Abrégé
(EN)
The invention discloses a roller replacing device and a method used for rapidly replacing a working roller and based on the roller replacing device. The roller replacing device and the method are suitable for a cluster mill. The working roller of the cluster mill is not provided with a bearing pedestal, or the working roller is provided with the bearing pedestal, while assembly parts of the working roller and the bearing pedestal have a transverse movement space which is not less than the assembly width of the working roller in a rack in the transverse movement direction of a rolled product under a roller replacing state, and the movement space allows another set of working rollers to coexist in the rack with the working roller before the working roller is pulled out of the rack; the roller replacing device is provided with at least two rows of clamping heads, one row of clamping heads corresponds to the inlet side of the rolled product to be named as inlet clamping heads, and the other row of clamping heads is close to the outlet side of the rolled product to be named as outlet clamping heads; and each row of clamping heads comprises the pair of upper and lower clamping heads, and the clamping heads are mutually and parallelly suspended. According to the roller replacing device and the method, through cooperation of the roller replacing device and a working roller bracket, the roller replacing device enters and comes out of the rack of the cluster mill at a time, then replacing of the working roller can be completed, and the roller replacing efficiency is obviously improved.
