The four of them came to the front hall, the guests and hosts sat down, and Lu Yinchang instructed the housekeeper to get food and rice.It seems that the relationship between him and Li Tianyu is already familiar with each other.Walking from the backyard to the front hall, Wang Shuo's mind gradually cleared up.After a slight pause, he said to Li Tianyu: "Master Li cares about agricultural production, researches machines to increase production, and alleviates the hardships of farmers, and his spirit is commendable. ”Li Tianyu's old face turned red, and he smiled dryly: "The general praised it, Li Mou is ashamed" He has this thought, but Qinghai is barren, lacks fresh water, and the climate is very different from the inland.Recently, I have been obsessed with mathematics and physics taught by Wu Langxi, and it can be said that I am a little out of business.Wang Shuo continued: "Master Li's thinking is right.If we want to develop production, we can't rely on manpower alone, but also on science.Qinghai lacked fresh water, and Master Li wanted to build a vertical water wheel to bring water from the well up to irrigate the fields, which was a good idea.But in the next consideration, there is no need to be so troublesome, Europe has pressurized water firefighting appliances, as long as you make a pressurized water truck. ”Wu Langxi interjected: "We have also considered this, but the suction pipe of the pressurized water truck is too short to reach the well water.If the suction pipe is made long, the wood will not be able to withstand the pressure, and it will not work. ”Wang Shuo smiled: "Of course, the suction pipe made of wood is not good, you can use an iron pipe instead of wood." ”Wu Langxi looked at Li Tianyu, Li Tianyu looked at Wu Langxi, and then said to Wang Shuo: "The general laughed, where to find such a long iron pipe According to Li, there is no such thing in the world." ”Wang Shuo said: "There is no such thing in the world, but that doesn't mean it can't be done.Iron is heated to a temperature where it can be easily deformed, and then drawn or rolled to produce such thin, hollow iron pipes. ”Seeing that Wu Langxi was about to speak, he stopped him with a smile and said: "You must have a lot of questions for me, for example, how to get such soft iron, what can have such a great power to pull iron into iron pipes, this requires special knowledge, specialized people do it, as long as you do it, you will get it one day."
Let's talk about iron first," he asked Wu Langxi, "With your current knowledge, how do you make iron?"
Wu Langxi has long been unable to hold back, because these things mentioned by Wang Shuo seem to be feasible, but from his professional point of view, it is not feasible at all, it is simply a fantasy Hearing Wang Shuo ask himself, he hurriedly replied: "I currently know that the best way in the world is to melt iron ore with charcoal, and then after the iron is precipitated from the iron ore, it will be constantly stirred to get softer iron."
After this iron is condensed, it is heated with charcoal, then forged, and so on many times, and then put in oil to cool quickly, and make the best weapon, which is currently the best Damascus steel in the world.As far as I know, Chinese steel is nowhere near as good as Damascus steel.Iron is also impuritous, very brittle, and cannot be extended into iron pipes at all. ”Wang Shuo retorted to him: "This is what you don't understand yet.Iron ore is refined with charcoal, the temperature of charcoal is too low, how can you get more and better iron, why not use coal with a higher temperature You must say that there are too many impurities in coal, and you can't make good iron at all.Then why don't you want to think about it, change the coal, make it as less impurities and higher temperature than charcoal" Wu Langxi was stunned for a moment, and asked for a long time: "How to change" Wang Shuo smiled: "Crush the coal into powder, wash it with water, and then burn it like charcoal, and finally get it called coke, and use him to make iron ore, you will get better iron."
Moreover, the current iron-making furnace is not good, it is too short, it is necessary to increase the furnace chamber, use the wind to blow the wind, so that the carbon component in the iron is fully oxidized, and other stones and other things must be added as a filter agent, and finally the pig iron with less impurities can be obtained.Then, whatever kind of iron or steel you want, you can use this pig iron to refine it. ”Wu Langxi was completely stupid, just the matter of coal turning into coke was enough for him to ponder, Wang Shuo also said a lot of things he had never heard of, and he felt that his head was directly insufficient.As for Li Tianyu and Lu Yinchang, the two of them looked at him in a daze, not knowing what to say.Seeing that everyone didn't speak, Wang Shuo said: "I just want everyone to understand that the knowledge in this world is endless, and there is a lot of knowledge that we don't know and don't grasp in every direction and every specialized business.Therefore, relying on the two of you to hold back in the study, even if you want to break your head, you can't get much.If you want to get more knowledge, you must get more people involved, just like the seminary where Wu Langxi studied, many people learn and master what they already know, and many people, like Galileo, study and explore the knowledge we don't know yet, so that human beings can progress, and the kind of iron pipe I am talking about will eventually be made. ”:
