It is shown that it is expedient to apply thermal spray coatings to the working surface of the narrow walls of continuous-caster molds in order to improve the quality of the cast semifinished products. It was confirmed experimentally that the application of such coatings decreases the number of longitudinal, transverse, and reticular cracks on the surface of slabs, which in turn increases usable output in the subsequent rolling operations.
