摘要： The invention belongs to the technical field of metal micro-forming, and in particular relates to a method for inflating micro-channels. The present invention is aimed at the problems of low process flexibility, single product type, and non-closed structure of the micro-channel when preparing metal micro-channels by micro-plastic forming of ultra-thin metal strips. The present invention uses a method combining numerical simulation and bond rolling experiment to analyze the effect of the hydrogen pressure and bond strength of the metal composite ultra-thin strip after bond rolling on the pore diameter of the micro-channel, and the corresponding relationship between the micro-channel pore diameter and the titanium hydride content, heating temperature, and bond strength of the metal composite ultra-thin strip is obtained. The present invention has no special requirements on molds, wide selection of metal materials, low requirements for equipment capabilities; closed tubular micro-channel products with different pore diameters and different distributions can be prepared according to requirements, with rich product categories and high process flexibility.

摘要： 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.
