After painstakingly "pondering" for a few days, Lin Wushuang proposed to see how iron was smelted in this era, and it seemed that he remembered something.
This matter is very easy to do, Shuntianfu five prefectures and nineteen counties, on the Changping side, there is a large mine, and the Creation Bureau has its own yamen there.
Mining and smelting are quite large-scale, although it is said that the Ming Dynasty has a monopoly on salt and iron, and it is natural that idlers and others will not be relied on, but if a certain guest of Dingyuan Bofu wants to go and see it, this is naturally no big problem.
If the young lady of Uncle Dingyuan personally brings someone over, then no one will say anything, and people who don't stammer on weekdays are willing to come to you to take a look, that is their own creation. chose a sunny day, and the group took a turn in Changping, and Lin Wushuang knew it in his heart.
"How's it going, Mr.
Lin?"
Qian Ningji, who didn't talk much all the way, finally couldn't hold back on the way back, "This mine, the smelting furnace or something, I have this rule in the Ming Dynasty, see that Mr. has not said a word, isn't it different from the smelting utensils of Mr.'
s house?"
"It's not different, it's just the same" Lin Wushuang saw the smelting blast furnace, and became more and more sure that his local method of steelmaking has a big market, which is also called the blast furnace to listen to the craftsman who can smelt hundreds of catties of pig iron a day, which is quite a remarkable achievement, if you keep improving, according to the level of steelmaking, this daily output has a few dozen catties of steel is good, this efficiency, it is better to find a group of blacksmiths, directly forged out of steel.
Of course, the blast furnace just now must not produce any steel, he is very sure, the temperature can not reach it at all, even if the smelter has used coal as fuel, but the combustion value and the coke used in modern smelters are not at all.
All in all, after this field trip, the inspection is still a representative official smelter, he is very sure that this strange dynasty, the smelting technology is far less developed than he imagined, of course, this also proves on the side why a few small pieces of stainless steel, will be the eldest lady of the Qian family, who is said to be rich, in his heart.
"How many catties of pig iron can the Ming Dynasty produce every year," Lin Wushuang thought for a moment and asked.
"I'm not an official of the Ministry of Industry, how do I know" Qian Ningji rolled her eyes, "However, I think, there are always millions of catties."
"What about the steel mother," Lin Wushuang continued to ask.
Qian Ningji hesitated for a moment, and said with some uncertainty, "There are probably tens of thousands of catties."
Lin Wushuang converted it, and suddenly felt that this Qian Ningji was a bit nonsense, such a big empire, with only a few dozen tons of steel output a year, no one would believe it "Then where are these steel mothers generally used," Lin Wushuang smiled slightly.
"Part of it is probably to be dedicated to Ouchi, casting all kinds of weapons, rewarded by the Son of Heaven to the courtiers, part of the Creation Bureau and the Ministry of Works, and used in the casting of firearms, which is the greatest use, and then the last other part, probably also the generals use swords and swords or something, well, it should be like this" "These things are not allowed to be bought and sold by the people."
"Of course, but you don't have to worry about this, even if you come up with this method, you will eventually have to sacrifice it to the court, but who will give it to the court, it's just a little different."
"I do have some ideas, but this method, dedicated to the court or not to the court, it doesn't mean much, even if this method can be used, the court can't afford it" Lin Wushuang passed the information he got last night in his mind, and his thinking became very clear, "How did our family refine this steel mother, after looking at today's smelting, I was right, perhaps, this method can be used" "It's a lot of money" "It's very expensive" Lin Wushuang nodded, "It's unrealistic to think of such a large-scale smelting as the imperial court."
Lin Wushuang calculated very clearly, the soil method of steelmaking, of course, is a method, if the Qian family does not care about the cost, if they have a mine, they can use it, this is very simple, like the scale of smelting seen today, he put forward some suggestions for improvement, change the fuel to increase the temperature of the blast furnace, build the blast furnace with better refractory materials, and turn the manual operation of the blower into a hydraulically operated blower, etc., this series of measures, although it is very troublesome, but there are always some results, which can be explained.
The other is to use the information given to me by the wormhole, a graphite crucible steelmaking method that has not yet appeared, using the smelted molten pig iron in the graphite crucible seal and heating, so that the graphite and the molten iron react at high temperature, deoxygenation and impurities, so as to obtain purer molten steel.
Obviously, the second method is much simpler than the first method, however, without the first method, the second method cannot be carried out, and what is even worse is that even if it is the second method, the output of this steel will not be very high.
In Lin Wushuang's heart, if the Qian family did not have high requirements for the number of "steel mothers", he really planned to use this method to come out.
Of course, if it is a hammer deal, it is better to say, no matter how he communicates with the wormhole, he will always persuade them to send a batch of modern steel from the wormhole, this is the simplest and most direct way, but Lin Wushuang easily did not dare to use such a method, this wormhole, inexplicably from being able to people to pass through, has become now only the size of a football, who dares to guarantee that it is not a time when he comes out with something to break this wormhole, perhaps, this wormhole teleportation has a limit on what mass and weight, He had no idea.
In the past few days, there has been some paper information exchange on the other side of the wormhole, maybe it is not a big problem, if this kind of large-mass transmission is carried out, this wormhole will collapse and disappear directly, then he will really stay here in this ancient world and live here honestly for a lifetime.
Under the premise that no one gives guarantees, Lin Wushuang will never take this risk with his last retreat.
"You have to get it out first" Qian Ningji thought for a while, "It is always useful to be able to refine some more steel mothers, Mr. doesn't have to think about it so much, as long as this method is useful, even if it is not used temporarily, if you know more about it, you don't know how good this method is" "That's good" Lin Wushuang nodded, "Go back and write down the things I want to buy for the eldest lady, let's give it a try" aa2705221 t1706231537:
