摘要
转炉炼钢是一个多变量耦合的复杂工业过程,为了提高转炉炼钢过程中碳和温度测试的命中率,提出一种在静态模型基础上加入反应速率权值的计算模型。模型根据铁水中各元素的氧化物分解压和浓度,制定了不同吹炼时期各元素反应权值作为氧气分配的系数,并根据热平衡与物料平衡原理,计算铁水实时碳含量与温度。仿真结果表明,在碳含量允许误差为0.15%、温度允许误差为12°C的条件下,模型的碳含量命中率为94.68%,温度命中率为92.77%,碳温双命中率为88.7%,对实际生产有一定的指导作用。
Converter steelmaking is a complex process with multi-variable coupling.In order to improve the hit rate of the carbon and temperature test in the process of converter steelmaking,a calculation model with reaction rate weight is proposed based on the static model.The different reaction weights of each element in different blowing periods are formulated as the coefficient of oxygen distribution according to the decompression and concentration of the oxide of molten iron,and the real-time carbon content and temperature of molten iron are calculated according to the principle of thermal balance and material balance.The simulation results show that the carbon content hit rate is 94.68%,the temperature hit rate is 92.77%,and the rate of carbon and temperature both hitting is 88.7%under the condition that the carbon content allowable error is 0.15%and the temperature allowable error is 12 degrees Celsius,which has a certain guiding role for practical production.
