Silicon Carbide Crucibles are made out of silicon carbide and graphite utilizing tar pitch or other synthetic resins as bonding materials. Silicon Carbide Crucibles are highly refractory products used for melting ferrous and non-ferrous metals and alloys in the foundries because of its superb inherent properties such as , low thermal expansion, good thermal conductivity, resistance to thermal shocks, resistance to wetting to molten metals, etc. when compared to clay bonded graphite crucibles. Silicon Carbide Crucibles are mostly used for melting non-ferrous precious metals such as Brass, Copper, Aluminium, Gun metal, Bronze, Zinc, Zinc Oxide, Silver, Gold, Kalaya, etc. Our Silicon Carbide Crucibles support all kinds of furnaces such as Oil fired furnace, Electric furnace, Gas fired furnace, Coal fire furnace, Induction furnace, Diesel fired furnace
How to select the right crucible for your application :
The best method for selecting the right crucible includes the detailed study of your operations. One must document and quantify all aspects of melting, holding and metal holding process :
- The capacity, dimensions and type of your furnace
- The specific alloy or range of alloys you melt
- The melting and/or holding temperatures you maintain
- The temperature change rate the crucible will experience
- How the crucible is charged
- The fluxes or additions used
- Degassing or refining processes
- How slag or dross is removed
- How the crucible is emptied.
