Abstract

Described innovative competitive practice of electric steelmaking in arc furnaces for obtaining bearing rolled section ШX15СГ-В (analogue 1.3520, EN) of freight wagon forged axes (35G, EAN1), castings of truck elements was developed and implemented by Electrometallurgy Department of National Metallurgical Academy of Ukraine in collaboration with JSC “Dneprospetsstal”, JSC “Nizhnedneprovsk Tube Rolling Plant” and others. The results are generalized and analyzed. The new method of steel bath carburization - СSiC-briquettes and results of its application when steelmaking in arc and open-hearth furnaces are presented.
