Since ancient times, talented people have been born in the Red Chamber

Chapter 438 This is the real skill of sharpening a knife without cutting firewood by mistake (second update)
Chapter 437

"In addition, we also need to carry out ore crushing and beneficiation. In this way, we can reduce the previous sulfur content to about [-]% of the past." Wang Yang explained with a smile.

"There is still so much sulfur? Can't the sulfur be completely removed?" Zhao Ji touched his chin and looked at Wang Yang with an expectant look on his face.

"There is no way. It is impossible to completely remove sulfur in large-scale industrial and large-scale production." Wang Yangxin said that steel in the 21st century will still contain sulfur. After all, this thing was originally used on a large scale and cannot be used. Is it required at the laboratory level?
With the strong support of Old Blacksmith Chen, on the sixth day, four hydraulic machines with excellent structures and made of metal and wooden structures were produced.

The hydraulic machinery used in the improved hydraulic printing press is the same model. All the places that need to be rotated are made of metal products. Not only in terms of durability and wear resistance, it far exceeds the direct use of pure materials. Wooden hydraulic machinery.

In addition, in the absence of synthetic lubricating oil, using animal fat as a moisturizer is also a very good choice.

There are two pulverizers in total, one is a sledgehammer type, which is specially used to deal with those large pieces of ore, and the other is a rolling type, similar to a water mill, which still uses cast iron rollers and discs.

The rollers and grinding plates alone consume thousands of kilograms of iron material. However, with these tools, the iron ore has been crushed into particles no larger than rice grains, or even smaller powders.

Then these ground mineral powders are poured into the conveyor belt, and after being absorbed by the magnet, they are sent to the other end from another conveyor belt through the scraper.

Several experienced old craftsmen squatted there, gently rubbing the iron ore powder with their fingers, watching Zhao Ji next to him anxiously. "How are you guys doing?"

"Young master, this iron ore powder is really too fine. We have never used it before. Moreover, such fine iron ore powder is not breathable at all. How to smelt it?" After discussing this, several old craftsmen gave Such an answer.

"Of course not. These ore powders also need to add a certain proportion of coke powder and limestone powder, then mix them with water, and then knead them into balls for firing..."

"Ah..." Everyone stared blankly at the commanding Wang Yang, thinking that this guy could have made a mistake, right?The ore blocks were obviously fine before, but you insisted on crushing them. Now that they are poured, you actually have to mix them and burn them again.

"Listen to me, don't worry, if something goes wrong, Wang will naturally take responsibility." Seeing the hesitant expressions of those old craftsmen, Wang Yang could only order forcefully.

There are many people and the strength is strong, and the firing of the mixture is completed quickly, and the mixture balls obtained are one and a half fist-sized balls. Originally, Wang Yang remembered that the smaller the better, but these people looked like bitter melons. For the sake of making it into such a spherical shape, it is still thanks to the creativity of His Royal Highness Duan Wang, who brought a

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

Time passed bit by bit, and Boss Wu, who was bored waiting, couldn't help asking whether the black tong pans that Wang Yang had sent to the smelting workshop one after another in the past two days were useful.

"Of course that thing is also used for smelting, but it is directly used for making steel instead of iron." Wang Yang explained slowly while drinking tea.

"Steelmaking?" Both Zhao Ji and Boss Wu raised their eyes and looked at Wang Yang who was drinking tea leisurely in front of him.

"Hmm, this steelmaking method is neither a steel filling method nor a steel frying method, but a whole steel ingot that is smelted directly using the raw smoke obtained from smelting and iron ore powder..."

"However, whether this technology is feasible or not will only be known after testing. Let's wait for the old drivers first, oh no, it is the result of the smelting by the old masters first."

"Sir, well, even if you say that you can pick off the solar energy from the sky, I can at least believe half of it. I really don't understand, brother, what else can you do besides giving birth and breastfeeding the child?" No." Zhao Ji said with admiration on his face.

However, in addition to admiration, there is another kind of expression called numbness. After all, the impact it brings is too much and too big for people to see.

"It's done, hurry up, scoop up the molten iron, the bastard over there hasn't prepared the mold yet... Hurry up, hurry up..." Just as the three of them were waiting drowsily, they suddenly heard an angry voice An old voice sounded.

Wang Yangteng stood up suddenly and walked quickly over there. He happened to see a strong man holding a spoon and pouring the molten iron into the mold nearby.

The molds were gradually filled one by one, and as the temperature gradually began to solidify from liquid, what appeared in front of Wang Yang and others were pieces of red pig iron ingots.

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

"High, it's really too high. Shopkeeper, look, this furnace of iron we smelted only produced so little slag, less than one-third of the previous one, and yet we produced so much pig iron. .” That old Liu head was so excited that he was a little incoherent.

"In the past, a furnace could produce up to 260 jin of iron, but now it seems that there is nearly [-] jin of iron more."

Naturally, someone next to me brought a large scale and weighed it at 350 kilograms of pig iron, which made everyone present smile.At this time, another old craftsman revealed another exciting news.

"In the past, a two-foot-high iron smelting furnace like ours could produce ten pieces a day, that is, about [-] kilograms of iron could be produced in one day. But now, the firepower of this coke is extremely strong, and the amount of iron produced is more than It used to be a lot faster.

The old man reckoned that there would be no problem producing 350 grades a day. If the pig iron of this grade is only 4000 catties, then calculated in this way, you can get [-] or [-] catties of iron a day, which is a total of [-] catties more. pig iron..." The old craftsman was indeed a veteran, and he quickly figured out the result.

Hearing this news, everyone couldn't help but gasped.

The stone in Shopkeeper Wu's heart finally fell to the ground, and he bowed deeply to Wang Yang in a sincerely convinced way. "You are really good, Mr. Zhuangyuan. In the past, when you were engaged in coking, ore crushing and beneficiation, Wu always felt that you, Mr. Zhuangyuan, were doing too much."

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

"As expected, he is indeed the number one scholar from Wenquxing. He is not ordinary." The blacksmiths all looked at Wang Yang with awe and admiration on their faces.

It's no wonder that everyone envies scholars. Look at the number one scholar. Sure enough, he really complied with the sentence, "Heaven and Earth, omniscient and omniscient. Even for smelting, he can think of these unprecedented methods. As a result, Suddenly, the daily output of Wu's smelting workshop directly stepped up to a new level in a lunge posture.
