Electrode Paste

Trapezoidal electrode paste

The electrode paste is made by dehydrating and melting petroleum tar pitch in a melting tank, adding it to a kneading pot in proportion to kneading, and then forming and calcining.

Electrode paste 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.

Electrode paste can be divided into goose egg shaped electrode paste, trapezoidal electrode paste, and cylindrical electrode paste according to the shape.

Materials:Calcined Anthracite Coal,Calcined Petroleum Coke,Anode Scrap,Coal pitch,Coal Tar,Graphite Powder.
