Basic Examination on Strip Wandering in Processing Plants
In strip processing plants, strip passing through long distance at high speed is particularly important to produce high quality products. If the strip wanders in the line because of strip shape, thermal effect or other factors, stable plant operation is disturbed.<br>This report is concerned with strip lateral wandering.<br>The cause of strip wandering is clarified by using a model processing plant. Strip camber and welded joint angle, that is a non-straight form of the strip, mainly gives rise to wandering. The effects of misalignment on the equipment are small.<br>Tension leveler that corrects not only shape defects but also camber and welded joint angle is very effective to depress wandering.<br>Pinch roll to prevent strip wandering, the hearth roll and the quenching roll to prevent a thermal crown have been newly developed to hold good strip tracking.
