Electrode paste
Söderberg-type electrode paste is produced from calcined petroleum coke (or calcined pitch coke), calcined anthracite, coal tar pitch and other additional materials. Electrode paste is used for the manufacture of carbon electrodes for electric arc furnaces designed for a production of various types of ferroalloys, calcium carbide, etc.
