目前国内炼钢厂普遍存在多钢种生产的复杂组织模式,生产组织中“炉”与“机”之间的匹配程度在很大程度上影响着炼钢厂生产的顺利进行.在以往研究的基础上,以国内某特殊钢厂为例,对炉机匹配问题进行分析讨论.提岀当量周期的概念,结合产品结构对炉机匹配模式进行解析;提出炉机匹配度的建议评价指标,对炉机匹配关系进行评价. At present, the complicated organization mode of multi-type steel production is common in domestic steel mills. The matching degree between “furnace” and “machine” in the production organization largely influences the smooth progress of steelmaking production. Based on the previous research, this paper takes a special steel mill in China as an example to analyze and discuss the matching problem of furnace machine.It also introduces the concept of equivalence cycle and the product structure to analyze the matching pattern of the furnace machine. Evaluation indicators, matching the relationship between the furnace evaluation.
