doi:10.3901/JME.2016.04.054

Abstract

Abstract: In order to adapt the requirement of strip shape measuring in high speed cold rolling and realize the nationalization of strip shape testing and manufacturing technique, a new high-speed inner close piezoelectric shape measuring roll is self-developed for cold rolled steel strip, and it has been applied to a 4-tandem cold mill consisted of 6-high 900UCM stands. A complete set of calibration and analysis platform of the shape meter is independently developed. And a series of tests are carried out on the whole machine. The influence factors and its calibration and compensation scheme of the flatness detection signal are comprehensively researched, such as the rotation speed of the roll, the wrapping angle and the flexural deflection of measuring roll, the superimposed stress caused by uneven coiling of steel strip and the partial load of the strip edge. The problems such as electromagnetic interference of piezoelectric signal, electromechanical decoupling of shape signal, transmission of infrared wireless signal and inner closed of circuit have been solved. The continuous trouble-free operation in industry field has proved that it has the reasonable structure and stable performance. Moreover, the detection signal can accurately reflect the strip shape of the scene, and the detection precision can meet the requirements of the industrial field. The research provides good detection conditions for the high speed close-loop control of cold rolled steel strip.

Key words: contact, high speed, piezoelectric shape measuring roll, strip, tandem cold rolling
