Wang Fuli didn't know how to express the mood in his heart, and the unobtainable 'snowflake salt' was so easy to get? !

Why? Whatever it is.

Wang Fuli sighed very much, the 'little sister' of Yaozhai gave her life for this, it was not worth it.

Li Dawei asked everyone to get up and said: "Everyone has seen the whole process, you are willing to work for me, I will let you have no worries about food and clothing, and you will be responsible for the production of 'snowflake salt' in the future, everyone should pay attention to the confidentiality method." Oh, get the rest of the salt. ”

Wang Fuli appointed a person in charge, and then followed Li Dawei to another place.

If you want to pick up a girl, you have to have equipment, and dressing up is indispensable.

Li Dawei has always been wearing this kind of semi-Orion dress, comfortable and comfortable. Now those people's clothes are very complicated, and Li Dawei himself pondered that he might not be able to wear them.

Shoes are not divided between left and right, what do people in this era think, don't you feel awkward? Use a pile of mud to make a foot mold, and after thinking about the style, it is still made into a half-boot shape, or there is no place to put the three-edged thorns.

The pattern of clothes and pants is really special for everyone. Wang Fuli is a little insightful: "This is... Hufu? Then he nodded: "It's a lot easier to move when you wear it like this, but it's like this..."

"Hehe, it's not a hufu. As for the style, everyone's aesthetic is different, everyone just needs to do it according to my ideas, it doesn't matter if you do it wrong, just change it slowly. Li Dawei smiled: "In the future, everyone will know the benefits of this kind of clothes." ”

The singing 'Ah Xiu' is the person in charge of this group of people, and he is ingenious. After measuring the size, Li Dawei continued to be busy with himself, while Wang Fuli stayed. Changing the name is secondary, and the thinking must be unified.

Blacksmith 'Xiong Da' led a group of people who were also busy, and the four bears were also busy.

The simple stove has been set up, the charcoal is burning, and Xiong Da has the familiar feeling he had before. Differently, Xiong was surprised to find that the temperature of the flame was much higher than before, and with such a temperature, he would definitely be able to make good iron.

There are a lot of iron blocks, and Li Dawei has never used them.

The horse's shoe must be nailed, otherwise the horse's hooves will be broken, and no matter how good the horse is, it will be a 'groove horse'

You need a set of distillation equipment, these wines are too hard to drink, and get a bit of a high sense of search. If you want to go to the daughter of the 'city lord', you have to have some greeting gifts.

The four bears are strong enough, and the blowers are about to fall apart when he summons them, and the furnace is perfect, and the iron melts very smoothly.

At this time, the iron impurities are many and brittle, and they are of little use except for making containers. It needs to be constantly beaten, quenched, and reduced in impurity content. Effortless and laborious does not work.

To put it simply, it uses the principle of thermal expansion and cold contraction, when quenching, iron shrinks, but carbon does not, so that impurities will be 'squeezed' out.

Repeat to reduce the carbon content and distribute it evenly. This is the principle of 100 steel refining.

Of course, Li Dawei will not use this method. To reduce the carbon content, there is a high school textbook, and the full name is 'oxygen top blowing converter steelmaking'.

To reduce other impurities, especially gangue (the main component is silica), as well as sulfur, phosphorus and other impurities, you need to add limestone, as for special steel with special requirements, then we will talk about it later.

The principle is very simple, this kind of 'small workshop' is not counted, steelmaking with pig iron as raw material is not difficult, but the quality is certainly not the same level as that of later generations.

In fact, you can also use the 'steel filling method' and 'steel frying method', which is simple and easy. However, in the long run, 'oxygen top blowing converter steelmaking' is an ultimate goal, so let's start to lay the foundation, explore, practice, and accumulate from now on.

Blowing oxygen, there is no pure, only air. However, this low thermal efficiency and the presence of nitrogen in the air will have some impact on the quality of the steel, and this problem will be solved later.

Chen Ergou doesn't know how to make iron, but he knows how to burn charcoal; Coking was just learned, but he could clearly feel that the so-called 'coke' burned not only smokeless, but also much warmer than charcoal.

'Xiong Da''s face was flushed, I don't know if it was hot or excited.

When this pot of molten steel comes out of the oven, it is stronger than the '100 steels' that I have been beating for several months before.

'Poof' knelt down, Xiong Da swore that this law would never be passed on. When he heard that 'there are still many imperfections in this method, the quality of this steel is average, and I will slowly teach him in the future', Xiong's head was broken.

Making shoes for horses makes people wonder: what shoes do horses want?

What a noble act to make shoes for horses out of refined steel. and the emperor with a gold hoe to work.
