Yao Ran followed behind Xiaoping with various moods, and it was really a diversion of attention that helped relieve the pain. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 info The current Yao Ran completely ignored his injuries. Until Xiaoping stood still.

Yao Ran stood in front of the limestone mine, and in the distance was a large number of slaves digging the limestone mine with big sticks and bamboo tubes in their hands.

Xiao Ping pointed to a small pit on the ground and said:

"This is where Hua Tuo fell! I just dug up the rocks here! ”

Yao Ran looked at the soil on the ground that was still slightly humid, yes, it was obviously a newly dug pit. Xiaoping doesn't need to lie to himself. Because now Xiaoping doesn't know what an important gift he brought to Yao Ran, which is comparable to a great gift.

Yao Ran took a deep breath, but his slightly trembling hands still betrayed Yao Ran's inner excitement. But the two people around him couldn't see it, and thought it was caused by Yao Ran's injury.

There is not much to say about the importance of iron ore to a society, at this moment Yao Ran slowly raised his hand, Yao Ran does not need to be like an exploration team, does not need to be based on geomorphological characteristics, and does not need to analyze according to soil. As long as the retinal system scans the data, it will automatically appear in front of you, and the finger and ring finger of your right hand press down on the temple, and the scene in front of you is very different from when you found the limestone vein here before.

The large amount of limestone that originally covered it, showing a white cloud-like layer, has disappeared, and instead of it, the black-gray iron ore is marked and the black iron ore vein has been extended in the direction of the alpine belly, and the attached table also has detailed data, siderite, iron ore grade average 45. Total ore vein content: more than 17 million cubic meters.

“Areyoukiddingme？ Why didn't I find out? Yao Ran popped out a sentence in English, and the system returned according to the user's request, the system detector, blocked by the limestone vein, could not continue to measure and detect the unstable signal in detail. Limestone veins have a great influence on the detection signal of the system, so it is not possible to detect iron ore veins located at deeper depths.

After getting the answer, Yao Ran did not feel any unhappiness because of the lack of discovery last time, but became more and more excited, "Is siderite grade 45 iron-rich?" The system was asked again and the system was presented with a list of data.

Siderite is relatively low iron content in other iron ores but the recognition is very high, because the gap between other stones in half a life is obvious, so that a lot of time is saved in the beneficiation, and the iron-making process of siderite is simpler than hematite, and magnetite, the process is simpler, and the process requirements are not high, and the temperature can reach about 1000 degrees after drying into the furnace.

Yao Ran had already begun to study how to make iron, Yao Ran was squatting on the ground and writing and drawing on the ground, was he still muttering in his mouth, his left hand was on his left temple, and his right hand was holding a wooden stick and drawing on the ground. A stove that looks like it's a lot longer.

There were more and more pictures drawn on the ground, and finally Yao Ran stopped painting, and one by one the paintings were drawn on the ground with Yao Ran as the center in a circle. Give Yao Ran a surround in the middle. There are also various symbols written on the ground. Yao Ran squatted on the ground and muttered: "Coke, charcoal, ore, blast, slag discharge, furnace throat, what is the blast pipe made of?" Yao Ran said to himself.

The two high-ranking apprentices were looking at the picture drawn by Yao Ran on the side, discussing what their teacher was going to do, Yao Huo said: "It should be a new way to burn bricks." ”

"I don't think it's, it should have something to do with the stone I found, but I don't know what exactly it burns, there are still a few small holes here, is this going to be buried in the ground?" Xiao Ping frowned and touched his chin and said.

"I don't think it's buried in the ground, you see there's a winch here. It should be something that turns and then drives the rope. It is a transmission of power. Yao Huo said with some pride.

Xiao Pingleng paused for a moment and then asked, "What the teacher taught you?" Tell me what it's for. The transmission of power? What does the transmission force do? ”

is grinding Xiaoping with a face of showmanship, Yao Huo who is now learning and selling. Yao Ran suddenly stood up and began to walk in the direction of Yao Zhai. The two apprentices also hurriedly followed in person. One left and one right supported Yao Ran, because he didn't walk in a straight line.

Yao Ran's mind is now full of how to make iron and how to make steel, several key technologies Because of the encyclopedia of the retina system, Yao Ran's contact with these things that he has never been in contact with has become relatively simple, in fact, to put it bluntly, Yao Ran makes a blast furnace according to the requirements of the drawings in the retina system.

The principle of the blast furnace is very simple, that is, after the iron ore is crushed, it is put into the high-temperature blast furnace at the same time with charcoal or coke, and then heated by the furnace throat and enters the melting zone, and the flame at the bottom of the blast furnace continues to heat the molten iron appears, but the high-temperature molten iron is also accompanied by residue.

