tundish slag dam types and features


image

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 .
