Interaction of Exogenous Nanoparticles of Refractory Phases with Surfactant Impurities of Non-ferrous Metals in Iron Melts in Contact with Refractory Material

Тhe results of the heterophase interaction of nanoparticles of refractory phases with iron melts containing harmful impurities (sulfur, antimony, tin, and copper) are studied and generalized. It is shown that the degree of the removal of impurities (~0.05 wt %) in the Fe–S, Fe–Sn, Fe–Sb, and Fe–Cu s...

Description
Summary:Тhe results of the heterophase interaction of nanoparticles of refractory phases with iron melts containing harmful impurities (sulfur, antimony, tin, and copper) are studied and generalized. It is shown that the degree of the removal of impurities (~0.05 wt %) in the Fe–S, Fe–Sn, Fe–Sb, and Fe–Cu systems after the introduction of nanoparticles ranges from 10 to 37 rel %. As a result of the interaction of nanoparticles with impurities of the metal melt, the formation of ensembles with new surface properties is proposed. It is shown that the redistribution of ensembles in the melt and their removal to the phase interface can be represented as a two-stage process.
