Rolling Mills Selection Guide: Types, Features, Applications
Rolling mills are machines that shape metal by passing it through two rolls. They are used to flatten and reduce metal to a sheet or plate. Most rolling mills feature two or more rolls arranged in a symmetrical pattern, with half above the work and half below the work to be rolled. Typically, the rolls are mounted one above the other and rotate ...
Reversing cold mills for steel
