METHOD OF CLADDING TWO-LAYER BIMETAL Russian patent published in 1994 - IPC

FIELD: production of bimetallic rolled stock. SUBSTANCE: method comprises steps of preparing components and their combined rolling in a stand different circumferential speed values of rolls, turning the roll, being driven, to a component of the bimetal, having dependant friction factor, sustaining a speed difference of the rolls upon rolling for welding the components of the bimetal one with another being proportional to a mismatch of the friction factor of the bimetal components in such a way, that the proportionality coefficient is equal to (0.321-0.417) of reduction value upon the same rolling process. EFFECT: enhanced quality of clad sheets. 1 cl, 2 tbl
