Abstract:In view of the high rejection rate of the anode plates of the tilting furnace, a statistical analysis of the rejected anode plates found that the taper and heaviness of the anode plates are the main reasons. The factors causing the taper and heaviness of the anode plate were investigated and analyzed on site, and the main influencing factors were determined to be the spraying effect of the copper mold and the service life of the casting ladle. Afterwards, by designing an automatic mobile spraying mechanism and replacing the refractory materials of the casting ladle, the rejection rate was greatly reduced, thereby reducing the cost of refurbishing the anode plate,achieving the expected goal, and stabilizing the rejection rate within a controllable range.
