HilfSTOrrichtung for shifting τοπ rolling stands in rolling mills

The installation costs of modern continuous fialzenstraßen are due to the required complicated electrical drive and locking devices so high that there is a it is imperative that the τοη is necessary from time to time Conversion of the road to be carried out in the shortest possible time, so with the associated loss of production can be kept as low as possible in order to achieve this goal, various paths have already been taken been. It has been proposed, for example, that the roll stands should be connected to their drive units by means of quick-release couplings.

\ ^ Spindles to be connected and displaced transversely to the rolling line to arrange on their base plates, so that the prepared reserve scaffolds can be placed by a crane in its place.

Another Vorsaal-Lg amounts to two Vorstaffeln must be provided, each of which is used for a specific ^ cross-sectional area was designed. This made it possible Each season is easier to keep in its structure, because it would otherwise be the case in an extensive rolling program required blind caliber in the rolls of the Vorstaffel come in discontinuation and on the other hand the control range of the Drive motors could be smaller. With such a design of the Waizenstraßen there is a production failure only slightly, mostly also the completion phase can be provided in a double arrangement; such Systems are from; -r, due to two preliminary stages, expensive and thus inexpedient despite the achievable advantage.

It is also known to move part of the roll stands of a rolling train so far across the Waizlinie, that on their steep guide or means of transport for the

Rolling stock can be used so that, while the extended stands are being rebuilt, with the rest of them Scaffolding can be rolled further. Such a solution is also unsatisfactory because it Can only be used on roller mills with a narrow rolling program.

To with rolling mills with an extensive rolling program, as it is required, for example, when on a road In addition to wire of various cross-sections, fine iron is also to be produced, the framework change is quick to be able to do it, it is suggested after the firing, all reserve frames at the distance required for rolling on a common support frame (wagon or Slide) to be arranged in the longitudinal direction of the rolling line is movable. The lateral distance between the support frame and the base plates of the roll stands is preferred so that the reserve scaffolding can be coupled to the existing displacement means of the scaffolding. laugh at shedding everyone the rolling stands to be converted from the rolling line to the carriage, this is moved in the longitudinal direction of the rolling line, until the reserve scaffolding is opposite the corresponding base plate for receiving the scaffolding. You will then with coupled to the displacement means and onto the whale line aligned. In the case of continuous rolling mills with several relays, it is advantageous to have one for each relay were to be assigned for the inclusion of all roll stands.

The conversion of a roller train or a relay can thus be carried out in a much shorter time than it is 'was previously possible, so that the loss of production only is very low. Another advantage is given by the fact that they can be extended laterally when using them Salt stands, the lower edge of which is below the rolling mill floor, the previously necessary pits and theirs Covering means can be omitted. In these cases, the rolling stands are lifted up to the level of the rolling mill floor by lifting rams raised and can then also on. pushed the car. In the case of rolling mills whose rolling

scaffolding cannot be moved in the longitudinal direction of its rollers are arranged on their sole plates, the necessary displacement means can be arranged on the carriage. On the basis of the drawing, which schematically shows an embodiment of the firing in FIGS. 1 to 6, are the details of which are explained in more detail below.

Should these stands because of the changeover of the rolling program against the reserve stands marked 3a to 3f are exchanged, the stands located in the rolling line are moved by a shifting device 4, in the exemplary embodiment a double-acting piston guided in the cylinder. 5, pushed onto the carriage, 6, See.
