Solutions to problems of reduction & cleaning of converter slag encountered in industrial application were presented in detail. Aiming at modification of the existed 60 t converter, optimization of kinetics condition and heat balance calculation for slag reduction and cleaning were conducted. Based on the calculation results, solutions were proposed which also includes some corresponding measures for other possibly-encountered problems in the slag reduction process. It is found that with the following parameters, such as lance with diameter of 30 mm at an angle of 14°, injecting reducing agent at a rate of 30 kg/min, diesel dosage at the rate of 135 L/h at the stage of heat preservation, and at the rate of 500 L/h during the reduction, the implementation of this scheme in the industrial production resulted in the reduction of Fe3 O4 at a rate of 62.9%, and copper content in converter slag decreased at an average rate of 63.5%.
