Yang Yuanyuan said: "Isn't your lime not burned yet?"
"So? It's baked today. Where are the steamed buns?" Qin Jun asked.
"It has been prepared for you a long time ago. Come and eat! We have all eaten. We ate in advance because we all have to dig rocks in the afternoon."
Qin Jun was a little surprised when he saw that the white-noodle steamed buns brought out from the kitchen were not triple-noodle steamed buns at all.
When did his father become so willing to bleed? unusual!
"That's not all, is it? Eat them all for me?"
Soon, Qin Jun guessed the truth.
Needless to say, this steamed bun must have been brought by my sister-in-law from her parents’ house, and he ate it a lot.
Although I only taste a few bites each time, I can’t help but eat it so many times!
I haven't seen my two nephews and one niece in recent days. Needless to say, they must have gone to their grandma's house.
Qin Jun's expression became a little strange when he thought of what his sister-in-law had done.
It turns out that he really didn't pay attention and felt that the sister-in-law was normal!
But now that I think about it, where is it normal?
If in the future generations, everyone is Voldemort, his sister-in-law will be the one who preys on the old master.
In the 1970s, the gnalao clan was still very fashionable.
Not only did they eat their parents' food, but they also brought it home, and they really couldn't eat it and walked around!
This is not over yet, because it is cold at home, and every winter, it seems that several of his nephews have to go to their grandma's house to stay for a long time.
"When will my eldest nephew and the others come back?" he asked as he thought about it.
Yang Yuanyuan answered smoothly: "We will pick him up when the Chinese New Year is approaching."
This is a very reasonable statement. The three children eat until the Chinese New Year. This is really not caring about the food of the mother's family!
This Qin Zhihe is not honest. Is he using things from his daughter-in-law's natal family to deal with his son? Still don’t pay attention to him!
It’s really better to ask for others than to ask for yourself. At this time, if you want to eat well and eat well, you still have to rely on yourself.
Qin Jun has realized that his father is unreliable, and he no longer needs to count on him in the future.
In fact, he had already had an idea, and it was because of the burning lime.
Although you can't do business privately now, you can do it collectively.
He can't make all the money, so can he get some salary? Let’s solve the food problem by the way!
With the decision made, Qin Jun immediately felt hungrier!
He was never thick-skinned enough, so he just broke off a small piece and tasted it as usual, and asked his sister-in-law to put away the rest.
Holding half a fist-sized white-flour steamed bun, and taking out five or six pancakes from a wooden box at home, Qin Jun returned to the table.
After searching around, I couldn't find any vegetables, even pickles would do!
"Sister-in-law, there is no cooking at home today?"
Qin Jun was a little confused. It turned out that no matter how difficult the family was, he would still cook some food.
In the winter, it’s either cabbage or potatoes. Although it’s not delicious, it’s there. What’s going on today?
The sister-in-law came out of the kitchen again and said hesitantly: "Our father said you don't need vegetables to eat steamed buns!"
"Okay, I know, sooner or later, Lao Qin will regret it." Qin Jun almost laughed in anger.
If you don't want to eat, you won't eat. Qin Jun ate the pancakes with steamed buns and had a full meal.
At this time, he had decided in his heart that his father and son should also settle the accounts openly, otherwise, Lao Qin's calculations might become louder.
We haven’t crossed the river yet! I just want to burn bridges, but I haven’t even bought a house yet! Just pulling out the ladder, I can only say that Lao Qin's vision is a bit short-sighted.
After all, he is his biological father, so he can't be said to be short-sighted, right?
However, it may be a bit difficult to build a house for free in the future!
After eating, Qin Jun was more motivated. After all, he had to work hard and be self-reliant.
Thinking of some things that were not available, Qin Jun quickly made all preparations.
Although he has never used such crude tools as now, he is professional in steelmaking. After all, he was doing this for several years before his rebirth.
There was no other way. It was adjacent to Asan Kingdom, Badie Kingdom, Aqionghan and other countries. The black workshops where they worked never lacked business.
Making guns is the basis. Reloading the large and small flying monkeys and assembling various drones are all normal tasks.
Other non-normal tasks include repairing various war weapons, such as various special vehicles.
From the engine to the tires, there is nothing that cannot be repaired.
Not to mention that if the bucket of a demining excavator is blown to pieces, you can rub it with your own hands. Even if the main shaft of a special vehicle is broken, I dare to weld it for you.
During this period, various special alloy materials are indispensable.
If there is anything missing, you must find a solution yourself.
One is to look for second-hand substitutes, while the other is to rely on one's own efforts and make them oneself.
