The iron ore stock that Liu Shan informed is huge, and it will not affect some of them.

"Besides, my side is short of manpower, and the Ministry of Industry needs to send skilled craftsmen to mine? What do you think?"

"It should be so!" Wang Fuchen responded.

"In addition, we must choose reliable people to dispatch craftsmen," Wang Kang said after a pause, "I don't want outsiders to know too much information about my iron mines."

"understand."

This is easy to understand.

"Since this is the case, then there will be three Laos next. I have a lot of things to deal with..."

Wang Kang said again: "Because I need a lot of steel for road construction this time, I only built a set of furnaces, and I will build another one next time!"

"I intend to turn this place into an industrial park in Xinfeng County to mass-produce steel!"

"Industrial park?" Li Zheng was puzzled, this was the first time he heard this word.

"Yes, it's the industrial park!" Wang Kang said with a smile.

This is also his plan. This area has already started construction everywhere, including brick kilns, cement firing, and iron and steel smelting.

These are currently being prepared for road construction, but what about when the road construction is completed?These constructions in the city are indispensable.

Moreover, refractory bricks, cement, and even steel are all products of a cross-age era and can be sold in the future.

Therefore, this area will be retained after the construction is completed, and will be the industrial park of Xinfeng County.

"By the way, I can't tell you the core of iron smelting technology, I hope you can understand." Wang Kang said again.

This is very important. Unique things such as steel smelting technology should be in their own hands, and outsiders should never be allowed to infect them.

This is the case with gunpowder, even if it is the court, he treats everyone the same.

Although they have witnessed the whole process just now, and even participated in it, it is not like this that they have mastered it.

The real core, such as the raw materials used in refining, the ratio of iron powder, and the mastery of time, may fail if it is missing a little.

These Wang Kang had already informed him of the craftsmen he had accepted, and after his screening, they were all faithful and reliable.

Everyone also knows one, which is safer.

"Understood!" Several people nodded without hesitation. This is Wang Kang's unique invention, and it is such an important technology, how could it be leaked?

Not a fool.

"Haha!" After everything was settled, Wang Kang smiled and said, "It's hot and cold here underground, let's go up first!"

Hearing this, several people were startled again, this is also the reason why they admire Wang Kang.

The refining of the second furnace started here again. When Wang Kang went up, the three of them were also discussing the division of labor, and finally decided that Li Zheng would be in charge of the new furnace.

Master Xi is responsible for the inspection of the smelted steel, which is also very important, because the smelting is all manual, and if there is any mistake, it will fail.

The inspection link is essential, otherwise there will be quality problems, and the final use will be fatal.

And Wang Fuchen is in charge of coordinating.

The division of labor between the three is clear, and Wang Kang is also very satisfied. In this way, a scale will be formed and mass production of steel products will be realized.

After finishing here, Wang Kang didn't have time to wash and change clothes, so he came to the cement production place next to this.

Compared with smelting steel, the firing of cement is relatively simple. The main raw materials such as limestone and clay are ready-made, and only need to be fired.

Wang Kang arranged a special isolation enclosure to divide it from other areas, and he also distributed simple masks to the craftsmen to prevent dust.

Because the production is simple, a lot of cement has been produced in a few days and piled up into pieces.

Now that steel has been produced, it can be supported by concrete in the tunnel.

According to Wang Kang's vision, this step is carried out at the same time, and the support and excavation will not affect it, and the progress is very fast now, and it is being extended every day.

The combination of the two can improve efficiency.

But there is one thing that is more troublesome.

Concrete is actually made of cement as a gel material, sand and stone as aggregates, mixed with water in a certain proportion, stirred, formed, and cured.

This is the most common and easiest to make, also known as ordinary concrete.

But there is a difficulty in this, stirring and pouring.

In modern times, this is all done with special machines, such as mixers, conveyor vehicles, etc. This is particularly important. If there is a slight error, the uniformity of the concrete will be difficult to maintain, and stratification and segregation will occur.

In order to avoid this, Wang Kang decided to make concrete directly in the tunnel construction, and cows, horses, etc. can be used instead for mixing.

As for perfusion, it can only be done manually.

Wang Kang made arrangements here, and ordered the craftsmen to deliver the ingredients first and do the preparation work. When everything was complete, he began to make reinforced concrete to support the tunnel...

[Author's digression]: Today is still [-] words, please vote!In addition, the construction is in full swing and good ideas are collected.

Chapter 223 I am me!

Another few days passed, and the first batch of steel produced by the No. [-] furnace named by Wang Kang was ready for use after being inspected and cooled.

The whole body is slender and exudes a perfect metallic luster, neatly piled up, and under the guidance of Wang Fuchen, the soil model has been further improved.

As a result, the overall specifications of the refined steel products are also close to uniform, and Wang Kang feels a sense of accomplishment in his heart when he looks at it.

Its hardness characteristics are definitely not comparable to the previous life, but it is already used to meet the needs.

This is a cross-generational production!

"Load and deliver!" Wang Kang shouted.

Immediately, workers began to lift and load it onto the carriage. Everything was ready, and the first reinforced concrete support will be made today!

Several horse-drawn carriages transported it to the entrance of the tunnel, where materials were also piled up, including sand, stone, and cement.

It's time to mix the concrete.

In order to mix them evenly, Wang Kang asked someone to build a large circular pool. The bottom and inner walls of the circular pool were smoothed with cement and smooth.

In the middle of the round pool is something similar to a millstone, except that two large blades extend from it, and these two blades are made of iron.

The whole round pool looks very much like the clarified pool of the factory in the previous life, which is used for mixing materials.
