发明名称 HIGH TITANIUM FERRO ALLOY PRODUCED BY TWO STAGES REDUCTION OUT OF ILMENITE
摘要 FIELD: metallurgy. ^ SUBSTANCE: invention refers to high titanium ferroalloy, produced by two stages melting in electric furnace; alloy is used as alloying component at production of steel with high level of physic-mechanical properties. For producing of ferroalloy the charge prepared out of ilmenite, iron and/or steel scrap, crushed electrodes and/or coke, lime and/or lime stone is used; then slag containing titanium oxide and part of iron melt on the first stage are withdrawn; a consumable electrode in a steel coat is melted under the layer of flux; the said electrode contains crushed slag of the first stage and aluminium as filler. Ferro alloy contains components at a following ratio, wt %: titanium 68.02-78.7; iron 19.32-30.0; impurities to 1.98. ^ EFFECT: invention facilitates production of finished product in form of compact commodity ingot of ferrotitanium with specified contents of basic component. ^ 2 ex, 2 tbl
