Graphite Crucible

Description

Graphite crucible is made of crystalline natural graphite as the main raw material, plastic refractory clay as the binder, and it is made by combining with different types of clinker.

Graphite crucible is made of crystalline natural graphite as the main raw material, plastic refractory clay as the binder, and it is made by combining with different types of clinker. It is mainly used for smelting special alloy steel, melting non-ferrous metals and their alloys. In terms of product performance and use, graphite crucible is an integral part of refractory materials.

Graphite crucibles can be divided into three categories: pure graphite crucibles, clay graphite crucibles and silicon carbide graphite crucibles. In pure graphite crucible, there are three kinds 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 raw materials, production methods, process technologies, and product specifications due to their different properties, uses and conditions of use. A

Graphite crucible, because of its excellent performance, is widely used in the smelting of alloy tool steel and the smelting of non-ferrous metals and their alloys in metallurgy, casting, machinery, chemical and other industrial sectors.

Features

• Graphite crucible has good thermal stability, small thermal expansion coefficient, and has certain strain resistance to rapid heat and cold.
• The graphite crucible has good corrosion resistance and impact resistance to ensure the reliability of product quality.
• Graphite crucible has good chemical stability, strong acid and alkali resistance.
• Good thermal conductivity of graphite crucible: It can greatly shorten the melting time and save energy.
• The ash content of pure graphite crucible is less than 300pp, which ensures that precious metals are not contaminated during smelting.
