Zhang Dayuan is not stupid, now that there is a blast furnace for ironmaking, Mr. Su does not need to use this simple open-hearth furnace at all.

Mr. Su must have done this, there must be some reason!

He thought about it a lot.

The previous pig iron shower, such a good method, Mr. Su was not very happy after reading it, but looked a little unhappy.

Later, they got the stove.

It's weird no matter how you look at it!

Unless the things refined in this furnace are not ordinary, Mr. Su doesn't need to bother at all!

But the raw materials in it are clearly used for ironmaking!

So what will be the result of this?

Pig iron?

Wrought iron?

Or steel?

Either way, he'll have to try it for himself!

This Mr. Su can think of a way to give birth to an iron shower, how can this thing be ordinary?

If he can really make good molten steel, he will make a lot of money!

The more Zhang Dayuan thought about it, the more excited he became, so he said righteously: "Mr. Su, don't worry, I still have a lot of strength for the steward of this ironworks!"

So I'll do it myself! By the way, please Mr. Su stand farther away, you can't be fine! ”

Seeing that he insisted, Su Jinli thought that he was the steward of this ironworks after all, and it was arranged by Emperor Yong'an. , it is not appropriate to let someone else come.

Even if Zhang Dayuan didn't dare to do anything to her, he was in charge and managed all the blacksmiths, so he might give the other party small shoes to wear.

She couldn't be here every day, and she didn't know if any blacksmith wore little shoes.

It's better to fulfill Zhang Dayuan's wish.

Anyway, the molten iron or molten steel has already solidified, even if the crucible really explodes, there is no need to worry about the high-temperature molten steel in it blowing up and scalding people.

Su Jinli agreed: "Then come on, be careful, don't get hurt." ”

Zhang Dayuan got her approval, and immediately shouted excitedly, and then raised the big iron tongs and headed for the nearest crucible.

It's just that his luck doesn't seem to be very good, and as soon as the tongs catch the crucible, the crucible explodes.

Fortunately, the tongs were long enough, and everyone was far away, so no one was hurt.

The contents of the crucible had solidified, and after the crucible exploded, Zhang Dayuan simply pinched out the contents of the cauldron.

When placed on the ground, it obviously does not look like a pig iron ingot.

Zhang Dayuan and the blacksmiths present were shocked.

Could it be that this is wrought iron?

Su Jinli was curious, could this thing be steel?

However, looking at its appearance, it seems that there are still a lot of impurities.

I don't know what the others are like.

Su Jinli asked Zhang Dayuan to continue.

Zhang Dayuan was actually stunned when he saw the iron ingot, and he couldn't wait to see if it would be wrought iron.

So he kept staring at it, and didn't continue to take the rest of the crucible.

It was only after hearing Su Jinli's words that he reacted and continued to clamp the second crucible.

This time he was very careful, for fear of blowing up again.

Fortunately, his luck seemed to be good this time, and the crucible didn't explode.

So he carefully took out the crucible and placed it next to the iron ingot.

Su Jinli personally took a pencil and a notebook and took notes on the side.

She used a sketch technique to draw everything in the stove.

No way, there is no camera at this time. She has it in the space, but she can't just take it out and use it.

It's digital, and it's rechargeable. The photos you take are stored in the data card, and you can't use it when the battery runs out.

It's better to draw it by hand.

Su Jinli drew the situation in the furnace, and then began to draw the crucible that was taken out.

She asked Zhang Dayuan to pick it up in order, and after taking it out, she also placed it in the position in the stove.

Then she began to inspect the crucible that had been taken out.

After the damage was recorded, the crucible was opened, the ingots were removed, and they were forged to check the quality.

Blacksmiths work with steel all day long and are familiar with it.

Even if you close your eyes, you can see the quality of good or bad.

Leave this to them, absolutely no problem.

However, Su Jinli had to check the situation of all the crucibles and make records, so he couldn't leave for a while.

She stayed by until she had finished recording the condition of each crucible before going to the place where the iron was struck.

Here, the blacksmiths are in full swing.

Due to the lack of blacksmiths, the quality of all iron ingots has not been checked yet.

However, judging from the results of the current detection, this steelmaking can be regarded as relatively successful.

Because the recipes are different, the things that come out of the crucible are also different.

There are wrought iron, as well as low-carbon, medium-carbon and high-carbon steel.

Of course, these three kinds of steel were divided by Su Jinli himself according to the blacksmith's test results.

Although blacksmiths can distinguish the quality of steel, they do not understand the elements, so they naturally do not know the division of low carbon steel, medium carbon steel and high carbon steel.

However, Su Jinli looked at those blacksmiths who were busy and uncultivated, and was a little "ready to move".

She used to see her friends obsessed with making weapons all day long, and she didn't understand.

Now that she's here, looking at the busy blacksmiths, she finds it a little interesting.

Forging a true sword is not an easy task for blacksmiths.

Due to the limitations of materials, many blacksmiths are unable to craft a true sword in their lifetime.

And the real treasure knife is also a rare treasure when you look at the whole world.

Su Jinli wants to try it now.

The main reason is that she has a lot of strength now, and the job of striking iron seems to be quite easy for her.

The first time I used a crucible to make steel, I made it, and such a good thing is worth commemorating, right?

What could be more monumental than building a knife yourself?

The more Su Jinli thought about it, the more excited he became, so he personally picked out some steel ingots, and then opened a separate iron-striking room and began to lock himself in it to make iron.

Zhang Dayuan didn't know her identity, but he was still scared.

No way, even if Su Jinli disguises himself as a man, he looks like a handsome young man.

No matter where you look at it, it doesn't look like iron.

Zhang Dayuan tried to stop him, but how could Su Jinli listen to him?

So he could only watch Su Jinli lock himself in.

After the door closed, he couldn't help muttering in his heart: Mr. Su's thin arms and legs can afford to carry a wrought iron hammer?

Who knew that the fox was suspicious, and the sound of "clanging" iron sounded in the house.

Zhang Dayuan's eyes widened in shock, but after a while, he shook his head and decided to stare at the blacksmiths.

Anyway, he can't do it, and the thin Mr. Su can really hit the knife.

Even if he exerts all his strength now, he barely picks up the wrought iron hammer, and it will soon be impossible to carry it.

Zhang Dayuan firmly believes in this!

He was now waiting to see when Su Jinli would give up.

Before he had gone far, the sound of striking iron from the house became dense.

It's as if there are a lot of people knocking.

This is strange.

There are only two people in the house, Mr. Su and his little servant!
