Confirming that the arc rune plate can be used to make an electric arc furnace to smelt steel, Xia Lin once again came to Kyle's magic shop.

He needs to use the power of this group of alchemists to make the lid of the magic version of the 5-ton electric arc furnace he designed, and when the steel mill building and the electric arc furnace body are built, he can start smelting steel.

But when he heard Xia Lin's idea, Master Connie Kyle had a look on his face full of strange creatures.

"What's wrong, Master Connie? Can't I make this lid possible?"

"No, I was just wondering how the gods could have created a freak like you to design a furnace using arcing? It's a shame that you can figure it out, no wonder you were able to build that "Rune Variants and the Four Basic Rune Theories" that is as weird as yours.

Rest assured! You can make a lid, but it may be a bit expensive.

According to your requirements, the inside of the furnace lid must be resistant to high temperatures, and it must be able to channel demons, and I don't understand what it means to conduct electricity, but I think Adamantite can definitely meet your requirements!"

Master Connie took out a few pieces of paper and used a carbon rod to write and draw on them, and after a while, he looked at the results on them and nodded with satisfaction:

"Well, the lid you want will cost about 6.5 pounds of pure gold, which is 611 gold lundes, plus our manual fees and other material costs, even if you have 650 gold lundes!"

"650 gold lund?!

」

Xia Lin was taken aback by this terrible number, but when he thought about it, it seemed that only Adamantite was the only way to meet his requirements.

But this is not good, even if he thinks that he is not short of money, he will not be able to take out this money for the time being.

"650 gold is not much, and in order to work fine gold, I have to go to the president of the blacksmith guild.

It would be difficult for me to carve forty arc rune arrays on the lid of a furnace that is no more than two large ars (about 3 square meters), and at the same time adjust the parts of their inlaid magic stones to the same place to achieve the graded activation effect you need, and if it doesn't sound interesting, I don't want to take this commission from you!"

Master Connie tapped his fingers on the drawings on the table, emphasizing how difficult it was for him to realize Xia Lin's vision.

"The president of the Blacksmiths' Guild? You mean Master Holguin Copperbeard? Could it be that even an alchemist like you has not mastered the art of working with fine gold?"

Xia Lin asked in some surprise when he heard Master Connie's words.

"Oh? So you still know Master Holguin? Then maybe I'll be able to reduce the price for you by one or twenty gold lundes.

But how can pure gold be as easy to work with as you think? I've mastered a process.

But compared to the methods that have been handed down since ancient times in the dwarven clans, the materials consumed are too precious to almost equal the value of pure gold, and the effect is not as good as that of Master Holguin's methods."

Master Connie glanced at Xia Lin in surprise and shook his head to deny his claim.

It turned out to be the cost reason, it seems that Master Holguin's fine gold processing technology is really rare, Xia Lin thought, and then thought of his magic electric arc furnace lid problem.

Since the main cost of the electric arc furnace lid is pure gold, he can consider replacing this part of the fine gold with other materials, but after thinking about it, Xia Lin found that there is no metal that can achieve the effect of pure gold.

Mithril, which is cheaper than Adamantite, has extremely high magic conductivity, but its hardness and stiffness are much worse than that of Adamantite, which is almost non-wearing, and its melting point is much lower than that of Adamantite, so it is likely that it will not be able to withstand the high temperatures produced by electric arc furnaces.

The most commendable advantage of Mithril is the ability to obtain memorability through a special processing method.

In other words, the Mithril armor made in a special way will automatically repair over time even if it is damaged, which is very magical.

After discovering that this path would be a huge dead end, Xia Lin finally changed his mind and decided to overturn his previous design of carving a rune circle inside the furnace lid, and adopt the design of carving a rune array on the outside of the furnace lid and adding a layer of insulation material on top of it.

As for the current generated by the rune array, it is introduced into the electric arc furnace through the adamantite electrode, so that the cost will be greatly reduced, and there is no need to consider the thermal insulation of the rune array inside the furnace lid.

Later, after I found natural graphite and successfully made graphite electrodes, I could replace these precious gold, which was also expensive.

Thinking of this, Xia Lin nodded secretly, took out a pen and paper, and began to draw the new structure of the electric arc furnace lid.

Master Connie watched with great interest, as an alchemist, a craftsman among magicians, he was also very interested in Xia Lin's novel way of making pictures.

Soon, Xia Lin drew a drawing of the new magic version of the electric arc furnace cover, and he pressed the drawing on the table and handed it to Master Connie:

"Master Connie, look at the furnace lid of this structure, you don't have to worry about the high temperature resistance of the magic circle, and you don't need to consider the problem of magic conduction, you only need a column-shaped pure gold, how long does it take for the rune array on it to be made? How much will it cost?"

"Hmm...... Is that so? I think it should be done in 13 days! With just this bit of pure gold, it will cost about 120 gold lunds!"

Master Connie took the drawings and looked at them, giving an approximate time and budget.

"Whew...... That's good, then let's sign the entrustment contract! The time can be relaxed to fourteen days, and then I will send someone to pick up the goods!"

"No problem!"

Master Connie nodded.

With Master Connie's permission, Xia Lin finally solved the problem of the electric arc furnace lid, but this was only a part of the electric arc furnace, or even only a part of the furnace lid.

He then had to use refractory bricks and steel to create the electric arc furnace itself, as well as the part that was combined with the lid produced in the alchemy workshop.

In Xia Lin's design, the main part of the furnace lid carving rune array is made of magic copper, and the furnace cover made of magic copper has no thermal insulation effect, so at that time, Xia Lin's finished electric arc furnace will be an ordinary furnace body, plus a three-layer furnace cover.

From top to bottom, this three-layer furnace cover is divided into three layers: the insulation and control layer, the working layer and the thermal insulation layer of the furnace cover, in which a pure gold electrode runs through it, which is used to direct the current generated by the working layer into the electric arc furnace.

When the time comes to start smelting steel, you only need to put the pig iron, wrought iron and lime purchased from the market into the electric arc furnace in a certain proportion, and start the electric arc rune circle, and the current generated by the ten to forty rune circles can enter the furnace body along the pure gold rod, and use the high heat of the high-energy arc to melt the iron inside.

The subsequent slag making and slag removal process is nothing special, but the conditions are limited, and Xia Lin is only ready to add limestone as a desulfurization and dephosphorization agent.

There are no other deoxidizers such as aluminum, silicon, ferrosilicon, and iron ore for steelmaking, so the performance of steel can only depend on the quality of pig iron and wrought iron in the raw materials.
