摘　　要：针对"电弧炉+多功能转炉+VOD"三步法不锈钢冶炼工艺,以脱磷为主线,从冶金热力学的角度对该流程涉及的重要工艺环节的可行性,即转炉后期去碳保铬和VOD冶炼过程脱碳脱气等问题进行了理论分析和计算,为不锈钢冶炼全流程磷的控制及脱磷工艺优化提供了理论依据。Aiming at the smelting process of stainless steel using tristep method of 'electrical arc furnace+multifunctions converter+VOD' and centering about dephosphorization, the analyses for the feasibility of several important links in the process chain including decarburation, chromium conservation in the late inverter process and degassing in the VOD process, were carried out from the point of view of metallurgy thermodynamics. A theoretical basis was offered for controlling phosphorus and optimizing the dephosphorization process in the whole stainless steel refining process.
