Crucible of the model specifications are more in the application from the scale of production, batch sizes and varieties of constraints melting material, can choose the applicability of the strong, and guarantee the purity of the material by melting. 
 Graphite crucible, with their excellent performance over, so in metallurgy, casting, mechanical, chemical and other industrial sectors, is widely used in smelting and alloy tool steel smelting of nonferrous metals and alloys. And has a good technical and economic effect.
