Abstract
Investigation of the influence of the modification with metal nanopowder materials on the quality of slab continuous casting showedthat the introduction of an intermediate ladle MNLZ powder tapes fi lled with titanium carbonitride reduces the segregation of chemical elements in the cross section, increases its chemical and structural homogeneity, meduces zone of the dendritic structure of the ingot, reduces development macrostructure defects, increases the density and mechanical properties of cast steel.
