The quality of steel and continuously cast semi-finished products largely depend on the degree and control of the interaction between slag, gas, and refractories, with the steel melt. In this work, through the analysis of some samples from a used refractory lining of a tundish, with the help of optical microscopy, the wear of the refractory layer was highlighted, due to the erosion and infiltration of steel microparticles into the pores of the lining. The examination of the samples was carried out in the interface area, metal-shotcrete, shotcrete-concrete, and the area with refractory concrete.
