Description

technical field [0001] The invention belongs to the technical field of conductive materials, in particular to an industrial conductive material and a preparation method thereof. Background technique [0002] Electrode paste is a conductive material for electric furnace equipment such as ferroalloy furnaces and calcium carbide furnaces. According to its use method, it is also a continuous self-baking electrode. The main raw materials for producing electrode paste are anthracite and metallurgical coke. Two different formulations of electrode pastes are currently produced. One is the so-called standard electrode paste. It is widely used in ferroalloy furnaces and medium and small calcium carbide furnaces. This electrode paste uses medium pitch with a softening point of 65-75°C as the binder. Another electrode paste for closed ferroalloy or calcium carbide furnaces. This closed electric furnace requires the electrode paste to have high electrical and thermal conductivity, a...
