Qin Er and Luo Dan are going smoothly, Deng Shifeng and Lao Sun Tou's infrastructure is also progressing well, because Deng Shifeng took out the grain to work for labor subsidies, and Luo Dan provided a lot of meat to stimulate it, and the food consumption seemed to be very fast, but the progress of the project was progressing slowly. Every day, the road leading to the mine is stretching forward, and the iron factory between the new village and the mine is being built little by little.

On the third day of the lunar month, entering the last month of the solar term of the year, the weather dropped to the lowest point of the year, coupled with the fine light rain for several days, the cold air made it difficult for the villagers in thin clothes to endure such a biting cold, in this weather Deng Shifeng also had to slow down the progress of outdoor work, so as not to soak the villagers' only clothes in the winter rain and cause a large number of diseases. Fortunately, the two-foot-wide roadway leading to the mine was basically completed, and the two-foot-wide trolley path was simply leveled or even tamped, and it is estimated that the two-kilometer sidewalk between the mine and the iron factory will become potholed under the washing of the water next year when the rainy season comes...... For this simple road, Deng Shifeng can only wait for next year's conditions, organize manpower to continue to widen the road and tamp the ground, and even pave a layer of gravel if possible to improve the traffic capacity of the road.

The inability to organize a large number of people to carry out outdoor labor has also slowed down the construction speed of the iron plant, but fortunately, due to the relatively full preparation of the previous organization, so far a large number of outdoor construction work has been basically completed, Deng Shifeng is taking the students to explain the structure of the blast furnace and the role of those regenerators on the spot in the past few days, while checking the final installation situation. Even a large amount of charcoal, the raw material for ironmaking, has been smoldered and entered the final stage of cooling, and even if the ironworks are unable to produce steel due to various unexpected factors, the people of the village can sell some of the charcoal in exchange for a small amount of supplies for the Chinese New Year. Although it is possible to build a small iron factory so quickly, although it is due to the guidance of later generations of travelers like Deng Shifeng, but more importantly, in Deng Shifeng's cave treasure house, there is such a set of key equipment such as crucibles and heat-resistant pipes in the small iron factory that has been used here, otherwise, just a crucible with qualified heat resistance is enough to postpone Deng Shifeng's industrial plan for a long time.

This set of equipment can appear here naturally has its origin, due to the development of the country in later generations, this kind of small steel plant with a few tons of low output and high energy consumption and heavy pollution, these small iron factories in nearby cities have been banned and closed down, but in many remote mountain nests, there are many such seriously polluted small iron factories can still survive, which has become the primary reason for low labor costs and weak supervision in remote areas, which is why this set of equipment just appeared in the mountains to transport an important reason.

(ps: Yimu is not from an engineering background, and even if he is from an engineering background, it is impossible to understand all the technologies involved, so it involves technical content, Yimu can only sacrifice the Spring and Autumn Period, and in the various crossing technology texts, there are already many detailed descriptions of how to engage in blast furnace and what drops. Note: If you really want to read the technical article, Yimu recommends Baidu a 07-year "Walking with Song", which is the first and only book that describes the technology more than the development of the story, and this chapter and part of the technology in this book quote the content of the book. The technical debate the book sparked at the time made the fiction review page more like an industrial technology discussion forum; As for the reason why it can't be found at the starting point...... Readers who have read it will know that even the practice of a certain acid and oil is detailed in detail...... ）

On the seventh day of the lunar month, this day is just an ordinary day for ordinary people, but for Deng Shifeng and the old grandson, they are unusual, today Deng Shifeng is going to take the students to burn the first batch of caustic soda. In addition to playing a certain role in steelmaking in the future, this batch of caustic soda is more important to take students to the door of the magical discipline of chemistry to appreciate its profound mysteries. Although the conditions are extremely simple now, there is not even a transparent beaker and test tube, and it is not very suitable to open chemistry courses, but Deng Shifeng cannot wait for everything to start developing chemistry and related education, because if steel is the father of industry, then chemistry is the mother of industry, without the support of a perfect chemical system for industrial construction, then no matter how great the degree of industrial development is, it is only a lame giant. Considering the huge role played by this important branch of the strategic jumping science tree in the future development, Deng Shifeng can only create conditions to open up under no conditions.

