What is the reason why the graphite crucible cracks?

Graphite clamp have good thermal conductivity and high temperature resistance. In the process of high temperature use, the thermal expansion coefficient is small, which has a certain strain capacity to acute cold and acute heat, and has corrosion resistance to acid and alkali liquid.

 It has a high strength and a good chemical stability. It is because of its excellent performance, widely used in the smelting of alloy tool steel and non-ferrous metals or other alloys. 

1. When customized graphite clamp pan, ensure that there is no water around the furnace and in the pit in front of the furnace, and irrelevant debris should not be piled up near the graphite clamp.

2. Before customizing the graphite jespan, be sure to check for explosives nearby. When feeding, it must be kept dry. When adding a clamp, we must pay attention to the speed, and keep it slow.

3. Graphite crucible should be checked without crack before use. If there are no cracks, heat to heat above 600 degrees to ensure drying.
