Abstract

The invention can be used in metallurgy for the production of an iron alloy 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 can be used 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 the fusible layer as a moving electrode in a metal shell. In the region of the fusible layer, an additional pulsed magnetic field is imposed, 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, mass %: titanium - 70-80%; iron - 12-17%; aluminium - 3-6%, impurities - up to 2.6%.
