摘　　要：济钢三炼钢随着大板坯连铸机产能不断提高,扇形段所承受的负荷不断增加,三节辊辊间距超差、轴承损坏情况严重。通过采用CARB轴承,轴承座冷却水槽改进,改进二冷喷淋系统,调整辊间距对中参数等措施,有效提高扇形段三节辊寿命,平均使用寿命由不到30万吨提高到90万吨。As a result of Slab CCM forNo.3 Steel-making Plant of JIGANG＇group Co, Ltd constantly upgraded the efficiency, load of CCM segments constantly increased, three-section rollers ＇out-of-tolerance and bearing damage incerased.threugh some solutions,which included using CARB bearing,changing the structure of bearing block cooling flumes,improving second cooling system,adjusting the roller＇s gap parameter, improved notably the segment rollers＇ service lives.the average segment rollers＇ service lives improve from 300,000 ton to 900,000 ton.
