对不锈钢侧顶复吹AOD精炼过程数学模拟作了初步研究,注意到该精炼过程的物理和化学特性,考虑体系的质量和热量衡算,以及添加渣料、切头切尾和废钢、合金料等操作,精炼过程的不等温状态、钢液和熔渣质量的变化等因素的影响,提出了一个针对整个精炼过程的数学模型.基于设计的操作模式,以该模型对120 t侧顶复吹AOD转炉内奥氏体不锈钢的整个精炼过程,包括氧化(脱碳)和还原过程作了模拟和估算,与工艺设计给出的参照数据作了比较.
The mathematical simulation of the AOD refining process of stainless steel top and bottom blowing was preliminary studied. The physical and chemical characteristics of the refining process were noticed. Considering the quality and calorific value of the system, as well as the addition of slag, cut ends and scrap, And other factors such as the operation, the non-isothermal state of the refining process, the quality of the molten steel and slag, a mathematical model for the entire refining process is proposed.Based on the designed operation mode, The entire refining process, including oxidation (decarburization) and reduction of the austenitic stainless steel in the AOD converter was simulated and estimated, and compared with the reference data given in the process design.
