Chapter 98 (2/2)

It's hard to stay in the cowshed, but it's better than not finding any grass after the heavy snow. At least those two legged monsters here have prepared a lot of wild grass. No matter how heavy the snow is, it won't affect these cattle demons to eat.

As soon as he went out, the stone bear, who was shocked by the heavy snow, was as excited as a child. In his hand, he played the guitar and took the microphone. He shook his body, opened his mouth, howled and sang a song ”let me spread a little wild on the snow”. Then, under the eyes of a group of people, he was watching, With a wave of his big hand, he said in a loud voice, ”let's go and make steel together.”

No matter how heavy the snow is, it can't resist the enthusiasm of the people, so the earth blast furnace standing in the open space in the center of the tribe is burning again.

The hot air made it impossible for snowflakes to fall in the area tens of meters above the blast furnace, and the big snowflakes could not resist the heat from the blast furnace.

At last, there are sheds on the square pond where the molten iron is stored, but in fact, even without those sheds, the heat emitted by the molten iron is enough to keep the snowflakes from falling.

In such cold weather, the people who are responsible for mixing molten iron are even working barehanded. It's too hot by fangtang!

In order to increase the contact area between molten iron and oxygen, the stone bear commanded the people to build another square pond long before the second furnace was opened. With two ponds for molten iron, the depth of molten iron is reduced by half, and it is much easier to stir.

This time, the stone bear must let the clan fully stir the molten iron, so as to make the decarbonization of molten iron more thorough.

Of course, the thin iron plates made by the blacksmiths are also bound with some pig iron sheets early, and then put into the pond together as decarbonizing agent.

In this steelmaking, the stone bear has to operate according to the real steel pouring method.

The yellow and white molten iron is stirred by many clansmen in the two ponds. Although it is very difficult to stir up the sticky molten iron, it can't stand the enthusiasm of the clansmen. These extremely heavy molten iron are almost stirred up in front of a group of clansmen working in the relay

And the cooked iron plates that had been put into the pond were about to melt. The melting point of cooked iron is much lower than that of pig iron. Once the cooked iron melts, the carbon content in molten iron will be further reduced.

The wood planer with two clansmen nervously records the weight and proportion of all the materials added in this steelmaking, which is of great value for the next steelmaking.

If the steelmaking is successful this time, the materials can be put in according to this proportion in the next steelmaking. If it is not successful, we should improve on the basis of these data, and sooner or later we can produce qualified steel.

Although the temperature of hot metal flowing out of the blast furnace is extremely high, the law of natural cooling can not be upheld.

So, when the hot metal is almost stirred, the wood planer gives an order, and the people who have been prepared for a long time take the big iron spoon or the clay spoon made of kaolin to ladle the thick hot metal into the mold that has been heated for a long time.

At this stage, everyone is happy, because they all know that at this stage, regardless of the quality of steel, a large number of iron will be added to the tribe
