Numerical Study of Enhanced Stirring Mechanism of a Novel Rotatable Lance in Side-blown Smelting Furnace
摘要
Abstract
Injection characteristics of side-blown lance in a bath smelting furnace directly govern reaction intensity and smelting efficiency.In this study,stirring enhancement mechanism of a novel side-blown lance with an adjustable rotation angle was investigated by computational fluid dynamics(CFD),and structural parameters of the lance were optimized.A volume-of-fluid(VOF)multiphase flow model coupled with the realizable k-ε turbulence model was employed to conduct transient simulations of gas-liquid two-phase flow in an oxygen-enriched side-blown smelting furnace.Influence of lance rotation angle(0°,15°,30°,45°,and 60°)on flow field and mixing performance of the molten bath was analyzed.Results indicated that lance rotation angle exerted a nonlinear control effect on bath hydrodynamics.A moderate rotation angle(around 30°)effectively enlarged gas-induced disturbance region,accelerated interfacial renewal,and improved the uniformity of bath stirring.In contrast,either a non-rotating angle(0°)or an excessively large rotation angle(60°)led to pronounced flow drift and deteriorated local mixing.Overall,the proposed side-blown rotatable lance,through appropriate optimization of rotation angle,can enhance bath stirring while simultaneously ensuring furnace lining integrity and prolonging lance service life.The findings provided a theoretical basis and engineering guidance for lance design and optimization in large-scale oxygen-enriched side-blown smelting furnaces.关键词
