ABSTRACT:
A combined, continuously operating high-speed light-section and wire mill composed predominantly of so-called cantilever stands or CL stands with overhung-mounted collars. In the roughing train and in the intermediate train and/or in the finishing train, some rolling mill stands with a modular unti with double-mounted collars are arranged. A CL modular unit of the CL stands with overhung-mounted collars can be exchanged as required against a modular unit with double-mounted collars. The second bearing of the modular unit is arranged in a box stirrup which can be coupled to the gear box of the CL stand. The collar can be assembled and disassembled with an automatically actuated, preferably hydraulically acting quick fixing device which includes piston-cylinder units for clamping and releasing the collar on the shaft in axial and in radial direction. The modular unit is a roll box of sandwich construction with box plates which can be separated from each other.
