摘　　要：为降低转炉合金成本,采用线性规划为核心算法,开发了转炉合金模型。模型通过设计碳冗余质量分数和磷冗余质量分数、确定合金收得率和LF增碳质量分数等主要参数、基于优先加足低价合金的原则分配转炉合金用量,在满足钢水成分的前提下降低了合金成本,可产生经济效益3.27元/t。In order to reduce converter alloy cost,the converter alloy model was developed using linear programming as the core algorithm.The model through designing carbon redundancy and phosphorus redundancy,determining main parameter such as alloy yield and carbon increment of LF treating process and allocating alloy amount of converter based on preferentially using lower price alloy.The cost of alloy was reduced under the premise of meeting with qualified component of liquid steel,and the economic benefits was 3.27 yuan/t.
