SIZE As your detailed requirements.

Graphite blocks are normally used in the flowing field:
*Casting molds for railroad wheels.
*Heat exchangers for chemical industries.
*Electrodes and linings in some industrial furnaces (such as graphitization furnace).
*Cathodes in aluminum electrolysis cells.
Features:

Our graphite blocks have the flowing advantages:
*High thermal and chemical resistance.
*Good thermal conductivity.
*Low coefficient of thermal expansion.
*Minimal wettability to molten metals.
