METHOD FOR CONTROLLING NOSE CAMBER IN HOT ROLLING

Japanese Patent JP3251455

B2

PURPOSE: To independently control the amount of nose camber into the target value and, even when there are a restriction from the viewpoint of the material of a rolled stock, restriction from the viewpoint of equipment, restriction from the viewpoint of operation, or the like in a finish rolling stage, to minimize the amount of nose camber at the time of completing rolling by jointly using with other camber control within the range of these restrictions. CONSTITUTION: In hot rolling in which a slab is heated in a heating furnace and a plate is manufactured by executing rough rolling and finish rolling, the amount of nose camber which is generated at the time of finish rolling is preliminarily determined based on operation data as a functional equation respectively taking difference between set temps. in upper and lower parts and residence time of the slab in the heating zone and soaking zone of the heating furnace as variables. About the rolled stock of an object, by applying the predetermined residence time of the slab in the heating furnace and target amount of nose camber to the functional equation, the respective difference between the set temps. in the upper and lower parts in the heating zone and soaking zone of the heating furnace is determined and set so that the amount of nose camber which is generated at the time of rolling becomes the target value.
