Abstract: A method for setting a roll gap of sinusoidal corrugated rolling for a metal composite plate includes steps of: determining entrance thicknesses, exit thicknesses, a width, and a rolling temperature of a difficult-to-deform metal slab and an easy-to-deform metal slab; detecting a roll speed and an entrance speed of a metal composite slab, obtaining a roll radius and friction factors; determining parameters of a sinusoidal corrugating roll and a quantity of complete sinusoidal corrugations on the sinusoidal corrugating roll; then calculating a time required for a complete corrugated rolling; calculating a rolling force at any time during the sinusoidal corrugated rolling of the metal composite plate; and calculating the roll gap S of the corrugated rolling at any time according to the rolling force F, and configuring a rolling mill to have the roll gap S according to an actual rolling schedule before normal production.

Abstract: A transverse vibration rolling system and a preparation method for a double-layer metal composite ultra-thin strip relate to a technical field of rolling, which solve problems including poor rolling and bonding effects, low geometric accuracy, and poor plate shape quality of metal composite ultra-thin strips. The transverse vibration rolling system includes: a first roll, a second roll, a first hydraulic vibrator, a second hydraulic vibrator, a first hydraulic motor, a second hydraulic motor, a check valve, a first hydraulic pump, a first overflow valve, an oil tank, a controller, a second overflow valve, a second hydraulic pump, an electromagnetic reversing valve, a first speed control valve, and a second speed control valve. The transverse vibration of the rolls of the present invention can apply transverse shearing force on the ultra-thin metal strips during the bond rolling.
