186 The combination of science and magic has good curative effect
Polu held a roll of scratch paper with sketches in his hands and walked out of the door of Landau's laboratory in a daze.
After all, it was really shocking to him to conduct experiments directly into the crater! Is this what a human being should do?
Looking at the description in the text, it seems that I stayed in the crater for several days! No matter how you think about it, the crater is a place full of high temperature, dust and poisonous gas! Is the protection so high?
Is it true that if one is strong, one can act casually?
The cold outdoor air rushed into his lungs along his trachea, making him sniffle, and then he came back to his senses from the boss's wanton experimental conditions.
As he walked in the wasteland, he thought about how to best apply the things in the sketch. The principle of this equipment is really magical - after all, the steel workers on Earth dreamed of being able to dissolve the hot water without adding anything.
A method to directly accumulate impurities in molten iron.
As long as the current state of the impurities dissolved in the molten iron is correctly set, there will be no problem even if it is dissolved!
The furnaces made in Hongshan are not particularly large in capacity. Basically, the three removals are carried out in the converter in the refining workshop - after all, the magic classification is terrifyingly powerful. The iron ditch is really only used to alleviate the problems caused by the furnace.
The impact force of the molten iron is flushed out and the slag floating in the molten iron is screened out. The later refining is fully capable of handling such small batch production!
This time, in Polu's expectation, he would get a stove that was not very tall, but relatively fat and had a large furnace space.
As for why the stove is getting fatter as it is made?
That's because there is no need for coke to provide heat, and less material needs to be piled in the furnace. At the same time, the magic flame is strong enough - this thing can be used nearly semi-permanently as long as it is invested once. What else can be said? Of course it is oversupplied!
As long as the stove doesn't burn out, it's done!
Charcoal is only used as a reducing agent, material column skeleton and to increase the carbon content in the whole process. At first, I was worried that there was not enough charcoal, so I asked the elves to get the seeds of the fast-growing tool tree. Later I discovered that if charcoal does not need to provide heat,
, in fact the required weight is not that much.
This actually made Polu feel a little relieved - after all, he was not sure whether these tool trees were still growing so fast on the island.
The number of energy-concentrating panels powering this furnace has been increased to 48. Plus a quarter of the backup number, there will be a dedicated area at the foot of the furnace body to erect 60 energy-concentrating panels.
These 60 energy-concentrating panels and the associated magic storage will take up a large area. It may be larger than the blast furnace itself. Just making them and connecting the magic will cost a lot of copper, especially since the furnace is not ready for construction at one time.
one!
Thinking about this terrible amount of copper makes Polu feel suffocated:
"On this island, there is a shortage of everything except iron and limestone! We must pay attention to going out to sea to find sources of minerals! I need ships! I need cheap steel suitable for mass consumption!"
In fact, there is no need to control the composition of mass-produced structural steel to this extent.
"I was a little stupid at the time, so I made all the elements that might appear in the ore, but in the end I found that there were only a few that could be extracted. An entire converter of molten iron could extract elements the size of half a meter.
If you want to say whether impurities are counted, they are indeed counted, but what impact does it really have? It is almost non-existent! What else to mention? Adding steps in vain is a waste of time. It took a long time to scoop it out, and all the spoons were used to stir it.
Burnt out."
Bolu laughed to himself in his mind.
"In the future, a batch will be tested and tested. If the quantity is reduced to this level, we will not mention it."
When the analysis process was not done before, there were times when the molten iron was cast into iron ingots and could not be hammered by manpower, and the forging hammer would directly break it. The most direct reason is that the carbon in the molten iron is too high - the higher the furnace,
The higher the efficiency, the charcoal added according to experience will not be consumed so quickly.
This hard and brittle cast iron can be used to make mortar shells, but forget it as structural steel - it's completely useless.
Instead of allowing the carbon to oxidize uncontrollably in the later stage, it is better to add less.
Although the converter used in Hongshan is so small that it looks like a molten ladle, it is technologically advanced - except for the spoon part, which is really advanced!
It can sift out the impurities in the molten iron very clean, and the mages like it very much. According to Zhu Yiwei: "Pure steel is very expensive! Ordinary people can't provide this. They can only provide us with iron ingots and let us
Purify it yourself.”
"No, why do you mages need iron ingots? Isn't this thing insensitive to magic power?"
"It's true that magic is insensitive, but we still use steel. When we use it to build large equipment, um, for example, to build a large shield generator bracket, is it really necessary to be as luxurious as pure mithril?"
"I don't quite understand, what factors need you to refine?"
"Just steel is fine. Some steel is mixed with a lot of other things. Some of the elements mixed in are sensitive to magic power, and some are not. In many cases, the same batch of iron ingots are different. They are used in large-scale
It’s really dangerous on magic facilities!”
Zhu Yiwei's face had the unique look of a programmer who had been working for three days but couldn't solve the bug:
"If you don't clean up these elements, there will always be some inexplicable problems. You don't even know where to look for them!"
"If we produce in large quantities, will Sing Tao buy it?"
"As much as you want!"
"As much as we have agreed upon!"
This good news made Boru suddenly excited!
Although the elements dissolved in the molten iron are by no means simple substances, it is really a bit complicated to set up classification, but the solution is also very simple, and it was already solved in Hongshan - use the classification array in reverse, so that
It only classifies iron and carbon, which is equivalent to an exclusion mode in disguise, just squeeze out elements other than iron.
After manual screening, you can get a very pure subway, so that if you want to improve the performance later, you have to separate the beneficial elements screened out and add them back.
This method can finely control the composition of molten iron!
After detailed records, Bolu has a good grasp of what kind of steel properties will be obtained by adding what elements.
But it was really a last resort to do this at that time, because at that time we had to make weapons, but now, we have to make a lot of ordinary structural steel, so it’s not a mistake to make it so clean!
But now it is impossible to continue this method. It is impossible to roll out production and just stare at the stove. There must be a way that does not require hard work every day, just change workers at will, and just rely on the process, so that you can be lazy, no, produce with peace of mind.
!
Bolu mentally went through the information he had accumulated when he was at Hongshan, and he had determined who was among certain impurities that had been screened out. Although he had not encountered rare elements yet, he could still recognize manganese and chromium.
.
As for phosphorus and sulfur, he designed another two-pronged approach.
When he couldn't solve the problem by using additives to create slag, Bolu decided to choose a physical solution! He thought about the magma tank on the sketch, and then thought about the appearance of the slag-blocking iron ditch that he had seen in the news, and an idea gradually emerged
forming.
"I first make a larger iron ditch, which is similar to this sketch. Once it comes out, I first add lime and then stir it. Then I let it pass through a sieve.
Several openings are left on the curved outer wall of the iron ditch, and a classification array is installed on the inner wall. When the iron water flows through, scum and impurities float on the iron water, and will be directly repelled by the array to the other side of the ditch.
Centrifugal force will naturally throw them into the slag ditch.
After the separated elements and scum are thrown out of the bifurcated slag ditch on the ditch wall, they will enter a separation tank and be separated again. The useful ones are kept and the useless ones are thrown away.
The volume of the crucible is proportional to the jar used to hold the molten iron. How much beneficial elements of the crucible are put into each molten iron package, and then stirred, you can get steel close to the proportion. It is controllable, but it feels
This is a stupid method and not very accurate."
He hesitated for a moment, as if to encourage himself again: "But compared to controlling the ingredients of slag making, the requirements for workers are much lower!"