It’s definitely impossible to buy a new one, it’s too expensive and not profitable!
It was in that environment that Qin Jun made a lot of money as a raw material supplier.
Now that the tools in his hands are simple, he must get some simple tool steel, the simplest being high carbon steel.
With high carbon steel, let’s see if we can directly cast chisels, files and drill bits.
As long as he has these three tools, he can definitely hold a simple air gun without an air bottle in his hand!
Simple tool steel is not difficult to refine as long as you know the proportions.
Of course, the raw materials need to be of higher purity so that he can accurately control the optimal ratio of various elements.
It was definitely impossible to do it at the beginning, because the raw materials he used were incomparable to those decades later.
It's just a test now, so try to smelt the steel slag that was used up before.
These steel slags are always refined iron ore. Although there are still many impurities, it is easier than processing iron ore.
Now he can remove most of the impurities as long as he uses high temperature to melt them. As for completely removing the impurities, it is simply impossible now.
Although this is a bit wasteful, you will always get some useful materials.
After Qin Jun made all preparations, Qin Han also came over to help after dinner.
With his help pulling the bellows, the fire soon turned red.
At this time, the crucible in the furnace was also burning red and translucent, as if it was about to melt.
Of course, the crucible will not melt, but some of the steel slag inside has begun to turn red, soften, and then turn into some shiny liquid.
Among these iron juices, the easiest impurities to remove are some minerals with high melting points. At this time, just use an iron spoon to fish them out and throw them away.
It turns out that the villagers who relied on their enthusiasm to make steel did not know how to make steel at all.
Some sensible people are also very smart, but they simply know what is happening but don’t know why!
Besides, no matter how small the small blast furnace in the village is, it still has to add about ten tons of iron powder at a time.
With so much iron powder, just heating it is very troublesome. Even if there is a blower, it is of no use.
If the temperature is not reached, many times the iron powder in the small blast furnace cannot be completely melted.
Therefore, there is a large amount of so-called discarded steel slag.
But now that the Qin army uses small crucibles, the temperature can naturally be controlled.
Now as long as the ideal temperature is reached, isn't it easy for these so-called scrap steel slags to melt into molten iron?
Of course, this molten iron cannot be directly used to make steel, because what the Qin army needs is not ordinary steel.
It went very smoothly. The iron that came out of the first pot weighed four or five kilograms.
Qin Jun thought for a while and simply poured an iron pot into it to check the situation first.
After all, the iron pot mold is ready-made and he can use it directly.
If you make the mold yourself, you also need to sift the sand. After the mold making is completed, you can melt the iron, cast it, and polish it.
For some standard iron pots, old craftsmen will make several fixed molds that can be used multiple times, so that there is no need to make molds every time.
What Qin Jun is holding now is a 49-centimeter-diameter iron pot mold that is often used by villagers.
Clean the mold carefully, buckle it up, and expose the opening.
Then you can directly hold the crucible with iron tongs and pour the molten iron into the mold.
Of course, there are also many technical points here.
For example, the temperature of the molten iron, as well as the removal of impurities, and finally, try to avoid bubbles in the molten iron.
If these are not done well, the final iron pot will not be of good quality.
After the casting was completed, Qin Jun poured the last remaining special water directly into the sink next to it.
The next step is to wait. It is better to be steady when pouring a cast iron pot for the first time.
He wanted to see the situation first and then make plans.
Fortunately it was winter and the weather was very cold, so I only had to wait for more than half an hour before opening the mold.
Take apart the mold and knock it carefully. When the iron pot attached to the mold becomes loose, you can pry it off.
When he got the iron pot, although it felt a little hot, Qin Jun quickly got started.
While checking whether there are any gaps in the whole, tap it.
The sound was soft and crisp, intact, and after a careful inspection of the side, there was no trace of trachoma.
I looked carefully at one side again. The iron pot was dark overall and shone with the unique luster of metal. The most important thing was that the iron was even and without any bulges or holes.
This shows that the molten iron is melting reasonably well, there are no bubbles, and there are definitely no obvious impurities.
Without impurities, the quality of the iron pot is guaranteed.
Without bubbles, there would be no trachoma.
If it is cast well, there will be no defects, such as the two ears that are most likely to be missing.
If there is any defect, the iron pot is also a defective product.
It's fine now, it's completely normal, I just don't know how to use it.
Listening to the sound and looking at the appearance, the iron quality is relatively pure, but I don't know whether the carbon content is high or not.
And this requires checking the condition of the molten iron that was just poured into the sink.
"This...is this made...a big iron pot?"
