Development and application of a measured flatness value processing method

A processing method for the measured flatness signal of a segmented contact stressometer,as well as the processing flow,was introduced in this paper.It was unnecessary to calculate the wrap angle,when the method was employed to process the measured value.The method was programmed and applied in the on-line flatness control system of a reverse cold mill as a module.Stable production and good rolled strip flatness were obtained after the mill came into service;the average flatness deviation of rolled strip was below 5 I.It was proved that the method was stable,effective and competent for on-line industrial application.
