Heavenly Dao Formula

That is the scene produced by the rapid expansion of the gas in the furnace when it is heated, and rushes out of the kiln with the combustion impurities.

The flames gradually subsided after dozens of breaths, replaced by sparks that splashed from time to time—that is, molten iron.

Because the ingredients of these iron products are mixed and there are cavities in them, when they melt, the gas in this part of the gap will explode like an explosion, and at the same time bring a large amount of molten iron.

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

The scene in front of them was something they had never seen before.

In past smelting, it was difficult to raise the furnace temperature above 1300 degrees, which resulted in the slow melting of pig iron and the inability to completely liquefy it. The molten iron flowing out was as viscous as magma. And the splashing sparks are the proof of the complete melting of the iron ingots - after exceeding 15000 degrees, they become heavier "water", as long as they are slightly disturbed, they can splash like water droplets.

Ning Wanjun clicked his tongue in amazement and then looked at Mo Yun, "Has no one thought of using the Li technique to refine it before?"

"Why not." Mo Yun replied, "However, the basic techniques of Liju cannot take effect for a long time, such as Feihuayan, and the medicine needs nitrate powder, and it can only create a flow of fire once, and it can't even burn a piece of wood. Guaranteed to ignite, not to mention things of gold and iron. As for those guards or green swords who are good at using the technique of leaving, they may be able to keep burning, but they will not do this kind of thing by themselves."

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

"No... the most important thing is people." Having said that, Mo Yun glanced at Xia Fan incredulously.

To be honest, when the other party came to her at night and expressed this idea, her first reaction was extremely surprised. He was surprised that Luo Qingqing would cooperate with Xia Fan in such a way, revealing the details of his spells, and also surprised that Xia Fan's first thought after testing the characteristics was to use it in steel smelting.

Needless to say, the former, most alchemists will regard their skills as top secret, and will not spread them easily if they do not have enough benefits. It is obvious that Luo Qingwei trusts Xia Fan to a certain extent; It's Xia Fan's way of thinking, which is very different from ordinary people, at work - if it were her, it would be difficult to counter-intuitively connect such a powerful ability of the listener with the melting pot.

However, thinking about it now, this is the way a researcher should think.

She still has a lot to learn.

Ning Wanjun suddenly pulled Mo Yun a few steps aside, and asked in a low voice, "I heard from Xia Fan that he chatted with you for a whole night that day?"

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

"No, that's fine." The princess shook her head.

"ah?"

"Is he the only one who can technically talk to you all night?" She smiled slightly, "Didn't you find that when you talk to other people, every sentence is very short? The boredom of thinking in your head but having no one to talk to, without a player with comparable skills, the days to come will undoubtedly be much more boring. Apart from not wanting to implicate you, I also had concerns about this—after all, you are good at I can't make up for what I like."

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

"When you ordered them to stack iron ingots and organize tests just now, you looked more energetic than at other times, as if there were lights in their eyes. I am very happy to see you like this, as a friend." The princess grabbed her frankly He said, "Do what you want to do, so that I won't regret leaving you in Jinxia City."

...

Xia Fan didn't notice the conversation between the two, he was paying attention to Luo Qingqing's state, "How do you feel? Is the consumption of Qi a lot?"

"It's indeed a little bit bigger than simply controlling a handful of dragon scales, but I don't think it's a lot of effort." Luo gently felt the qi in his body and replied, "It shouldn't be possible to persist like this for an hour or two. question."

It seems that the potential of gas in energy conversion is indeed huge.

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 manifestations of spells, this is probably the most underestimated statement.

"The position of the sword has started to sink." Luo gently reminded him suddenly.

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

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

The next step is to mix the molten pig iron with the wrought iron as much as possible. If quality is pursued, the smelter usually uses huge iron tongs to hold the wrought iron sheet and roll it repeatedly in the molten iron to make the contact more comprehensive. This is essentially a helpless approach under the limitation of the furnace temperature. Xia Fan obviously has no such concerns. He relies on the dragon scale to further heat and melt the wrought iron with a melting point of more than 1,500 degrees. Both of them become molten iron. Naturally, Best blend ever.

This is the second step, and it is also a step beyond the times.

It represents the possibility of fast and efficient production.

Two quarters of an hour later, Luo lightly signaled that the blade would not sink anymore, no doubt the liquid level in the furnace had reached its lowest point.

Xia Fan nodded to Mo Yun and said, "It's time."

The latter took two steps forward and ordered loudly, "Get ready to open the furnace!"

"Yes! Open the furnace door!"

Pulled by more than ten people, the hemp rope pulled the heavy furnace door out little by little. Its length and width were less than ten inches, but its longitudinal distance exceeded an arm, like a plug to block the leak.

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

Under the huge pressure, even the ten-inch-long bottom made the scorching red flame rush seven or eight steps away.

Some people in the crowd started to cheer.

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

"Prepare for molding! Don't let the 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 quite some time.

Xia Fan went directly to the modeling area with Mo Yun, the princess and others.

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

Then he picked up a steel drill and smashed it several times against the iron sheet until silver-white gaps appeared on its surface.

After completing these two tests, the blacksmith excitedly reported to the princess, "Your Highness, Cao Min can guarantee with twenty years of experience that the iron produced in this furnace is indeed steel!"