At the same time, it is also a good safety production process education in the process of burning caustic soda; The flame of high temperature, the quantitative configuration of the material, the accurate reaction time, the record of each step, the refinement to the personal work arrangement, all the process requires meticulous preparation and strict specifications in the implementation process, for these, the old grandson and their craftsmen and a few students promoted by Deng Shifeng are deeply convinced, and the farmers who came to help learn are not impressed, but when they heard that the furnace may explode and kill people, the disapproving faces of these farmers turned into expressions of fear, which can be seen, Even knowing that there is a certain danger, the curiosity of the craftsmen for the unknown is so great that there is a huge relationship between the traditional farmers. But fortunately, Deng Shifeng arranged to be responsible for the control of the main furnace and the recording and batching are all craftsmen and students who have been taught and learned, after a few weeks of surprise study, the students and craftsmen have basically learned the learning of 500 basic Chinese characters, these Chinese characters are the most common words used in basic conversation, because it is not too difficult to use and memorize often, but there are different degrees of difference in proficiency and mastery.

It is precisely because of a certain amount of education in advance, Deng Shifeng and strict monitoring and guidance on the side, the day's firing work ended without danger, and the students couldn't help but talk excitedly about the reaction changes during the firing process after finishing today's study, and some students even chased Deng Shifeng to ask him to tell more similar stories and principles; Deng Shifeng was very satisfied with the performance of the students, and at the same time explained and explained some of the principles and safety instructions of these chemical reactions to the students while the iron was hot, so that after stimulating interest, it is much more effective to instill knowledge when the students have the strongest curiosity than in the textbooks, and at the same time do not forget to emphasize the safety instructions for the preparation of various acids and alkalis and even more dangerous goods in the future......

Taking advantage of the momentum of this day's construction, Deng Shifeng continued to instill in the students and several craftsmen for two consecutive days the corresponding problems in the steelmaking process later, such as what is a co-solvent, with which limestone can be more easily melted into slag under high temperature conditions; What is good slag, there is good steel; The flow of slag will fully react with impurities such as sulfur, phosphorus, and silicon in the molten iron...... To be honest, even the smartest students with the best academic and strongest understanding ability can only understand only half-understood, Deng Shifeng didn't expect these students to be able to understand all of them now, he just asked the students to record these problems they don't understand, bring the problems to the upcoming work, learn on the job, understand and comprehend on the job. However, what made Deng Shifeng feel the most was that after the last exercise, the students had fully realized the importance of safe construction, and a more naughty student was burned off by a scorching fire, a handful of hair and two eyebrows, which made the students laugh and feel deeply afraid, in case they got closer...... It's not the eyebrows and the hair...... Such incidents have made the students particularly concerned about the upcoming steelmaking process norms and regulations, for fear of causing their own harm due to their own mistakes and violations.

A few days later, that is, on the eleventh day of the lunar month, after intensive indoctrination of relevant knowledge and repeated safety production awareness and various preparations, the first furnace of molten iron was happily poured out of the crucible, Deng Shifeng put the iron bar of the cooling test on the modified manual grinding wheel for grinding, and the splashing sparks told Deng Shifeng whether it was iron or pure iron-carbon alloy (that is, steel) that was refined. After talking to the students about how to pass the two components of the spark, that is, the difference between the bright line and the burst spark, the relationship between the carbon content of the steel is represented, as the samples of the second, third and fourth crucibles at different times are baked, and there are different identification samples of the burst and bright wire, the students finally understand the difference, and at the same time prove the success of Deng Shifeng's several different trial production of ordinary iron, medium carbon steel and low carbon steel products.

The success of liquid steelmaking made the old blacksmith even more crazy, the old blacksmith who had struggled all his life on the furnace and the blacksmith never dreamed that Daxian's ironmaking and steelmaking method not only made ironmaking more standardized but also reduced the consumption of manpower and carbon stone, but more importantly, the steel that he had to repeatedly forge and carefully made could be directly made into steel in this way!! The old man did not hide his emotions when he stroked the first batch of steel ingots, and his apprentice, who was his son, looked at the small blast furnace in front of him with bright eyes, wanting to see through the thick furnace wall, how the fairy called chemistry helped to make steel directly......

The success of steelmaking not only shocked the craftsmen of Lao Sun Tou, but also shocked Qin Er and many people in the village...... The great successes and examples made the last doubts in the hearts of the villagers disappear...... After the end of the day's steelmaking work, not only were the students enthusiastic about learning, but also the number of adults who listened to Deng Shifeng's evening class in the school every night and secretly learned to write in the field during the day...... Deng Shifeng naturally will not stifle the development of this phenomenon, he just secretly said in his heart:

"After seeing the ability of science to turn decay into magic, the enlightenment of wisdom and the future development ...... Finally really got started......"
