Abstract

Investigation of the effect of metal modifying with nanopowder materials on the quality of rectangular continuously cast billets, structural shapes and reinforcing bar showed that the introduction of TiCхNy – Fe admixture in tundish ladle of continuous casting machine reduces segregation of elements in the ingot and pollution by non-metallic inclusions, increases its chemical and structural homogeneity. NPI application alters the structure of shapes and rebar; shape, size and topography of the location of non-metallic inclusions; as well as grain refining and improvement of the metalroll mechanical properties.

Keywords

modification, nanopowder inoculators, rectangular billet, density, structure, non-metallic inclusions, structural shapes and reinforcing bars, mechanical properties
