Gunning
The electric arc furnace gunning is made of fused magnesia and composite binder. It has the characteristics of good adhesion, low rebound rate, easy sintering, erosion resistance and wear resistance. It is suitable for spraying, supplementing, and maintaining the slag line of the electric furnace and the furnace slope.
