Chapter 437

"In addition, we need to carry out ore crushing and beneficiation. In this way, the previous sulfur content can be reduced to about 30% of the past. Wang Yang explained with a smile.

"And so much sulfur? Can't you completely remove the sulfur? Zhao Ji touched his chin and looked at Wang Yangdao with an expectant look on his face.

"There is no way, large-scale industrial large-scale production, it is impossible to completely remove sulfur." Wang Yangxin said that steel in the 21st century will still contain sulfur, after all, this thing is originally a large-scale application thing, and it can't be required at the laboratory level, right?

With the strong support of the old blacksmith Chen, on the sixth day, the four well-structured hydraulic machinery with metal and wooden structures were baked.

It is the same type of hydraulic machinery used in the improved hydraulic printing machine, and all the places that need to be rotated are made of metal products, not only in terms of durability and wear resistance, but also far more than the direct use of pure wood hydraulic machinery.

In addition, in the absence of synthetic lubricants, the use of animal fats and fats as a warming agent is also a good choice.

There are two grinders, one with a sledgehammer for large pieces of ore, and the other for rolling, similar to a water mill, still using cast iron mills and grinding discs.

Thousands of pounds of iron are consumed for the mills and pans alone, but with these things, the iron ore has been crushed into particles that do not exceed the size of a grain of rice, or a smaller powder.

The ground powder is then poured into a conveyor belt, where it is adsorbed by the magnet and then sent from another conveyor belt to the other end through a scraper.

Several experienced old craftsmen squatted there, their fingers gently rubbing the iron ore powder, and Zhao Jigan next to him was anxious. "Husbands, what's going on?"

"This son, this kind of iron ore powder is too fine, we really haven't used it in the past, and such a fine ore powder is not breathable at all, how to smelt?" After this discussion, several old craftsmen gave such an answer.

"Of course, no, these ore powders also need to add a certain proportion of coke powder and limestone powder, and then mix them with water, and then knead them into balls for firing......

"Ah......" Everyone looked at Wang Yang, who was in command, and said in their hearts, this thing can't be a mistake, right? Obviously, the ore block before was good, you have to crush the ore, and now it's good, and you have to mix it up and burn it again.

"Listen to me, don't worry, if something goes wrong, Wang will naturally take responsibility." Wang Yang saw the hesitant expressions of those old craftsmen, so he could only give a forced order.

There are many people with great strength, and the firing of the mixture is completed quickly, and what is obtained is a mixing ball the size of half a fist, originally Wang Yang remembered that it should be as small as possible, but for the sake of these people with two expressions like bitter gourds, plus making such a ball, it was still thanks to the creativity of His Royal Highness Duan Wang, and one was brought

Next, there was another long wait, and Wang Yang watched as the young craftsmen began to lay the materials, light the fire, and start smelting under the command of the old craftsmen.

Time passed little by little, and the bored Boss Wu couldn't help but ask Wang Yang what the kind of black tongs that Wang Yang had sent to the smelting workshop one after another in the past two days was useful.

"Of course, that thing is also used for smelting, but it is directly used to make steel, not iron." Wang Yang drank tea and explained slowly.

"Steelmaking?" Zhao Ji and Boss Wu both raised their eyes and looked at Wang Yang, who was drinking tea leisurely.

"Well, this steelmaking method is neither a steel-filling method nor a steel-frying method, but a whole piece of steel ingots smelted directly using the raw smoke obtained from smelting and iron ore powder......"

"But this technology, whether it is feasible or not, still needs to be tested to know, let's wait for those old drivers first, oh no, it is the smelting results of the masters."

"Sir, well, even if you say that you take the solar energy from the sky, I can at least believe half of it, little brother, I really can't understand what else you can't do except give birth to a child and breastfeed a child." Zhao Ji's face was full of adoration.

However, in addition to adoration, there is also a kind of numbness in the expression, after all, the impact is too big and too big, which makes people look away.

"It's done, quick, scoop the molten iron, the bastard over there, don't get the mold ready...... Hurry up and ......" Just as the three of them were waiting drowsily, they suddenly heard an old voice full of energy.

Wang Yangteng stood up suddenly, walked over there quickly, and just saw a strong man holding a spoon and pouring the scooped up molten iron into the mold on the side.

One by one, the molds were gradually filled, and as the temperature gradually began to solidify from the liquid, what appeared in front of Wang Yang and others was a piece of reddened pig iron ingots.

"How is it, old Liu Tou, is the amount of iron produced this time high?" The shopkeeper Wu also walked over and looked at the pig iron ingots that were still red.

"High, it's too high, shopkeeper, you see, the slag from this furnace of iron we smelt is only so little, less than one-third of the past, and it has smelted so much pig iron." The old Liu Tou was so excited that he was a little incoherent.

"In the past, a furnace could produce up to 260 catties of iron, but now it looks like there are nearly 100 catties of iron."

Naturally, someone next to him brought a large scale, three hundred and fifty catties of pig iron, which made everyone present smile. At this time, another old craftsman said another exciting news.

"In the past, our two-zhang high iron-smelting furnace could produce ten editions a day, that is, one day, about 2,600 catties of iron. Nowadays, the firepower of this coke is extremely strong, and the tapping is much faster than in the past.

The old man estimated that there would be no problem if he produced twelve editions a day, and if this version of pig iron was only 350 catties, it would be calculated that he could get 4,200 catties of iron a day, which was 1,600 catties more pig iron...... "This old craftsman is really a veteran, and he quickly calculated the result."

Hearing the news, everyone couldn't help but gasp.

The stone in Shopkeeper Wu's heart finally landed, and he bowed deeply to Wang Yang with a sincere heart. "Zhuangyuangong, you are really powerful, before, what kind of coking, as well as what kind of crushing and beneficiation, Wu always felt that Zhuangyuangong, you were doing too much."

"But now I know that this is really called sharpening the knife and cutting firewood."

"Sure enough, he is worthy of being the champion of Wenqu Xing, not ordinary." The blacksmiths all looked at Wang Yang with awe and admiration on their faces.

No wonder everyone envies the scholars, look at this champion duke, and really responded to that sentence, called heaven and earth, omniscient and omniscient, even smelting, he can think of these unheard of methods, as a result, Shengsheng made the daily output of the Wu family's smelting workshop directly step up to a new level with a lunge posture.
