Abstract (en)
A hot rolling apparatus having a rough rolling mill (24, 35, 36) and a finish rolling mill (28, 37) disposed downstream of the rough rolling mill (24, 35, 36) so as to successively roll a slab material (7) to reduce the thickness of the material thereby to produce a sheet product (32). The rough rolling mill (24, 35, 36) comprises a reversible rolling mill capable of performing forward and backward passes. A take-up device (65, 71) capable of coiling and uncoiling the material under rolling is provided on the upstream side of the rough rolling mill (24, 35, 36). This arrangement eliminates necessity for a huge table system which is used for supporting the long rolled material after a backward rough rolling pass immediately before the last forward rough pass, so that the size and investment cost of the apparatus can be remarkably reduced.
