Research on Composite Slag Dam Cast with Magnesia Castables and Alumina Magnesia Castables

To enhance the service life of magnesia based slag dam,composite slag dam was designed to be cast with alumina magnesia castables in slag line and magnesia castables in molten steel zone.Workability of the magnesia castables for the slag dam was improved and a suitable vibration shaping method was adopted to combine it with alumina magnesia castables.The result shows:(1)workability and setting performance of magnesia castables can be improved to match with alumina magnesia castables by adjusting setting ret...
