The slag stopper is the same as the slag stopper ball. It is used for slag stopper at the end of converter tapping. It is composed of a plug head and a plug rod. The material of the plug head is similar to that of the slag ball. Please refer to the slag ball for the index. When in use, the slag-blocking car is used to put it into the steel outlet. Due to the guiding effect of the plug rod, the throwing rate is greatly improved compared with the slag-blocking ball. The product has been successfully applied in Shagang, Huaigang, Hongyang and other steel mills.
