Abstract
In a metal strip rolling mill having a strip shape measuring means connected to adjust the mill to control the strip shape, improved strip shape control performance is achieved by mounting a hold-down roll between the measuring means and the take-up reel.
Claims5
In a metallic strip rolling apparatus comprising a rolling mill, a tension take-up reel to receive strip rolled through said mill and strip shape sensing means mounted between said mill and said take-up reel and constructed and arranged to adjust said mill for automatic correction of the shape of said strip being rolled in said mill, the improvement comprising a roll mounted to press against said strip between said shape sensing means and said take-up reel, said shape sensing means and said roll being in contact with opposite faces of said strip, and means responsive to the amount of said strip on said take-up reel for controlling the vertical position of said roll relative to said shape sensing means.
In a method of controlling the shape of a metallic strip as its thickness is reduced in a rolling mill wherein the shape of said strip is sensed at a sensing position by contact with said strip as said strip passes to a take-up reel, the improvement comprising contacting a roll against said strip between said sensing position and said take-up reel, said sensing contact and said roll contact being on opposite faces of said strip, and responding to the amount of said strip on said take-up reel by controlling the vertical position of said roll relative to said sensing position.
