Silicon carbide graphite crucible for melting metal

  The Silicon Carbide Crucible for melting metals and light alloys are manufactured with a silicon carbide mixture on the basis of graphite. Our silicon carbide graphite crucible is ideal for the melting of aluminum, copper and etc. It is a container applied to hold metal for smelting in a furnace and it can withstand the extreme temperatures encountered in smelting metals. The crucible material must have a much higher melting point than that of the metal being melted and it must have good strength even when white hot.

  Our silicon carbide graphite crucible have two forming ways: the isopressing forming and Spin-forming.

  The features of silicon carbide graphite crucible compared with normal clay-crucible:Long working lifetime: its working lifetime is increased 3-5 times over normal clay-crucible due to the compact body formed under high pressure; High thermal conductivity: high-density body with low apparent porosity greatly improve its heat conductivity, the thermal conductivity remains stable throughout their usage;New-style materials: new heat conduction materials ensure faster heat transference, reduces adherent slag and pollution, the moisture does not affect them at all and, therefore, they should not be preheated or annealed, they always go to the fire as they leave the packing, without any thermal precaution;Excellent corrosion resistance at high temperature.: better anti-corrosion than normal clay-crucible;Resistance to oxidation: advanced process dramatically improves its oxidation resistance, which ensure persistent heat conductivity and long working lifetime,their shape and sizes do not alter through usage.

  We usually use the size no. to represent melting capacity of copper in kilo. The silicon carbide graphite crucible is suitable for melting such metals as copper, gold, silver, zinc, Aluminium, lead .etc. We also can customize the silicon carbide graphite crucible for the customers according to the detailed requirements.
