Maintenance for productivity Rolling models
*) A Sendzimir mill is a mill with small diameter work rolls, each backed up by two rolls of larger diameter which are in turn jointly backed up by a cluster of three rolls. This mill configu-ration is often used for height-strength- and stainless steel. Factbox 1 ABB and rolling mills Footnote 1) A pass is one deformation step consisting of the

Analysis of roll stack deflection in a hot strip mill - SciELO
Predictive models are required to provide the bending set point for bending for the flatness control devices at rolling stands of finishing mill of Hot Strip Mill (HSM). A simple model for roll stack deflection at the finishing mill has been illustrated where a modified Misaka's equation has been used to obtain mean flow-stress.

These oscillations support the control of the mould level by the steel flow into the mould. This new process reduces the variations in the steel flow, thereby stabilizing the strand casting process. Process even stabilizes at high casting speeds. The bulging effect of a strand is greater at high casting speeds, and higher frequencies occur.

What is Cold Rolling? (with picture)
Cold rolling can be used to change the gauge of steel sheet metal. Cold rolling is a process used in manufacturing and finishing environments to change the thickness, or gauge, of metals or glass. Used mostly in steel mills, cold rolling involves threading flattened steel into a machine that advances the material through a set of rolls.
