Roman Slave Owner

Chapter 21 Braised steel

Under Li Wei’s command, a slave craftsman puts wood in the furnace one by one.

Wood charcoal and coke are impossible, otherwise the pig iron will be melted directly, it is not called carburization, and even the catalyst will be incorporated into the pig iron.

The craftsman laid some containers made of crucibles, spread the carbon powder, beef bone meal, and sawdust to the bottom layer according to a certain ratio, and then put the iron sword to be carburized.

Put a layer of carbon powder, beef bone meal, and sawdust, then put a layer of iron swords, and stack them one by one.

Beef bone meal is the catalyst for carburizing. Sometimes it will penetrate into the ironware and become an impurity in it.

Later generations have already figured out various carburizing ratios. For every 100 kilograms of pig iron, 4 kilograms of carbon powder, 20 kilograms of beef bone meal and 5 kilograms of sawdust are needed, and Li Wei directly used it.

“The bottom and upper layers should be placed a bit more, and the middle layers should be evenly placed.”

Li Wei commanded from the side.

The blacksmith put layers of carburizing agent and iron sword into it under the command of Li Wei, covered the crucible lid and then sealed it with clay.

This is braised steel. Of course, there is another container that contains sword embryos. These sword embryos are much larger than iron swords, and they are weapons that are prepared for more than ten refines.

The slave craftsman put the two mud-sealed containers into the stove and set fire to them.

The raging flames burned, and Gikes ignored the terrible temperature and controlled the furnace temperature himself.

He blasted wind into the stove through a wooden flap bellows.

There are two valves on the front and back of the bellows, whether it is pulled or pushed, it can blow the wind into the stove.

For this kind of bellows concept, Jikos simply admires it to the extreme.

“Remember, try not to exceed 900 degrees as far as possible, and you can control how much it is.”

Li Wei said.

A while ago, he gave Gikos a bit of basic knowledge, letting him know that the temperature of iron making iron is 1000 degrees, and the temperature of ice is 0 degrees, so he already has a rough impression of 900 degrees.

Geikes felt that Li Wei had opened a door for himself, and he knew how to quantify temperature. It was incredible.

What he didn’t know was that Li Wei had concealed too many things, such as the nature of steel. The best way to keep it secret was that only he knew it.

The slave kept recording on the side with parchment, and hated Li Wei for making iron by experience.

Why not use scientific experimental methods? Record all the operations and processes so that you can get started as soon as possible.

Looking at the sweat constantly flowing out of Jikos, Li Wei could only sigh that the front-end workers are really not good at work, not to mention in this era of no safety protection.

“Let people prepare more thin bean soup, remember not to limit it, you two can drink as much as you want.”

Li Wei said.

These two people will be the only slaves who know how to steer steel. He doesn’t want them to fall ill.

The slave nodded excitedly. Compared with the slave owners before, Li Wei was really kind.

The food is full, you can eat as much as you want, and there is a lot of beef and mutton in the food.

Any slave’s request, as long as it is not out of line, he will agree.

Looking at the attentive Giikes, Li Wei planned to leave here.

It takes several hours to simmer steel, and it’s really boring to stay here all the time.

asked the slave to make a record, and Li Wei left here.

played some peekaboo games with some female slaves, and Heng received an obscene spa massage.

After a big meal and a nap, Li Wei went to see how he was doing.

“Master, we made it! We made it!!”

Geikes said excitedly after seeing Li Wei, and then handed a dagger to Li Wei.

“This is the short sword you made.”

Li Wei looked at the dark dagger and said.

“That’s right, we used this dagger and the dagger we bought to slash, and after cutting off two daggers, the gap appeared. In the end, a total of eight daggers were cut off before this steel sword was broken. It’s a record of hacking.”

Geikes said while holding a parchment.

then pointed to some broken swords on the ground and said: “These cut broken swords.”

Li Wei glanced at the broken swords, and then carefully looked at the cross-cutting records.

“Yes, keep going.”

Li Wei said, and then pointed out some shortcomings in the record.

Due to lack of experience, these experimental records have great shortcomings.

Although Li Wei is not a professional, after all, people who have a vision beyond this age don’t know how many people.

Geikes’s eyes on Li Wei is like the **** of fire is alive, and the admiration in his heart is simply indescribable.

“We will continue to experiment in the next few days, and we must make the best steel sword.”

Li Wei said to him.

“no problem.”

Giikes said excitedly.

Then Li Wei left here with these short swords and sword embryos, and gave the sword embryos to other slave blacksmiths for folding and forging. I believe that a batch of ten or even twenty weapons will be born soon.

Li Wei slowly opened his eyes and found that Xiao Li Wei was standing with his head high and angrily, and there was a trace of liquid on the bed.

“It’s naughty again Li Wei suppressed him a little, then opened the curtains, and a beautiful garden appeared in front of him.

is planted with vines and various flowers. Not far away is a pond and pavilion, rockery, and water pavilion. This was specially built by Li Wei to commemorate his last life.

Several slaves worked hard in the garden. It was really a decadent slave-owner’s life. Li Wei criticized himself violently.

“Master, you woke up.”

I don’t know when, Yulia walked in.

was wearing a brown shirt with a V-neck, a touch of snow white appeared on her chest, her lower body was a short skirt covering her hips, and her pair of slender and round long legs were particularly eye-catching.

Li Wei couldn’t help but swallowed and said, “Why did you wear this suit?”

Today’s Yulia is so tempting!

“Is it not good-looking? Many people say that this dress is very good-looking, I specially made it up.”

Yulia turned around and said, “If you don’t like it, I can change it.”

The styles of Roman clothes are extremely poor. Men are Toga besides short coats, and short coats besides Toga, and toga besides short coats.

In winter, I also add a cloak made of sheepskin, and a few layers of cloak when it’s cold.

Women are better, but not much better.

Since Li Wei’s sugar shop opened, the costumes of those waiters have driven a trend, and aroused the enthusiasm of many Roman women.

“No, you actually look good in this one. If you like, I can design some clothes for you.”

Li Wei said.

He has decided to design various nurses and police costumes for later generations, and work hard to contribute to the fashion business in Rome.
