The purpose of the study: to increase the technical and economic indicators of steel and foundry production. Research methods and equipment: laboratory installation for experimental study of viscosity of metal melts by the method of damping torsional vibrations, high-temperature microscope MNO-2, physical and mathematical modeling. Experimental studies of the thermophysical properties and toughness of steels in laboratory installations have made it possible to obtain practical recommendations for spraying tool steel ROM2SF-10MP, as a result of which the yield of suitable powder increased by an average of 10%. The use of silicon carbide as a deoxidizer in converter production will reduce the consumption of carburizer and improve the technical and economic performance of production. Optical method using the MNO-2 microscope sets the melting temperature ranges of fluxes used in special electrometallurgy, which allows us to recommend for use in the production of low-fluoride fluxes AN-14, AN-15 and AN-15M. Compositions of fluorine-free refining slags for ladle processing of steel with high rare fluidity have been developed. The higher strength of the new foundry mixtures developed allows to reduce the consumption of binders and to obtain better quality castings. Calculations of the process of bubbling mixing of molten steel with argon in a ladle showed the advantages of blowing argon everywhere into the bottom lance.
