The impact of chemical corrosion on the durability of tundish working lining based on slurry mix is discussed in this work. The results of chemical and mineralogical analysis in the sample of tundish working layer after lining lifetime are presented. Infiltration of slag effected in a reduced thermal shock resistance resulting in thermal stress on the tundish working lining and causes wear of the impact layer. In order to achieve higher performance in the tundish working lining based on magnesia and to obtain clean steel appropriate measures are proposed.
