Properties: The coefficient of thermal expansion is small, the resistance coefficient is low, and the mechanical strength is high.
Brief introduction: Petroleum coke and pitch are dehydrated and melted in the melting tank, then added to the kneading pot and kneaded according to the proportion, and then formed and calcined. It has the characteristics of low resistivity and is used as a conductive material in electric furnace equipment such as ferroalloy furnaces and calcium carbide furnaces .
Production Process
Petroleum coke and pitch are dehydrated and melted in a melting tank, added to a kneading pot in proportion to knead, and then shaped and calcined.
