Abstract

The invention is applicable in metallurgy for obtaining a ferroalloy with a particularly high titanium content by remelting a melting electrode in an electric arc furnace, supplemented with an electromagnetic system for generating a pulsed magnetic field. The alloy is applicable as a ligature for the production of steel with high physical and mechanical properties. A mixture of rutile, iron and/or steel scrap, carbon powder and/or coke, lime and aluminium powder is used to obtain the alloy. They are melted under a molten layer as a melting electrode in a metal shell. An additional pulsed magnetic field is applied to the molten layer region, which acts, firstly, on the flowing current and, secondly, on the crystallization region, promoting chemical reactions and improving the crystallization structure. In this way, it is possible to obtain an alloy containing components in the following proportions, % by mass: titanium – 70-80%; iron – 12-17%; aluminum – 3-6%, impurities – up to 2.6%.
