Product Description
Product Description
The silicon carbide graphite crucible is made by adding silicon carbide particles of varying content to the raw material of the graphite crucible. For example, the content is 50%, 24%, and other different content. Of course, it can also be based on the different requirements of customers. Custom-made graphite crucibles with varying amounts of silicon carbide.
Silicon carbide crucible is mainly used in metallurgy, casting, machinery, chemical industry and other industrial sectors, is widely used in alloy tool steel smelting and non-ferrous metal and its alloy melting, and has better technical and economic effects.
> Fast heat conduction: because silicon carbide graphite crucible uses high thermal conductivity of graphite and other raw materials, shorten the melting time, save energy; In addition, the use of high thermal conductivity materials, dense tissue, low apparent porosity, fast thermal conductivity.
> Long life: compared with ordinary clay graphite crucible, the life can be extended by 3-5 times.
> Strong heat resistance impact: graphite crucible heat resistance impact function is strong, for hot and cold, not easy to break; Can withstand the thermal impact strength , so any process can be assured.
> Corrosion resistance: strong corrosion resistance to molten soup; The average fine matrix design delays the corrosion degree of the crucible.
> Anti-adhesion: Because graphite is not easy to adhere to the characteristics of molten soup, so the penetration and adhesion of molten soup is less
> Metal pollution is very little: strict control of material composition, to ensure that the graphite crucible is not polluted to metal when dissolving; The material design takes into account the relationship with the metal to be smelted and the characteristics of the process, and introduces little or no harmful impurities.
> Energy conservation and environment protection:Fast heat conduction can save a lot of fuel and reduce exhaust pollution.
> High strength: selection of high-quality materials, high pressure pressing, combined with fair, high temperature strength, scientific product modeling, high pressure capacity. Good anti-cracking function. So it maintains the original physical and chemical properties of natural graphite.
> Oxidation resistance: antioxidant design, and the use of high purity raw materials, protect graphite; High oxidation resistance is 5-10 times of ordinary graphite crucible.
> Less viscous slag: less slag hanging on the inner wall, greatly reduce the thermal resistance and the possibility of expansion and cracking of the crucible, always maintain large capacity.

Company Profile
Packaging & Shipping
The smelt soup in the crucible should be cleared out when the furnace stop working, in order to avoid molten soup solidification and will be expanded when fire to reheat, and affect the service life of crucible or even burst.
The graphite crucible should be protected from moisture. The warehouse for storing graphite crucibles should be dry and ventilated, and the temperature should be kept between 5ºC~25ºC, and the relative humidity should be 50-60%. The crucible must not be stored on brick soil or cement floor to avoid moisture.
In order to protect the glaze layer of the crucible, handling crucible must be very careful, to avoid knocking, collision or falling, we can't put the crucible on the ground and rolling to transport. Once the glaze layer of crucible is damaged, it will lead to oxidation and aging of crucible easily in the process of use. The crucible should be handled carefully in a padded cart (or other suitable conveyer).
Our company use rope, rubber, moisture-proof plastic paper, shockproof to pack the crucible, and according to customers' needs, we can customize wooden cases, export packaging cartons, paper tubes, etc., to ensure that the crucible wouldn't be damaged in transit.
