THE PRESENT INVENTION DISCLOSES A METHOD FOR THE MANUFACTURE OF PRESS MANUFACTURED, BRAZED COMPOSITE SLABS FOR USE IN HOT ROLLING COMPRISING THE STEPS OF: (1) DETERMINING THE MATERIALS AND DIMENSIONS OF THE SUBSTRATE AND CLAD PLATES, BASED ON THE SPECIFICATION OF THE END PRODUCTS; (2) CLEANSING THE SURFACES OF TILE SUBSTRATE AND CLAD PLATES THAT ARE TO BE CLAD TOGETHER; (3) COMPOSING SLAB COMPRISING THE SEQUENCE OF: STACKING TWO PIECES OF METAL CLAD PLATES IN BETWEEN TWO PIECES OF METAL SUBSTRATE PLATES; PLACING BRAZING MATERIALS BETWEEN METAL SUBSTRATE PLATES AND METAL CLAD PLATES; PLACING ANTI-ADHESION AGENT BETWEEN TWO CLAD PLATES TO PREVENT FUSION OF THE CLAD PLATES AT HIGH TEMPERATURES; WELDING, UNDER PRESSURES, SEAL PLATES ONTO THE PERIPHERY EDGES OFTHE TWO METAL SUBSTRATE PLATES SO AS TO COMPLETELY SEAL OFF THE CLAD PLATES; (4) DRILLING A HOLE AND VACUUMING; (5) HEATING VACUUMED COMPOSITE SLAB TO A TEMPERATURE ABOVE THE MELTING POINT OF THE BRAZING MATERIALS, PRESSING THE COMPOSITE SLAB TO SHAPE AT THE SAID TEMPERATURE WITH A PRESS AND ALLOWING THE COMPOSITE SLAB TO COOL OFF. THE METHOD OF THE PRESENT INVENTION POSSESSES THE ADVANTAGES OF LOW PRODUCTION COSTS, SHORT CYCLE TIME,HIGH EFFICIENCY AND LOW WASTAGE. THE METHOD CAN BE WIDELY APPLIED FOR THE MANUFACTURE OF VARIOUS TYPES OF METAL COMPOSITE SLABS
