The paper presents technological and configuration solutions for new complexes of cast iron desulphurization by mono-injection of magnesium in the medium-size ladles (80–130 tons of cast iron). As a result, cast iron desulphurization (up to ≤ 0.001% of sulfur content), ladle slag correction, and cast iron purification from sulfur are achieved. Magnesium injection is provided by two-nozzle lances at the magnesium supply rate of 6.5 to 16.0 kg/min. The “free board” height of the ladles is 0.20 to 0.55 m (0.42 m, on average). The sulfur content of cast iron decreases from 0.025–0.094% to ≤ 0.001–0.002%. The actual technological parameters and main process characteristics are provided based on the results of commercial cast iron processing runs at 4 lately commissioned desulfurization complexes.
