Abstract
Abstract. The process of liquid iron desulfurization was investigated in the processing by powdered fl ux (20 % CaO – 60 % Al2O3 – 20 % CaF2 ) with simultaneous hydrogen blowing. The presence of hydrogen, dissolved in the melt, has a positive effect on the desulfurization process, because the process of hydrogen deoxidation of liquid metal increases the completeness of desulfurization process. Desulfurization of liquid iron by slag-forming mixture and hydrogen blowing of melt should be carried out simultaneously.
