Characteristics of graphite crucibles have good thermal conductivity and high-temperature resistance, in the process of high-temperature use, the thermal expansion coefficient is small and has a certain strain resistance to acute hot and cold. Strong corrosion resistance, and strong chemical stability.

The output of domestic graphite crucibles has reached or even exceeded that of the imported crucible, especially the large production enterprises of graphite crucibles in the Yangtze River Delta region. The graphite crucible produced by Ben Hong, as the representative of the domestic crucible, has the following characteristics:

1. The high density of graphite crucible makes the crucible have good thermal conductivity, and its thermal conductivity effect is better than other imported crucibles;

2. Because of the special glaze layer and dense forming material on the surface of the graphite crucible, it has super corrosion resistance and greatly improves the service life;

Graphite crucible graphite composition is natural graphite, with strong thermal conductivity. The heated graphite crucible cannot be immediately placed on a cold metal table, otherwise, it will crack due to rapid cooling.

Crucible is suitable for smelting a large number of alloys. To change the alloy type, it is only necessary to replace the graphite crucible. Other melting methods such as reflector furnaces and non-crucible induction furnaces for melting are suitable for large amounts of melting of a single alloy, if the type of melting alloy changes if the lining refractory is not replaced, metal contamination will occur.
