Abstract

Asymmetric flatness occurred on the products of a 2250mm hot rolling line when they were rolled in a cold mill. The production data reflected that these products deviated much in hot rolling. Because of the large thickness, rolled pieces show asymmetric profile instead of asymmetric flatness under asymmetric rolling condition. An index is established to express the asymmetric character of profile efficiently. The tilt variables of rollers are introduced to deflection model of rollers based on influence function method to build an asymmetric deflection model to analyze the influence of deviation on the asymmetric index of rolled piece profile when pieces of different width and height are rolled as well as at different stands. This is of great importance for controlling deviation of rolled piece to ensure its shape quality.
