Abstract

ABSTRACT Insights into the kinetics occurring during the combined blown (top and bottom blowing) oxygen steelmaking process, particularly at the impact and emulsion zones within separate reactors, can provide a deeper understanding of the refining mechanism in steelmaking. A dynamic model has been developed that can predict the contributions of various refining processes such as decarburization, desiliconization, demanganization, and dephosphorization. The model considers gas–metal interactions at the impact zone and slag–metal–gas interactions at the emulsion zone in an oxygen steelmaking converter. The model includes sub-models for lime dissolution and heat loss calculation. FactSage™ software and its macro programming facility were employed to integrate thermochemical and kinetic information into the model. The model predicts the temperature, composition, and volume of several phases involved in the process. The model predictions transient metal and slag compositions and metal bath temperature, were found to be consistent with the plant data.
碱性氧气炼钢过程中冲击区和乳化区的精炼——一项基础研究
对联合吹(顶吹和底吹)氧气炼钢过程中发生的动力学的深入了解,特别是在单独反应器内的冲击区和乳状区,可以为炼钢中的精炼机制提供更深入的理解。已经建立了一个动态模型,可以预测各种精炼过程的贡献,如脱碳、脱硅、脱氮和脱磷。该模型考虑了氧炼钢转炉冲击区气-金属相互作用和乳化液区渣-金属-气体相互作用。该模型包括石灰溶解和热损失计算的子模型。采用FactSage™软件及其宏编程工具将热化学和动力学信息集成到模型中。该模型预测了该过程中涉及的几个阶段的温度、组成和体积。该模型预测了瞬态金属和炉渣成分以及金属浴温度,与工厂数据一致。
