Abstract
The prospects of using barium-bearing master alloys for the deoxidation and modification of wheel steel are considered. The oxygen solubility is thermodynamically calculated in carbon-containing wheel steel melts for various deoxidation versions, and the results of laboratory and industrial experiments on the deoxidation and modification of railroad wheel steel are discussed. Industrial experiments performed at OAO Vyksunsk Metallurgical Works show that the use of barium-bearing master alloys for the deoxidation and modification of wheel steel under mass production conditions leads to a decrease in the nonmetallic inclusion contamination of a metal, a decrease in the rejection of solid-rolled railroad wheels, grain refinement in a metal, and an increase in its mechanical properties.
