Sheet and plate metalwork 281 The '' condition '' of the material being bent will infl uence the amount of spring back likely to occur. For example, an aluminium alloy that has been coldrolled to the halfhard condition will exhibit greater springback than the same alloy in the fully annealed condition for the same degree of bending. Compensating for springback
A special roll stand is used to direct the strip from each coil to the mill. This roll stand indexes to the next lower coil each time a coil is depleted. In most operations, enough coil can be preassembled to satisfy the requirement for one shift, so mill operation is continuous for at least one shift.

Continuous casting, also called strand casting, is the process whereby molten metal is solidified into a "semifinished" billet, bloom, or slab for subsequent rolling in the finishing mills. Prior to the introduction of continuous casting in the 1950s, steel was poured into stationary molds to form ingots. Since then, "continuous casting" has ...
The secret to developing successful roll tooling—whether for tube production or roll forming—and achieving maximum roll integrity is a simple but often overlooked notion: a comprehensive approach.
Roller mills are also more sensitive to instantaneous changes in the feed rate than are other pieces of process equipment. Feeding a roller mill directly from a screw conveyor or bucket elevator will cause surges in the feed rate that the roller mill "sees" instantaneously unless some damping system such as a surge hopper is used.
