A new conspiracy has begun again, and Wang Kang naturally doesn't know.

After the "Mountain God" incident, all parties have become more motivated, and Wang Kang is also very generous in food.

With high-intensity daily work, it is not enough to keep up with food. Therefore, Wang Kang also hired women in the city and cooked on the construction site.

Xinfeng County itself is barren and lacks food. The food brought by Wang Kang is obviously unable to supply such a large demand. What should I do?

At this time, the good relationship established by Wang Kang and Jinyu Chamber of Commerce played a role, and a large amount of meat and vegetables were transported here.

Not only that, the equipment, wood, etc. required for construction site construction are also purchased from Jinyu Chamber of Commerce.

Moreover, in order to facilitate transportation, the Jinyu Chamber of Commerce also invested to level the Erdaogou Road leading to Xinfeng County from Yangzhou City.

Because Wang Kang is now the largest customer of their Jinyu Chamber of Commerce.

In the past few days, with the addition of Li Zheng and others, the first set of floor furnace equipment was finally built.

As the name suggests, the ground furnace was built underground. Wang Kang walked down and was a huge excavated space, where two tall ground furnaces were built.

Each floor furnace is nearly three meters high and has a diameter of nearly two meters. This scale can be said to be quite large.

There are platform stairs on both sides of the floor furnace, which can go straight to the top, and there is a sealed circular passage from the bottom to directly connect the next floor furnace.

This is the fruit of labor for several consecutive days. It looks like two huge cylindrical barrels on the outside, but in fact there is another world inside.

The inner and outer walls of the floor furnace are built with refractory bricks and are enclosed with high alumina bauxite mixed clay, which makes the floor furnace completely sealed and makes it difficult to dissipate heat.

There are two blowers on both sides of the floor furnace. They are called blowers, but in fact they are advanced versions of the bellows. It’s just that Wang Kang called it.

It is smaller than a bellows. There is actually no difference just looking at the outside, but the structure inside is very complex. The biggest difference is that this blower is not a hand-pulled type, but a foot-mounted type.

This design can save a lot of effort and improve efficiency than hand-pulling.

And its wind power and sustainability are much larger than traditional bellows.

This is the biggest improvement. We must know that people used the most primitive bellows in this era. The wind-loading technology is backward, which requires a lot of manpower to accumulate.

It takes a long time to refine a furnace of iron, and it is also very tiring...

When Wang Kang walked down, several craftsmen were already starting to prepare.

They laid charcoal in the floor furnace, and the charcoal was neatly placed iron ore, which filled the entire floor furnace.

Since the floor furnace designed by Wang Kang is built layer by layer inside and there are gaps between each layer, ventilation is not a problem at all.

The preparations are completed and the ignition is about to start, which is very simple, because there is a special ignition port under this new floor furnace.

"This design is useful." Li Zheng, who was watching from the side, nodded and praised.

After several contacts, they also participated in the construction of the floor furnace. Although they did not think that Wang Kang could smel something harder than iron, they did not despise it as before.

Because some parts of this floor furnace are indeed worth learning from, especially the various structures in the furnace, which are much more complicated than conventional floor furnaces.

There are some places that they can't understand.

It was seen that the fire in the furnace had already started, and the craftsmen on both sides had already started to step on the blower and pour the air into the floor furnace one by one.

The blower's opening is a cylinder made of animal skin, which is directly connected to the air inlet of the floor furnace, so as to ensure the maximum utilization of wind power.

"Master Kang, is this the new bellows you made? This foot-pedaling style is a good invention, and it doesn't take any effort to see when they use it." Master Xi asked from the side.

"Well," Wang Kang nodded and replied. The bellows are complicated, and the transmission parts are equipped with gears, which are made of wooden.

When used, there will definitely be wear and tear, and the life span is very short. After using it for a while, it will need to be replaced, but this is also impossible.

With the current conditions, there is definitely no way to make iron gears.

Wang Fuchen asked, "Young Master Kang, are you really sure to dissolve iron into iron?"

This is a big difficulty when smelting iron. The melt temperature of pure iron must reach at least 1,500 degrees, which is difficult to achieve.

For example, when smelting iron in the Metallurgical Bureau, the iron ore is basically burned into pig iron and then continued to forge, and sometimes liquid will appear.

Because pig iron only needs a temperature of 1,200 degrees to be able to be solution.

However, Wang Kang wanted to directly refine iron ore into iron, which is what they didn't believe.

"Just watch it."

Wang Kang smiled and did not explain much. There was no specific temperature data in ancient times. Everything was exploring experience. I'm afraid they would be difficult for them to understand the explanation.

"Then let's wait and see!" Li Zheng said, and then the eyes of several people looked at the ground stove.

With the infusion of wind, the charcoal in the floor furnace began to burn rapidly and the firepower became stronger and stronger. Of course, this is invisible.

But the temperature can be felt, although it is a refractory brick insulating the floor furnace, most of the heat temperature is felt.

But the high temperature in this space still makes people feel like they are about to be burnt, and the heat waves are coming.

"Why is this temperature so high?"

Li Zheng said in surprise, now that the outside of the stove feels like this, so what should be done inside?

Wang Kang smiled lightly and didn't say anything, because it was not only charcoal but also coke in the stove, which was an additional harvest found when digging iron ore.

Coke is the main raw material in modern iron smelting and steelmaking. It is more suitable than earth charcoal and can reach higher temperatures.

Although it felt so hot, Wang Kang also had excitement in his eyes, because this was hosted by him, and in this era, a milestone progress.

The progress is still continuing, and the craftsmen who blow the wind have changed. They are naked and all have a big body, and they take turns to replace them.

"Master Kang, the temperature here is too high. Do you want to go out and wait first?" At this time, a craftsman who was promoted to foreman came over and asked.

"It's okay, I'm just waiting here." Wang Kang said, with him, these craftsmen are more motivated, and he also wants to witness the emergence of steel with his own eyes.

The temperature was getting higher and higher, like a big steamer, Li Zheng looked at Wang Kang in surprise.

Didn’t he say he was just a rich young master? How could he still withstand such an environment?

In the past few days, they also specifically inquired about Wang Kang. When they knew Wang Kang's reputation, they became more and more prodigal. No wonder they agreed without blinking their eyes...

It is because of this that they are confused. Wang Kang's performances are not like prodigal sons at all.

At this moment, even the few of them took off their coats. They were so old that Wang Kang's forehead was covered with sweat, but he did not move at all, and his perseverance was surprising.

Waiting was boring, and another hour passed (note, an hour in ancient times was two hours.) The diameter of the pipe extending from the stove finally had a hot iron flowing out...

this?

Seeing this scene, Li Zheng and others could no longer remain calm...
Chapter completed!
