Influence of the quality of electrode paste on electrode

  Electrode paste is a conductive material for ferroalloy furnace, calcium carbide furnace and other electric furnace equipment. What effect does the quality of electrode paste have on the electrode? The editor will explain in detail below:

  1. The ash bonding strength of the electrode paste is poor, and the bonding force in the place where the ash is concentrated is even worse. This place consumes quickly and is easy to be mechanically strained to cause hard fracture. Therefore, the ash index should be kept ≤ 3.

  2. If the softening point of electrode paste is low, the coking value after sintering is low, and the motor strength is also poor, it is easy to cause electrode accidents.

  3. The high resistivity of the electrode paste means that the graphitization degree of the electrode paste is low, the conductivity is poor, the oxidation resistance of the electrode is also poor, and the roasted electrode is rigid, and the electrode is easy to break.
