Abstract

PURPOSE:To uniformly and efficiently cool an aluminum-made extruded material in the peripheral direction by shifting a nozzle for cooling the aluminum-made extruded material in the peripheral direction of the extruded material while directing the direction to the outer peripheral surface of the extruded material. CONSTITUTION:Since the extruded material E is cooled by injecting cooling medium, i.e., mist while reciprocatively shifting the nozzles 3... to the periphery of the extruded material E in the peripheral direction, the extruded material E can uniformly be cooled to this peripheral direction, and can be the extruded material is quenched without bending and warping. Further, the number of the nozzles arranged in the peripheral direction can be reduced by the peripheral directional shifting type nozzle constitution, and the spouting water pressure in each nozzle 3... can be made to be high and the extruded material E can efficiently be cooled. Further, since the nozzles 3... are shifted to the periphery of the extruded material E in the peripheral direction, this cooling device can be cooled in the peripheral direction without hindrance to the high temp. extruded material E extruded from an extrusion machine.
