Abstract

PURPOSE:To eliminate the influence of interference of cooling water from adjacent headers and to improve cooling efficiency, by inclining the direction of cooling headers, jetting cooling water, to the direction of material width at a specified angle, and arranging them at the upper stream side and down stream side alternately. CONSTITUTION:Many cooling headers 2 are arranged in the direction of the width of hot rolling material so as to cross over the material, and are inclined to the direction of sheet width at an angle theta and faced to the material. The inclined angle theta is made >=5 deg., and adjacent headers 2 are arranged to point the upper stream side and down stream one relative to the material running direction. Cooling water jetted onto the material 1 from the header 2 which are arranged alternately keeping the inclined angle theta, flows on the material 1 to the territory of adjacent header 2 and; the cooling water flow 3 with the same flow-tendency coollides with each other at the intermediate position between mutual headers 2 to create an interference flow 4. The interference flow 4, de-energized by the following cooling-water flow 3, is swept away successively to the direction of material width not to flow to the position just below the jetting one of the header 2.
