Product Description

 

Specifications for Graphite Silicon Carbide Crucible For Aluminum Melting :

1.Long working lifetime: its working lifetime is increased 3-5 times over normal clay-crucible due to the compact body formed under high pressure.

2.High thermal conductivity: high-density body and low apparent porosity greatly improve its heat conductivity.

3.New-style materials: new heat conduction material ensures faster heat conductivity and pollution-free product, reduces adherent slag.

4.Resistance to corrosion:better anti-corrosion than normal clay-crucible.

5.Resistance to oxidation: advanced process dramatically improves its oxidation resistance, which ensures persistent heat conductivity and long working lifetime.

6.High-strength: high-density body and logical structure make the product better compression property.

7.Eco-friendly: energy-efficient and pollution-free, not only ensure metal product purity, but also ensure sustainable development on environment.

8.Multi-function: Can be used in induction graphite crucible furnace

Physicochemical Properties of graphite crucible:

 

The crucible is an utensil or melting tank vessels that is made of refractory material (such as clay, graphite, quartz or difficult molten metal iron, etc.).

Graphite crucible, with is special advantages and Plasticity, is widely used in the smelting area, e.g. gold smelting, silver smelting, aluminum smelting, cooper smelting, etc.

Q:How to calculate the loss of aluminum slag melting?
50-70% or so, the yield is ok. Smelting aluminum ingot can be complex, simple, look at the investment, the most simple coke furnace, a graphite crucible on the line, slow fire simmer.
Q:How to make the aluminum liquid in the round graphite crucible solidified without holes in the middle?
Aluminum water is melted and silicon is added. It should be noted that the surface of the aluminum should be cleaned before making the silicon. The broken silica fume should not be added, and the process of mixing silicon should be properly stirred. After a good silicification, a certain amount of aluminum ingot is used as a cooling material, because the temperature of the silicon will be higher, and the cooling material will be higher.
Q:Can waste circuit boards be recycled?
Silver is also one of precious metals. The recovery of silver from waste liquid is as follows:The waste liquid is adjusted by 20% sodium hydroxide, and the pH value is between 8-9. Then sodium sulfide solution is added to precipitate the silver sulfide;(1): +2Na+: 2Ag+Na2S==Ag2S(2) water washed silver sulfide precipitate to residual sulfide, filtered water, the silver sulfide in the crucible, heating to 800-900 DEG C for desulfurization, remove the cooling.(3) to 100 (weight) silver slag, add borax 10, sodium chloride 5 mix and then burning to crude silver crucible.
Q:How to select and use the carbon graphite for machinery? What items should we pay attention to?
Selection must be based on the working conditions of the equipment, taking into account the pressure, wire speed, medium, and grinding materials and other factors, if necessary, after the test selected appropriate.
Q:Why does the graphite crucible used for molten gold add a quartz coat?
The melting point of gold is 1063 degrees Celsius. At this temperature, graphite reacts with oxygen in the air to produce carbon dioxide. The quartz coat may be used to prevent leakage of graphite crucibles
Q:What is the main function of graphite?
As a conductive material: used for manufacturing the electrode, carbon nanotubes, carbon brush, and the positive electrode of the mercury rectifier in the electrical industry, graphite gasket, telephone parts, TV tube coating etc..
Q:Which crucibles are available for melting sodium hydroxide?
Graphite crucibles and metal crucibles can be usedA porcelain crucible can not be used because of its silicate content, which reacts with NaOH and damages it.
Q:Can the medium frequency furnace be made of silicon carbide crucible?
Glass is non-magnetic, can not be magnetic induction heating. And the silicon carbide crucible can not be heated because of the magnetic induction heating. So, no way.
Q:Graphite grinding out of soy milk foam, how to foam?
Don't skim it. Cook it over a little fire and you'll disappear!The soya bean milk machine is equipped with a strainer, and you can throw it away when you pour it out.Graphite graphite products - graphite processing - graphite crucible - Graphite tableware for you to answer.
Q:Aluminum graphite crucible for iron crucible which is good
The graphite crucible can be heated by coke, and now the graphite crucible is faster than the iron crucible and higher than the iron crucible. If it is graphite crucible used in electric furnace, some manufacturers use it for about one year.
