Chapter 288

"Is tungsten mine available?"

Joy immediately enveloped Xiao Ming. It took almost a year to find the tungsten mine, and now it's finally settled.

"Your Highness, I did find tungsten ore in my search. This new year's festival has a good omen. You can see that your Highness's fortune will be very prosperous this year." Qian Dafu grinned.

Xiao Ming's mood was a little resentful during his trip to the state. Now the good news immediately made him energetic. He said, "come to the main hall, please talk to me slowly."

With a smile on his face, Qian Dafu followed Xiao Ming to the main hall.

As they sat down, Xiao Ming asked eagerly, "where is the specific location of the tungsten mine?"

"Your Highness, it's fifty miles outside Laizhou City." Qian Dafu said.

Laizhou and Dengzhou are adjacent to each other. They are also two states on the peninsula, with a distance of less than 200 Li. In the Japanese plan, three years later, the Japanese plan was to land in Dengzhou, occupy Laizhou and then occupy Shandong Peninsula.

In Xiao Ming's map of science and Technology Library, it seems that only Laizhou in Shandong has tungsten mines. Therefore, it can be said that this tungsten mine is very important to him. Once it is lost, it will seriously affect the next step of scientific and technological development.

Therefore, if the tungsten mine is found in Laizhou, he can't lose his cave and go to Laizhou. Besides, these two coastal states are important sea ports.

"Immediately organize the slaves to go to the tungsten mine for mining. If there are not enough people, you can mobilize people from other mines. This matter can't be delayed. You should do it immediately!"

Xiao Ming said seriously.

Now tungsten has been found, and cobalt has been found. Using these two materials, he can produce tungsten steel and high speed steel, which are the best cutting 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. Qian Dafu realized the importance of this problem. He nodded, "Your Highness, I'm going to mobilize people now."

Qian Dafu was in a hurry to prepare for the tungsten mining.

Xiao Ming is not idle. Now that the tungsten ore has been found, the next step is to sinter tungsten steel cutting tools, which is also a very difficult technology.

Different from steel refining, the production of tungsten steel tools needs to go through the following procedures: pulverizing, wet grinding, mixing, crushing, drying, sieving, then adding cobalt, drying, sieving, then making mixture, granulating, pressing, forming, low-pressure sintering, forming (blank), cylindrical grinding and fine grinding.

First of all, the purification of tungsten is a big problem, because although Laizhou has found a tungsten mine, the tungsten mine is a lean one. It must be enriched and screened into a concentrate in order to be effectively refined, otherwise a lot of energy will be wasted but enough tungsten powder will not be purified.

Secondly, another problem in this process is pressing. Because of the characteristics of tungsten ore, if you want to produce cutting tools, you must press tungsten ore powder into the shape of cutting tools for sintering.

Before that, tungsten steel mould must be forged.

Before the chair in the main hall was hot, Xiao Ming got up and went to the equipment department.

"Chen Wenlong, call Zhang Liu."

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

Now Chen Qi is specially responsible for the production of the military workshop. Now the head of the craftsman of the equipment department has become Zhang Liu.

Zhang Liu is the most skillful craftsman besides Chen Qi. It is for this reason that he was so nervous last time. After all, Zhang Liu is one of the pillars of the equipment department.

Zhang Liu, who is full of the smell of steel, is coming soon. Just now, he is working with the craftsmen to repair the water hammer. During this period, the steel workshop has been producing the parts of the pulley crossbow. With a heavy workload, the water hammer often has problems.

And the craftsmen who can maintain the water hammer are just a few craftsmen who once participated in the manufacture of the equipment department.

"Your Highness." Zhang Liu wiped the sweat on his forehead and said with a bow.

Seeing that Zhang had arrived, Xiao Ming said, "you immediately summon some excellent craftsmen from the equipment department. Now you are going to produce lathe cutters."

"Knife! Have you found the tungsten mine? " Hearing this, Zhang Liu said excitedly.

Xiao Ming nodded and said to him, "that's right. Qian Dafu just told me that the tungsten mine was found in Laizhou. Now you should start to prepare the mold in advance."

"Great." Zhang left his face full of excitement.

A year ago, there were all kinds of lathes in the water conservancy lathe workshop in Qingzhou. However, because of the unqualified cutting tools, these lathes are basically used to process wood parts, but they are rarely used to produce steel parts, because a cutting tool is often scrapped because of cutting a steel. In this way, the lathe workshop can not produce any decent cutting tools.

Later, because of the need of building Galen ship, the lathe workshop was completely reduced to a woodworking factory.

But they have been looking forward to the day when they can use these lathes. If they can process steel like wooden parts, they believe that they can make something even greater than the Galen.

"Don't be happy. Let's talk about the production process of tungsten steel cutting tools."All the 12 craftsmen who participated in tungsten steel production were in place, and Xiao Ming immediately began to teach them production technology.

Xiao Ming was drawing on the blackboard, and Zhang Liu's mind suddenly appeared the picture of tungsten steel production, as if he was personally on the scene.

This feeling doesn't appear twice at a time. Now they are used to it. In their opinion, it's what Xiao Ming said. It's very vivid and lifelike. They would never think that these paintings are full of crystal stones from science and technology.

"Your Highness, this time it's just for milling machines, boring machines and drilling machines?"

"Yes, because these three kinds of lathes can basically produce our spare parts. You can't chew too much. You'd better find out how these three kinds of lathes process steel first." Xiao Ming said.

Zhang Liu and others nodded. The tools of these three lathes are different. It's a good thing to say that the drilling tool is just a drill bit similar to a cylinder, while the tools of milling and boring machines are very complex. It's still a question whether such a mold can be forged accurately.

After three professors finished teaching this time, Xiao Ming didn't leave, and he picked up a pen in the equipment department to draw the cutter figure, and at the same time marked the size on the cutter.

Since the announcement of unified weights and measures at the meeting, the equipment department and the military workshop first used scientific measurement methods.

Millimeter, centimeter, meter these dimensions replace the previous minute, inch, so that the production is more refined.

Now we are going to produce cutting tools. The production of Qingzhou must go into fine production, and the condition of fine production is accurate size.

So 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.
