PROCEDURE FOR PRODUCTION OF HIGH GRADE FERROTITANIUM

摘要

FIELD: metallurgy.;SUBSTANCE: invention refers to production of ferrotitanium with contents of titanium 30-70 % from oxide titan containing raw material by aluminothermal procedure in melting aggregate-reactor. Charge is loaded and melted in two stages. Also at the first stage charge is melted at ratio of components to contents of titanium dioxide in charge taken as one. There are produced metallic iron tapped from the aggregate and slag melt. At the second stage on titanium containing slag melt there is loaded charge additionally containing ground ferrosilicon with contents of silicon 65-75%. Part of slag melt oxides and oxides in charge is reduced at ratio of charge components to contents of titanium dioxide equal to 0.7-3.0 from amount of titanium dioxide at the first stage of melting. There is produced ferrotitanium melt with contents of titanium 50-70% which is successively tapped either separately or together with slag melt.;EFFECT: increased through extraction of titanium and production of high grade ferrotitanium from oxide raw material without utilisation of titanium alloy scrap.;2 cl, 1 tbl
