Recalibrating mill for treating one of the last stand of a cold or hot rolling mill or from a finishing facility or the like

Rolling stock

The invention is a Hachkalibrierwalzwerk to on "and would take a treatment of the last stand of a cold or hot rolling mill or a Adjustageeinrichtung or dglο coming rolled _o

The rolling stock emerging from the rolling mill or _P dgl ₀ disadvantageously often does not yet have the necessary or desirable form and dimensional accuracy. Experience has shown that deficiencies of this type cannot be excluded or eliminated in the rolling stock with conventional rolling mills alone. ”As a result, the rolling stock is often sufficient not to for various reasons high as alternate border claims in form and surface finish and dimensional tolerances · this results in the requirement that the rolling mill or possibly another device, for "B ₀ a Adjustageeinrichtung, coming rolling nor a subsequent treatment to refine the surface and to achieve the greatest accuracy of form and dimensions »

To remedy the deficiencies and disadvantages indicated here and In order to achieve further advantages, a recalibrating mill is used according to the invention for treating the one from the last scaffold

Cold or hot rolling mill or rolling stock coming from another facility is proposed, in which all multi-roll stands have the same inscribed circle - target diameter with free expansion possibility and all multi-roll stands are provided such that they can be driven in this way continuously without tension or pressure between the roll stands by their own common main drive motor with a basic speed range od that all More rolling stands on differential located in the direction of rolling behind the first Mehrwalzengerüat transmission by means of associated individual drive motors. _o the like are regulated individually drivable "

This advantageously makes it possible to use a common main drive motor to drive all multi-roll stands with the required speed and force and also to configure the drive for each multi-roll stand located behind the first multi-roll stand individually in such a way that the rolling stock can be treated continuously or without pressure between the individual stands results »

Construction and arrangement of the rollers or discs in the scaffolds can be provided such that the rolling stock is free to wide _east

According to a further feature, the first multi-roll stand is provided so that it can be driven directly by the main drive motor or via intermediate gears Od ₀ like _e , while each subsequent multi-roll stand is also driven by the main drive motor at the corresponding base speed via a

Differential gear and associated with it a single auxiliary drive motor is regulated individually drivable "From this it is an advantage, all multi-roll stands provided only by a main drive motor to drive ₀ The present under the particular rolling conditions necessary speed deviations can be about for driving the second and third, and about further more mill stands Achieve differential gears and the individual drive motor assigned to each multi-roll stand.

An example of the invention shown in the drawing is explained below

In the Uachkalibrierwalzwerk consisting of several multi-roll stands, the first multi-roll stand 1 and the multiple-roll stands 2, 3 following in the rolling direction can be driven by their own common main drive motor od _e like 4 with a basic speed range o Here the first multi-roll stand 1 can be driven by the main drive motor 4 via interposed gears or the like «, 5,6,7 or, if necessary, directly driven in a manner not shown here drivable «The
