Chapter 293: The birth of tungsten

In the Equipment Department, Song Changping took his artillery production team to a seat.
After Song Changping became independent, Song Changping only brought the artillery production team that followed him.
Standing in front of the blackboard of the Equipment Department, Xiao Ming drew the structure diagram of the flintlock.
Whether it is a matchlock or a flintlock, the two types of firearms are muskets, and the only difference lies in the way the gunpowder is activated.
The matchlock gun is very simple, basically the same as the principle of artillery. As long as the barrel is obtained, this technique is not a problem for Song Changping.
It’s just that for Xiao Ming, it’s no longer necessary to reproduce matchlocks, and matchlocks can’t be effective against cavalry in the wild. The shot volume of two rounds in three minutes is just like the three-eyed blunderbuss of Guanning Iron Cavalry in the late Ming Dynasty. But with two bullets, the rest is hand-to-hand combat, and once the matchlock of the matchlock is extinguished, it needs to be reignited. At this time, there is no difference between the matchlock and the fire stick.
The flintlock gun avoids the situation that the matchlock is extinguished when the matchlock gun is firing, and has higher stability. This is why the flintlock gun quickly eliminated the matchlock gun.
"In general, the outer side of the flintlock gun machine is divided into four parts: the striker, the main spring, the clasp spring, and the powder pool. The striker is used to fix the flint, the main spring provides power for the striker, and the clasp spring is The iron flakes hit by the flint, the gunpowder pool is used to preload a small amount of gunpowder to ignite the gunpowder in the barrel."
"There are also triggers, movement, iron and iron springs, clasp springs, and main springs inside the gun. The trigger is used to fire, and the movement maintains and releases the power of the main spring and transmits the power to the striker. The anti-iron is when someone pulls the trigger, engages the movement, and then releases it. The buckle spring is fixedly connected to the cover of the buckle spring on the gunpowder pool, so that the flintlock can withstand wind and rain. In general, this principle is When the trigger is pulled to gather a strong force on the main spring, the stopper will engage with the movement. After the trigger is pulled, it will push the stopper forward until it can release the movement, and make the striker push the flint towards the movement. Front impact."
On the blackboard, Xiao Ming pointed to the structure of the flintlock to explain little by little, Song Changping and the craftsmen carefully remembered, and engraved all the structure of the flintlock in their minds.
At the same time, they noted the dimensions of the various structures of the flintlock on the blackboard.
In Song Changping's view, the forging of the small parts of the shot was a very troublesome thing, whether it was a striker, a spring, a movement or a trigger.
In general, the entire structure of the flintlock gun was explained. At this time, Xiao Ming said: "Now you can raise the difficulty."
"His Royal Highness, it's still the spring issue. How to make the steel elastic?" Song Changping asked the most important question.
In his opinion, if there is no way to make a spring, this flintlock will not be produced.
At this time, Xiao Ming laughed, and he said: "It was not possible, but now it is possible."
"Oh, why?" Song Changping asked strangely.
"Do you know why this king is looking for tungsten ore, but he hasn't started producing flintlocks for a long time?" Xiao Ming asked.
Song Changping shook his head.
Xiao Ming said at this time: "The barrel is only one of the problems. The barrel can be made by hand, but at that time you could only produce matchlock guns, not flintlock guns, because there was no spring steel at that time, because spring steel needed Only carbon and manganese can be produced. Even if there was a barrel at that time, it was of little use. Instead, a lot of manpower and material resources would be wasted."
After a pause, Xiao Ming said, "So now you know why this king has always been paranoid about tungsten ore, not only for the knives, but also for spring steel."
Song Changping nodded slowly. As craftsmen, they naturally know that barrels can be made by using rolled iron. However, hand-made barrels also have drawbacks, that is, barrels made by different craftsmen have errors and are very It takes time.
The structure of the flintlock was all clearly stated, and Xiao Ming asked Song Changping to assign tasks to his team.
Now that there is a lathe, the next step is to carry out assembly-line production, and the precision scales are available. Standards are established to allow craftsmen to divide the labor to manufacture different parts and finally assemble, so that the production speed of flintlocks can be increased.
After all, he couldn't compare with Western countries or even the Japanese countries with the old methods, because his fief only had 600,000 households, and all his labor came from limited slaves.
In addition to increasing the degree of mechanization, otherwise they can't compete with their enemies at all.
"His Royal Highness, I will be responsible for this spring steel." Song Changping took the initiative to provoke the most difficult part.
Xiao Ming showed a look of praise, and he said, "In that case, let's go to Zhang Liu."
Let the personnel of the Flintlock Research Team take charge of their own accessories, and Xiao Ming and Song Changping found Zhang Liu.
Nowadays, molds for boring machine tools, milling machine tools and drilling machine tools are all prepared, just waiting to extract tungsten ore.
"Prepare some charcoal, calcine the tungsten ore powder and charcoal together, and use the iron-making temperature to calcinate." In the backyard of the Equipment Department, Xiao Ming found Zhang Liu who was discussing the problem together.
After receiving Xiao Ming's order, Zhang Liu led the craftsmen to act immediately, and they could have been waiting to extract tungsten.
Based on current scientific and technological conditions, Xiao Ming can only use carbon reduction to extract tungsten. In historical data, the Spanish De Purya discovered wolframite in 1783. In the same year, he used carbon to reduce tungsten trioxide to obtain tungsten for the first time. Powder and name the element.
Therefore, it is feasible for Xiao Ming to adopt the carbon reduction method. Although the purity of tungsten extracted by this method is not high, it is more than enough in this era.
It may even make his Qingzhou lathe technology go hand in hand with the West ~EbookFREE.me~ or even surpass it.
Pour the mixture of tungsten ore powder and charcoal into a blast furnace heated by a regenerator, Zhang Liu, Xiao Ming and others waited.
After an hour, while waiting for the blast furnace to cool down, Zhang Liu took out the mixed powder through the reserved opening. At this time, some silver-white particles appeared in the black powder.
Although these particles are few, it has proved that the charcoal reduction method successfully extracted tungsten.
"His Royal Highness, are these silver-white particles tungsten?" Zhang Liu asked. When mixing materials, he had never seen such silver-white particles. The only answer was that this kind of thing was tungsten.
Xiao Ming nodded, with joy in his eyes. This is another technological breakthrough in Qingzhou. He said, "Yes, this is tungsten. Now we can produce tungsten steel."
With a thick smile on the faces of the craftsmen Zhang Liu and others, he immediately said: "Go and take a sieve to sift out the tungsten, then take some charcoal and continue to extract the tungsten.
