Basics of Rolling and Rolling Mills IspatGuru

May 30, 2013· Fig 4 Roll configurations in rolling mills. Two-high mill roll configuration This is the most commonly used rolling mill configuration. In this configuration, there are two horizontally mounted rolls. The rolling mill motor drives either both rolls (top and bottom) or only one roll (normally the bottom roll) with the top roll rotating due to the friction between the roll and the work piece.

Drive selection for rolling mills Russula

May 20, 2010· But in a rolling mill, normally any drive that fails will shut the mill down until it is repaired or a “work-around” is found. Normally larger common bus drive systems as used rolling mills require 2 or 3 such rectifier modules in parallel. Adding an additional rectifier module to provide redundant capacity is easily done, which alleviates
