Datang: Time travel in two months, wait online, hurry up!

When Li Ke came to the iron-making workshop, it was completely different from the last time he came here.

There are a few more modern blast furnaces here.

It was completely built according to the drawings he gave.

With the skill of the artisans of the Ministry of Industry, the repair of these blast furnaces is naturally fast and good.

Next to the preheating room, the blower is also built.

And what he specifically explained before, the coking furnace has also been built.

Everything is in place, ready to start making steel!

"His Royal Highness, all the furnaces have been built according to your drawings, do you think they meet the requirements?"

The little supervisor led a group of craftsmen and looked at Li Ke expectantly.

The news that Li Ke threatened to increase steel production tenfold and hundredfold had already reached the Ministry of Industry.

Outsiders may not understand, but they still have great confidence in Li Ke!

After all, on the first day Li Ke came, he directly put forward a proposal that could greatly increase steel production.

Definitely a top expert!

So after hearing Li Ke's rhetoric, everyone is looking forward to this day!

"You are all the top craftsmen in my Tang Dynasty, so the stove you built is naturally no problem!"

Li Ke praised the craftsmen of the Ministry of Industry without hesitation.

"Next, we will officially start work!"

Li Ke didn't waste any time and directly announced the start of work.

Start work one day earlier, and pay for it one day earlier!

"Turn on three furnaces at the same time, two for ironmaking and one for coking!"

Li Ke directly arranged the next work.

The most important thing now is the upcoming spring plowing, which requires a lot of pig iron to cast the plow of Quyuan plow.

In addition, the coke hadn't been smelted yet, so he planned to smelt iron first.

When the coke is smelted, then steel and iron will be smelted together!

Since it was the first time for the artisans of the Ministry of Industry to use this kind of blast furnace to make iron, coking has never been done before.

So basically Li Ke is guiding them.

Fortunately, everyone is a top craftsman, but they are a little unfamiliar at the beginning, but they quickly get used to it.

"Your Highness, can this coke really raise the temperature of the furnace so much?"

A craftsman couldn't believe it.

Steelmaking is expensive and difficult.

It is because the furnace temperature cannot reach.

But with coke, the furnace temperature can be greatly increased, and the temperature in the blast furnace can be easily raised to more than 15 degrees!

At this furnace temperature, steelmaking is much easier.

The speed of steelmaking has been greatly increased, and the quality of the steel produced is also good.

"Of course, when the coke is smelted, you can try it and you will know." "

Li Ke smiled slightly, his tone full of confidence.

Next, both the ironmaking and coking processes went very smoothly.

Li Ke has epoch-making theoretical knowledge, and the craftsmen of the Ministry of Industry have the top practical skills of this era.

Combining the two, wouldn't it be easy to catch?

The first is ironmaking. After there is a preheating chamber to heat the air, the blower blows the heated air into the blast furnace.

In this way, the temperature in the furnace rises rapidly!

The impurities in the iron ore are quickly melted away by the high temperature, and high-quality molten iron is refined!

"So fast!"

It didn't take long to see that the molten iron came out, and based on their years of experience, the quality of the molten iron was very high, and the impurities were the least they had ever seen!

"Quickly prepare the mold!"

The craftsmen immediately got to work.

The plow of Quyuanli does not need to be beaten, so it can be made of pig iron and directly made of molds.

Pour the molten iron into the mold, and after cooling, handle it a little bit, and it will be a finished plow.

Next, a furnace of molten iron was poured into the mold, forming plow-shaped red iron blocks.

Then, continue to add iron ore and ingredients to it, and continue heating!

A furnace of red molten iron is smelted and then poured into a mold.

Compared with before, the whole output has increased by an unknown number of times!

"His Royal Highness King Wu is mighty!"

All the craftsmen looked at Li Ke with great admiration.

After all, it was just a theory before, but now a furnace of molten iron has been actually smelted!

And the speed and efficiency are too high!

"Next, we will continue to build the blast furnace."

Li Ke had expected this for a long time and was not surprised.

He just told everyone to continue building the blast furnace.

There are still too few furnaces in front of us, and they are far from being able to supply the steel demand of the whole country.

"Yes!"

The craftsmen of the Ministry of Industry responded in unison.

I didn't know how to repair this kind of stove before, but now, as long as there is room, I will repair them all!

