    21-01-2019· Cold rolling is a process that occurs after hot rolling in order to reduce the thickness, increase the yield and tensile strength and pliability of metal. It is a relatively expensive and labour-intensive process, but the improved mechanical properties increase the value of the finished product, whether that is a sheet, strip, or coil.

    FEATURING ROLLING AND PROCESSING Primetals

    been successfully applied many times in tandem cold mills. When rolling below a certain strip thickness, the control mode is switched from speed control to roll-gap control while the strip tension is kept constant. In this solution approach, the looper measures the strip tension between the stands and the looper position remains constant.

    Selection of Work Roll Diameter for Cold Rolling Mill*

    in a batch-operated rolling mill and of the final stand in a tandem cold mill, the strip tension is sometimes greater on the entry side than on the exit side. In such circumstances examination of the forward slip should be necessary. (3) The tendency to the higher draft diminishes the forward slip.

    A Review on Chatter Analysis in Cold Rolling process

    common process of cold rolling operation known as chatter. This happened due to numerous discrepancies occurring during manufacturing process, such as roll vibration, variation in strip tension and negative damping [1]. Chatters lead to thickness variation (across the width), surface damage and undesirable noise at work place.
