Abstract

PURPOSE: To automatically freely control the thickness of rolled material, by memorizing thickness deviation on the feed side corresponding to the longitudinal position of rolled material, being actually measured at the one pass former rolling pass, and by controlling the gap of rolling rolls depending on above thickness deviation, at rolling the taper steel plate.
CONSTITUTION: At rolling the steel material 10 by the rolling mill 12 to manufacture the taper plate, the feed-forward system automatic thickness controller, constituted of the roll gap detector 14, the roll gap driver 16, the roll gap controller 18, the traveling distance measuring device 24 for rolled steel material 10, and the controller 28 internally provided with the device 26 for memorizing the feed side thickness deviation measured at one pass former rolling pass correspondingly to the longitudinal position of the rolled material 10, is additionally provided with the external setter 30 for setting the false feed side thickness deviation corresponding to the longitudinal position of the rolled material 10, being capable of giving the required longitudinal thickness change. This false feed side thickness deviation is overlapped on the feed side thickness deviation memorized in the memory device 26 of the controller 28, and the specified taper shape can be obtained.
