When eating out, you can often see the figure of the chef inside. The skillful technique and the extremely free work made Zhang Yang's greatest dream at that time was to go to a chef school.
After observing more times, Zhang Yang found that the chef had a characteristic. From time to time, he put a spoonful of oil in a large spoon and sprinkled it on the stove. Every time he sprinkled it, the flames roared so high.
Later, when it was ripe, Zhang Yang asked the chef why he poured oil on the fire. The master explained simply: In order to increase the temperature, when cooking, you need to control the heat. Sometimes, the stove is not strong, sprinkle a little oil, and the fire will be strong, or sprinkle some coal powder, but the dish will also fly into the coal powder. I can't eat it, so I have to use oil to increase the temperature.
That's a waste! Zhang Yang had this idea at that time. Later, he remembered that he should not have gutter oil at that time, which promotes the traditional virtues of diligence and thrift of the Chinese nation, right?
If the furnace temperature is not enough, you can add some more fuel. In this era, oil is very precious. In a large pot of vegetables, there is only one oil flower. However, coal is still available, and coke is more effective than coal.
"Quick, crush those coke pieces into powder for me, right now!" Zhang Yang ordered.
Do you want to grind it into powder again? Everyone has been tired of this work these days. However, just complaining in their hearts, several people immediately picked up the sledgehammer, smashed them into small pieces first, and then pounded them into pieces.
"Hurry up, hurry up." Zhang Yang kept urging.
Looking at some powders that had just been ground, Zhang Yang couldn't wait to hold a handful in his hand and came to the bellows.
When several people pulled the bellows together, the air inlet in the bellows was opened. Zhang Yang took this opportunity to put the coke powder in his hand into the air inlet.
The bellows are so huge that the air inlet is naturally very large, about the size of Zhang Yang's head. It is more than enough to reach into one hand.
Under the suction of the wind, the powder in the hand immediately flew clean and was all inhaled into the bellows.
Several people have pulled the bellows to the end. Before closing the bellows, Zhang Yang took his hand back in time.
"Huo." The air inlet of the bellows was closed, and the air outlet was opened. With the end of coke and Zhang Yang's hope, the strong wind flew into the blast furnace.
"Wow!" Sure enough, the flame suddenly became much more prosperous than just now, and it also turned into a golden orange!
"Good! That's it, come on!" Zhang Yang said.
Li Bosheng also picked up a handful, learning from Zhang Yang's appearance, and preparing to put the powder into the air outlet.
"Shoop coke powder with a shovel, don't use your hands!" Zhang Yang reminded.
Just now, I was just doing an experiment by myself, so I took a risk. However, if I had to put it in with my hand every time, it was too dangerous. When such a big bellows were pushed, the wind inside would close the air inlet. Its strength was very strong. One was inadverted and his hand was not taken out in time. Maybe it would be entered. The wooden board of the air outlet was broken.
When producing, 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 coke powder into it with the rhythm of the bellows.
Zhang Yang looked at the flames inside and smiled.
The lake is printed with the afterglow of the sunset, calm and peaceful, like a huge mirror, dressed in a touch of rouge. The fishing boat sings late and ripples at the beginning of the lake. The sunset gradually faded, and the sky and the earth turned silvery white. The surroundings gradually faded, and the victory lake became silent, and only the frogs were still screaming tirelessly on the lotus leaves.
Tireless, in addition to frogs, there are also people on the island hidden in the reeds.
Not only Zhang Yang and Li Bosheng, but also Shide and others ran to the north to watch ironmaking after finishing their work.
This is really an exciting moment. Zhang Yang looked at the golden orange flame in the blast furnace gradually dimming, and finally gave instructions: "Open the furnace and release the iron water!"
Li Bosheng used a long bamboo pole from afar to open the iron outlet under the blast furnace.
The fiery red iron water flowed out and poured into the pre-prepared mud mold. After the temperature cooled down, it became pieces of steel ingots.
The surroundings are also red with the iron water.
"Awesome, it has become iron water!"
"That's right, big brother is really a god! These stones were put inside, and when they were lit, they turned into molten iron!"
"Look at that color, it's like a fire dragon!" Everyone was talking about it.
Watching the iron flowing out, Zhang Yang not only did not relax, but was even more nervous.
When the iron water cools down, can the steel ingot meet your own needs?
The iron water gradually decreased, the flow became slower and slower, and finally stopped flowing.
Zhang Yang looked around, and there were about 20 slots in total, each of which was about one stone. These 20 slots were almost 2,000 catties.
The efficiency of this blast furnace for making iron is much higher than that of those ordinary stoves. If only two thousand catties of iron can be made into a fire, a fire can also be made of five catties of iron, which is enough to make four hundred fire. What a spectacular scene will be! When the iron water gradually cooled down, Zhang Yang's fiery heart also cooled down.
Why is this different from the steel ingot you use?
The color is dark, just like withered yellow leaves, and the texture is also very poor. The carbon, sulfur and phosphorus content inside seriously exceed the standard. There is no doubt that this ironmaking failed.
This kind of iron is hard and brittle. It must be the result of the explosion. Otherwise, the barrel will have to be made very thick, and it will lose the convenient surname of the rifle.
Zhang Yang's face was full of disappointment, but everyone cheered.
"Good 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 to the east cabin.
Everyone was stunned. What's wrong with the eldest brother?
