A new cast iron desulfurization unit is put into operation in the oxygen converter workshop of Magnitogorsk Metallurgical Combine. Statistically significant linear dependences are established for the degree of cast iron desulfurization on nitrogen injection duration, overall weight of fluidized lime and magnesium, and the weight ratio of fluidized lime and magnesium. An average degree of metal desulfurization of 77.3% is achieved in checking the technology for cast iron ladle desulfurization with injection lasting up to 30 min of fluidized lime and magnesium in a stream of nitrogen with specific consumption of 1.9 and 0.4 kg/ton, respectively.
