Recognition and Evaluation System for Strip Flatness on 2030 mm Cold Tandem Mills

In order to accomplish the quantitative evaluation of strip profile, a flatness recognition and evaluation system was proposed, which combines a pattern recognition model based on the fuzzy classification principle and a flatness evaluation model by multi-grade statistics. This system was tested by the data measured from 2030 mm cold tandem mills and a good stage-by-stage result was achieved.
