"Tungsten ore has fallen?"

Joy instantly enveloped Xiao Ming, this tungsten ore has been found for almost a year now, and now it is finally settled. Pen, fun, pavilion www. biquge。 info

"Your Highness, the old slave's prospecting has indeed found tungsten ore, this New Year has this good omen, look at His Highness's fortune this year will be very prosperous." Qian Dafu grinned.

During this trip to Dengzhou, Xiao Ming's mood was originally a little resentful, but now this good news immediately made him energetic, and he said: "When you go to the main hall, you come 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?" ”

"Your 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, only 200 miles apart, and in the plan of the Wa State, three years later, the plan of the Wa State is to land in Dengzhou, and then invade Laizhou, and then occupy the Shandong Peninsula.

In Xiao Ming's science and technology library map, it seems that only Laizhou in Shandong has tungsten ore, so it can be said that this tungsten ore is very important to him, and once lost, it will seriously affect the development of science and technology in the next step.

Therefore, tungsten ore was found in Laizhou, and he could not lose the cave Dengzhou, Laizhou line, not to mention that these two coastal states are important outlets to the sea.

"Immediately organize slaves to go to tungsten mining, if there are not enough manpower, mobilize manpower from other mines, this matter cannot be delayed, you go immediately!"

Xiao Ming said solemnly.

Now that tungsten ore has been found and cobalt has been found, he can use these two materials to 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 now.

Xiao Ming's tone was as urgent as expected, Qian Dafu realized the importance of this issue, and he nodded, "Your Highness, the old slave will go and mobilize people now." ”

Qian Dafu hurriedly prepared for the mining of tungsten ore.

Xiao Ming is not idle, now that the tungsten ore has been found, the sintering of tungsten steel knives will be carried out next, and this is an equally difficult technology.

Different from steelmaking, the production of tungsten carbide knives needs to go through milling, wet grinding, mixing, crushing, drying, sifting, adding cobalt, then drying, sieving to prepare the mixture, granulation, pressing, forming, low-pressure sintering, forming (blank), cylindrical grinding and other procedures.

First of all, the purification of tungsten is a big problem, because although Laizhou has found tungsten ore, but this tungsten ore is a poor ore, which must be enriched and screened into concentrate in order to be effectively refined, otherwise a lot of energy can not be purified to a sufficient amount of tungsten powder.

Secondly, another problem in this process is the pressing molding, because of the characteristics of tungsten ore, if you want to produce a tool, you must press the tungsten ore powder into the shape of the knife and then sinter.

Before that, tungsten steel dies had to be forged.

The chair in the main hall was not yet hot, and Xiao Ming got up and went to the instrument department at this time.

"Chen Wenlong, call Zhang Liu."

As soon as he arrived at the Equipment Division, Xiao Ming said directly to Chen Wenlong.

Now Chen Qi is in charge of the production of the military workshop, and now the leader of the craftsmen of this equipment department has become Zhang Liu.

This Zhang Liuke is the most skilled craftsman outside of Chen Qi, and it is for this reason that he was so nervous last time, after all, this Zhang Liuke is one of the pillars of the Instrument Division.

Zhang Liu, who smelled of steel, came soon, he was repairing the water conservancy forging hammer with the craftsmen just now, during this time, the steel workshop has been producing parts for pulley crossbows, and the workload is large, and the water conservancy forging hammer often has problems.

And the craftsmen who can repair the hydraulic forging hammer are only a few craftsmen who have participated in the manufacture of the equipment department.

"Your Highness." Zhang Liu wiped the sweat from his forehead and bowed down and said.

Seeing that Zhang had arrived, Xiao Ming said: "You immediately call a few more excellent craftsmen from the Equipment Division to come over, and now you are going to produce tools for lathes." ”

"Knives! Has tungsten ore been found? Hearing this, Zhang Liu suddenly said excitedly.

Xiao Ming nodded and said to him: "That's right, Qian Dafu just told this king that this tungsten ore was discovered in Laizhou, and now you have to start preparing the mold in advance." ”

"Great." Zhang Liu's face was full of excitement.

A year ago, all kinds of lathes were placed in the water conservancy lathe workshop in Qingzhou, but because of the unqualified tools, these lathes were basically used to process wooden accessories, but they were rarely used to produce steel accessories, because a tool was often scrapped because of cutting a steel, so come and go, the lathe workshop could not make any decent tools.

Later, due to the need to build Galen ships, this lathe workshop was completely reduced to a carpentry factory.

But they had been looking forward to the day when they would be able to use these lathes, and if they could work steel as well as wooden fittings, they believed they would be able to make something even greater than the Galen ship.

"Don't be happy first, this king will tell you about the production process of this tungsten steel cutter."

The twelve craftsmen involved 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 the picture of tungsten steel production suddenly appeared in the minds of Zhang Liu's people, as if he was in the scene.

This feeling did not appear once or twice, now they are used to it, in their opinion, this is Xiao Ming's very vivid and vivid talk, and they would never have thought that these paintings are full of scientific and technological crystals.

"Your Highness, this time it's just a tool for the production of milling machines, boring machines, and drilling machines?"

"Yes, because these three kinds of lathes can basically produce our spare parts, you can't chew more, you still have to find out how these three kinds of lathes process steel." Xiao Ming said.

Zhang Liu and others nodded, the tools of these three kinds of lathes are different, the drilling machine tool is good to say, it is just a cylindrical drill bit, and the tools of the milling machine and boring machine are very complex, whether it can accurately forge such a mold is still a problem.

After teaching the three of them this time, Xiao Ming did not leave, and picked up the pen in the instrument department to draw the knife graphics, and also marked the size on the knife.

Since the announcement of the Unified Weights and Measures at the conference, the Apparatus Division and the Military Workshop have first used scientific measurement methods.

Millimeters, centimeters, meters these dimensions have replaced the previous centimeters and inches, thus making the production more refined.

Now that the production of knives is about to be made, the production of Qingzhou must enter the fine production, and the condition of the fine production is the precise size.

So before Zhang Liu could make the mold, he had to come out with a precise measuring tool.

Thinking of this, Xiao Ming asked Chen Wenlong to make a compass for him.
