Abstract

A descaling abrading apparatus with abrading rolls comprises an apparatus frame, a bearing member, and a plurality of parallel abrading rolls supported horizontally by the bearing member. Each abrading roll includes a rotating shaft, disk-shaped abrading wheels successively mounted on the rotating shaft via their corresponding collars, and spring supporters each concurrently serving as a key and disposed between their corresponding abrading wheel and their corresponding rotating shaft. The abrading wheels of one abrading roll are each located facing the collar between two corresponding adjacent abrading wheels of another adjacent abrading roll. The bearing member is supported by the apparatus frame so that it may be vertically movable with respect to the apparatus frame and so that it may be vertically downwardly pressurizable by a pressurizing means.
