Abstract
PURPOSE:To make the temperature distribution uniform along the longitude of a material to be rolled by a nonferrous metal hot rolling mill, by arranging a heater for heating the tip of the material on the feed-in side of the rolling mill in order to prevent the temperature drops caused in the top and bottom ends of the material to be rolled. CONSTITUTION:The said material's tip heater 9 is constituted of a material heater 10 for heating the material 6 to be rolled, a material heating controller 11 for controlling this heater 10, and an operational command generator 13 for generating such control commands 12 to be given to the controller 1 as a heating start timing, a heating time duration, and a heating rate. The heater 10 and controller 11 are divided into n-zones in the same direction as the longitude of the material 6 to be rolled, so that the working condition of optional any zone can be determined according to the control command 12. In the present constitution, if the heater 9 is controlled, any temperature drop along the longitude of the material 6 to be rolled, especially in the tip and bottom ends, can be prevented, so that the quality of the final product is improved as compared with the conventional product quality.
