Electrode paste is a conductive material supplied to electric furnace equipment such as ferroalloy furnaces and calcium carbide furnaces. The influence of the quality of the electrode paste on the electrode is:

1. The ash bonding strength of the electrode paste is poor, and the bonding strength is worse in the place where the ash content is concentrated. This place consumes fast and is easy to be mechanically strained and cause hard fracture. Therefore, the ash content should be maintained at an index of ≤3.

2. If the softening point of the electrode paste is low, the coking value after sintering is low, and the strength of the motor is also poor, which may easily cause electrode accidents.

3. The high resistivity of the electrode paste indicates that the graphitization of the electrode paste is low, the conductivity is poor, and the oxidation resistance of the electrode is poor, and the electrode with strong rigidity after firing is also easy to break.
