Wang Kang's intention was not a sudden rush of blood, but a careful consideration.

Li Zheng and the other three craftsmen were appreciated by him. Secondly, he wanted to have a good relationship with the metallurgy bureau. Furthermore, he wanted to have a good relationship with the Ministry of industry and the imperial court!

Previously, Wang Kang knew that under the control of the old aristocrats and the control of resources, even the Metallurgical Industry Bureau needed to buy from them and be controlled by them. How difficult was this?

the count of Fuyang is now a pioneer in fighting against the old aristocrats, but by itself it is far from enough. The old aristocrats are very powerful. Like now, there is an earl of Yongding jumping out.

Therefore, Wang Kang needs allies, and the construction of his Xinfeng County is uncertain. Just like today, he needs the help of the Ministry of industry, so it is necessary to have a good relationship.

This is also for his preparation for going to Kyoto. Wang Kang has a hunch that Kyoto will be the main battlefield for him to fight against the old aristocrats in the future

Since we want to have a good relationship, fortunately, we can do a good job in the end. Isn't your Metallurgical Bureau short of iron ore? Then I won't give you money, I will give you iron ore directly!

"Master Kang, it's impossible..." Wang Fu Chen is very busy. If he said that before, he had a gambling contract, he can also mention it.

Now that Wang Kang has refined steel, it is tantamount to overturning all their previous conclusions. How is it appropriate to ask for other people's things?

"Yes

"We're not unreasonable people. We don't get paid for our work. We've come here to serve our orders..."

He waved his hand and said, "you don't have to say much. It's settled."

"Don't refuse. It's my contribution to the smelting Bureau and the imperial court."

Several people looked at each other speechless. Considering the current difficulties of the Metallurgical Industry Bureau, Wang Fu Chen sighed for a long time, "Master Kang returns good for evil, and knows the truth. In this case, we will not refuse!"

After that, they bowed to Wang Kangli and said, "although we can't compare with Master Kang in iron smelting, we are experienced. We will do our best here!"

"Ha ha!"

Seeing this, Wang Kang held up the three and said with a smile, "but I said in advance that iron ore can't be delivered now, and I have to wait for the completion of the project on my side."

Liushan told us that there was a huge stock of iron ore, which had no effect on some of them.

"Besides, I'm short of manpower, so the mining department needs to send skilled craftsmen? What do you think? "

"So be it!" Wang Fuchen responded.

"In addition to dispatching craftsmen, we have to choose reliable people," Wang said with a pause. "I don't want outsiders to know too much about me."

"Yes, yes."

This is easy to understand.

"If that's the case, then thank you three. I have a lot to deal with..."

Wang Kang said: "because I need a lot of steel for road construction this time, now I just built a set of furnace, and then I will build a new one again!"

"I intend to build this place into an industrial park in Xinfeng County, and mass produce steel products!"

"Industrial park?" Li Zheng is puzzled, this word is heard for the first time.

"Yes, industrial park!" Wang Kang said with a smile.

This is also his plan. Now this area has been started everywhere. There are brick kilns, cement burning, iron smelting and steel making.

At present, these are all preparations for road construction, but when the road construction is completed? These constructions in the city are indispensable.

What's more, refractory bricks, cement and even steel are all cross era products, which can be sold in the future.

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

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

This is very important, such as steel smelting technology is a unique thing or to master in their own hands, never allow outsiders.

Gunpowder is like this, even if it is the imperial court, he also regarded the same people.

Although they have just witnessed the whole process and even participated in it, they are not able to grasp it.

The real core, such as the raw materials used in refining, the proportion of iron powder, and the mastery of time, may fail without a little.

Wang Kang has told the craftsmen he has received, and after his screening, these people are loyal and reliable.

Everyone knows one of them. It's safer.

"Understand Without hesitation, several people nodded. This is Wang Kang's unique invention and such an important technology. How could it be disclosed?

It's not stupid.

"Ha ha!" When everything was settled, Wang Kang said with a smile: "it's hot and cold in the underground. Let's go up first!"

Smell speech, a few people are one Zheng again, this also is the reason that they admire Wang Kang.

Here, the second furnace was refined again. Wang Kang went up, and the three were discussing the division of labor. Finally, Li Zheng decided to be responsible for the construction of the furnace.

Master Xi is responsible for the inspection of steel smelting, which is also very important, because refining is manual, and any mistakes will fail.The link of inspection is essential, otherwise there are quality problems, the final use will be fatal.

Wang Fuchen is responsible for overall planning.

Wang Kang is also satisfied with the clear division of labor among the three. In this way, the scale will be formed and the mass production of steel will be realized.

At the end of the day, Wang Kang didn't have time to clean and change his clothes. He came to the place where the cement was produced.

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 circle here, which was divided into other areas, and he also issued simple masks to the craftsmen to prevent dust.

Because of the simple production, a lot of cement has been produced for several days and piled up into pieces.

Now that steel products have been produced, supporting concrete can be used in the deep road.

According to Wang Kang's assumption, this step is carried out at the same time, and the support and excavation do not affect it. Moreover, the progress is very fast now, extending every day.

The combination of the two can improve the efficiency.

But one thing is more troublesome.

concrete is actually used cement as gel material, sand, stone as aggregate, and water to a certain proportion of coordination, mixing, molding, maintenance of cement concrete.

This is the most common and easy to do, also called ordinary concrete.

But one of the difficulties is mixing and pouring.

In modern times, this is done by special machines, such as mixers and delivery trucks. This is particularly important. If there is a slight error, the uniformity of concrete is difficult to maintain, and the phenomenon of stratification and segregation will appear.

In order to avoid this problem, Wang Kang decided to directly construct the tunnel. Now he can make concrete. If mixing, he can use cattle and horses instead.

As for perfusion, we can only use manpower.

Wang Kang made arrangements here. He ordered the craftsmen to mix and transport the materials first and do the preparatory work. When everything was ready, he began to make reinforced concrete and support the tunnel
