摘　　要：针对棒材Ф550粗轧机组轧辊发生的辊颈断裂事故,分析出产生原因为球墨铸铁轧辊辊颈强度不足。通过选用半钢轧辊、重新优化设计其配辊,校核与计算Ф550半钢轧辊辊颈强度,能够满足生产需求,避免了轧辊辊颈断裂的事故,保证了生产的稳定顺行。The cause for the accident of roll neck rupture at roll of Ф550 bar roughing mill was analyzed as the deficiency of the strength of ductile cast iron roll neck.The production demand was met through selecting semisteel roll,re-optimizing design and roll arrangement and calculating and checking the strength of Ф550 semisteel roll neck.The reoccurrence of the same rupture was avoided and stable and smooth production ensured.

关 键 词：轧辊 辊颈 强度 材质 安全系数
