Research of Gas–Liquid Multiphase Flow in Oxygen-Enriched Bottom Blowing Copper Smelting Furnace

Based on ENFI’s self-developed bottom-blowing continuous copper smelting process, the normal operation bottom-blown copper smelting furnace is the research object. Based on the determination of the physical parameters of the slag phase and matte phase in the furnace, the bottom-blow furnace model consistent with the actual bottom blowing system is established by using the commercial software platforms. The VOF multiphase flow model and the standard k−e turbulence model are used to simulate the three-phase flow process of gas-slag-matte in the furnace. The gas–liquid two-phase flow law in the furnace, the velocity field of each phase in the furnace, and the splashing mechanism of the melting furnace are analyzed. The characteristics of each flow region in the furnace are obtained. This study can also provide a reference for the design and operational system formulation of the bottom blowing furnace.
