摘　　要：用于中厚板轧机和热连轧轧机的高铬、高镍铬复合铸铁轧辊在使用中相继发生断辊事故 ,断辊事故的原因是由于轧辊过热所致 ,提出防止断辊事故的具体对策和改进措施。Fracture of the high-Cr and high Ni-Cr complex work rolls in the plate mill and continuous hot rolling mill frequently occur in the operation.Analysis shows that the primary cause to the roll failure is the over heat of the roll and therefore some counter measures have been put foreword to prevent against the trouble of roll fracture.