"The Ministry of Industry has always been at the bottom of the six departments, and everyone's status and treatment are also the lowest. You have suffered a lot on weekdays, right?"

"Trust me, as long as everyone acts according to the standards set by me, our Ministry of Industry will become the leader of the six departments in the future!"

"This king will let the artisans of the Ministry of Industry have the most generous treatment and get the highest status!"

Li Ke is well aware of the role and power of painting big cakes.

So Li Ke directly took this opportunity to start painting big cakes for the artisans of the Ministry of Industry!

Of course, his cakes were not drawn casually.

The cakes he drew can be realized in the end!

"Follow the orders of His Royal Highness King Wu!"

After hearing Li Ke's words, all the craftsmen immediately became excited!

As Li Ke said, they were so angry before!

Just because their Ministry of Industry is at the bottom of the six departments, their salary is also very low!

Now, Li Ke directly threatened to make the Ministry of Industry the head of the six departments, and let them have the most lucrative treatment and the highest status of the six departments!

How does this not make their blood boil?

As for whether what Li Ke said can be achieved?

They now blindly trust and worship Li Ke!

As long as Li Ke says it, it will definitely come true!

Moreover, as long as they can really increase steel production by a hundredfold, it is not impossible for the Ministry of Industry to become the head of the six ministries!

But now, they are full of confidence in increasing steel production by a hundredfold!

Li Ke's words directly mobilized the work enthusiasm of the craftsmen.

Now everyone is fighting for the glory of the Ministry of Industry!

Next, the first batch of coke was smelted out.

Under the guidance of Li Ke, the craftsmen couldn't wait to start the first furnace of steel in the newly built blast furnace!

Without any accidents, when coke became the fuel for steelmaking, the problem of insufficient furnace temperature was immediately solved!

Although all the craftsmen were dripping with sweat due to the high temperature, everyone's faces were full of excitement!

This means that the problem of steelmaking has been completely solved!

As long as there are iron ore, coke, and blast furnaces, there will be continuous energy to make steel!

"His Royal Highness, the first batch of steel has been smelted, and the strength and quality are very high!"

The little supervisor led people to inspect the first batch of smelted steel, and his face was full of excited smiles.

The speed of steelmaking is fast, and the quality of the steel produced is good, and the strength is also high!

Now the Ministry of Industry is really going to show its face!

"When you usually make steel, you should also pay attention to researching new materials."

"For example, in steelmaking, adding a certain amount of other materials into it can strengthen the characteristics of steel."

In order for steel materials to develop more vigorously, Li Ke also instilled some research and development theories into them.

For example, adding a certain amount of chromium to steel can increase the wear resistance and corrosion resistance of the steel. If it has more than 13%, it is considered to be stainless steel!

This kind of material will definitely be needed for shipbuilding in the future.

For example, adding molybdenum to steel can prevent the steel from becoming brittle and maintain the strength of the steel at high temperatures.

This kind of material will definitely be needed when making guns and cannons and steam engines in the future.

Therefore, explain some theories in this area to them in advance, and let them study and study at ordinary times.

It can not only produce the materials he needs, but also cultivate their scientific research ability.

It can be said to kill two birds with one stone!

"¨Yes, Your Highness King Wu, I will experiment later!"

The craftsmen nodded without hesitation.

Now Li Ke's words are probably more effective to them than imperial edicts!

Li Ke inspected around and found that everyone was on the right track, and the follow-up work was also arranged.

So, he came to the place where Duan Lun, Minister of the Ministry of Industry, worked.

"Uncle, let's drink tea."

Li Ke saw that Duan Lun was drinking tea and reading a book leisurely, as if he was fishing at work.

"Saburo is here? Sit down!"

When Duan Lun saw Li Ke coming, he immediately greeted him with a smile.

In the past, his position as Minister of the Ministry of Industry was also the lowest among the six ministers.

But recently, with Li Ke's arrival, he can be said to be in Li Ke's light, and he is in a good mood.

In the future, the steel output of the Ministry of Industry will increase by a hundredfold. At that time, the status of the Ministry of Industry will not increase?

Moreover, he just received news that the new blast furnace lived up to expectations, whether it was iron or steel, it was fast and of good quality.

The efficiency has been increased by an unknown number of times!

Hearing such good news, he naturally felt much better.

"Uncle, brothers and sisters will settle accounts, and then we have to talk."

Li Ke didn't come to catch up with Duan Lun, he came to discuss business seriously!
