钢铁企业工序能力匹配关系思考

针对高炉→转炉→热轧→冷轧流程，分析了工序能力和物流匹配的关系，提出了炼铁工序能力＜炼钢工序能力＜热轧工序能力＞冷轧工序能力；其中铁钢比0.90～0.96，热轧和冷轧间的匹配程度为1∶（0.4～0.8）。炼钢厂内精炼能力＞冶炼能力＞连铸能力；轧钢厂内热轧能力≥加热炉能力，冷轧能力＞深加工能力。为满足流程匹配关系，需开发“铁 铸 轧一体化”的生产管理系统和冷区网络化物流管理模型。

Matching of Process Capability in Iron and Steel Enterprise

Matching relationship between process capability and mass flow was analyzed based on Blast furnace converter hot rolling cold rolling process.The results that ironmaking productivitycold rolling productivity is put out; the ratio of iron to steel is 0.9~0.96 and the matching degree of hot rolling with cold rolling process is 1：（0.4~0.8）.the matching relationship in steelmaking plant is refining capability>melting capability > continuous casting capability; the matching relationship in rolling plant is hot rolling capability ≥heating furnace capability and cold rolling capability >further processing capability. In order to meet the process match demand, it is necessary to develop integrated manufacturing management system of iron-casting-rolling and network mass flow management model in cold rolling zone.
