After the unremitting efforts of Ranbula and his people, the river tribe's fence in the industrial area by the river was built first. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

Later, starting from the construction of the iron-making plant, Wang Chuan basically went to school here.

The ironmaking workshop needs a higher room, a wider space, certain fire prevention measures, ventilation, a reasonable space layout, and even a hole in the wall to install the hydraulic blast equipment in the later stage.

Wang Chuan planned to improve the blower first and see if he could smelt molten iron with manpower blower. If it doesn't work, then improve the blast, and let the baby elephant and the little rhinoceros help drive the blower equipment and make an animal power blast. If it doesn't work, then you have to wait for the river to flow and then make a hydraulic blow.

Wang Chuan heard the old man talk about the era of steelmaking in later generations. I've heard of some small blast furnaces using manpower blasts to smelt molten steel. At that time, it was okay, and Wang Chuan felt that it was theoretically okay now. It's just that the material basis of the two eras is not the same, and everything has to be tried before you know.

For this manpower blower, Wang Chuan still chose the simplest piston type. The simpler it is, the less likely it is to make mistakes, and this is one of the most effective lessons of this era. More complex things can be designed by Wang Chuan, but people may not be able to produce them now, or they may not be able to use them after they are produced.

This time, Wang Chuan asked the wood workshop to hollow out the large-diameter golden silk nanmu. And it is a simple one-way type, in order to avoid insufficient wind, Wang Chuan prepared two blowers to be used at the same time, and the two of them staggered the blows, so that they could provide a steady stream of air. The golden silk nanmu is not easy to crack, and the piston barrel made of hollowed out is not easy to leak air, plus the two are used together, Wang Chuan feels that although such a scheme is primitive, it should be effective.

In winter, the construction progress was not fast, Wang Chuan originally planned to build a blast furnace after the plant was built, but later saw that the progress of building the house was too slow, so he simply decided to build a blast furnace while building a house.

The construction site needs to burn a fire to keep warm, and the mud needs to be used up as soon as possible, otherwise it will be hard by the wind as long as it takes half a day. If you blow it overnight, it will be as hard as a stone.

Fortunately, the bricks were burned before, and it is difficult to dry the bricks into the furnace on such a day.

Use green bricks and clay to build steps and feeding tables. In the blast furnace part, Wang Chuan also uses green bricks as the main material. However, for the bonding part, Wang Chuan used lime, worn-out pottery and a small amount of clay to grind it with a stone mill, and then calcined it in a kiln to produce a small amount of cement.

In order to prevent the furnace from collapsing, Wang Chuan built the outer wall of the blast furnace thick. Once the outer walls are built, the inner walls are first smeared with clay, and then the interior is smoothed out with the last bit of cement.

An oblique spill port is set under the bottom of the blast furnace. At the same time, the clay pipe of the air blast is connected with the angle of the chamfer. After the blast furnace was built and the blast was in place, all the joints were smeared with cement.

The blast furnace was built, and the plant was also capped.

Wang Chuan took the people in the blacksmith workshop and began to make molds.

If the molten iron passes, what kind of mold can be made of what kind of iron tools. To build a blast furnace, what Wang Chuan wanted to do most was a plow and a cauldron. Because the ploughshare is basically useless now, Wang Chuan first got the mold of the cauldron out.

Wang Chuan, the mold for making pots, has seen it in later generations. A thin little space is left between the two upside-down molds. Wait for the molten iron to be near the mold, cool it naturally, and then quench, and a pot is basically ready.

Of course, this is the scene that Wang Chuan saw others do, or in the future generations. When I sat up, I realized how difficult this thing was.

Wang Chuan used mud mixed with mud and sand to make a mold, and after the bottom layer dried, he tried many ways but did not come up with a suitable cover to cover it, leaving a cover with uniform thickness and thickness. At this time, it was Lambra who came up with a solution. He cut out the shape of a cauldron out of soft wood, then buckled directly to the clay fan underneath, and then covered it with clay to knead the lid. After the lid is dried, remove the lid and remove the wooden pot, and the mold for a pot is ready.

This method worked, and Wang Chuan made ten cauldrons of mud in one go.

In addition to the clay fan of the pot, Wang Chuan also got some clay fan such as knives, axes, hammers and hoes as samples.

On this day, when the roof was built, it snowed again. Wang Chuan stopped the class and came to direct the first furnace of the trial. This time, in order to ensure victory, the material thrown in was sponge iron burned in a pit.

As baskets of charcoal were poured into the blast furnace from the feeding table, Bihu and Bark personally pulled up the blast, and the flames erupting from the blast furnace almost lifted the roof of more than ten meters. The scorching heat swept the wind and snow outside, making the people in the house eager to take off their clothes.

The leaders of the tribe stood at the other end of the factory and watched, all of them in horror. The fire in the blacksmith used to rise only one meter. This fire is ten meters tall when it stretches out, and it is really a fire dragon. Why is Elder Chuan so powerful, can he get this out? Is it possible to turn around and make a fire dragon that is tens of meters away?

Bihu and Barka were sweating, Wang Chuan stood more than ten meters away from the blast furnace, secretly estimating the time, and at the same time looking at the situation of the blast furnace body, as soon as there was any crack, everyone would be evacuated immediately. The situation of blast furnace collapse in later generations has not happened, and it is really hard to say whether there is such a risk as something that I got out of my house halfway.

The time was almost up, and Wang Chuan ordered to stop the air blast and open the outlet. The outlet made of ceramic slabs and stone slabs was opened, and a stream of hot red iron flowed from the blast furnace.

Bihu took the long-handled crucible, scooped out a tube of molten iron from the material mouth, came to the mud fan of the cauldron, and poured it gently.

Bihu then handed the cauldron to the bark, which was also spooned through molten iron and poured a cauldron. After pouring it in this way, basically every centurion experienced it.

Wang Chuan and Zhuangniu worked together to lift the mud fan of the first pot poured by Bihu, and found that the pot inside was smooth and clean, and there was little trachoma. After clamping it with a clamp and quenching it with a damp cloth dipped in water, it was clamped in front of the onlookers at the door. Everyone was amazed.

Wang Chuan said: "The dishes cooked by this thing are extremely delicious, today I will cook a meal and cook it in ten pots, so that everyone can taste it!" ”

Everyone has heard of the good things cooked by Wang Chuan, but now there are not many people who have eaten them, and everyone applauded when they stopped.

Kuan is more concerned with the pouring of other utensils other than the cauldron. He took the clip and took out a machete directly from the clay fan, quenched it, clamped it to the desk next to it, and beat it with a hammer. He has been striking iron for a long time, and he can tell from the sound that the material is good or bad. After beating for a while, he ignored the fact that the blade was still hot, grabbed the part that tied the handle through a layer of cloth, and cut it down on the desk.

The blade of the knife entered the wood, but there was no collapse, and Kuan couldn't help crying loudly when he saw it.
