In this article, steel production enterprises, as a rule, do not have special
equipment for steel processing. Under such conditions, practice shows that the only and very
effective way to improve the quality of steel is the treatment of liquid metal with special complex
modifier alloys in a steel-pouring furnace. Modification of metals and alloys (its diversity) is a
deep process that actively affects the state of metal solutions during the crystallization period of
their presence by introducing small additives of substances (modifiers) that lead to a change in
the morphology of non-metallic inclusions. A change in the energy state and a decrease in the
contamination of the boundaries of the grains of the metal matrix lead to an improvement in the
mechanical and technological properties of the steel casting.
