【摘要】 采用所构建的铜侧吹熔炼过程多相平衡热力学仿真模型及计算系统，在典型工况条件下计算的产物组成结果与实际产出情况基本吻合，验证了模型热力学分析的可行性，并在此基础上进一步考察氧料比(R_OC)、石灰熔剂率(R_CaO)、石英熔剂率(R_SiO2)、富氧浓度(C_Oxy)、燃煤率(R_Coal)等工艺参数对主要技术指标的影响。结果表明：提高R_OC，渣含铜、铜锍品位、渣含Fe₃O₄、渣中铁硅比和烟气中SO₂浓度升高，而渣含CaO降低；提高R_CaO，渣含CaO升高；提高R_SiO2，渣含CaO和Fe₃O₄均降低；提高R_Coal，除渣含CaO升高外，其它主要技术指标均降低；提高C_Oxy，烟气中SO₂浓度升高。更多还原

【Abstract】 The multi-phase equilibrium thermodynamic simulation model and calculation system of the copper sideblown smelting process were constructed. The results of product composition calculated under typical working conditions were consistent with the actual output, which verified the feasibility of the thermodynamic analysis of the model. On this basis, the effects of process parameters such as oxygen-to-material ratio(R_OC), lime flux rate(R_CaO), quartz flux rate(R_SiO2), oxygen-enriched concentration(C_Oxy), and coal burning rate(R_Coal) on the main technical indicators were further investigated. The results show that as R_OC increases, the copper content, the amount of slag enriched with gangue, the content of Fe₃O₄, the iron-silicon ratio, and the SO₂ content in the flue gas increase, while the CaO content decreases. When R_CaO increases, the CaO content in the slag increases. As R_SiO2 increases, the contents of CaO and Fe₃O₄ in the slag decrease. As R_Coal increases, except for the increase of CaO content in the slag, all the main technical indicators decrease; When C_Oxy increases, the SO₂ content in the flue gas increases.更多还原
