    摘要: A system for rolling metal sheet having a substantially uniform flatness including a rolling mill including a pair of work rollers for reducing the thickness of a metal sheet, an induction heating apparatus in close proximity to at least one roller, bending jacks corresponding to each of the rollers, and a cooling spray system in proximity to rollers; a flatness measuring device positioned to measure a differential in flatness of the metal sheet; and an mill control interface connected between the flatness measuring device and the rolling mill's actuators, in which the mill control interface is configured to actuate the induction heating apparatus, the bending jacks and the cooling spray system to substantially eliminate flatness differentials is the metal sheet's flatness. The induction coil heating apparatus is configured to eliminate high tension on the strip edges caused by the temperature gradients in the work rolls at the edges of the metal strip.
