The preparatory work of the blast furnace must continue, and now the firing of refractory bricks has been on the right track, but there are more follow-up work, such as the pipeline for transporting hot air, if there is tin foil that can keep warm in the air supply pipeline, of course, there is no problem, but there is no material, so you can only settle for the second. Pen ~ fun ~ pavilion www.biquge.info

Ceramic pipes are fired from clay. And semi-buried in the ground, the previous wood mold has been polished and made by Yao Ran, and the most important thing for firing the pipeline is that there can be no trachoma, otherwise the air leakage will not achieve the effect, and there may be unstable air pressure and gas reflux.

So for this work, Yao Ran has to check it personally, of course he doesn't do it himself, the person who does it is, of course, Yao Ran's little apprentice, Jin Ping's classmate. According to Yao Ran's requirements, Xiaoping surrounded the wooden model with clay in his hand, and always paid attention to the thickness of the pipe wall. When I do it myself, I focus on simplicity and practicality.

So busy an afternoon Xiaoping, only to make five pipes, if the firing of ceramic pipes, there is a 20% breakage rate, the first time to make such a strange product, I believe the success rate will be lower, but because the firing time is relatively long, so today's results can not be checked.

Xiaoping was already able to make ceramic pipes by himself, and when he was calcining in the furnace, Yao Ran ran to the side and began to study how to make a core component needed for a blower, the impeller.

Yao Ran prepared to make a wooden blower based on the existing materials. The main material is pine among hardwoods. Fortunately, the primeval forest is on the edge of the local materials, and the wood that the two of them hug abounds. Take local materials, find a large tree directly through the retinal system, and then take people to cut it down directly.

Take out the part of the tree core, cut it into a circle, and it took Yao Ran nearly half a day to polish it, divide the core of the 50 cm diameter basin into 8 equal parts, and then make a flat slot on every two symmetrical points.

After the center circle is done, take the wood chips, according to the culture and science of the annual rings, use a small stone chisel, little by little to plane out the leaves that are 50 cm long and 30 cm wide, and get nearly 20 in one go.

And then it's time for docking. After fixing the blade on the center circle, Yao Ran found a bamboo with the thickness of a baby's arm and more than three meters long, passed through the origin of the center circle of the impeller, and after the wooden wedge was fixed, the blade began to rotate clockwise.

If the impeller is installed in the blast chamber, the air duct is used to provide pressurization, and then the preheating furnace is used to increase the temperature of the air supply, it is believed that the hot air can be perfectly transported to the entire blast furnace to heat the blast furnace.

In this way, the impeller was already ready, and Yao Ran put the finished impeller into a temporary shack.

By the time Yao Ran came out of the shack, it was already dark. Originally, I wanted to select a site to make a waterwheel to provide mechanical power supply for the entire blast furnace.

Yao Ran, who was dressed in stars and moons, sat in his own unique sedan chair, and left two apprentices, one playing with mud and the other stacking blocks. The slaves ate and worked, and Yao Ran was also relieved of the quality of everyone's work, mainly because his two apprentices were more at ease.

After dinner, Yao Ran found Wei Jin, took Wei Jin and Wei Shui, and began to explain how to use wood, tree bark, animal skins and other materials to make paper.

This lecture lasted for nearly half a night, and one spoke until midnight, and the person who listened to it was mentally abnormal, showing that the baby who was waiting to be fed was absorbing Yao Ran's milk, but Yao Ran was not so comfortable, and he was sleepy for days.

The next morning, Yao Ran was listening to the work reports of the captains in the square, Wei Mu came over through the crowd, stroked his chest and saluted: "Patriarch, I pulled back 20 carts of wood." ”

Seeing that Wei Mu was back, and also brought back twenty truckloads of wood, Yao Ran stomped his feet excitedly. I'm really sleepy and send a pillow.

"Good, good, very good. Wei Mu, you have worked hard. Yao Ran said three good words in a row and nodded. looked at Lang Mao and the others, and said, "Lang Mao, you will give priority to selecting 10 carts of wood for building a house, and return more and make up for less." Lang Mao said yes.

Yao Ran turned his gaze to Wei Jin and Wei Shui again. opened his mouth and said: "Wei Jin and Wei Shui are going to get five truckloads of materials and pull them away." The porters are in charge of my slaves here, and when you send someone to follow me, I will leave the remaining five carts of timber useful. ”

Yao Shi and Yao Bone can continue the previous process of building the city wall, anyway, he is not very short of wood there now, and Yao Hemu is still guarding the salt pond and drying salt on a large scale. Fortunately, salt reserves have already begun to appear. It's not a state of how much you use in the sun.

