In the converter steel-making processing, a lot of steel-slag in melting state is produced. Traditionally in metallurgy, when slag stopping balls are used, the balls drop inside and slide-roll to the furnace dump-mouth, because of the movement of the slag stopping balls is without a definitive direction to the tapping hole,so the molten steel can not outflow completely and affect the slag splashing,the cost is increasing.The efficiency of the slag-stopping ball is less than 70%. Using the slag-stopping plug in tapping process, its efficiency can be improved 98%, with slag thickness ≤20mm.
