高速钢轧辊在带钢热连轧机上服役机架的最优匹配

针对带钢热连轧机生产中存在的轧辊磨损过大、易剥落、板形控制能力差等问题,结合高速钢轧辊的优缺点及实际上机服役情况,通过数值模拟分析了高速钢轧辊处于F1~F4不同机架服役时,热连轧机的板形调控能力。计算结果表明:当F4机架使用高速钢轧辊时,轧机的板形控制能力相对较强;而当F3机架为高速钢轧辊时,轧机的板形控制效果相对较好,上机试验验证了数值模拟结果的正确性,从而为高速钢轧辊在热连轧机上的应用提供理论依据。

精轧主传动交交变频同步电动机设计

０概况 攀钢１４５０热连轧于１９９３年投产,随着操作水平和管理水平的提高,轧机的生产能力已达到了１００万ｔ板材的年产量。但由于该套连轧机利用了较多的库存设备,主传动采用机组供电的直流电动机,不但能耗高、控制性能差、设备故障率高,更因电机的出力不足而直接影响产品质量和品种的扩大,难以满足市场的需求。１９９８年初攀钢决定对１４５０热连轧传动系统进行改造。 此次技术改造涉及的范围是Ｒ２机架两台主传动电机,Ｆ１～Ｆ６机架６台主传动电机及其供电、控制系统的全部设备。从满足工艺要求,提高连轧机的性能、降低能耗…
