Long Ao rested in the imperial capital for a few days, and asked the four girls to accompany their family at this time. Because there were still many things to deal with in the territory, Oaks and the four generals were eager to get the equipment right.

When he was fighting with the Sun-Battle Empire, he urged Long Ao to return to his territory.

With the farewell of the four generals, Long Ao also took everyone on the road back to the territory! The sneakyness when he was still here was different. This time, Long Ao made a show and took Ao Longjun with him.

Returning to Texas openly.

On the way back to the territory, the Longteng Empire and the Sun-Battle Empire were nervously preparing strategic materials. As soon as Long Ao's equipment arrived, the war between the two countries was about to begin.

It's right.

After returning to the territory, Long Ao asked the quarantine officers who came to the territory with him to collect equipment and loaded them into the car and sent them back to the imperial capital to His Majesty and the four generals. When Oaks and the four generals left, the quarantine officers

Later, Long Ao asked Hera to put equipment in the ring to send it to the Sun Bulai Empire, because the number was too large, it could only be sent in batches. Other countries had to prepare iron ore after returning to China, so they had to

It will take a while to come.

Long Ao took advantage of the fact that he was fine and started planning the drawings. After busy for several days, he finally designed the drawings. After the drawings were designed, Long Ao quickly handed the drawings to the craftsmen to see. The blast furnace is a

A vertical cylindrical furnace, the outside of the furnace is riveted to string iron plates into outer shapes, and then stones are built inside. There is a geometric space inside the blast furnace.

The furnace shape consists of five parts: the throat, the furnace body, the furnace waist, the furnace belly and the furnace cylinder. After passing the busyness of the craftsmen and soldiers, the furnace body is built, and finally the key furnace top is

The charging device. Especially the installation of two large and small material clocks. The function of the two material clocks is to open and close alternately during use to prevent gas in the furnace from escaping. An air outlet is provided in the furnace cylinder part to produce slag

The ports and iron outlets, air outlets and slag outlets are cooled by water cooling devices to prevent burning at high temperatures.

There are also sinks below the middle of the furnace body to prevent the furnace shell and the furnace lining from burning out. Since there is no modern automatic feeding system, the feeding work must be done by people, considering

To the safety reasons, Long Ao built the blast furnace under the hillside of Qiangu, with the charging port parallel to the hillside, which facilitates transportation and people can quickly disperse when danger occurs.

The next thing is the air supply system. During the smelting process, the heated air must be continuously swelled to reduce fuel consumption. The fan does not have it, but Long Ao has designed it long ago.

The bellows are used for blowing, and under the pre-existing conditions, it is not important to think of ways to consume more fuel. Then a huge chimney was built to use it.

Exclude smoke and reduce pressure.

After the blast furnace is built, the next one is a steelmaking furnace. The furnace is lying down and is made of refractory stone. It is divided into acidic and

Alkaline open furnace. The size of the open furnace is expressed according to the amount of steel output. The open furnace is lower than the blast furnace and is located below the iron outlet of the blast furnace. It is mainly to facilitate the addition of the blast furnace to melt.

molten iron.

It was already a month after these preliminary structures were completed. Other countries had already traded, and Long Ao exchanged a large amount of iron ore for steelmaking. And the arsenal was completely

It's empty.

Because coke is one of the first materials for steelmaking, Long Ao purchased a large amount of coal while building the blast furnace. Then he installed the bellows on the blast furnace. After these preparations were done, Long

Ao has built another blast furnace for coke refining. The carbon is much easier than steelmaking. You only need to dig up the coal mine and heat the compartment to coke.

After all the preparations were in place, Long Ao looked forward to the successful manufacturing of steel with confidence.

The steel manufacturing process is busy and complex here. The huge momentum of 50,000 people took half a year, spent three million kilograms of grain and thousands of dollars.

Ten thousand. But Long Ao now has more money without more than anything. He has failed twice. Long Ao's third furnace is finally about to be released.

Long Ao looked at the sky and knew that the time was almost over. He shouted, "Open the gate!" More than a dozen dwarves ran over and pulled hard. The flood-like steel poured out and headed straight down.

Chen Ying shouted excitedly: "It's out of steel, it's out of steel."

A large pond of steel slowly solidified and formed, (1^6^k^The fastest update) Long Ao estimated that it should be hundreds of thousands of kilograms, and these will be immortal wealth. "Brother

We are on three days off today, and everyone can eat and drink as much as possible." Long Ao's shouting inspired another burst of lively Gao Chao.

The steel was released and made into equipment by Long Ao. First, the dwarves replaced all the equipment of the Ao Long Legion with steel. The weight of a set of steel was not as good as before.

Half of it, but the defense of armor and the killing of weapons have been greatly increased. However, Long Ao is not planning to sell steel equipment, so of course he has to keep the good things for himself! Long Ao strictly prohibits
