Abrégé
(EN)
A roller replacing apparatus (1) suitable for a cluster mill. Under a roller replacing state, assembly parts of a working roller and a bearing pedestal have a transverse movement space which is not less than the assembly width of the working roller in a rack in a transverse movement direction of a rolled product, 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 apparatus is provided with at least two rows of clamping heads, one row of clamping heads corresponds to an inlet side of the rolled product to be named as inlet clamping heads (3), and the other row of clamping heads is close to an outlet side of the rolled product to be named as outlet clamping heads (2); each row of clamping heads comprises a pair of upper and lower clamping heads, and the clamping heads are suspended parallel to each other. Also disclosed is a method for rapidly replacing the working roller based on the roller replacing apparatus. By means of cooperation of the roller replacing apparatus and a working roller bracket, the roller replacing apparatus completes replacing of the working roller by entering and coming out of the rack of the cluster mill at a time, so that the roller replacing efficiency is improved.
