Summary: | The invention belongs to the technical field of cladding plate rolling, and in particular relates to a cladding plate rolling device and a cladding plate rolling method for achieving gradient tissue regulation and control. The device comprises a liner plate and a slab. The slab is placed above the liner plate, two symmetrical grooves are formed in the liner plate, and the grooves are formed by three tangential arcs. The method comprises the following steps of heating the slab in a heating furnace to a preset temperature and keeping the temperature, pre-heating a roller to 200 DEG C, and then inputting the slab to a rolling machine for first pass normal horizontal rolling; putting the slab on the liner plate after rotating the slab at 90 degrees clockwise, keeping the temperature of the slab and the liner plate together at the preset temperature for a same time, and then carrying out second pass rolling on the slab and the liner plate; and S3, removing the liner plate, and rotating therolled slab at 90 degrees |
