Chapter 229 High Purity Single Crystal Alloy Smelting

The audience in the live broadcast room watched as Han Won sorted all the metals and crushed them into flakes, and then put them into a metal shredder to crush them.

Then collect it and put it into a powder grinder to slowly grind it into metal powder, which is a bit curious.

[What is this for? 】

【Why do you want to break a good metal?Refurbish it? 】

[Powder metallurgy? 】

[I don’t think so, the fineness of the alloy powder required by powder metallurgy is very high, and this grinding method will definitely not be able to achieve it. 】

[Isn't it manufacturing aircraft? 】

Even experts and scientists from various countries squatting in the live broadcast room are a little curious.

The fineness of these metals can be seen from the live broadcast, and they all belong to high-quality metal ingots, the kind with high purity.

Why crush and grind into powder?
If it is powder metallurgy, as some knowledgeable viewers in the live broadcast room said, this grinding method certainly cannot meet the requirements of powder metallurgy.

But this anchor will never do meaningless things, so this step must be very important.

Since the other party didn't explain it, just deal with it first.

One step late, one step late, one step early, one step early.

At the stage of being able to imitate and reproduce, no country wants to lag behind.

What if the finished product of electric propulsion is really awesome?

Wearing a mask and plastic gloves, Han Yuan looked at the barrage from time to time while handling metal.

This step is still very easy. You only need to put various metal ingots into the industrial equipment, and the finished product will come out naturally, without any effort on his part.

Seeing the barrage on the virtual screen, Han Yuan explained:

"The reason why these metals are crushed and ground into powder is to facilitate subsequent operations."

"These metal ingots are provided by the team behind me. Although the purity is relatively high, they still cannot meet the requirements for manufacturing 'electric propulsion-free engine' accessories."

"So in the first step, I need to further purify it before I can use it."

"As for the method, the method of purifying each metal is different."

"For example, titanium, the method of decomposing ilmenite with sulfuric acid is commonly used in industry to produce titanium dioxide, and then produce metal titanium from titanium dioxide."

"As for the detailed steps, I won't go into details."

"The ultimate goal is to smelt single crystal alloy materials after obtaining high-purity metals."

"Compared with normal alloy materials, single crystal alloy materials have excellent high temperature creep resistance, thermomechanical fatigue resistance, oxidation corrosion resistance and high temperature bearing capacity."

"The most important thing is that the titanium-rhenium-aluminum single crystal alloy material has a certain high-temperature diamagnetism, and can maintain a good magnetic crystal at a temperature of [-] degrees."

"Smelting single-crystal alloy materials with high-temperature diamagnetic properties is my ultimate goal."

"Without this single-crystal alloy material, the electrothermionic propulsion system of 'electric propulsion-free engine' cannot be fabricated at all."

Hearing this, the audience in the live broadcast room suddenly understood.

After a busy morning, Han Yuan finally smashed all the metal materials he brought.

These ground gray metal powders are packed in glass bottles of various sizes, and the jars are brought to the chemical laboratory for the next step: "purification".

These products produced by physical grinding production methods are compared with those produced by chemical methods.

Both quality and productivity are greatly lacking.

And when grinding, it is easy to mix impurities.

Therefore, in modern industrial production, unless in special circumstances, almost no physical grinding method is used to produce metal powder.

But there is no way for the Korean won.

Really high-purity powder metallurgy is either smelted by ionizing the metal and spraying it.

Either the plasma is used to melt at least a part of the metal raw materials in the reaction vessel to form molten metal, and then the molten metal is evaporated at ultra-high temperature to generate metal vapor.

The formed metal vapor is then conveyed to cooling tubes where the metal vapor is cooled and condensed to produce metal powder.

These two types of ultra-difficult powder metallurgy require high-tech equipment. Although he upgraded the industrial equipment once, it still cannot reach this level.

For him, the only way to smelt pure titanium with a purity of 90.00% or more is electrolysis.

Although the cost is high, and the waste electrolyte will cause environmental pollution, but fortunately, the amount is small.

He only needs to smelt the single crystal alloy material, and then exchange it through the system mall.

There's no way around that. This broken system provides various metal ingots, even if they are of the same kind, they are still categorized.

For example, if a piece of iron is smelted, it will be of the same purity as it was smelted.

If he wanted to obtain pure metal with a purity of more than 99.999%, he had to smelt it himself before he could exchange it.

In the design drawing, the number of various alloys required is not a small number.

In particular, single crystal alloy materials for the manufacture of electric propulsion engines require high purity metal materials, and the amount is not small.

After all, he himself is going to go to the sky with the aircraft.

In this way, the overall size of the aircraft must not be too small.

In the design drawings, the diameter of the entire aircraft is [-] meters, and the maximum height is [-] meters.

For an aircraft of this size, even though the alloy used by Korean Won is very light titanium-aluminum alloy, the weight of the entire aircraft still exceeds [-] tons.

After all, no matter how to reduce the design, the necessary equipment and equipment to ensure your own safety are essential.

Among them, only high-energy storage lithium batteries accounted for [-] tons.

What is left is the metal shell of the aircraft, the electric propulsion engine, gallium arsenide silicon thin-film solar thin-film power generation panels, computer control systems and other things.

But compared to the huge thrust that the electric propulsion engine can provide, this weight is nothing.

Moreover, the designed aircraft does not rely entirely on engines to increase thrust.

Just like airplanes and fighter jets, the long and narrow wings can provide most of the power for the plane to rise, and the thrust provided by the engine is only a small part of the lift.

Although the aircraft designed by Korean Won is triangular, the corners and the whole will also provide a lot of lift.

Although it is not as exaggerated as that provided by ordinary wings, the overall lift is not small, and it can save a lot of energy.

This part is naturally something that every designer will consider.

When he came to the chemical laboratory, Han Yuan first took out the electrolytic container prepared in advance, then prepared the electrolyte, and blended the brought metal powder into the electrolyte according to the corresponding classification.

Different metals use different electrolytes. Although sulfuric acid is widely used, it is not suitable for all metals.

Sulfuric acid can be used for electrolytic purification of titanium, but hydrochloric acid is used for electrolytic purification of magnesium. The chemical electrolytic smelting methods and electrolytes of various metals are different.

　Adjusted and optimized the thrust of the electric propulsion engine, and changed the hundred N level to KN level, because the original aircraft weight design seems to be a bit inconsistent, sorry, it affects the reading experience.
