轧制钢

In order to find the regularity and mechanism of vibration of CSP mill during rolling thin container strip,torsional vibration of main drive,vertical vibration of stand and suppression measures of three intermediate stands were tested in spot.Then the relationship between strip chatter marks and technological parameters,and vibration of rolling mill,and necessary conditions for chatter mark generation were researched.

广州珠江钢铁有限责任公司引进的6机架CSP热连轧生产线，在轧制薄规格钢板时出现了严重的振动问题，此时带钢和轧辊表面出现明暗相间的振纹，它加快了轧辊的磨损，影响了带钢的质量，增加了后边机架矫正表面的工作量。
