Cold Mill an overview ScienceDirect Topics
John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014. 7.17 Reduction of Local Buckles. Even though the cold mill itself may cause local buckles, the majority of the local buckles are caused by the feed stock from the hot mill (Melfo et al., 2006). Therefore, proper monitoring of the hot band profile and mechanical properties will be the first choice to reduce local buckles.
