HOT ROLLING PRACTICE – An Attempted Recollection

The layout of a rolling mill varies, from a simple single stand mill to several stands positioned either side by side or in a line. A mechanism, commonly called a roller table, directs the work piece to the rolls, and another roller table for handling the pieces emerging out of the roll. The table in front of the rolls forces the steel
