EAF repair part

The working conditions of each part of the lining of EAF are different, and the damage is also different. The main parts of the lining damaged are as follows:
Furnace wall slag line, severely damaged by high-temperature arc radiation, chemical erosion and mechanical erosion of slag and steel, and oxygen blowing operations.
Slag line hot spot, in particular, the 2# hot spot is also severely corroded by the influence of high arc power and off-arc, and the degree of damage at this point is often the basis for lining replacement.
Near the taphole, it is also easy to thin due to the erosion of slag steel.
Both sides of the furnace door, it is often damaged by the effects of rapid cold and rapid heat, scouring of flowing slag, and collision between operations and tools.
