What Is The Working Principle Of Slag Stopping Ball?

Sep. 12, 2018

Aluminum Base Slag Stopping Ball is a ball that blocks the taphole at the end of the tapping to block the slag flowing into the ladle. The shape is a spherical body, and the outer surface of the spherical body is formed with a mesh groove formed of a homogeneous refractory material.

The working principle of slag ball: The principle of slag ball is to use the slag ball density between steel and slag, and block the taphole at the end of tapping to block the slag from flowing into the ladle. The slag blocking ball is generally spherical, and as long as it can meet the process requirements, the structure is simple and the cost is low. However, since the slag ball usually arrives at the taphole in a wave-by-flow manner, the slag ball sometimes cannot smoothly reach the taphole due to the high viscosity of the steel slag. In addition, since the circular slag ball completely falls on the taphole, the probability of premature sealing of the taphole is significantly increased, and the yield of molten steel is lowered, so the reliability of the slag ball is not very satisfactory. Therefore, the current slag cone product has emerged, which can fully meet people's requirements.

Slag ball has the advantages of good slag resistance, high strength, high temperature resistance and good stability. It can effectively reduce the slag content of molten steel in the tapping process and meet the needs of slag tapping.
