The aim of the researches was to determine the influence of the size of high - carbon ferrochromium grain (which was used to make the pad) on the quality of the composite layer on the steel cast. This kind of cast was obtain by pouring the mould with the pad placed on the chosen surface with liquid metal. As thick as possible composite layer without any defects and discontinuity was required. Both good quality and required thickness of surface composite layer depend on many factors. The pouring temperature, module of cast solidification, size and shape of the cast are the most important ones. The suitable graininess of pad material is also significant parameter. The conducted researches allowed to take the suitable graininess of the pad material which improved the quality of the surface composite layer.
