Re-turning plant for rollers of a rolling mill

A re-turning plant (1) for rollers (7) of rolling mills of a type comprising at least one roller stand (1) and a plurality of rollers (7) connected to the roller stand (1) through supporting organs (6) movable in the plane of the roller stand (1), said rollers (7) being positioned within the roller stand (1) in a work position in which work surfaces (9) of the rollers (7) determine the outer profile of a body to be rolled, wherein the re-turning plant (1) comprises:

• a support structure (12) suitable to support the roller to be re-turned;
• a tool-holding device (13) that can be displaced relative to the roller-support structure (13) such as to be capable of placing the tool (37) in contact with said work surface (9) of the roller (7) in order to carry out the working on the latter;
• mandrel means (14) that can be coupled to the roller (7) and suitable to pivoting the latter, wherein
• said support structure (12) is configured to support the whole roller-stand (1) in a turning position,
• said tool-holding device (13) can be displaced in contact with the work surfaces (9) of each roller (7) of the plurality of rollers (7) fixed in the roller-holding stand (1), substantially in the work position, when the whole roller stand (1) is supported by the support structure (12) in said turning position,
• said mandrel means (14) comprise means (15, 16) that can be rotatably coupled to each roller (7) of the plurality of rollers (7) fixed to the roller stand (1), in order to rotate the roll substantially in the work position when the whole roller stand (1) is supported by the support structure (12) in said turning position,
• said re-turning plant (1) further comprising adjusting means (26, 27) configured to interact with said supporting organs (6) for adjustably varying said work position of the rollers (7) in the roller stand (1).
