Product Description

Introduction

Graphite crucible is a refractory graphite crucible with crystalline natural graphite as the main raw material and plastic refractory clay as a binder. It is made by combining with different types of clinker and mainly used for smelting special alloy steel, melting nonferrous metals and alloys. . In terms of product performance and use, graphite crucibles are an integral part of refractory materials.
Graphite crucible can be divided into three categories: pure graphite crucible, clay graphite crucible and silicon carbide graphite crucible. In the pure graphite crucible, there are three types of ordinary graphite crucible and high purity graphite crucible. Pure graphite crucibles are mainly used to melt gold and silver and other precious metals. Various types of graphite crucibles have different materials, production methods, process technologies, and product model specifications due to different performance, uses, and use conditions. 
Graphite crucible, because of its excellent performance, is widely used in the smelting of alloy tool steel and the melting of non-ferrous metals and their alloys in metallurgy, casting, machinery, chemical industry and other industrial sectors.

 
Advantages

★Graphite crucible has good thermal stability, small coefficient of thermal expansion, and has certain strain resistance to rapid heating and rapid cooling.
★Graphite crucible has good corrosion resistance and impact resistance to ensure the reliability of product quality.
★Graphite crucible has good chemical stability, resistant to strong acid and alkali.
★Good thermal conductivity of graphite crucible: can greatly shorten the melting time and save energy.
★The ash content of pure graphite crucible is less than 300pp, to ensure that precious metals will not be polluted during smelting.
