Crucible is a kind of refractory graphite crucible which is mainly used for smelting special alloy steel, melting non-ferrous metals and its alloys, which is made from crystalline natural graphite as main material and plastic refractory clay as binder, and is made by mixing with different types of clinker. Graphite crucible is an integral part of refractory material for the performance and use of the product.

Induction furnace crucibles can be divided into graphite crucibles, clay crucibles and metal crucibles. There are three kinds of graphite crucibles, namely, general type graphite crucible, special type graphite crucible and high purity graphite crucible. Due to different properties, uses and conditions, different types of graphite crucibles are used in different raw materials, production methods, technology and product models and specifications.

The main raw material of graphite crucible is crystalline natural graphite. Therefore, it maintains the original physical and chemical properties of natural right ink.

That is, it has good thermal conductivity and high temperature resistance. In the process of high temperature use, the coefficient of thermal expansion is small, and it has certain strain resistance to the rapid heat and quench. It has strong corrosion resistance to acid and alkaline solution and has excellent chemical stability.

Crucible has many types and specifications, and can be selected arbitrarily without the limitation of production scale, batch size and smelting material variety. It has strong applicability and can ensure the purity of the melted material.

Graphite crucible, because of its excellent properties, has been widely used in induction smelting furnace and smelting of non-ferrous metals and its alloys in metallurgical, casting, mechanical, chemical and other industrial sectors. And has a good technical and economic effect.
