Heavenly Dao Formula Chapter 224: Tapping steel

That is the scene when the gas in the furnace expands rapidly when heated, carrying burning impurities out of the furnace.

The flames gradually faded after tens of breaths, replaced by sparks that splashed from time to time-that is, molten iron.

Because the composition of these iron products is mixed and there are cavities inside, when they melt, the gas in this part of the void will burst out like an explosion, and at the same time bring a lot of molten iron.

Every eruption at the furnace mouth will cause a commotion on the scene.

The scene before them was a scene they had never seen before.

In the past smelting, it was difficult to raise the furnace temperature above 1,300 degrees, which caused the pig iron to melt slowly and could not be completely liquefied. The molten iron flowing out was as viscous as magma. The splashing sparks are the proof that the iron ingots have completely melted. After more than 1,500 Baidu, they are heavier "water", as long as they are slightly disturbed, they can splash like water droplets.

Jun Ning Wan was surprised and looked at Mo Yun, "Has no one ever thought of using Li Shu to smelt?"

"Why not?" Mo Yun replied, "However, the basic spells of Lishu cannot be effective for a long time. No wood is guaranteed to ignite, let alone gold and iron. As for those guards or blue swords who are good at using Lishu, they may be able to burn continuously, but they will not do this by themselves."

"So the most important thing is the listener spell?"

"No... the most important thing is people." At this point, Mo Yun glanced at Xia Fan imperceptibly.

To be honest, when the other person came to her at night and said this idea, her first reaction was extremely surprised. Not only was she surprised that Luo Qing would cooperate with Xia Fan in this way, revealing the details of her spells, but also surprised that the first thing that Xia Fan thought of after testing the characteristics was to use it for steel smelting.

Needless to say the former, most alchemists regard their own magic skills as top-secret things. If they don’t have enough benefits, they will not spread it easily. Obviously, Luo Qingqing trusts Xia Fan to some extent; The person is completely different from ordinary people's thinking of Xia Fan at work-in exchange for her, I am afraid it is difficult to counter-intuitively associate such a powerful ability of the listener with the melting pot.

But now that I think about it, this is what a researcher should have.

She still needs to learn a lot.

Ning Wanjun suddenly took Mo Yun a few steps to the side, and asked in a low voice, "I heard Xia Fan say that he talked to you all night that day?"

"Uh, this..." Mo Yun was a little stuck for a while, "His Royal Highness, I am not..."

"No, this is fine." The princess shook her head.

"Huh?"

"He is the only one who can talk to you technically all night, right?" She smiled at the corners of her mouth. "Don't you find yourself talking to other people, every sentence is short? Me? Knowing that Sora has an idea but no one can talk about the boredom, if you don’t have the ability to compete, the days to come will undoubtedly be a lot boring. In addition to not wanting to hurt you, I also have concerns in this area-after all What you are good at and like, I can’t make up for it."

"His Royal Highness..." Mo Yun couldn't help but feel a little moved.

"You just directed them to pile up iron ingots and organize tests. They look more glamorous than other times, as if there is light in their eyes. I am very happy to see you as a friend." The princess calmly said Grab her hand and say, "Go and do what you want, so that I won't regret leaving you in Jinxia City."

……

Xia Fan did not notice the conversation between the two, he was paying attention to Luo Qing's state, "How do you feel? Is the consumption of qi a lot?"

"It is indeed a little bigger than simply controlling a dragon scale, but I don't think this is a more laborious thing." Luo gently felt the qi in his lower body and replied, "Hold on one or two like this. Time shouldn't be a problem."

It seems that Qi has great potential in energy conversion.

From a certain point of view, the power contained in an alchemist is stronger than that of a steam locomotive, but there is no way to transform the two before.

Considering the specific manifestation of spells, this is probably the lowest estimate.

"The position of the sword began to sink." Luo gently reminded suddenly.

This means that the upper layer of pig iron has basically melted, and the flowing molten iron is filling up the gaps between each wrought iron below.

For this experiment, he almost collected all the raw materials in the Jinxia City weapons warehouse and the city's blacksmith shops. If you want to smelt these iron ingots into steel according to the method of the Ministry of Industry and Commerce, a hundred people will have to be busy for a month or two, but now it is less than two quarters of an hour. The first step of the process is also the most difficult. The first step has been fully achieved.

The next step is to mix the pig iron with the wrought iron as much as possible. If quality is the pursuit, the smelter usually clamps the wrought iron sheet with huge iron tongs and rolls it repeatedly in the molten iron to make the contact more comprehensive. This is essentially a helpless approach under the limit of furnace temperature. Xia Fan obviously had no such worries. He relied on the dragon scales to further heat and melted the wrought iron with a melting point of more than 1,500 Baidu. Both became molten iron. The best mix.

This is the second step and a step beyond the times.

It represents the possibility of fast and efficient production~IndoMTL.com~ Two quarters later, Luo lightly signaled that the blade was no longer sinking, undoubtedly the liquid level in the furnace had reached its lowest point.

Xia Fan nodded towards Mo Yun, "It's time."

The latter stepped forward two steps and ordered loudly, "Ready to open the stove!"

"Yes! Open the furnace door!"

Under the pull of more than ten people, the hemp rope pulled the heavy furnace door out a little bit-its length and width were less than ten inches, but the longitudinal distance was more than one arm, like a plug blocking a leak .

The moment it was pulled out, orange-red molten iron spewed out instantly!

Under the tremendous pressure, even the ten-inch-long base made this hot red flame rush out seven or eight steps away.

Someone in the crowd started cheering.

Regardless of the final result, this liquid flowing down the groove means that the iron ingot has completed a new smelting.

"Prepare for mold installation! Don't let molten iron spill into the ground!"

"Yes!"

At the other end of the trench, soldiers have placed a large number of stone molds side by side at the inclined opening.

This harvesting process will continue for a long time.

Xia Fan and Mo Yun, the princess and others came directly to the modelling area.

The blacksmith who had been waiting here skillfully selected a wide and flat stone mold, picked up the red iron bar in it, and threw it into the bucket prepared in advance. When the water vapor dissipated, he took out the iron bar and placed it on the iron felt, and began to beat it with a hammer-soon, the iron bar was knocked out of a bend of nearly ninety degrees.

Then he picked up a steel drill and slammed it against the iron plate several times until a little silver-white gap appeared on the surface.

After completing these two tests, the blacksmith reported to the princess excitedly, "His Royal Highness, Caomin dare to use 20 years of experience to guarantee that the iron produced by this furnace is indeed steel!"