The slag agent is used as limestone. Both the molten iron and the blast furnace slag flow out into the iron car in a liquid state. Or it can be directly drawn into iron bars for forging, or casting. Of course, casting requires molds. The production of molds is very close to refractory bricks, and the use of high-temperature firing ceramic molds is Yao Ran's first choice at this stage.

There are naturally ways to use and make iron. But what is needed now is to make a blast furnace to make iron. A blast furnace is needed for iron smelting, and the first step in the construction of a blast furnace is the need for refractory bricks. Refractory bricks are actually mainly made of clay after calcination. This member of the Yao clan in the high mountains already has a wealth of experience.

In the process of ironmaking, due to the defects of materials and energy, only charcoal can be used now, and there is no technical difficulty in burning charcoal. Just need a lot of wood, just before the giant dragon dinosaur has given itself a lot of raw materials as long as they are transported back, but the efficiency of the blast furnace can only reach 2000 kilograms of charcoal out of a ton of iron, and the cost-effectiveness ratio is very low. Limestone has a large reserve and does not need to be mined in particular.

The pre-mining stage of siderite is not difficult, and the front section of the veins explored by the retinal system is almost on the surface, and some of the previous veins are excavated less than 1 meter above the ground, and a large amount of excavation is not a problem. Now it is the construction of the capital that needs Yao Ran to be busy.

At this time, Yao Ran turned around and saw that his two students had been supporting him. "Hey, what are you doing? Oh yes, Yao Huo hurry up, I'll make the crane I painted for you. If 10 days is enough time for you, I will help you supervise, give you the technical director, and which Xiaoping, I will teach you a new technique, you can write words and pictures on it, you can keep it for a long time, and you can pass it on. I'll give you five days to complete this job. ”

Yao Ran thought for a while and continued, "You help me go back to the family house, and I will draw a drawing for Yao Huo with the animal skin." Make it according to the drawings. By the way, I will teach Kodaira about papermaking techniques. ”

Yao Huo was elated, and Xiaoping didn't know what papermaking was, so he helped Yao Ran in a daze, thinking along the way that he had come into contact with a lot of things today, but they were all in the clouds.

Back to the family house Yao Ran began to draw the design drawings of the crane for Yao Huo again, what position of the materials, as well as the length and size of the materials, the total number of all are clearly written on a piece of animal skin, and still muttering while writing, how many angles with how long the platform support, if the platform is decisive, it will cause an accident of tilting and collapse, the reason is that because the fulcrum strength is not enough, you can consider adding boulders on the platform for stability, but it is only suitable for fixed lifting, If you want a displaceable crane, you need to add a movable stone tray at the bottom as a platform, etc. Then there is the material, length and force of the boom. Finally, there are the precautions for the production of pulley blocks.

Yao Huo, who had seen the general situation of the design drawings in the morning, learned even more about the past. It's just that Xiaoping heard a lot of questions for the first time and didn't know why, why increasing the pulley can make the lifted weight quilt, arm, and boom bear half of the force, and increasing the pulley block can continue to reduce the pressure, but Yao Ran, who has ironmaking in his heart, did not answer Xiaoping's questions.

Instead, he began to explain to Xiaoping how to make paper from wood, bark, hay and other materials. In Yao Ran's opinion, this is a work of great significance, but compared to the complexity of the machinery, Xiaoping prefers the crane, and Yao Ran's drawing of an extended version of the stove.

Yao Ran was completely immersed in his own world, and did not pay attention to the thoughts and performances of his little apprentice, but just said to himself: "The production of paper requires boiling and breaking the bark and trees, and then removing the black foreign matter, so as to keep the paper white and flawless. The process of breaking can make a batch of stone pounds. The beaten wood pulp is diluted, strained on a fine bamboo mat, and then dried in a cool place, remembering that it can no longer be ....... in the sun."

"Xiaoping, you're listening, what's wrong with you?" Yao Ran finally noticed that he was reading the cutting board of papermaking in the system, the simplified process. But one of his own listeners was studying the crane drawings he had drawn, and the audience he was mainly targeting was absent-mindedly watching his big apprentice studying the drawings.

Xiaoping heard the master's shout, and instantly felt a little embarrassed. Lowered his head and didn't dare to look at Yao Ran's eyes, Yao Ran was a little angry, how urgent I am now, I handed over such an important task to you, you still don't like to listen, I think you are a little ambitious. Papermaking is no more influential than being a crane.

Of course, Yao Ran didn't say these words, after all, Yao Ran is also a person who has done front-line sales and led a team, and interpersonal relationships are relatively good at handling, and those college students who have just walked out of school are all happy by themselves, not to mention these slightly smarter primitive people.

So Yao Ran asked, "What's wrong Xiaoping, don't you like this papermaking technique?" ”
