Graphite powder has a wide range of uses, such as molded and refractory crucibles made of graphite powder and related products, such as crucibles, flask, stoppers and nozzles. Graphite powder has fire resistance, low thermal expansion, stability when it is infiltrated and washed by metal in the process of melting metal, good thermal shock stability and excellent thermal conductivity at high temperature, so graphite powder and its related products are widely used in the process of directly melting metal. The following Furuite graphite editor will introduce you in detail:
The traditional graphite clay crucible is made of flake graphite containing more than 85% carbon, usually the graphite flake should be larger than 100 mesh. At present, the important improvement in crucible production technology abroad is that the type of graphite used, the size and quality of flake have greater flexibility; Secondly, the traditional clay crucible was replaced by silicon carbide graphite crucible, which came into being with the introduction of constant pressure technology in steelmaking industry.
Furuite graphite can also be applied to graphite powder by using constant pressure technology. In clay graphite crucible, large flake graphite with 90% carbon content accounts for about 45%, while in silicon carbide graphite crucible, the content of large flake components of graphite powder only accounts for 30%, and the carbon content of graphite is reduced to 80%.
