Chapter 436

For these things arranged by Wang Yang, Zhao Ji's face was full of incomprehension, but the more this happened, the more Zhao Ji's curiosity was aroused, and he really wanted to see what these things Wang Yang got had to do with smelting steel.

Early the next morning, Wang Yang first rushed back to the yamen, communicated with Na Tushan, and asked him to supervise the renovation and construction of the royal street, while he himself waited for Zhao Ji in the yamen, and the two rushed to the Wu smelter outside the city.

After arriving at the Wu smelting workshop, the two sides signed the previously agreed agreement. After another greeting, Wang Yang began to look at the area along the river of the Wu smelting workshop.

In the steel smelting of this era, it was already known that the use of blowers made the firepower more vigorous, but most of them were manual blowers, of course, there were also a small number of hydraulic blowers, and the Wu workshop benefited from being built right next to the riverbank.

So three hydraulic blowers were installed, but one of them went on strike because of a breakdown, and the work started after the broken parts needed to be replaced.

"Boss Wu, you can keep this vacant land for me first, and in addition, including the hydraulic blower, will also be handed over to Wang, who is going to make some machinery that can make our smelting workshop produce better steel."

"Could it be that what kind of ore crusher you are talking about, and what kind of hydraulic concentrator is there?" Boss Wu smashed his mouth and muttered faintly in his heart.

Although it has always been his dream as a small businessman to be able to join forces with the champion, he just signed a contract, and he looked like he was going to make a big leap forward, which really made him feel a little uneasy, for fear that Wang Yang would have some problems.

Wang Yang nodded. "Yes, didn't Wang say it before, the grade of our iron ore is too low, if you want to increase the iron content and minimize the impurities in the iron ore, you need to crush the ore to the greatest extent first, and then rely on the hydraulic concentrator for beneficiation......"

"This, these machines, I'm afraid they will cost a lot of money?" Boss Wu hesitated with some distress.

"It doesn't cost a few dollars, don't worry, three or five hundred guan can be used, but the income in exchange at that time can't be exchanged for tens of thousands or even hundreds of thousands." Wang Yang saw the distressed look of this goods, and patted this guy on the shoulder, which was regarded as cheering him up.

What Wang Yang has to do is to get the hydraulic machinery out first, and the ore crusher is very simple, it is similar to the kind of hammer that smashes stones, and then uses hydraulic facilities to make the hammer automatically smash up and down, a hydraulic machinery is enough to drive seven or eight iron hammers to smash up and down, and below, it is directly used the kind of cast iron platform, that is, the iron felt used by blacksmiths to make iron.

After smashing, the scrap will be automatically swept down by two wooden sticks driven by hydraulic power, fall into the front funnel, from the funnel directly into the pit that receives the ore, and then the workers will shovel out the ore that has been crushed for the first time, and through the bamboo basket screening, the large particles will continue to be thrown down from the upper inlet, and those that may leak through the bamboo basket will be moved to the next process.

It is a hollow cylinder made of cement mixed with magnet powder and solidified, the surface is polished to a very smooth surface, and the iron powder in the mine is adsorbed on its surface.

After the iron ore powder is adsorbed at the bottom, after turning to the top, the iron ore powder adsorbed on the surface will be scraped off by a fixed scraper, and then transported to the other side through another belt......

If you want to accomplish this, you must ask the old blacksmith Chen to go out and create those suitable tools, whether it is rotating bearings or fixing parts such as screws.

However, it takes time to complete all of this, at least five or six days, and on the other hand, the coke oven has taken less than two and a half days to take shape.

Wang Yang asked those craftsmen to only pick up fist-sized pieces of coal, not too big, and too small. After picking out nearly 1,000 catties of coal, all of them will be neatly stacked in the coke oven. And then on top of the coals, the lime was evenly scattered.

The reason why lime is used is because lime is originally a very good desulfurizer, and Wang Yang is not a professional engineer, but he learned from those craftsmen that they will mix a certain proportion of limestone when smelting ore.

Thinking that it was also for desulfurization, Wang Yang simply used the stupidest method to directly wrap all the coal blocks on the lime powder, so that a large amount of sulfur could be adsorbed.

Then, it is to start ignition, and the next thing is to control the temperature, add or subtract coal, although Wang Yang is not an old driver of coking, he has his own means: bimetal thermometer.

The strips hammered together with mild steel and brass are set in a ring and then rested at the furnace mouth, where the scale can be calculated according to the change in the temperature of the furnace mouth.

As long as you repeat the test several times, you can know the approximate degree of bending and the temperature of the furnace mouth. And Wang Yang still remembers the description of flame and temperature in an interesting extracurricular book.

It is the relationship between the color of the flame and the temperature, for example, the dark red flame is about 600 degrees, the dark red is 700 degrees, the orange is 1,000 degrees, and the pure orange is 1,1100 degrees, the golden orange is 1,200 degrees, the golden yellow is 1,300 degrees, the golden white is 1,400 degrees, the pure white is 1,400 degrees, and the white blue is more than 1,500 degrees.

It took four days of hard work, and after scrapping nearly 5,000 catties of coal back and forth, I finally got the kind of coking coal full of holes and metallic luster that Wang Yang had seen in later generations.

And what Boss Wu and the blacksmiths in the workshop are curious about is that this kind of coke, which has been roasted for so long, can really provide a higher temperature?

Wang Yang did not hesitate to directly take out two hundred catties of finished products for testing. And the experienced old craftsmen, with the heat and the blue-white flame that they felt, came to the conclusion that the temperature of this thing was probably much higher than the temperature of the bituminous coal used in daily life.

And the moment he saw the blue and white temperature, Wang Yang breathed a sigh of relief in his heart, the high temperature of more than 1,500 degrees was definitely not running.

And after watching those wrought iron pieces were thrown onto the fire, they turned red and softened at a rate of more than one-third of the past time, and the snorts of Boss Wu and a group of craftsmen became heavy, and their eyes were swishing with golden light.

And Zhao Ji, who had been jumping up and down with Wang Yang for several days, looked a little sluggish, and his eyes were full of little stars at the moment, and he was worthy of the amazing Mr. Wushan, who actually let him get out.

"Sir, with this coking coal, is it possible to reduce the sulfur content by a lot?" Zhao Ji watched the soft iron bar being clamped out and thrown to the side, steaming hot, and couldn't help but ask Wang Yang.

"Well, I guess I can reduce the amount of sulfur by about fifty or sixty percent." Wang Yangxin said that there are no test strips or reagents or anything, I know a yarn, but in any case, it will definitely be reduced a lot.
