为区分连续生产线上带钢板面划伤缺陷的来源，判断辊子速度偏差对板面质量的影响，进而解决这种产品缺陷，本文提出了一种新分析方法。通过介绍带钢板面划伤缺陷产生的机理，着重指出了造成辊子速度偏差的因素，将样本标准差理论运用到偏差的分析中，明确了造成划伤的速度偏差值，最后介绍了解决速度偏差的排查方法和经验。该分析方法在生产中得到推广运用，实现了准确识别缺陷来源、快速解决速度偏差的目的。

For the discrimination of strip scratch which is caused by roll touch in continuous line , and the estimation of speed deviation wheather can make a influence on strip surface , this paper provides a new analysis method .It introduces the process of strip scratch that appears in the roll touch .Especially ,it shows the factors which will result in speed deviation .Al-so,it proposes the use of sample standard deviation method in the analysis , and the value which can lead to scratch .Finally, it provides the solution of speed deviation and share the experience in analysis with readers .When this method is widely used in the process of strip scratch analysis ,we can exactly discriminate the factors of scratch ,and resolve the speed deviation quickly .
