Chapter 44: Steel cement

　　"Of course, get the horse." After recovering, Xiao Ming exclaimed.
　　 The graphite mine was found, and the limestone mine was also found. Although the mine has not yet been established to form a systematic production, it is still possible to mine some in advance.
　　 It's just a part of mining, and Xiao Ming also costs a lot. The miners who mine and transport all need to give money.
That’s why Xiao Ming is so eager to cooperate with Liang Dahai this time. As long as there are a large number of slaves, mines, and workshops can have enough manpower, and then he will select some young adults from the slaves to transfer various technologies and gradually build The industrial base of Qingzhou.
　　 One master and one servant, the two went out of the Qi Palace and went to the Department of Equipment. Now, apart from going to the Dudu’s Mansion to supervise the implementation of various government orders, the most of this is going to the Department of Equipment.
　　In the Equipment Department, Chen Qi is correcting the production of the crucible steelmaking assembly line. The technology is available, but there will be deviations in the specific production practice.
　　 During this period, Xiao Ming has intensively trained Chen Qi, and Chen Qi has also received the most technology transmission in this technology spar.
　　 While other craftsmen often master certain specific technical steps, they can't fully grasp the entire process. The reason for Xiao Ming's doing this is very simple, that is to prevent the leakage of the craftsman's skills.
　　 Ten people mastering ten parts of a set of technology are more secure than ten people mastering all the technical processes.
　　Moreover, the Equipment Department has also formulated strict technical confidentiality measures. If anyone leaks the secrets, the craftsmen on the production line will be punished.
　　 In Da Yu, the craftsmen belong to low-ranking households, and their status is very low. In order to prevent craftsmen from making weapons privately, the household registrations of these craftsmen are individually made into craftsmanship and are subject to the supervision of the government.
　　 It is a very simple matter to control these people in and out of Qingzhou.
　　 "His Royal Highness, these are limestones." In the backyard of the Equipment Department, there are piles of gray-white stones, these are limestones.
　　In modern times, limestone is not only a necessity for cement production, but also a necessary solvent in blast furnace ironmaking. Limestone can effectively remove sulfur and silicon impurities, improve iron quality, and prevent subsequent refining of steel from becoming brittle.
　　 Xiao Ming took a look and found that these limestones were piled into a two-meter-high hill. The limestones are also relatively large and of good quality.
　　 Two blast furnaces are working at the same time. Four workers take turns using blowers to blow air into the blast furnace. Some craftsmen pour iron ore, coke, and limestone into the blast furnace.
　　 Red molten iron flows from one blast furnace to another blast furnace, and finally the molten iron flows into the crucibles assumed to be on a one-meter high shelf. When one crucible is full, the other crucible will be replaced by another crucible.
　　 This kind of efficiency is still a thousand miles away from modern times, but compared with the previous steel filling method, this is already mass production.
　　The formation of high-quality molten steel will be used by different craftsmen to build tillage tools, machine tool parts, and briquettes.
　　 Chen Qi is now guiding the workers to collect the slag, which Xiao Ming taught him.
Seeing Xiao Ming observing the steelmaking process, he wiped the sweat from his forehead and said, "His Royal Highness, you said I will collect this after adding limestone. Now there is a lot of this slag, but what's the use? "
　　 "This is a good thing, it can be used to produce a very powerful material." Xiao Ming smiled.
　　 Xiao Ming has not said this knowledge to Chen Qi, Chen Qi curiously said: "His Royal Highness, this is out, you can tell me, otherwise I might not be able to sleep at night."
Xiao Ming chuckled, "In fact, besides iron making, this limestone can also be calcined into a material-cement! Because the contains a large amount of cement, the can also be used to calcinate cement, so you can collect it. It’s not to waste it, otherwise it would be a pity to throw away the slag."
　　 "Cement." Chen Qi and Qian Dafu looked at each other.
　　 Now they are quite familiar with the strange words that popped out of Xiao Ming, and they don't know where the prince learned all these strange knowledge.
　　 Xiao Ming and the two stood aside, and the knowledge in the technology spar was instilled in the two people's minds. After explaining them, the two understood what cement is and what its function is.
　　 "His Royal Highness, if this cement is used to build city walls and pave roads, wouldn't it be invulnerable." Chen Qi said in surprise.
　　 "No, cement is only the most basic thing, and things made of concrete are really invulnerable." Then Xiao Ming told Chen Qi about the concept of concrete.
　　 "..." Chen Qi is now unable to describe his shock in words. He said: "His Royal Highness, if the walls of Dayu Kingdom are all made of concrete, then the barbarians can only be outside the walls."
　　 Xiao Ming smiled and said: "Now you have a lot of thinking. Although this concrete and cement are magical, it would be good if we can satisfy our own needs at our current production speed."
After a while of excitement, Chen Qi suddenly became a little bit decadent. He said, "His Royal Highness, you teach me too much now, but you see this equipment department, there are too few craftsmen, but this work has been exhausted, this calcined cement It's ~EbookFREE.me~ I guess there is no staff."
During this period of time, the Department of Equipment has recruited some craftsmen. The number of craftsmen in the Department of Equipment has reached fifty, but it is obviously not enough. He can't help but feel a little helpless. Just produce as much stuff."
　　 Chen Qi nodded helplessly.
　　 This time Xiao Ming came here, one is to check the application of limestone and graphite in ironmaking, and the other is to let Chen Qi learn about cement and prepare for subsequent production.
　　 As the saying goes, if you want to get rich, you need to build roads first, and traffic is smooth, which can greatly promote production, and because of the characteristics of people living in cities in this era, road construction does not need to be like modern times, which can be hundreds of miles.
　　 The application of crucible ironmaking has matured, but now the graphite and limestone mines are only in the hands of Xiao Ming, which is equivalent to his monopoly of crucible steelmaking technology.
　　 However, lack of labor is still his shortcoming, and the current equipment department is generally a trivial matter.
Thinking of this, he can only increase investment in Liang Dahai. Every year, the barbarians will plunder many people in the country of Da Yu. These people have become goods traded between the barbarians and the country of Da Yu. The barbarians engaged in the slave trade.
　　 For slaves, his first choice is naturally the people of Da Yu. As for the slaves outside the territory, basically they can only do some hard work, after all, language communication is also very difficult.
　　 Stayed for a while in the Equipment Department, and then guided the craftsman on the details of steelmaking before Xiao Ming and Qian Dafu returned.
