Self-flowing gunning mass
Using the fused magnesia and magnesia-calcium sand as the main raw materials of self-flowing gunning mass, and the composite carbon and ceramic combination method is used for the heat repair of the converter bottom, large and small surface, slag line and other parts.
It has the advantages of good fluidity, short sintering time (less than 30 minutes), low smoke pollution and convenient construction.
The hopper is used for feeding and the amount of addition depends on the size of the furnace and the degree of erosion.
