  • Metal plateness controlling method and device
    Patent number: 6615633
    Abstract: The present invention provides a method to control the flatness of a metal sheet or plate by effectively preventing waviness from occurring at the edge portions of the sheet or plate when it is cooled to the room temperature after completing hot rolling, and an apparatus to carry out the method: and relates to a method to control the flatness of a metal sheet or plate by homogenizing the surface temperature distribution of the metal sheet or plate through; measuring the surface temperatures of the metal sheet or plate at the edge portions and the center portion across its width between two rolling stands of a tandem finishing mill, or at the entry to and/or the exit from a reversing finishing mill, or after completing hot rolling, or after hot leveling; controlling the heating temperatures of the edge portions and/or the center portion based on the measured surface temperatures; and then cooling the metal sheet or plate after completing the finishing rolling.
