Method and apparatus for steering strip material through rolling mills
Abstract
Abstract DESCRIBED ARE A METHOD AND APPARATUS FOR STEERING STRIP MATERIAL THROUGH A ROLLING MILL, PARTICULARLY WHEN THE MILL IS BEING THREADED, IN A MANNER TO PREVENT THE STRIP FROM TURNING OFF THE CENTER LINE OF THE MILL DUE TO CAMBER (I.E., ONE EDGE OF THE STRIP BEING THICKER THAN THE OTHER). THIS IS ACCOMPLISHED BY ADJUSTING THE SPACING BETWEEN THE ROLLS AT THEIR OPPOSITE ENDS SO AS TO EQUALIZE THE ROLL FORCES ON OPPOSITE EDGES OF THE STRIP AS IT IS THREADED THROUGH THE ROLLS. AFTER THE STRIP IS, THREADED THROUGH THE ROLLS AND TENSION APPLIED THERETO, EITHER BY A SUCCEEDING ROLL STAND OR BY A COILER, THE ROLLS CAN BE ADJUSTED TO MAINTAIN THE SPACING BETWEN THEIR OPPOSITE EDGE THE SAME OR NEARLY THE SAME. THE INVENTION ALSO ENCOMPASSES STRIP STEERING FOR THE PURPOSES AS WELL AS STRIP STEERING COMBINATION WITH STRIP SHAPING AND GAGE CONTROL.
