摘　　要：光整机是连续热镀锌机组的重要设备。酒钢热镀锌机组投产后,生产薄规格产品(h≤0.5mm)时往往由于光整机处带钢划伤而降级。本文通过对光整机处惰辊的受力分析,得出了影响惰辊打滑的因素有带钢张力Q、带钢对辊身的摩擦系数f和轴承对辊颈的摩擦系数μ,并结合原因给出了解决划伤的对策。通过提前调整避免了因为光整机处带钢划伤引起产品质量降级现象的发生。Skin Pass Mill （SPM） is an important equipment of the continuous hot dip galvanizing line. In JISCO CGL production, the thin strip （h ≤0.5mm）are demoted often caused by the scratches o Through the stress analysis about the idle roll the article concluded that the factors affectint the idle roll slippage are strip tension （Q）,the friction coefficient of the strip and idle roll （f）,the friction coefficient of the bearing and the roll neck （μ）, and puts forward the measures to solve the problem of scratches, and as a result, the adjustment in advance can avoid the demotion caused by strip scratches of SPM.