"The people who applied for housing yesterday are waiting for me there today, and they don't apply to go back to live and wait, and the family will allocate a place of residence. Okay, let's do it today, let's go get busy," Yao Ran smiled and said, half of the 30 houses were occupied, and there were only 10 families who signed up to live, and Lin Lin and his son were among them.

The people who live in it either have put a lot of effort into this house, or they don't understand anything, they like to take advantage, and they don't know the importance of bamboo sticks. People who think they owe a few bamboo sticks don't matter.

After arranging a series of work, Yao Ran took the lead in leaving with everyone, and when passing by Lang Mao's side, Yao Ran said: "Let your family Langyan also come and learn from me." Lang Mao was stunned at first, and then turned to great joy.

Yao Ran was also thinking about the fact that there are not many available people around him last night, if he doesn't cultivate education now, there will only be fewer in the future, his cheap father-in-law, and cheap brother-in-law, can be used, and according to Yao Ran's observation, although Lang Yan is not as smart as his other three apprentices, but he is steady, and such people are more rigorous. Even if you give him the work and he doesn't do it well, there won't be much of a mistake.

It is precisely because of the lack of these trustworthy and capable people that Yao Ran would not let his guards and knights do these jobs. There is no way to let Wei Jin and Wei Shui help them get the paper out, after their first furnace of iron is practiced, and then make a point and a half, ink is not a difficult thing to get, they are printing a batch of banknotes, and the future issuance of money will be printed with their own pads. That's the money printing game of brushing.

When he arrived at his own construction site, Yao Ran checked the situation of the refractory brick kiln, the internal vision ability of the retinal system, and reported the various data in the kiln to Yao Ran very clearly, including the finished product time, the current precautions, his gold finger is really getting better and better, and this kind of do-it-yourself food and clothing is not comparable to those who come to open their mouths and stretch out their hands, and the full sense of achievement is full of Yao Ran's little confidence.

Looking at the pipes burned yesterday, on the periphery of the cave, the retina system reminds that the first batch of finished products has been completed and can be removed with tongs. I don't have any tongs. It would be good to just take out the big bamboo pole, so Yao Ran took Lang Yan and Xiaoping. After sweating profusely, I finally took out all five pipes.

Yao Ran was also stupid, and there was no damage, so Xiaoping sat on the side and continued to make the pipes that were not finished yesterday. Now that more than a dozen air supply pipes have been made, Yao Ran sat on the ground by himself, while Lang Yan stood beside Xiaoping and watched where Xiaoping made the pipes. All kinds of precautions, as well as the difficulties of production technology, Xiaoping answered them one by one, and he was also very patient.

Xiaoping's every move was seen by Yao Ran, even if this kid pretended to be in front of him, he was very satisfied, and when he was a teacher in the future, he would give his apprentices and grandchildren, Jin Ping, this kid, I am afraid that he will not be able to run.

The reason for making so many ventilation ducts is that the ducts are very short, and because the ventilation ducts are broken and replaced with spare parts. It seems that there is no need to live here, and the warehouse is a thing that needs to be built immediately.

The wood that Wei Mu pulled back, just at this time, sent it over, Yao Ran immediately greeted it. There were many people in the morning, and Yao Ran didn't show too much of his intimacy with Wei Mu. There weren't many people around at this meeting, Yao Ran stepped forward and patted Wei Mu's shoulder, Wei Mu looked at Yao Ran with worry in his eyes, and said, "Patriarch, the ...... on your back"

"It's okay, if you make a mistake, you have to bear it, can you still not bear the mistake because you are afraid of this pain?" Yao Ran looked at Wei Mu with a smile and continued: "You don't have to go to your heart, the two of us are brothers who share hardships, if you have a heart disease, otherwise you can lie down and let me give you a few strokes." ”

Wei Mu's eyes lit up when he heard this, and he said, "That's okay!" You're just going to give me a few strokes, and I'm comfortable! ”

Yao Ran listened to the black line at one end, and a chestnut knocked on Wei Mu's head. "You biao, you said it's okay, don't make me angry." After the fight, he smiled again: "Don't make trouble, let's get down to business, the work of timber transportation can't be stopped, and the rest of the timber is not good to collect." ”

"It's good to collect, and the trees cut down in the riverside village are all put together. The dragon trampled on trees everywhere. It can be pulled several more times. Wei Mu answered Yao Ran's question seriously.

Yao Ran patted him on the shoulder and said, "Good luck, then you don't need to go and run." Wei Mu first nodded habitually, then was stunned for a moment, and said, "Don't you need me to transport wood?" ”

Yao Ran nodded and said, "Well, I have more important work for you to help me do." ”
