Tundish gunning material is in direct contact with molten steel, so the following requirements must be met:
1) It has good slag erosion resistance and slag permeability resistance
2) It has good high temperature performance, high fire resistance, certain high temperature strength and chemical stability, and does not produce secondary oxidation and pollution with liquid steel
3) It has good thermal shock resistance and volume stability
4) It has low thermal conductivity and good thermal insulation performance
5) The construction is simple and can be quickly baked and put into use
6) It is easy to separate from the permanent layer during removal to reduce damage to the permanent layer
The tundish gunning material supplied by our company has the above properties. It is now supplied to large iron and steel plants at home and abroad with good application effect
