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.

Q:Can the graphite crucible be rinsed with water?
It is not recommended to wash with water. If you rinse with water or get wet, you must bake for about 20 hours before use, until it is completely dry. Otherwise, the graphite crucible will burst because of heating. The graphite crucible has good thermal conductivity and high temperature resistance, and the thermal expansion coefficient is small in the process of high temperature use, and has a certain anti strain property for hot and cold quenching. The corrosion resistance of acid and alkaline solution is strong, and it has good chemical stability. In metallurgy, casting, machinery, chemical and other industrial sectors, it is widely used in smelting of alloy tool steel and smelting of nonferrous metals and their alloys. And has better technical and economic results.
Q:Graphite can react with alkali in high temperature
At high temperatures, graphite is more easily oxidized by oxidizing chemicals to produce carbon dioxide or other carbon oxides.
Q:How long is the service life of the cast iron crucible?
Now basically no trial of cast iron crucible, graphite crucible is a cast iron crucible, the general can only use a month or so, now the shortest graphite crucible can be used for half a year, Wuxi branch cast Trade Co., a cast card graphite crucible
Q:What are the technical specifications of graphite crucibles?
Crucible; physical and chemical index; standard parameter; test dataThe refractoriness is 1680 degrees, and the refractoriness is 1685Carbon content 38%, carbon content 41.46%Porosity less than 35% porosity is less than 32%Volume density 1.6g/cm3 volume density 1.71g/cm3The above data are referred to Qingdao Huatai graphite, hope to adopt, thank you.
Q:Will the friction powder of the graphite sliding bearings rust?
Graphite bearings do not charge, but if the connecting parts such as iron and other materials will rust, unless the internal device is all vacuum, which may be exposed to graphite bearings. In short, graphite products do not rust, but do not rule out inducing factors.
Q:Who knows the method for determining the total iron content in iron ore?
Iron ore is the basic raw material of iron and steel industry, can be smelted into pig iron, wrought iron, iron alloy, carbon steel, alloy steel, special steel, etc.. Used in blast furnace iron ore, the total iron TFe (total iron content) = 50%, S = 0.3%, P = 0.25%, Cu = 0.2%, Pb = 0.1%, Zn = 0.1%, Sn = 0.08%, and mined the original iron ore grade is only 20% ~ 40%. by enrichment, can be the ore grade is increased to 50% to 65%. China imports large quantities of iron ore from abroad every year.
Q:Melting the iron in the graphite crucible. Does the graphite in the crucible turn into carbon and it melts into the steel?
In addition to carbon, charcoal contains hydrogen, oxygen, nitrogen, and a small amount of other elements. Carbon in charcoal is not a transition crystal like graphite, but amorphous carbon and no C-C covalent bonds. Charcoal ignition is 320-370 DEG C, the general fire than the high temperature, so the charcoal can be lit.
Q:The biggest problem with graphite crucibles must be to use in a vacuum or a reducing atmosphere
So it won't do him any harm. He must be in the electric stove to prevent air from entering. The gas stove needs a blower to blow it, that's because he can burn out the air!
Q:What is the use of an iron crucible?
When solids have to be heated by fire, the crucible must be used.
Q:What are the main changes in graphene supercapacitors?
The production of letter Ruida graphite thermal field, graphite mold, isostatic graphite, high purity graphite, EDM graphite, graphite crucible, SPD special graphite sheet, graphite powder, graphite, graphite bearings, Shi Mohuan screws, various graphite elctrodes have many customers at home and abroad, the products are widely used in solar photovoltaic, semiconductor, electronics, mold EDM, metallurgy, chemical industry, nuclear industry and other industries of quartz. Company to strict quality management, perfect after-sales system to win the trust of customers, has become China's well-known graphite products suppliers.
