<p>In order to provide a hot rolling facility with which an improvement in the manufacturability and the quality of a thin plate material can be achieved with little facility investment, this hot rolling facility is equipped with a first rolling line (A), which directly performs finishing rolling with multiple rolling mills (12a, 12b) on a thin slab (Wa) cast with a continuous-casting machine (10), and a second rolling line (B), which, with a roughing mill (21), reversibly rolls a thick slab (Wb) heated in a batch-type heating furnace (20), with an intermediate material (Wc) that has been rolled with the second rolling line (B) being transported to the first rolling line (A) and undergoing finishing rolling at the first rolling line (A) to produce a final product (S). The multiple rolling mills (12a, 12b) respectively comprise an upstream rolling mill (12a) and a downstream rolling mill (12b), each of which is formed with at least one rolling mill stand. A crop shear device (30) that cuts and evens up the front and rear ends of the slabs (Wa, Wc) rolled with the upstream rolling mill (12a) is installed on an intermediate table between these rolling mills (12a, 12b).</p> |
