Dec 19, 2022
1. Ingredients operation
Silica: 300kg; Semi-coke: 190-200kg; Pellet: 50-60kg
2. Smelting operation
Primary current: 250-270A, the three-phase current is kept balanced; the depth of entering the furnace: 1 500-1800mm; evenly feed the material to keep the material surface with good air permeability; correctly handle the phenomenon of stinging and large material collapse.
3. Operation in front of the furnace
Deep plugged holes; frequent cleaning of launders, treatment of false openings; control of the amount of brazing used; ensure that the ladle is fully baked, and the ingot mold is clean and dry
