Abstract

PURPOSE:To make it possible to perform remarkable width screw-down of the slab, by installing several vertical mills and one or more horizontal mills, which have caliber rolls at the delivery of the continuous casting equipment, and carrying out press rolling. CONSTITUTION:The upper roll 6 and the lower roll 7 of the horizontal mill 3 are shunted to the positions U2 and U4. In case a continuous casting slab is fed in the direction X and is simultaneously rolled with the caliber rolls 4, 5 of the vertical mills 1, 2, the slab is made to cause compressive stress in order to prevent causing a crack, by making speed of the roll 4 slightly faster than that of the roll 5, and also arranging so that press rolling can be made. When the rear end of the slab passes through the roll 5 of the lower reach, the slab is made to reverse in the direction of Y. After the aforesaid forward and reverse pass has been carried out by odd number times, the rectangular section is molded by setting the upper roll 6 and the lower roll 7 of the horizontal mill 3 of the last pass to the respective positions U1 and U3, and melting down the dog-bone which has been produced at both sides of the slab width.
