Although the tonnage of copper crucible is low, at least it will not destroy the material, which is fundamental, and it is still necessary to refine a furnace and destroy a furnace. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

But with Chu Hao's current identity, speaking will definitely not be untargeted, if Chu Hao can really solve the shortcomings of graphite, then I am afraid that the entire scientific research field of titanium alloy metallurgical equipment, and even rare metal metallurgical equipment, will be turned upside down!

"Yes. Chu Hao nodded.

In an instant, everyone's expressions froze, their eyes widened, and they looked at Chu Hao in disbelief, but their hearts were already overturned, and the waves were turbulent.

It's really amazing, Chu Hao actually admitted that he can solve the shortcomings of graphite materials as a crucible, if what Chu Hao said is true, this matter is probably the most shocking thing heard from the workers who developed smelting equipment in recent years.

"Do you really have a solution?" Director Zhu stumbled.

The title of Chu Hao has directly evolved to your level.

No way, if Chu Hao can really solve it, Chu Hao may immediately become the number one leader in the field of smelting equipment, there are many things he needs to learn, say you, don't lose.

"There really is, but Director Zhu doesn't have to be so polite, you don't even need to call Mr. Chu, you just call me Xiao Chu. ”

"You are too polite, if you can solve it, you have made an indelible contribution to the smelting equipment and even the metallurgical field, and your name will be engraved on the bronze pillar of history. ”

After speaking, Director Zhu looked at Chu Hao with blank eyes, he was already scratching his heart with a hundred claws at the moment, and he couldn't wait to pry Chu Hao's brain open immediately to see what the solution was.

Chu Hao smiled slightly, and he didn't plan to sell it, and said directly: "I'm going to apply one layer, or several layers of enamel layers, to the graphite crucible to solve this problem." ”

As soon as these words came out, everyone's eyes lit up, the enamel layer, the most common is on ceramics, is a kind of colorless or colored vitreous thin layer made of various mineral raw materials according to different formulas covering the surface of ceramic products.

The enamel layer has the ability to densify the porcelain, soft luster, and impermeable to water and gas, giving people a bright and mirror-like feeling. At the same time, it can improve the use strength and chemical stability, prevent pollution, facilitate cleaning, and reduce corrosion.

The enamel layer itself is an incomparably inert existence, and if it is applied to the graphite crucible, it can indeed change the problem that graphite is easy to carburize.

But the problem is that the melting point of the enamel layer is 1380 °C, while the melting point of pure titanium is 1678 °C.

In this way, the temperature has not yet reached the melting point of the titanium alloy through electrode heating, and the enamel layer on the graphite crucible is melted, so it is impossible to provide protection for the titanium alloy and isolate the role of the graphite crucible.

Chu Hao naturally saw the question in everyone's eyes, "The enamel layer on ceramics is made of feldspar, quartz, talc, kaolin, etc., but the enamel layer I said is made of other materials, and its melting point can be as high as 1800 °C." ”

Director Zhu, as well as the others present, even Xiao Liu, who had provoked Chu Hao just now, all felt inexplicably excited at this time, as if they were witnessing history.

Although no one knows what Chu Hao's enamel layer is, at least judging from what Chu Hao said before, what he said is targeted.

"In the institute, are there any kinds of metal material powders, to be finer, at least 500 mesh, I want to do an experiment. Chu Hao asked.

The physical definition of mesh is the particle size or coarseness of the material, and the general definition refers to the number of holes in the screen within 1 inch. The more meshes, the finer they are, 500 mesh, which is basically equivalent to the particle size of powder at about 0.028 mm.

"If we talk about all kinds of metal material powders, we have them here, but if they are as fine as 500 meshes, then we can only borrow them from the titanium alloy laboratory. Director Zhu thought for a moment and said.

"That's troublesome Director Zhu. ”

Saying that, Chu Hao followed Director Zhu to the titanium alloy laboratory, the equipment here is basically the same as the material laboratory of Shangda, but the equipment is obviously much better, some of them should be made by Director Zhu himself, and the use effect should be much better than normal experimental instruments.

This kind of first-served treatment is also available in a large-scale research institute like Panxi Vanadium Titanium Steel Research Institute, which integrates gold research and development and equipment research and development.

Chu Hao arrived at the titanium alloy laboratory, and without waiting for Director Zhu's introduction, the people in the titanium alloy laboratory recognized Chu Hao, and instantly surrounded him, very enthusiastic, all kinds of problems were thrown over like rotten eggs, this is also a group of scientific researchers with master's and doctoral education, it is simply a group of fifteen or sixteen-year-old fans who see the feeling of idols, this is completely different from Chu Hao's treatment of being coldly watched, nitpicking, and picking his nose and eyes at Director Zhu.

But this is also normal, speaking of which, the people in the titanium alloy laboratory are Chu Hao's peers, the descendants of the Eight Classics, I don't know how many times I have read the report about Chu Hao, I don't know how many times the experiment on Chu Hao's paper has been repeated, it is possible that Chu Hao is being dreaming about it.

Besides, they are not stupid, no one knows that Chu Hao's future is limitless, almost eighty percent of them are the top masters in the field of titanium alloys, what are you waiting for if you don't take advantage of the familiarity now.

Chu Hao accompanied them for a conversation, and then was pushed into the laboratory by Director Zhu's subordinates, a group of impatient researchers.

Their voices were about to smoke, and if they didn't push Chu Hao into the experiment, they wouldn't have to see the enamel layer of this graphite crucible today.

At this time, no one was prejudiced against Chu Hao anymore, but had a sense of pride in witnessing history.

After entering the laboratory, according to Chu Hao's instructions, the metal material powder was moved, and everyone left the laboratory with interest.

This is not a normal experimental process, they will take a look at it, according to Chu Hao's posture, it is clear that the finished product is going to be directly produced, how can they be embarrassed to look at it again.

Chu Hao picked up bags of metal material powder on the ground, weighed them on the balance according to the recipe, and threw them directly into the mixer, then added a certain amount of water, and stirred them directly.

Metallic coatings are actually a very interesting thing, which can appear in almost any place, even on people's faces, such as the titanium dioxide mentioned earlier, or the lead in cosmetics before, and it can even be said that these cosmetics are a combination of metal elements.
