Iron ore mining is going on, and every day two truckloads of siderite are transported by Kodo block to the edge of the blast furnace site. Pen & Fun & Pavilion www.biquge.info

The production of charcoal could not keep up, and it became Yao Ran's heart disease with a little obsessive-compulsive disorder. After looking at the various methods in the system, the most reasonable method given by the system is the only way to expand the scale of production.

Yao Ran now does not have time to explore and find coal veins, the construction of the blast furnace has begun to dig the foundation, and the reserve of refractory bricks is completely enough to build the current blast furnace.

The construction of the entire blast furnace still needs Yao Ran's command and construction throughout the process, and there are more parts that need to be done by Yao Ran, and too many things can't be done. Yao Ran is now lacking in skills.

The construction of the blast furnace was carried out smoothly, and the surrounding scaffolding was used to make the whole blast furnace "grow" rapidly.

The throat of the blast furnace has been firing for a day and a night in the brick kiln where the refractory bricks are fired.

Yao Ran was following his apprentices to make a conveyor belt to transport materials to the blast furnace.

The same is the use of the power of the waterwheel, this time also used a gear drive conveyor belt, cast iron cast crawler conveyor belt, although there are gaps, but there is no problem in transporting iron ore, charcoal and limestone.

Sitting on Mu Dunzi, I watched a few apprentices sweating profusely, assembling tracks. On the other hand, he checked the work of his apprentices. This is because the entire track needs to travel a distance of 8 meters to make a round trip. The amount of cast iron used here has reached 800 catties.

And that's not even counting Yao Ran's latest cast iron pipe. Because of the heavy weight, there are a total of six fulcrums along the entire track. These six pairs of pointing are all used, and the hollow cast iron pipes cast by Yao Ran are competent.

After ten days of busy people, the conveyor belt was all built. The blast furnace was ignited three days before the construction of the conveyor belt was completed. After the heated air is blown by a blower, the temperature inside the skull of the blast furnace has reached 1,600 degrees Celsius. Such a temperature is enough to melt steel, and even refractory bricks will not be able to withstand it if it is 200 degrees higher. But this is already a temperature limit of the technology that Yao Ran used first, and if he can use higher-calorie coal, he may be able to increase the temperature by about 100 degrees.

1700 degrees Celsius is a reasonable value and a reasonable temperature for the refractory wall in the blast furnace. If maintained at 1800 degrees Celsius, the refractory wall will gradually begin to melt.

Yao Ran touched the head of the little gray gray, and the little gray gray also became a veritable little gray gray, and his head turned back to the dirty face. It's all caused by running back and forth with Yao Ran these days, haunting the edge of this stove and the edge of the charcoal pit.

Now the number of charcoal pits has been expanded by Yao Ran to five times, and the amount of carbon produced has directly increased to a huge value of 2 tons of charcoal per day. Of course, such a number is still far from enough for Yao Ran's ideal number. Yao Ran is also helpless about this, because the population is here, if this charcoal is turned into coal, it is a shallow coal vein, this number can be increased by several times, that is what Yao Ran wants.

In fact, it is not impossible to achieve, and the retinal system is running around the world, and the coal mine is still very easy to find. But capacity, manpower, and the size of Yao Ran's current tribe do not allow it.

So after a rational analysis, Yao Ran decided to sit down and honestly cut down trees and burn charcoal.

On the day the conveyor belt was built, Yao Ran did not immediately open the conveyor belt to transport various raw materials to the blast furnace. Instead, they rested on the spot and turned on the furnace to make iron at noon every day.

Yao Ran untied his clothes under the service of several wives, washed away the mud on his body with warm boiling water, and finally went under water on the bed, and after falling asleep, Yao Ran muttered, "Add some more charcoal." The temperature inside the furnace is not right. If there is too much iron in this basket, the temperature in the furnace will decrease. ”

Yao Ran, who had never worked so devotedly, was still thinking about blast furnace ironmaking after falling asleep.

After waking up the next morning, Yao Ran came with a large group of people, on the construction site in front of the blast furnace, all the high-level people in Yao Zhai also came to Yao Ran, in front of the tap of the blast furnace, a small bucket car made of four small iron wheels, iron frames, and clay has been parked.

Of course, this bucket truck is used to connect the molten iron, and once the molten iron is produced, a large number of molds on the right side of the open space are neatly and reasonably placed on the side. Yao Huo and Xiaoping were in charge of supervising the infusion of all cast iron products.

And Xiao Mumu also followed Yao Huo's side, this pair of happy enemies, they quarreled when they had nothing to do, but Xiao Mumu still listened to Yao Huo's words very much, because what Yao Ran said, Xiao Mumu often couldn't understand. All need to rely on Yao Huo to translate. So while watching Yao Huo, he often made Xiao Mumu unhappy, but the speed of learning did not fall behind at all.

And Lang Yan has been following Yao Ran's side. Although Lang Yan often doesn't understand what Yao Ran says. But Lang Yan has a good habit of asking if he doesn't understand, and asking again if he can't ask, until you can explain to me what I want to know. Otherwise, I will definitely keep asking.

Sometimes Yao Ran was stunned by some questions from Lang Yan. Although there is nothing wrong with asking questions, it is wrong for Lang Yan not to think about the process for himself. If you ask this question, I don't know how much you can learn from this question.

Therefore, after this blast furnace ironmaking, Yao Ran's final work will be placed on the education of the whole clan, of course, Yao Ran has also worried that when people's cultural level is generally improved, will they give themselves a liberal revolution. It's going to be miserable sometime.

Therefore, Yao Ran will not tell some mental skills, the things of the Emperor's Way to his own apprentices or anyone else. I can't even say about my own wife. Of course, Yao Ran felt that it was his wife who said it, and it was in vain.

Yao Ran felt that whether it was Xiao Jiali, Xiaoyu, or Ya and Xiaorui, in Yao Ran's consciousness, his wives were all hard-working children, and their desire for power was almost none.

So Yao Ran hugged left and right many times, lying on the bed, and talking nonsense with his mother.

When Yao Ran was thinking nonsense, Lang Yan beside him poked Yao Ran's arm and whispered, "Teacher, the sun is already noon, are we going to prepare for cutting and smelting iron?" ”

"Huh?? Yes???? Okay," Yao Ran said to Lang Yan and Hua Tuo beside him after coming back to his senses. "Alright, now let's start making iron. Today's first casting is our Yao Zhai, Danshu iron scroll. That is, our "First Statute" of Yao Zhai. (To be continued.) )
