Abstract

A two-dimensional mathematical model of the multiphase flow field during top blowing was created. The model is based on the rotating top-blown furnace of a certain copper plant's lead anode slime. The accuracy of the model was validated by comparing the results with empirical formulas. The study investigated the multiphase flow behavior under production conditions, utilizing the standard k–ε turbulence model and the VOF multiphase flow model. The effects of top-blown operating pressure, nozzle Mach number, lance position, and melt depth on the jet flow have been analyzed. It was discovered that the top-blown operating pressure and lance position have the most significant impact on the refining effect. The optimal operating parameters were determined as follows: operating pressure of 0.6 MPa, nozzle Mach number of 1.5, lance position at 0.5 m, and melt depth of 1.5 m. These can provide guidance for optimizing the production conditions of the lead anode slime rotating top-blown furnace.
