Chapter 129 Converter Steelmaking
The human-powered rail car is not a single one. The blacksmiths in the smithy jointly make four human-powered rail cars. Each trip can transport up to 2 pieces of ladles, and it only takes one to two minutes to go back and forth, which is convenient and fast.

The slave spies were very excited to grab another lion-man slave. He had a scar on his face, and he was also a secret spy from Nitre Town. The two would exchange the information they got today when they ate every day.

Now the slave spies can't help but share their joy with their companions. The appearance of the human-powered rail car is enough to prove that this emerging town has advanced invention technology.

In addition, the white mist in the ironworks is transpiring, sparks are splashing, and there are often terrifying scenes of high-temperature molten iron flowing down the channel. Those slaves often use certain things to collect high-temperature molten iron. It is hard to imagine how they seriously Work.

Anyway, the intelligence agent Lionman had wanted to spread the information about the ironworks for a long time, but the work in the ironworks was too strict.

Although the secret of the ironworks is not as high as that of the gunpowder factory, the orcs working here have the same ground rules. They can't run out of their own range, and they can't sleep outside the slave shed of the ironworks.

Last night, he tried to pee at night, checked the surrounding security facilities, and found that many soldiers in the town were not patrolling, so the night was the time for the carrier pigeon to send messages.

Taking advantage of everyone's attention looking at the steel factory, he whispered to his companions: "This human-powered rail car is very powerful. It doesn't need animals. It can be driven by human power. This is a very critical technology. Can you Can you draw the structure diagram of the human rail car?"

"Yes, but I need to read it many times, otherwise I will be punished if some details are wrongly drawn." The lion-man spy who is good at drawing said in a low voice.

The slaves around were all immersed in the miracle of doing miracles vigorously, and their minds were overwhelmed by fanaticism, and they did not pay attention to the whispered exchange between the two thieves slaves.

rumbling.

The molten iron that has been sanitized is poured into a large converter, and scrap steel bought from various places is also poured into the converter. In addition, there is a thin pipe protruding into the furnace, which is an oxygen gun.

The oxygen comes from the orc laboratory in Tomorrow Town. Allen used his full-level teaching ability to teach the 200 slave team into experimenters who memorized the steps.

Firstly, using the heat-absorbing properties of saltpeter, a large amount of high-purity oxygen will be produced by using the air freezing separation method.

The oxygen cannot be guaranteed to be 100% pure. It is a very powerful technology to be able to infuse oxygen under the existing conditions.

Then use steam engines and rubber pistons to make gas pumping and gas transporting materials, and input a large amount of oxygen into the steel airtight container made by the smithy.

The initial cost of the air cryogenic separation method is high, but it becomes easy after success. The output is high each time, and the air sources are also inexhaustible, which can be used casually.

After a while, when the converter rotates, the refined molten steel flows out from a specific channel and is poured into a container to be determined, and steel cracks will be formed after a period of time.

"Master Alan, I saw the converter design drawing of the steel plant a month ago. To be honest, I am still ignorant. I don't really understand the oxygen gun and the side blowing of alkaline air. Can you tell me the principle?"

Abel scratched his hair. After seeing the successful operation of the converter, he didn't bother to check the quality of the steel. He couldn't wait to understand the deepest secrets of converter steelmaking.

Allen hummed, remembering that he had recently written a junior high school chemistry book, and said, "This requires you to go to school to learn chemistry."

"Chemistry?" Abel didn't understand the word, so he had to bite the bullet and remember the term.

God of casting, steelmaking is not in your natural domain. Do I have to believe in the god of chemistry?Abel murmured in his heart.

"That's right, but the chemistry class hasn't started yet, and the chemistry class will start in a day or two, and the chemistry laboratory in the school will also be preliminarily installed by then." Allen nodded.

Chemical experiments require a variety of transparent glass test tubes and rubber tubes, which require the support of glass factories and small rubber workshops.

The Windsor cat ears moved slightly, eavesdropping on their conversation.

"Chemistry book, didn't you tell me to take it to the printing factory to print hundreds of books yesterday?" Windsor's thoughts changed slightly.

Steam engine needs physics, steel making needs chemistry?
Windsor secretly remembers the basic subjects these industrial machines need, and only after they have learned them thoroughly can they understand Allen's management.

Allen didn't know the complicated thoughts of the people around him. After watching the converter run for a while and confirming that the steelmaking plant was operating normally, he began to assign the next strategic task-casting steel cannons!

Cannon is the god of war!

"Well, now that the converter is successful, it's time to make the next large weapon." Allen murmured.

Alan didn't hide his voice, deliberately letting the orcs around him hear this sentence.

With the converter steelmaking method, and because of the three-stripping treatment of molten iron, the quality of steel produced is different from the past, and the quality of cast steel cannons has also risen linearly. It is time to manufacture cannons.

When the orcs heard Allen's words, they immediately put chemistry behind them, and all the thoughts that came to their minds were muskets, flintlock guns, muzzle-loading guns and other words.

"What's the next big weapon, is it a gun?"

"Since it's a large one, it should be a large musket."

Powerful weapons can give villages and towns a great sense of security. With them, they will no longer be afraid of the infestation of random beast hordes, and at the same time, they will not be afraid of the Lionheart Kingdom's fall.

"You guessed it right, it is an enlarged version of the musket, but its shape is a little different from what you thought." Allen shook his head, and led everyone into the office of the director of the steel factory.

There are not many orcs who can participate in the training, because this is a new technology and new secret. Most of the orcs who come to listen are blacksmiths in the blacksmith shop, and a few are orcs such as Windsor and the director of the steel factory.

When all the orcs who were due to come gathered in the office, Alan reached out, and Windsor understood, and took out a strange design drawn a few days ago from the small bag.

The white blueprint was placed on the table and spread out slowly. The orcs saw a huge steel pipe with a moving structure of two steel wheels underneath.

Its buttocks are round and huge, and the "barrel" is thinned in the front and middle.

Even so, its "mouth" is still huge, at least much larger than the [-]mm caliber of a flintlock.
