When wrapping angle of cold strip covering surface of shape detecting roll dynamically changes, online radial pressure of the shape detecting roll is changed too, and it seriously affects online shape detecting precision of cold strip. The cold strip online dynamic wrapping angle compensation model is established, and successfully applied in 1250 mm 6-high cold mill, remarkable results is achieved. The error between calculated values and measured values of total tensions is within 3%.

Comprehensive considered actual working conditions of cold rolling mill, a high precision shape detecting system of cold rolling strip was developed to meet industrial application. Consideration to both follow-up processing technology requirements, dynamic flatness standard curves could be formulated according to different rolling conditions and product specifications, and reliable shape datum were provided for close-loop shape control. This system was successfully used in Angang 1250 mm HC 6-high reversible cold rolling mill. Then the shape index and the quality stability of cold rolling strip were increased significantly, the errors between the calculated values and measured values of the total tension were less than 3%, the precision of shape detecting is 0.2 I and shape indices was within 6 I after the close-loop shape control was input.

In producing stainless steel cold rolling strip, stripe and decorative pattern shape defects occur on the surface, and influence its quality. This paper uses the spot investigation, defects microscopic analysis and scanning electron microscopy spectrometer methods in order to give a detailed analysis about surface defects, discusses the essence of defects, causes and effects process, puts forward valuable suggestions and provides reliable data for the actual production.
