Catsable for Slag line

The castable for slag line has the properties other than stable high temperature performance, it mainly sustain the high temperature erosion of slag, and sustain the thermal shock, washing-out, abrasion over and over again from molten iron and slag. Of course, reasonable design is very important too.
