转炉炉料配比最优参数的分析与求解
|
摘要
以转炉炼钢为研究背景,利用元素平衡和热平衡进行必要分析,结合炉料价格函数实现炉料配比模型的构建。提出使用两种不同的算法进行配比参数的求解,通过与生产数据进行比较,实现了生产成本降低、效益提升的目标。同时,对两种算法进行了比较分析,得出梯度投影法更加优越。经验证,该理论对于指导实际生产也具有着非常积极的意义。
The furnace charge proportion mode is established combining with the furnace charge's cost function by using the element balance and heat balance for analysis,all above mentioned are based on steel- making by converter as the research background. At the same time,two different algorithms are proposed to solve the proportional parameters,which are compared with the production data,so that the production cost reduction and efficiency increase targets are realized. Two algorithms are compared and analyzed in the meantime,it reaching a conclusion that gradient projection method is better. It is proved this theory has very positive meaning to guide the actual production.
