A method for deoxidizing steel consists in adding into the ladle of ferroalloys containing silicon, desulfurizing reagents and aluminium, 20... 50 % of which is added along with desulfurizing reagent,, and 50... 60 % is added in the form of bars or ingots after incorporation of desulfurizing reagent and alloying elements. Instead of bars of primary or secondary aluminium added is into the ladle an alloy of aluminuim with iron (ferroaluminium) at an amount of 0.1... 8.3 kg/t of steel taking into account weight parts of carbon in metal and aluminium in ferroaluminium.
