Abstract: The present invention relates to the technical field of fabricating a metal composite strip, and specifically relates to a method for differential temperature rolling of composite strips based on actions of a friction roller and a device thereof. A method for differential temperature rolling of composite strips based on actions of a friction roller comprises steps of: S1: preparing a metal strip to be bonded, and performing surface treatment on the metal strip to be bonded; S2: frictionally heating the metal strip to be bonded by several sets of friction roller heating devices; measuring a surface temperature of the friction-heated metal strip to be bonded strip by a temperature detector; according to a measured temperature, adjusting a rotation speed of the friction roller in the friction roller heating devices; and S3: transporting the heated metal strip to be bonded to a rolling mill for rolling to obtain a metal composite strip. The invention adopts the friction roller heating devices in rolling process of the metal strip to be bonded, utilizes the friction heat generation effect of the high-speed rotating friction roller and the metal strip to be bonded, and generates different heat in the dissimilar metals by adjusting the speed of the friction roller, thereby generating different temperature rise to realize different temperature rolling of the metal composite strips.
