The roughing mill is one of the most loaded parts of the steel plant; it consists of two reversing 3-high mill stands with ten passes, eight in first stand and two in second, Fig. 1. The failures of the rolls with grooves on the 1.stand of the 3-high-roughing mill stand occurred four times, Refs. [1], [6].
They represent an innovation solution for roughing and intermediate mills and constitute the latest stage of 3-high stand evolution. Features: A fixed rolling line with sliding stands to match the exact groove according to pass design reduced roller table width.
