Abstract

PURPOSE: To considerably reduce the quantities of bends of the wide flange beams by beforehand force cooling both side flange parts under the specific conditions at the time of feeding the slabs of the specified length having been hot rolled in H-form posture to a cooling device.
CONSTITUTION: The wide flange beams having been hot rolled and cut to the specified length are run in an H-form posture on a line table 6, and cooling water is sprayed from nozzles 3, 3 of headers 5, 5 opposedly disposed on both sides of the table. The respective slabs 1 having been force cooled are parallel disposed in the cooling chamber in the I-form posture having rotated 90°, but spacings between the adjoining slabs, temperature differences between the respective slabs and the differences in cutting length give influence to each other and therefore the rates of cooling of the right and left flange parts differ, producing bends in the lengthwise direction. Hence, the quantities of the bends are beforehand estimated through calculation or actual measurement and the rate of flow of the cooling water, the positions of its spraying to the flange parts and the rotating speed of table rollers 8 are so adjusted as to offset the quantities of the bends.
