"Ha ha!"

"Listen to what you said just now, I thought you were knowledgeable, but now it seems that you are still ignorant!"

"Speak up!"

Several people are laughing, even the original recruitment of craftsmen, are surprised to see Wang Kang.

Something harder than iron?

It is true, but it is not easy to refine.

And what's steel? I've never heard of it.

"It's good for you to have this idea, but don't be paranoid," Li Zheng said with a disdainful smile

Master Xi is a master of cast iron in the Metallurgical Industry Bureau, and he purifies the iron embryo. In this respect, he has the most say.

After hearing this, master Xi said with a smile, "if you want to dissolve and refine a metal that is harder than iron, in fact, our metallurgy bureau has already started to study it!"

"It has been shown many times that the higher the temperature of ironmaking, the harder the material of iron will be

After hearing these words, Wang Kang nodded. It seems that the metallurgical industry bureau is not good for nothing. It is not easy to find this point.

At this time, master Xi continued: "the solution of iron is charcoal. The temperature of charcoal is limited. This is a difficult point that can not be broken through at all."

"I have purified iron embryo before. Do you know how to do it? Melting, hammering and so on make the hardness of iron increase

"But this kind of method requires a lot of manpower. You mean you want to use it in a large amount. With respect, I can't do it at all."

Li Zheng said with a sneer, "we have come to listen to the order of Lord Shangshu, but we find that you don't adopt our method at all. In this case, we have to go back!"

"Yes, I've been immersed in things that I haven't done for half a generation. What can you understand as a rich young master?"

"If it's just hearsay, we'll talk nonsense and say we're ignorant? How ridiculous

Several people echoed, and even the craftsmen who were in charge of them were also sarcastic.

It's a joke for a rich young master to make something harder than iron.

"All masters, stay here. How can you leave easily if you come here not far away?" Xu Changlin is busy.

These people were invited by Wang Dingchang from the metallurgy bureau. If they went back, it would be a waste of effort.

What's more, it's because of Wang Kang. If it's spread to the imperial court in Kyoto, the Earl's residence will be dark!

"Master Kang, just listen to some masters!" Xu Changlin tried to persuade him.

Although the young master has changed a lot now, he has developed a formula for dyeing purple cloth before, which has made Fuyang cloth shop famous and its profit has doubled.

But iron smelting and cloth dyeing are two extremes!

Wang Kang looked at them and said with a faint smile, "what if I have a way to raise the fire temperature?"

"Oh? What method did Master Kang come up with? " Li Zheng disdains the way.

"Blowers!" Wang Kang said directly.

"Ha ha"

hearing the speech, Li Zheng directly laughed and said: "continuous strong blowing can really help combustion and increase temperature, but do you think our Metallurgical Bureau doesn't have it?"

"The wind power of the blower is limited, and if you want to maintain firepower, you must keep blowing, which requires a lot of manpower. That said, it is difficult to achieve."

"My blower is naturally different from the one you use." Wang Kang light way.

"Then I'm curious. What's the blower used by Master Kang?" Master Xi asked.

"It's still in production. You'll see it then."

"It turns out that it's just another empty talk, so I'm interested in it."

Li is facing the two humanitarians beside him: "why don't we just stay here for a few days and see?"

"Well, it's not a waste of time to watch a farce then."

Several people are laughing.

"In that case, shall we make a bet?" Wang Kang said.

"Bet on what?"

"If my idea comes true, you will stay here and let me send you," said Wang Kang. "If I can't, you can do whatever you want."

"OK, bet!"

Li Zheng said directly, "I know that you count Fuyang have a lot of money. If you can't do it, you can donate 100000 gold coins to our metallurgy bureau."

After listening to this, master Xi and Wang Fuchen also have a bright eye. The metallurgy and manufacturing bureau is subordinate to the Ministry of industry. Although they are proud here, they are just craftsmen.

Among the six ministries of the imperial court, the Ministry of industry is the lowest, especially the metallurgy bureau. The Ministry of household has no funds at all.

Without money, nothing can be done, especially in the metallurgy bureau.

If you can make a lot of money, why not?

"How dare you?"

Li Zheng asked with a light smile. In fact, his heart was also at sixes and sevens. Just now, it was just a slip of the tongue. It was the lion's big mouth."Ha ha!" Wang Kang suddenly laughed, "I thought you were going to say something, but it was money that came out..."

"Well, this gambling agreement is established, and there is no need to write down the handwritten documents. With so many people around as evidence, you will not default."

Seeing that Wang Kang agreed so simply, Li Zheng was a little confused. It was a hundred thousand gold coins. Did he agree so easily?

Even if your family is rich, you don't even blink, do you?

Others are all natural. If you say anything else, you may not be sure. But when it comes to money, Master Kang will not hesitate.

Because he's good at spending money.

Since I don't understand, I don't want to. Li Zheng said with a smile: "thank you so much for your money."

"Is it too early to say that now?" Wang Kang said coldly.

"Ha ha, do you really think you can make it?" Master Xi said with a smile.

Wang Kang didn't tell them any more. When he really refined it, he would hit them in the face with reality.

Steelmaking is different from ironmaking. First of all, the fire temperature needed for steelmaking needs to reach more than 1500 degrees, which is the biggest difficulty.

If in modern times, there are oxidants to support combustion, but in ancient times, it can not be achieved, then how to do?

After thinking, Wang Kang decided to make an article on the stove. Because of the limitation of materials, the stove of this era cannot be made strictly.

This will make the heat unable to preserve, continue to pass, unable to maintain the temperature.

But now Wang Kang has fired refractory bricks, which is perfect, and he has made a new type of blower.

With the combination of the two, it is entirely possible to raise the temperature in the furnace to more than 1500.

Moreover, Wang Kang designed two underground furnaces to connect them. The purpose of secondary melting is to ensure the effectiveness. However, even so, there must be a gap in the steel produced.

But this is the maximum capacity that can be achieved under current conditions. With steel, reinforced concrete can be made to support the tunnel

And it can also make weapons It's very effective.

The reason why Wang Kang wants to keep Li Zheng and others is that he takes a fancy to their specialty. Smelting iron and steel is not an ordinary thing, and he obviously has no energy to spend on it.

Thinking about this, Wang Kang raised his eyes to them and said, "when I really refine it, don't deny it!"

"Ha ha, I'll wait and see!"

Wang Kang said confidently: "I promise that I will let you A big surprise
