Abstract

PURPOSE:To eliminate fish tails irrespective of the sizes and rolling reductions of rolling materials by cooling the lateral surfaces of the metal rolling material in rolling the same. CONSTITUTION:When the rolling material 4 drawn out from a soaking pit is conveyed on a conveying table 1, a valve 6 is opened and a pump 7 is driven to radiate the cold water of a tank 8 to the lateral surfaces of the rolling material 4 through spray nozzles 5. As a result, the lateral surfaces of the rolling material 4 are cooled and become lower in temperature than the central part. The water having cooled the rolling material 4 is collected below the table 1 and returns to the tank 8. The rolling material 4 having been cooled of its lateral surfaces is rolled by rolling mills 2, 3 but the lateral surfaces are lower in temperature than the contral part and therefore the elongation of the lateral surfaces is restrained and the production of fish tails is prevented.
