People are in the Tang Dynasty, creating a mythical dynasty

Chapter 77 Blast Furnace Ironmaking
In fact, it is true.

After Li Ming returned to Shaofu, he started to prepare.

First of all, the craftsmen from the Shaofu and the officials sent by the Ministry of Industry began to be summoned.

At the same time, he selected the materials about reservoir construction and blast furnace ironmaking from the books he signed.

It has to be said that in the past half a year.

Something he signed.

Especially in terms of technology, there are really many.

After sorting this out.

Only to find that there are as many as twenty or thirty copies.

"These are information related to ironmaking and reservoir construction. Take a look and give me a plan as soon as possible."

When he spoke, he turned towards the more than 20 officials from the Ministry of Industry and more than a dozen officials from the Shaofu.

"promise!"

More than 50 people responded quickly.

And after explaining these people.

Li Ming has to check on the pig raising and the purchase of locusts.

The original workload can be said to have increased a lot in an instant.

Fortunately, the people from the Ministry of Industry and the Shaofu are extremely powerful.

Just less than three days.

The technology related to blast furnace ironmaking was sorted out.

"Your Highness, this method is extremely feasible."

"I don't know where your Highness came from, but this is an artifact of the world."

A Shaofu official looked at Li Ming with bright eyes, and his expression was a little excited.

While sorting out the materials, he couldn't help being shocked.

The ironmaking technology mentioned in this material is something he has never been exposed to, nor has he ever seen it.

Although he didn't try it, but in that few words, he could somehow feel that it was feasible.

And it certainly thrilled him.

Because of the output described above, it really made his scalp tingle.

If Datang could really produce a large amount of steel as described in the book, its effect would be unimaginable.

"The method is obtained from the father, what do you need?"

"As long as it can be satisfied, this king will definitely be satisfied, but within half a year, this king needs to see more than 30 catties of steel, whether it can be done."

Li Ming casually explained the inquiry from the officials of the Shaofu, but the words turned to iron smelting.

To build a reservoir, the steel required is undoubtedly tens to hundreds of tons, and this is still the beginning.

Therefore, Li Ming must ensure that the ironmaking can reach this value.

It's just that after he finished speaking, he was also a little nervous.

This is not after all.

In the later generations, the production of ordinary steel is more than 500 million tons a year; the production of special steel is more than 300 million tons to be called a large-scale enterprise. Even small steel factories in rural areas have a monthly output of several hundred to thousands of tons.

But that is the result of various high-tech equipment and sufficient supplies.

In this more than 1000 years ago.

Without all kinds of high-tech equipment and sufficient materials, it is not so easy to ensure sufficient production.

"30 catties, half a year?"

"Your Highness, if what is said in this book is not bad, I think 50 jin, or even a million jin is not a problem."

The Shaofu official spoke with affirmation in his voice.

"it is good!"

"You start organizing the manpower now, and all the remaining resources and manpower of the Shaofu will be mobilized by you."

"Within half a year, this king needs to see your achievements."

Li Ming nodded and agreed directly.

"promise!"

Shaofu officials responded quickly.

Then the mighty iron smelting began.

The first is the indigenous blast furnace, the first one gradually stands up.

"Increase the firepower!"

"Yep!"

"that's it!"

Loud voices were shouting.

And more than 1000 years ago, the first blast furnace ironmaking also started in this kind of shouting.

The raw materials have already been prepared.

iron ore, and coke.

That's right, coke.

Raw coal cannot be made into steel, it can only be made after coking.

Coking refers to the process in which coking coal is heated to about 1000°C under air-isolated conditions, and coke, coke oven gas and other coking chemical products are produced through thermal decomposition and coking.

Among the technologies signed in is the most complete coking technology.

Nature is not too difficult.

Just one day.

Coal has been coked.

And reaching this step can naturally start steelmaking.

Nowadays, the steelmaking methods compiled by the people in the Shaofu and the people in the Ministry of Industry from various technologies in the previous life cannot even be regarded as a complete indigenous method of steelmaking.

In the previous life, the indigenous method of steelmaking, because the production conditions were too crude, the steel produced contained a lot of impurities, and the standard of carbon added was different, there were no professional tools, the bubble content in the steel was too large, and the structural strength was low, which was far away. Does not meet application requirements.

But now, although there are still some problems, the method that has been sorted out by dozens of people, or even hundreds of people who are the most elite craftsmen of this era, is undoubtedly more perfect.

Only the first furnace has been declared a success.

And the effect of steel is not as bad as imagined.

For a moment, people couldn't help but get excited.

Further adjustments began immediately.

Less than ten days to come.

Blast furnace ironmaking is continuously opened and smelted.

The quality of the molten iron produced began to improve rapidly.

Until the afterglow of June gradually came to an end.

The blast furnace was thoroughly determined.

Compared with the worst blast furnaces, today's blast furnaces are more complete, and the quality of the molten iron produced is sufficient to meet the standards.

There is not much difference in the quality of some ordinary steel products in later generations.

Arriving at this moment can be said to be perfect.

After all, special steel cannot be refined by this kind of local method.

Unless you have those technologies and high-tech equipment, it is possible.

But even so, these ordinary grades of steel are enough.

Among Li Ming's nodding.

At the same time, hundreds of blast furnaces began to be built rapidly within Shaofu.

More importantly, this is only the initial construction.

According to what the official from the Shaofu said.

If possible, he plans to build [-] in the early stage.

It's just that there are not many manpower and knowledge of related technologies, and one hundred seats is already the limit.

If you want to continue to build, it will take a period of accumulation.

And when the blast furnace started to be built on a large scale
The Shaofu also began to mobilize with all its strength.

A large amount of iron ore and coal mines began to be delivered.

In the previous life, there were 25 iron ore reserves in Shaanxi, with a reserve of 6.5 million tons. Most of them were magnetite lean ore, and the rich ore only accounted for about 0.2%, but that was the result of thousands of years of excavation. Today, more than 1000 years ago, there were not a few iron ore mines in Shaanxi. , and coal mines are also extremely rich.

There is an open-pit coal mine on a mountain near Chang'an.

It can completely support the large-scale ironmaking in Shaofu.

As for whether it will cause pollution.

Maybe you need to think about it in your previous life, especially the distance from Chang'an.

Available in this more than 1000 years ago.

As Guanzhong is still covered by large-scale trees, pollution is almost non-existent.
