Although Shi Xiong doesn't know much about the heat treatment process of steel, he has heard about the "four fires" of the heat treatment process of steel.
Annealing, normalizing, quenching and tempering are four kinds of fire in steel heat treatment process.
Just like when the barrel was made yesterday, when the molten steel was poured into the mold, it was naturally cooled. That is normalizing, which is similar to the effect of annealing. Anyway, it is a way of natural cooling.
And quenching, is in the high temperature state of the workpiece immersed in cold water or cold oil for rapid cooling. Quenching will make the steel used to make the workpiece hard and brittle, which is much harder than the steel under natural cooling.
Of course, because quenching will make the steel brittle, it is better to have a tempering treatment. That is to heat up the quenched workpiece to about 700 ℃ again for a long time, and then cool it naturally. In this way, the hardness of the workpiece is improved, but the toughness is also increased.
Shi Xiong knows a little about the general theory of heat treatment just now, but he really doesn't know how to carry out heat treatment. Even the most common quenching process, he has seen it in movies or TV. He has never operated it himself.
As for the hardness of the tools made by Lieutenant Ferguson, stone bear is not worried. Because the hardness of the hardened workpiece is much higher than that of the original steel. If this tool is too brittle, give him a look at how tempering works, and then let this guy figure it out for himself.
However, looking at the look of lieutenant Ferguson, he obviously knows what quenching is all about.
Of course, it's not enough to know what the quenching process is, especially the barrel just made yesterday. I'm afraid it's not enough for Lieutenant Ferguson to do experiments.
So, as long as this guy is interested in the new gun, he will certainly learn more knowledge to serve his new gun. For example, how to make steel, how to make mold, how to make barrel
All these things complement each other. If there is less than one, new guns will not be produced.
It's only by getting Lieutenant Ferguson interested in more and more things that he'll be able to stay in the high tree tribe for a while longer.
Stone bear has never thought of keeping Lieutenant Ferguson around forever, and stone bear can't do it. Patrick Ferguson is a very loyal soldier to the British Empire. If the British Empire is OK, Lieutenant Ferguson may stay in the gaoshu tribe for a longer time. Even before the start of the independent war, the stone bear is confident of this.
But once the war of independence started, as a loyal British officer, no matter how good the terms offered by stone bear were, I'm afraid it would be impossible to retain Lieutenant Ferguson. He will not hesitate to leave everything here, carrying a gun to the battlefield, even if he is facing death, he will not stop.
In this regard, stone bear had thought of this when he left Lieutenant Ferguson at the beginning.
However, there are still 11 years left between now and the outbreak of the war of independence, and there are no major events in Britain during this period. Therefore, if Lieutenant Ferguson can be left here to develop new weapons for himself, it will surely make a qualitative leap in the weapon system of gaoshu tribe.
Even if Lieutenant Ferguson eventually returns to the British army and brings these new technologies to the UK, the gaoshu tribe will still take the lead.
In addition, stone bear didn't intend to let Lieutenant Ferguson work alone. Both rabbit mouth and hard bone showed strong interest in guns. At that time, he arranged these two little guys next to lieutenant Ferguson. While he was working as an assistant, he learned about the weapons that lieutenant Ferguson held.
Stone bears don't believe that they can't empty Lieutenant Ferguson in ten years' time with rabbit's mouth and hard wit!
So from that day on, the rabbit's mouth and hard bone became the two tails of lieutenant Ferguson's side. For these two little guys, Lieutenant Ferguson also likes them. After all, the Indian's unique simplicity is enough to make Lieutenant Ferguson feel different care.
Even Ferguson often teaches rabbit mouth and hard bone to speak English, and the talent of these two guys in language is a bit surprising to stone bear.
Ferguson had to build a barrel to test different guns, so he needed a lot of steel.
For this reason, the stone bear even did not hesitate to launch the whole clan once again to excavate iron ore, limestone and coal. This excavation benefited from the large-scale use of iron and the use of four wheeled carriages, so in a few days, more than 200 people dug up a large amount of iron ore, limestone and coal.
Stone bear is ready to start coking alone.
Last time, because we had to take care of firing refractory bricks, Shi Xiong used the simplest way to make coke. As a result, the coking effect was not ideal.
In order to improve the success rate of coking as much as possible, Shi Xiong decided to adopt the earth kiln coking method.
This kind of earth kiln coking is the coking method that Shi Xiong wanted to use but didn't use last time. The yield of earth kiln coking is much higher than that of the big pit coking method that Shi Xiong used last time. Therefore, Shi Xiong plans to produce more coke at one time.
As a rule, the whole clan is mobilized. Under the current situation, Shi Xiong doesn't even need Li Lei to speak. As long as he says "I'm going to turn on the furnace again for steelmaking", almost all the clansmen who can bomb will come to help.
Although the quality of steel produced in the last steelmaking was not up to standard, 90% of the steel was tempered into pig iron, and the quantity was only about three tons, it still made the whole family happy for a long time.
In the past, people in the clan wanted to use the precious fur to exchange with vasichu's trading team. But now, under the command of the guardian, they can make steel. Who doesn't want the guardian to turn on the furnace several times and make more steel?
In any case, iron ore, limestone and coal are free of charge. They only need to spend some energy to make steel from these things. Who is not willing to do it?
All the people in the tribe are not fools. After refining steel, making salt and using new farm tools, they have fully understood the care of the guardian. He is sincere for the good of the tribe!
So, it's no exaggeration to say that even if Li Lei comes forward and orders the people not to obey Shi Xiong's orders, it is estimated that at least nine of the ten people will not obey Li Lei's orders, and the rest is because they are little baby and can't understand Li Lei's orders.
If it wasn't for the fact that Hongyun, the kabulu sacrifice, had never spoken, the people of the clan would have wanted the stone bear to replace Lilei as the new clan leader!
Don't doubt it. Most of the people now think so.
In this case, whether ancient or modern people, whether Chinese or Westerners, are the same.
Who can make our life better, we follow who, we support who!
