The main raw material of graphite crucible is crystalline natural graphite. Therefore, it maintains various physical and chemical properties of natural graphite.
Graphite crucibles have good thermal conductivity and high temperature resistance. During high-temperature use, their coefficient of thermal expansion is small, and they have certain strain resistance to rapid heating and cooling. It has strong corrosion resistance to acidic and alkaline solutions and excellent chemical stability.
Graphite crucibles, due to their excellent properties, are widely used in industries such as metallurgy, casting, machinery, and chemical engineering for the smelting of alloy tool steel and non-ferrous metals and their alloys. And it has good technical and economic effects.
Precautions for using graphite crucible:
(1) Can be directly heated, cannot be rapidly cooled after heating, remove with crucible pliers.
(2) Place the crucible on a mud triangle or graphite pad when heated.
(3) Stir during evaporation; Use residual heat to steam dry when almost dry.
The application scope of graphite crucible: melting various non-ferrous metals such as gold, silver, copper, aluminum, lead, zinc, as well as medium carbon steel and rare metals.
Supporting furnace types: coke furnace, oil furnace, natural gas furnace, electric furnace, high and medium frequency induction furnace, etc.
