MELTING METHOD OF FERROTITANIUM Russian patent published in 2009 - IPC C22C33/04 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy field. Particularly it relates to production of ferroalloys by aluminothermy process. In the method in the capacity of titanium-bearing raw material it is used liquid titanic slag, it is mixed metallothermic part of charge, consisting of iron-ore concentrates, aluminium powder, lime and ferrosilicium in relation 1:(1.09-1.18):(0.27-0.33):(0.08-0.09) agreeably, in amount 126-146% of titanium slag mass, then it is mixed and penetrate main part of charge, consisting of iron-ore concentrate, lime and aluminium powder in relation 1:(0.1-0.29):(0.43-0.46) agreeably, in amount 15-25% of titanium slag mass. In the capacity of titanium-bearing raw material it is used liquid titanic slag with content 85-95% % TiO₂ at temperature 1700-1850°C.

EFFECT: reduction of aluminium consumption for melting ensured by usage of liquid titanic slag, and also receiving of titanium and aluminous semi-product for melting of synthetic slag.
