Zero Ring's arc rune disk has a simple structure, consumes less energy, and can continuously emit arcs, and its power can probably easily electrify adults who touch it to shock, and the reason why Xia Lin bought them is to get a continuous and stable current.

Electricity, as the energy core of the second industrial revolution, has a very wide range of applications in industry, and electrolysis is one of them.

If it is confirmed that the high-energy arc generated by arc surgery can indeed be used for electrolysis, Xia Lin can even produce caustic soda instead of soda ash, but by electrolysis of saturated salt water to obtain caustic soda, chlorine and hydrogen, which is the so-called chlor-alkali industry.

In addition, electrolysis can also be used for electroplating and smelting metals, for example, tinplate is the product of tinning of thin steel sheets, which can be used to make cans, and galvanizing machine tool parts can also prevent hydrogen embrittlement and corrosion.

Metals such as potassium, calcium, sodium, magnesium, and aluminum can also be smelted by electrolysis.

There is another important thing that also needs electricity to participate, and that is electric furnace steelmaking, which smelts steel through the ultra-high temperature provided by the electric arc, which is the technology that Xia Lin wants to apply in the steel mill.

If he can use an electric furnace to make steel, the efficiency will definitely be tens or even hundreds of times higher than the crucible method he originally planned, and then the pig iron and wrought iron on the market can also be used to produce various key steel products, and maybe there will be excess capacity to sell on the market.

Because the existence of graphite was not found in the market of the imperial capital, and there was no news of the commission for the time being, Xia Lin connected two copper electrodes to the arc magic rune disk, inserted a saturated salt solution at the other end, and embedded the magic crystal on the back of the rune disk.

In Xia Lin's surprised gaze, after the rune disk began to take effect, there was a faint crackling static sound in the air, and in the solution of the clay pot, there was also a clear blue precipitation, and at the same time, there was a popping sound.

This is because the two electrodes used by Xia Lin are copper electrodes, which causes copper hydroxide precipitation at the anode, and hydrogen escapes from the cathode, which touches the copper electrode of the charging ***, and a small explosion occurs.

If it is all graphite electrodes, then the products will be sodium hydroxide, chlorine and hydrogen.

"It seems that the phenomena produced by the spell are exactly the same as those of nature."

With an excited smile on his face, Xia Lin came to this conclusion, and his thoughts had begun to radiate to think about the various industrial applications of spells.

However, before he could do that, he had to make sure that the cost of applying the arc rune disk to industry would not be too high, otherwise it would only be used on a small scale as a special means.

This is also simple, Xia Lin used a large copper electrode and a saturated salt water solution to design an arc rune disk energy dissipation experiment.

In the end, a magic crystal was obtained, which was about enough to support the arc for four hours, and the total mass of copper hydroxide precipitation obtained was 15 pounds, which is about 50 kilograms.

According to the measurement data accumulated by Xia Lin in previous experiments, the magic power of such an ordinary-quality magic crystal polished by a gem craftsman should be about 180 blocks, which means that the energy consumption of the electrolysis rune disk is about 0.75 blocks/n.

In this way, arc surgery still has a certain practical value in industry, at least in the application of electrolysis, it is absolutely no problem to use this method to produce some products.

The next step is to see if arc can be used to smelt steel.

Although Master Faun's high-temperature rune plate is easy to use, it is the secret of their clan, and only the priests of the molten fire clan with magical powers know how to make this extremely special rune plate.

When Master Faun became a slave, he also brought this piece with him, and it was later recovered from the slave chamber of commerce by the royal family.

Compared to the high-temperature rune disk that could not be reproduced for the time being, Xia Lin wanted to explore the application prospects of the arc technique by himself.

He came to the industrial park with these arc rune disks and magic crystals that served as energy sources, and urgently summoned a construction team to build a simple cylindrical kiln body with a diameter of two meters and a height of three meters with refractory bricks, and some small protrusions were piled up with cement inside.

Then let people put one hundred and fifty pounds of pig iron and wrought iron of the same weight in it, and use the hands of the mage first

Five activated rune disks were placed on the deliberately left bulge inside.

Standing on the herringbone ladder, Xia Lin could observe the surface of the iron gradually turning red in the jumping blue-white arc, and it was obvious that the arc of the arc could also produce high temperatures.

It seems that it is possible to use the temperature of the arc generated by the arc to make steel, but I don't know how many rune disks are needed to melt pig iron and turn it into molten iron, and how much mana in the magic crystal will have to be consumed to smelt steel.

Continuing the experiment, when the number of rune disks increased to ten, the pig iron finally began to melt into molten iron, which means that it only takes ten arc rune disks to act at the same time to produce a high temperature that is hot enough to melt steel.

The melting point of steel is around 1500 degrees Celsius, and it seems that it works to trade the amount for the energy rise of the arc.

The entire discharge heating process lasted for more than four hours, and Xia Lin used the mage's hand from time to time to adjust the position of the rune disks to prevent them from being destroyed by the high heat in the furnace, but even then there were three rune disks that lost their effect due to the high heat.

Eventually, the mana crystal embedded in the rune disk ran out of energy, and the rune disk stopped discharging.

In this way, Xia Lin can roughly estimate the cost and profit of using arc technology to make steel.

In the market, a heavy pig iron costs 3 silver mar 20 copper pes, a heavy wrought iron costs 7 silver mar 44 copper pes, and a heavy steel price is 16 silver mar, which has now risen to 20 silver mar.

It takes about half an hour for the electric arc furnace to completely melt the three hundred heavy raw materials, plus half an hour of redox reaction time, ten magic crystals cost 20 gold lundes, which is almost enough to support four rounds of steelmaking.

Even if you design an electric arc furnace that is no more than 1 ton with electric arc technology, it can produce nearly 300 pounds of steel at a time, and it will be about 1500 pounds a day, and the New Leaf Chamber of Commerce will be able to earn about 150 gold lundes.

In this way, using the arc technique to build a magic version of the electric arc converter for steelmaking has considerable prospects, and after Xia Lin finished calculating these data, he couldn't help but have a happy smile on his face.

Faced with this result, the other onlookers were even more surprised, and Master Faun shouted with surprise on his face:

"Boss, have you cracked our clan's rune disk?"

But he then shook his head again:

"No, our rune disks don't produce these crackling lightning bolts, and they melt steel much faster than yours!"

"Master Faun, do you use a lot of mana on your rune plates?"

Hearing Master Faun's words, Xia Lin, who had just finished calculating the cost and output of this rudimentary electric arc furnace, also became interested in his rune disk.

Although smelting four furnaces of steel does not cost ten magic crystals, it is still quite curious about the energy efficiency of the rune disks made by the priests who have mastered the mysterious magic power among the dwarves.

"I don't know much about this, but there's nothing wrong with refining dozens of heavy steel from a single magic crystal.

Now that I have lost contact with my clan for a long time, I usually don't dare to use this rune disk at will.

I wouldn't have taken it out if it wasn't for the need to make the machine, but this is a skill that every member of our Molten Fire Clan needs to swear to keep secret when they can pick up a hammer!"

Master Faun said with a wave of his hand.

"Is that so?"

Seeing that Master Faen cherished that rune plate so much, Xia Lin also extinguished the idea of borrowing it for research for the time being, mainly because he didn't have much time now.

However, if you think that the high-temperature rune disk constructed with the flame rune, a variant of the kinetic rune, can directly convert mana into heat, it is more efficient than your own arc rune disk, which converts mana into electricity and then heats it through arc heat release.
