The effect of electrochemical inoculation of 7Kh2SMF steel by rare earth and rare metals during electroslag remelting was studied. The remelting was done in a crystallizer under flux with additions of rare earth metal oxides of the cerium group and rare metals such as niobium, tantalum, and zirconium. Steel inclusions were measured by an ocular rule and divided according to their composition into oxides, sulfides, oxysulfides, and nitrides. The inoculation of rare earth and rare metals caused a change in the type of carbon distribution in steel, reduced oxide and nonmetallic inclusions, and smoothed the structure over the ingot cross section.
