METHOD OF ALUMINO-THERMAL PRODUCTION OF FERRO-TITANIUM Russian patent published in 2008 - IPC C22C33/04 C22B5/04 

FIELD: metallurgy.

SUBSTANCE: invention refers to metallurgy of high-melting rare metals, particularly to metallurgy of titanium, and can be used at production of ferro-titanium for alloys on base of titanium and structural items. The method consists in out-of-furnace alumino-thermal reduction; ore titanium concentrates are used as titanium containing element of charge; elements of charge are mixed till obtaining the ratio of iron and titanium oxides 1:(1.0÷3.0) of wt, calcium oxide 0.2÷0.5 from the total weight of titanium and iron oxides and aluminium till obtaining ratio of total contents of titanium and iron oxides to aluminium as 1:(0.45÷0.55). Before reduction charge is heated to the temperature of 800-1000°C in inert medium and held to equalise temperature in charge volume; the process of reduction is initiated by firing of charge followed by heating turn off.

EFFECT: invention facilitates reduction of power consumption of process, it also allows avoiding of metallic titanium use and it increases extraction into finished product.
