Abstract
A method for differential temperature rolling of composite strips based on actions of a friction roller includes 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.
