Chapter 287: Tungsten

"Has the tungsten ore gone?"
Joy enveloped Xiao Ming in an instant. It has been almost a year since the tungsten mine was found, and now it has finally settled.
"His Royal Highness, the old slave's mine search did find a tungsten mine. There is a good omen in this Chinese New Year. It seems that your fortune this year will be very prosperous." Qian Dafu grinned.
On this trip to Dengzhou, Xiao Ming was initially a little bit angry. Now the good news immediately made him refreshed. He said, "When you get to the main hall, you will talk to me slowly."
Qian Dafu smiled, and followed Xiao Ming to the main hall.
The two sat down and Xiao Ming asked eagerly, "Where is the specific location of this tungsten mine?"
"His Royal Highness, it's fifty miles outside Laizhou City." Qian Dafu said.
Laizhou and Dengzhou are adjacent to each other, and they are also two states on the peninsula. They are only two hundred miles apart. In the plan of the Japanese nation, three years later, the plan of the Japanese nation is to land in Dengzhou, then occupy Laizhou, and then occupy the Shandong Peninsula.
In Xiao Ming's science and technology library map, it seems that only Laizhou has tungsten ore in Shandong. Therefore, it can be said that this tungsten ore is very important to him. Once lost, it will seriously affect the development of the next step of science and technology.
Therefore, when tungsten ore was discovered in Laizhou, he couldn't lose the cave Dengzhou, Laizhou first line, not to mention these two coastal states are important outlets to the sea.
"Immediately organize the slaves to go to the tungsten mine to mine. If the manpower is not enough, mobilize manpower from other mines. This matter cannot be delayed. You should do it immediately!"
Xiao Ming said solemnly.
Now the tungsten ore has been found, and the cobalt has also been found. Using these two materials, he can produce tungsten steel and high-speed steel, which are the best tools for lathes.
Although there is no way to sinter tungsten steel as hard as modern tungsten steel at the current level of Qingzhou, it is at least enough to surpass the steel produced in Qingzhou.
Xiao Ming's tone was urgent as expected. Qian Dafu realized the importance of this issue. He nodded, "His Royal Highness, the old slave is going to mobilize manpower now."
Qian Dafu hurriedly prepared tungsten mining.
Xiao Ming was not idle either. Now that the tungsten ore has been found, the next step is to sinter the tungsten steel tools, which is an equally difficult technique.
Different from refining steel, the production of tungsten steel tools requires powder milling, wet milling, mixing, pulverization, drying, sieving, adding cobalt, then drying, sieving to make a mixture, granulating, pressing, and forming. Low-pressure sintering, forming (blank), cylindrical grinding and fine grinding procedures.
First of all, this purification of tungsten is a big problem, because although Laizhou has found tungsten ore, this tungsten ore is a poor ore. It must be enriched and screened into a concentrate to be effectively refined, otherwise a lot of energy is wasted but sufficient quantity cannot be purified. Tungsten powder.
Secondly, another problem in this process is press molding. Because of the characteristics of tungsten ore, it is necessary to press tungsten ore powder into the shape of the tool and then sinter it in order to produce tools.
Before that, tungsten steel molds must be forged.
Before the chairs in the main hall were warm, Xiao Ming got up and went to the equipment department.
"Chen Wenlong, call Zhang Liu."
Upon arriving at the Department of Equipment, Xiao Ming said directly to Chen Wenlong.
Chen Qi is now in charge of the production of the military workshop, and now the head of the craftsman of this equipment department has become Zhang Liu.
This Zhang Liu is the most skilled craftsman outside of Chen Qi. It is for this reason that he was so nervous last time. After all, this Liu is one of the pillars of the Equipment Department.
Zhang Liu, who smells like steel, came quickly. He was repairing the hydraulic forging hammer with the craftsmen just now. During this time, the steel workshop had been producing parts for the pulley crossbow, and the workload was heavy. This hydraulic forging hammer often had problems.
The craftsmen who can repair the water conservancy hammer are also a few craftsmen who have participated in the manufacture of the equipment department.
"His Royal Highness." Zhang Liu wiped the sweat from his forehead and bowed.
Seeing Zhang Liu arrived, Xiao Ming said: "You immediately call in a few more excellent craftsmen from the Equipment Department. Now you are going to produce tools for lathes."
"Knife! Did you find the tungsten mine?" Zhang Liu said excitedly after hearing this.
Xiao Ming nodded and said to him: "Yes, Qian Dafu just told the king that this tungsten mine was discovered in Laizhou, and now you should start preparing molds in advance."
"Great." Zhang Liu's face was full of excitement.
A year ago, various types of lathes were placed in the water conservancy lathe workshop in Qingzhou. However, because of the unqualified tools, these lathes were basically used to process wooden parts, but they were rarely used to produce steel parts. Because cutting a piece of steel will be scrapped, it comes and goes, the lathe workshop simply can not produce any decent tools.
Later, because of the need to build Galen ships, this lathe workshop was completely reduced to a woodworking factory.
But they have been looking forward to the day when these lathes can be used. If steel can be processed like wooden parts, they believe that they will be able to make something even greater than Galen.
"Don't be happy, I will tell you about the production process of this tungsten steel tool."
The twelve craftsmen who participated in the production of tungsten steel were all in place, and Xiao Ming immediately began to teach them production techniques.
Xiao Ming drew and wrote on the blackboard, and Zhang Liu's people suddenly appeared in the mind of tungsten steel production, as if they were on the scene.
This feeling didn't appear once or twice. Now they are used to it. In their opinion, this is what Xiao Ming said is very vivid and lifelike. They would never think that these paintings are full of technology spar.
"His Royal Highness, this time just produce cutters for milling machines, boring machines, and drilling machines?"
"Yes, because these three types of lathes are basically able to produce our spare parts, so you can't chew too much, so you should first understand how these three types of lathes process steel." Xiao Ming said ~EbookFREE.me~ Zhang Liu and others nodded. The tools of these three types of lathes are different. Fortunately, the drilling tools are just a cylindrical drill, and the tools of milling and boring machines are very complicated. Can such a mold be accurately forged? Questions.
After teaching the three of them this time, Xiao Ming did not leave, and he picked up a pen in the Department of Equipment and drew the tool graphics, and at the same time marked the size of the tool.
Since the announcement of the unification of weights and measures at the meeting, the Equipment Department and the Military Workshop have first used scientific measurement methods.
The dimensions of millimeters, centimeters, and meters have replaced the previous points and inches, making production more refined.
Now that we are about to produce tools, Qingzhou's production must enter refined production, and the condition of refined production is precise dimensions.
Therefore, before Zhang Liu made the mold, he had to take out accurate measuring tools.
Thinking of this, Xiao Ming asked Chen Wenlong to make a compass for him.
