(english) The process of rubbing, grinding, or wearing away by friction.
(english) The full name for z-mill is Sendzimir mill. A Z-mill operates with a very small diameter work roll, normally about 2 inches, backed up by a number of rolls in a pyramid-shaped stack. This roll set up allows you to exert extremely high forces through the work roll and yet keep the work roll from extreme flexing. The take-up roll on the Z-Mill also exerts a tension on the coil as it comes through the mill. The combination of high pressure and tension makes the mill capable of rolling material thin and flat.
(Automatic Gauge Control) Hydraulic or electric system that supplies the force to the A.G.C. roll force cylinders.
(english) A mark transferred to the strip surface from a defective process roll. Similar to dent or punchmark.
(Environmental Engineering) The recovery and reuse of a product which would otherwise be thrown away.

(Concrete Engineering) A process in which thin flakes of matrix or mortar are broken away from concrete surface; caused by adherence of surface mortar-to forms as forms are removed, or to trowel or float in portland cement plaster.
