tundish slag dam types and features
There are different materials of stundish slag dam such as magnesia, high alumina and spinel. The advantages of magnesia slag dam are as follows:
1. It has good thermal shock resistance;
2 Soaked in molten steel, high strength when PO2 content is low;
3.Bring less oxygen content into molten steel , which is 80% lower than that of t high aluminum slag wall dam .
4.Absorbing Al2O3 in the inclusions to form spinel on the surface of slag dam .
