1.Introduction

     The material of graphite crucible  can be divided into artificial graphite,clay bonded graphite, and carbon bonded graphite.Artificial graphite crucible is made of graphite electrode as material and made out.

     Clay bonded graphite, the main ingredient is natural crystal graphite and clay Now only used in small amount of high-temperature melting of cast iron, cast steel melting and melting of precious metals.

     Carbon bonded graphite, the main ingredient is natural crystal graphite and silicon carbide. Mainly used in  the melting of  the majority of non-ferrous metals such as copper alloy and aluminum alloy.

2.Property

     Graphite crucible with good thermal conductivity and high temperature resistance, at high temperature in use process, small thermal expansion coefficient, the thermal shock, quenching has certain strain resistance. Of acid and alkaline solution of strong corrosion resistance, excellent chemical stability.

3. Function

     Graphite crucible, because has more excellent performance, so in metallurgy, casting, machinery, chemical and other industries, has been widely used in alloy tool steel smelting and smelting of nonferrous metals and their alloys. And has a good technical and economic effect.
