| 摘要 |
The present invention relates to the rolling of assembled metal slabs and, more particularly, to methods for increasing slab rolling yields and rolling mill efficiency by minimizing shearing and crop losses in the rolling of assembled slabs. This invention provides an assembled structure for aluminium rolled products comprising a core slab (1) with a reduced cross-section in the thickness direction of the slab in at least one of the slab edges running parallel to the rolling direction. At least one second slab (2) is assembled to the core slab. The edges of the slab (1) may have a cut-out and/or a tapered shape. The invention also provides a method of reducing shearing and crop losses at the rolling of assembled slabs, by using a core slab (1) with a reduced cross-section in the thickness direction of the slab in at least one of the slab edges running parallel to the rolling direction.
