摘　　要：针对唐钢新区多个高炉以两种铁水罐供应多炼钢厂的场景,铁水供应和需求节奏波动大,人工分铁存在铁水供应和铁水需求信息获取不全面,容易造成分铁结果不合理的问题,提出了以铁水供需平衡为目标的智能分铁技术。智能分铁考虑在途铁量、高炉出铁计划、炼钢厂冶炼作业计划以及连铸浇次计划,精准计算铁水供需节奏,基于层流化运行准则和现场运行规则,进行自动合理分铁,并根据现场实绩变化进行动态调整。通过在唐钢新区的实际应用中进行验证,该技术对铁水重罐运行时间、在线铁水罐个数等指标有显著改善作用,满足现场使用需求。In response to the scenario where multiple blast furnaces in Tanggang New Area supply multiple steel mills with two types of iron ladles,the rhythm of molten iron supply and demand fluctu-ates greatly,and manual iron separation has the problem of incomplete information acquisition of mol-ten iron supply and demand,which can easily lead to unreasonable iron separation results.An intelli-gent iron separation technology with the goal of balancing molten iron supply and demand was pro-posed.Intelligent iron separation considers the amount of iron in transit,blast furnace tapping plan,steelmaking plant smelting operation plan,and continuous casting schedule,accurately calculates the supply and demand rhythm of molten iron,based on laminar flow operation criteria and on-site opera-tion rules,automatically and reasonably separates iron,and dynamically adjusts it according to chan-ges in on-site performance.Through practical application in Tanggang New Area,it has been verified that this technology has a significant improvement effect on indicators such as the running time of heavy molten iron ladle and the number of online iron ladles,meeting the needs of on-site use.
