FIELD: manufacture of sheets of aluminum and low-strength aluminum alloys with thickened cladding of high-strength aluminum alloys.
SUBSTANCE: method comprises steps of separately heating before assembling pack, ingots of aluminum or low-strength aluminum alloys and aluminum-clad plane plates; heating ingots till temperature consisting 0.45 - 0.56 of melting temperature of aluminum and heating aluminum-clad plane plates till temperature consisting 0.72 - 0.76 of said temperature; rolling assembled two-layer or three-layer packs according of multi-pass schedule at deformation rate (0.02 - 0.4) 1/s and at reduction degree 5 - 10% during first three passes. The whole process is realized in industrial mills for hot rolling.
EFFECT: enlarged assortment of clad materials on base of aluminum or low-strength aluminum alloys having thickened cladding of high-strength aluminum alloys produced with use of hot rolling of packs.
