Fabrikant van smeltkroezen

Crucibles mainly include silicon carbide crucibles and graphite crucible, which are mainly made of flake graphite and silicon carbide. They have the characteristics of good thermal conductivity, hoge dichtheid, corrosieweerstand, less slag adhesion, hoge mechanische sterkte, oxidation resistance, weerstand tegen thermische schokken, enz. They do not react with molten metals in the smelting process, and are not easy to leak and adhere. They are widely used in the smelting of alloy tool steel and the smelting of non-ferrous metals such as copper, aluminium, and their alloys.
