Description

Characteristics of a graphite crucible:

The graphite crucible has good thermal conductivity and high temperature resistance. When used at high temperatures, the coefficient of thermal expansion is small, and it has a certain resistance to deformation during rapid heating and rapid cooling. It has strong corrosion resistance to acids and alkaline solutions, as well as excellent chemical stability. It is widely used in the smelting of non-ferrous metals and their alloys in the modern metallurgical industry and in the insulation of non-ferrous metals in non-ferrous metal casting and injection molding. It is used in the production of automotive, motorcycle aluminum alloys. wheels, spark plugs, cylinder heads, copper alloy timing rings and other parts.

Physical and chemical characteristics of clay crucible:

Refractoriness: ≥ 1630 ℃

Carbon content: ≥ 38%

Apparent porosity:≤ 35%

Volume density:≥ 1.6 g / cm3
