Most Conventional & Popular Mill for Rolling up to 0.2mm Output Thickness from
Input strip thickness of 1.6 to 1.8mm (Provided all other features of Emulsion
parameters and Roll Force along with Rolls are within acceptable limits. With
increase in Emulsion Performance and Roll Chemistry, even thinner Strip Gauge
at output is possible.

Basic setting facility for strip gauge control is an electro–mechanical screw down
or, in modernized plants, a hydraulic roll positioning system. In the case of
conventional four–high mills, work roll bending providing a way setting to influence
strip shape and flatness within limits is considered an improvement on the rigid roll contour, in conjunction with an on – line flatness measuring, a partial automation
is possible.
