In the following days, Jia Yi devoted himself to the blast furnace, and in addition to checking the progress of the five-person group every day, he was building supporting facilities for the blast furnace.

The construction of the blast furnace, at least the construction of the iron-making blast furnace, is not as complicated as Jia Yi imagined, especially with the cooperation of the five mages, the construction is even simpler. If it weren't for Jiayi's high requirements, the main part of the blast furnace would have been done a long time ago.

Now, however, the main part of the blast furnace is nearing completion.

Jiayi is now doing the auxiliary facilities of the blast furnace, the blast furnace needs to be fed, blast, in order to improve the thermal efficiency, the wind drummed in is best hot. Therefore, Jiayi circled the air duct of the air inlet around the blast furnace, and the air was heated by the residual temperature emitted by the blast furnace before entering the blast furnace. In addition to this, Jiayi also designed a dust accumulation device at the chimney mouth, which can absorb harmful substances such as sulfur in the exhaust gas and purify the exhaust gas.

In fact, it is just a small blast furnace in Jiayi, which has limited pollution to the environment, but after all, he has been influenced by environmental protection, and since it is within the scope of his ability, he is still willing to do some measures to minimize pollution. Because of magic, the purification of exhaust gas is not difficult, especially the purification circle invented by Jiayi and Teacher Yimu based on activated carbon as a reference, and the purification of exhaust gas is even simpler.

Although this has increased a lot of costs, Jiayi feels that it is acceptable, but he makes a little less money, and it is not a loss. Although I just mentioned that the cost of industrial production is actually very important. In order to reduce the losses, he absorbs sulfur from the exhaust gas and produces sulfuric acid, which is preserved. The ore here is high in sulfur, so enough sulfur can be collected to produce sulfuric acid. Sulfuric acid is a relatively common solvent in alchemy, and it is finally somewhat useful, but the amount is too small, it is better than nothing, and it is more comforting.

The iron ore here only contains sulfur, not pyrite.

Originally, he also wanted to collect excess heat at the chimney where the exhaust gases were discharged, and then use it to boil hot water supply, so that he could take a hot shower at any time, and provide heating later, but this would have to make a tap water supply system, which was too cumbersome and gave up. Anyway, after he did it, he didn't live here himself, so he didn't bother to do this.

Chester looked at Jiayi busy making the supporting facilities of the blast furnace, and couldn't help but sigh: "I can't imagine that it is so troublesome to make iron, I used to see people making iron just take the furnace and add carbon to melt it together." Jiayi, are you worth it?"

Chester was a little amazed at the complexity of this iron-making blast furnace, which was not much more complex than some ordinary magic arrays, and in terms of architecture, it was the first time he had seen and participated in it—although the mage tower was a hundred times more complicated, he had never built it.

Especially for the air inlet, he couldn't understand why it was designed like this, going around the top of the blast furnace before entering the bottom air inlet. The blower connected to the waterwheel turned out to be a flower-like thing called a "paddle" by Kaichi, pushing the wind horizontally, not vertically. In particular, between the waterwheel and the blower, there is a huge gear set composed of many gear structures, which is called a gearbox by Jiayi.

All this was a novelty for the five, some of whom they could understand and many who could not. The most incomprehensible thing is why it takes so much effort to build this blast furnace, is it purely for money, as far as they know, Jiayi's net worth is not low, especially the working capital, and the kings of some small countries may not have as much as him. Theoretically, maintaining his current size would be enough for him to complete his studies.

Jia Yi said: "When you start moving, you will know whether it is worth it or not, and the efficiency is definitely different, at least more than a thousand times." ”

"Shhhh A thousand times?" Jasper on the side happened to hear it, gasping for air, he has a lot of life experience, and he knows more about the output of steel, how can he hear a thousand times this increase, he can't believe it at all, this is enough to change the pattern of the continent.

This thousand-fold is actually Jiayi casually said, but it will only be less, not more. The traditional method of ironmaking, at the end of a day, can have more than ten or twenty catties of output is not bad, the quality is not good, it is called sponge iron, to remove impurities after forging, and Jiayi's blast furnace, no matter how low the version, the output of 10 tons a day is not much, this is a thousand times. However, in general, the mine will not have only one small furnace to make iron, at least ten or twenty furnaces to make iron together.

Jasber whispered: "Jiayi, this output, if it is made into a weapon, can quickly arm hundreds of thousands of troops, and it is not difficult to rewrite the pattern of the continent." ”

"Don't worry. Although Jia Yi was also a little worried, he immediately left it behind, "If you want to rewrite the pattern of the continent, any purple-robed mage can do it, not to mention the legendary mage, that is, a matter of one sentence, I am nothing." Besides, you don't think that anyone can learn this blast furnace, and if it weren't for your help, I don't know when I would have been able to do it. ”

Jasper thought about it for a while, and it seemed that it was right, Jiayi's blast furnace was really not as influential as having a mage break through to the purple robe level, that was absolute force.

"But your concerns are not unreasonable, this blast furnace will always be discovered in the future, I have to make some camouflage for it, and when the time comes, it will be said to be a magic blast furnace, the cost of 300,000 starts, so that they can't even learn the mind. ”

"Will anyone believe this? What fool would draw 300,000 yuan to build an iron-making thing, and will the cost be recovered? March on the side said.

Jia Yi said firmly: "You don't know this, in the eyes of ordinary people, what the mage does not need a reason, the cost, the mage never cares about the cost." ”

It seems that everything is perfect, and possible problems are found and solutions have been found, but Kaichi always feels that there is something wrong that he has not thought through. It's just that he thinks that there must be a road in front of the lane mountain, and if there is no road, he uses magic to open one, so he ignores it.

Another half a month has passed, although the summer has passed, it has entered the September dew, but the temperature is still very hot, and Jiayi's blast furnace was finally completed, and a waterwheel was built, connected to the hydraulic forging hammer, originally he wanted to be connected to the original waterwheel, but the original waterwheel was connected to the blower, in order to avoid the dry period of power is not enough, can only build a new one.

Some time ago, the first furnace was opened to make iron, but some problems were found, and then Jiayi stopped the blast furnace to continue optimization. In fact, there is no problem with ironmaking, but if Kaichi wants to be more perfect, he probably won't build a second blast furnace, at least not in the short term, so he doesn't want this blast furnace to leave any shortcomings.

In fact, it is still a problem of exhaust gas, Jia Yi originally collected and filtered the dust and sulfur in the exhaust gas, thinking that it was enough, but he didn't want to hit the exhaust gas There is a large amount of carbon monoxide in the exhaust, this thing is toxic, he is afraid that it is dangerous to be directly discharged into the air, and he originally wanted to collect and make it into fuel, and make it into a gas tank, but it seems unrealistic to think about it for a while, the requirements for the gas tank are too high, and it will be miserable in case of explosion. If the pressure is too small, there is no point.

So in the end, Jiayi gave up his whimsical idea, collected the exhaust gas, filtered out the dust and sulfur components, and then mixed the exhaust gas with the hot air that was originally to be fed into the blast furnace, and introduced it into the blast furnace for secondary combustion to increase the temperature in the furnace.

Don't ask how it's done, even if it's not scientific, but there's magic.
