Application Of Induction Heating To Control Sheet Flatness In Cold Rolling Mills

US Patent:
2007019, Aug 23, 2007
Filed:
Feb 20, 2007
Appl. No.:
11/676908
Inventors:
William Beck - Bettendorf IA, US
Srinivas Garimella - Pittsburgh PA, US
Michael Globig - New Kensington PA, US
Mark Puda - Cheswick PA, US
Michael Ringle - Knoxville TN, US
Frederic Schultheis - Knoxville TN, US
Neal Vernon - Knoxville TN, US
International Classification:
B21B 37/28
US Classification:
072011700
Abstract:
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.

Sixth Order Actuator And Mill Set-Up System For Rolling Mill Profile And Flatness Control

US Patent:
6314776, Nov 13, 2001
Filed:
Oct 3, 2000
Appl. No.:
9/677622
Inventors:
Mark E. Puda - Cheswick PA
Assignee:
Alcoa Inc. - Pittsburgh PA
International Classification:
B21B 3758
US Classification:
72 101
Abstract:
A rolling mill stand having a pair of side shiftable rolls defining a roll gap profile therebetween varying along the length of the rolls according to a sixth order polynomial equation. The flatness of the strip exiting the rolling mill stand is controlled by determining the temperature profile of the rolls and adjusting the side shift positions of the rolls to compensate for the expansion of the rolls due to changes in the temperature of the rolls.
