Chapter 436

For these things arranged by Wang Yang, Zhao Ji's face was full of confusion, but the more so, the more his curiosity was aroused. What does steel have to do with it.

In the early morning of the next day, Wang Yang rushed back to the yamen first, communicated with Tu Shan, and asked him to supervise the renovation and construction of Yujie Street, while he himself waited in the yamen for Zhao Ji who rushed over, and the two Together they rushed towards Wu's smelting workshop outside the city.

After rushing to Wu's smelting workshop, the two parties first signed the previously agreed agreement.After exchanging pleasantries, Wang Yang began to inspect the riverside area of ​​Wu's smelting workshop.

Iron and steel smelting in this era has already known that the use of blowers makes the firepower more vigorous, but most of them are manpower blowers, of course there are also a small number of hydraulic blowers, and Wu's workshop benefits from being built next to the river bank.

Therefore, three water-powered blowers were installed, but one of them stopped working due to malfunction, and the broken parts needed to be replaced before work started.

"Boss Wu, you should keep this open space for me first. In addition, the hydraulic blower is also handed over to Mr. Wang. Mr. Wang is going to make some machinery that will allow our smelting workshop to produce better steel." Come."

"Could it be the ore crusher you mentioned, or the hydraulic concentrator?" Boss Wu smacked his mouth, muttering inwardly.

Although it has always been his dream as a small businessman to be able to form a joint stock partnership with Mr. Zhuangyuan, but this Mr. Zhuangyuan just signed the contract, and he looked like he was about to engage in prostitution, which really made him feel a little uneasy, for fear that Wang Yang would do something. The question comes.

Wang Yang nodded. "Yes, didn't Wang say before that the grade of our iron ore is too low? If we want to increase the iron content and minimize the impurities in the iron ore, we need to first process the ore to the maximum extent. crushing, and then rely on hydraulic concentrator for mineral processing..."

"Are you going to spend a lot of money on these machines?" Boss Wu hesitated with some distress.

"It won't cost much, don't worry, three to five hundred guan can be spent, but the income in exchange will not be exchanged for tens of thousands or even hundreds of thousands of guan." Wang Yang saw this product With that distressed look, he patted the guy on the shoulder as a way to cheer him up.

What Wang Yang has to do is to get out the hydraulic machinery first, and the ore crusher is the simplest thing, it is similar to the hammer that smashes stones, and then use the hydraulic facilities to let the hammer move up and down automatically, one by one. A hydraulic machine is enough to drive seven or eight hammers up and down, and the cast iron platform directly used below is the iron felt used by blacksmiths to make ironware.

The crushed material will be automatically swept down by two wooden sticks driven by water power, and will fall into the funnel in front, from which it will fall directly into the pit where the ore is received, and then the workers will crush it for the first time. The ore is shoveled out and screened through the bamboo basket, and the large ones will continue to be thrown down from the upper feeding port, while those mine ends that may leak through the bamboo basket will be moved to the next process.

It is a hollow cylinder formed by mixing cement and magnetic stone powder and then solidified. The surface is polished very smooth, and the iron powder in the mine will be adsorbed on its surface.

After absorbing the iron ore powder 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 passed through another belt and transported to the other side...

Thinking about accomplishing this, old blacksmith Chen must be dispatched to make suitable tools, whether it is rotating bearings or fixing parts such as screws.

But all of this takes time, at least five or six days to complete all the work, while on the other hand, the coke oven took less than two and a half days to take shape.

Wang Yang asked the craftsmen to only pick coals the size of a fist, neither too big nor too small.After picking out nearly a thousand catties of coal once, all of them would be neatly stacked in the coke oven.Then, on top of those coals, lime was evenly scattered.

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

Thinking that it should also be for desulfurization, so Wang Yang simply used the most stupid method, directly wrapping all the coal lumps in lime powder, so that a large amount of sulfur could be absorbed.

Then, it starts to ignite, and the next step is to control the temperature, add and subtract coal. Although Wang Yang is not an experienced driver of coking, he has his own means: a bimetal thermometer.

The strip after combining mild steel and brass hammer is embedded in a ring, and then rested on the furnace mouth. According to the temperature change of the furnace mouth, the scale can be measured.

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

It is the relationship between the color of the flame and the temperature. For example, the dark red flame is about [-] degrees, the deep red is [-] degrees, the orange is [-] degrees, the pure orange is [-] degrees, and the golden orange is [-] degrees. , golden yellow is [-] degrees, golden white is [-] degrees, pure white is [-] degrees, and white blue is more than [-] degrees.

After spending four full days of scrapping nearly [-] jin of coal back and forth, I finally got the kind of coked coal full of holes and with a metallic luster on the surface that Wang Yang had seen in later generations.

What Boss Wu and the blacksmiths in Yiqian Workshop are curious about is this kind of coke that has been baked for so long, can it really provide a higher temperature?

Without hesitation, Wang Yang directly took out two hundred catties of finished products for experimentation.And those experienced old craftsmen, based on the rushing heat and the blue-white flame they felt, came to the conclusion that the temperature of this kind of thing is probably higher than that of the bituminous coal used in daily life. Even higher grades.

The moment he saw the blue-white temperature, Wang Yang breathed a sigh of relief. The high temperature of more than [-] degrees definitely did not run away.

And after seeing those wrought iron blocks turned red and softened at a rate of more than one-third of the past, after throwing them on the fire, Boss Wu and a group of craftsmen's noses became heavy, and their eyes shone with golden light.

And even Zhao Ji, who seemed a little sluggish after jumping up and down with Wang Yang for several days, his eyes were full of little stars at the moment.

"Sir, with this kind of coking coal, is it possible to reduce a lot of the sulfur content you mentioned?" Zhao Ji watched the limp iron bar being clamped out and thrown aside, steaming, and couldn't help it. Chao Wangyang asked.

"Well, about [-]% to [-]% of the sulfur content can be reduced." Wang Yangxin said that he didn't have any test paper or reagents. I know a lot of wool, but no matter what, it will definitely reduce a lot.
