In this work the results of research connected with the problem of determination of the temperature at the beginning of the alloy layer forming process on the steel cast were presented. It was shown that diffusion of chromium, carbon and iron, between the material of the premould made of grainy, high – carbon ferrochromium and the cast steel, has an influence on the surface alloy layer forming process. There was an attempt to determine the liquidus and solidus temperatures for ferrochromium. Additionally, the researches were carried out with the purpose of determination of the time of alloy layer forming process.
