Abstract
Side-blown smelting technology has been widely adopted in the copper smelting process. In this study, the stirring uniformity of molten bath and the smelting efficiency of the copper smelting process was improved by a computational fluid dynamics method. Simulation of the gas–slag–matte three-phase flow in the furnace was performed by the volume of a fraction multiphase model coupled to a realizable k–ε turbulence model. The flow field can be divided into five zones, high-speed injection, strong-loop, weak-loop, gas overflow and separation, and settlement zones. Three improved gas injection modes, including oblique, horizontal staggered, and vertical staggered, have been proposed to improve the flow field of the weak-loop zone in the center of the molten bath. Of these methods, the oblique injection mode showed the best improvement effect. The stirring intensity and the slag splashing amount were nearly twice and only one-quarter of the original condition, respectively.
