Abstract

The invention relates to the field of rolling production and can be used in ferrous and non-ferrous metallurgy, mainly in the production of thin tape. The purpose of the invention is to increase the rigidity of the roll set and increase the productivity of the cage. Supplying the roll set with additional support rolls 5, 6 allows for a more efficient arrangement of the rolls in the set. Each pair of work rolls 1, 2, or 3, 4 is used by turning the cassette in a particular rolling direction. Work rolls with this arrangement are not subject to either vertical or horizontal bending. Productivity is increased by reducing transhipments. 1 hp ff, 4 ill. CO Figure 1

Description

The invention relates to rolling production and can be used in ferrous and non-ferrous metallurgy, mainly in the production of thin tape.

The aim of the invention is to increase the rigidity of the roll set and increase the productivity of the stand.

FIG. 1 shows a diagram of a roller assembly when rolling a strip from left to right; in fig. 2 - the same, for example about the pro: at: ke strip from right to left; in fig. 3 - cassette; in fig. 4 - set of rolls, production version.

The set of rolls (Fig. 1) contains js workers 1-4 and supporting 5-8 rollers. When rolling, for example, from left to right (Fig. 1), strip 9 is deformed between work rolls 1 and 2. In this case, rolls 3 and 4 contribute to an increase in the stiffness of the knot rolls in the longitudinal direction, and supporting rolls 5 and 7 increase the stiffness of the roll knot in the vertical direction. To change the direction of rolling, the work rolls 1 and 2 are diluted, and the additional rolls are reduced at the same direction of their 25 rotation. In this case, the strip 9 begins to deform between the rolls 3 and 4 (Fig. 2}. In this case, the main part of the horizontal force acting from the strip on the rolls 3 and 4 is perceived by the shaft 20

The use of the proposed roll set will allow to increase the productivity of both divisions of the multi-roll working stand, and the continuous mill, which includes multi-roll stands, by reducing the number of rolls by almost half, and also increase the rigidity of the set of rolls due to its more rational layout and installation of an additional support roll.

Claims (2)

1. A multi-roll stand roll set mainly for rolling a thin belt, comprising two drive support rolls and four work rolls mounted two in rotary cassettes relative to the support rolls, characterized in that, in order to increase the rigidity of the roll set and increase the productivity of the stand, it is provided two additional support rolls, each of which interacts with the corresponding support roll, and the work rolls are installed with mutual contact and, in addition to Kami 1 and 2, and the main part of the vertical 30 addition, each work roll, respectively effort - rolls 6 and 8. Work rolls on one side are enclosed in a cassette 10 (Fig. 3). To change the direction of rolling, it is enough to rotate the cassettes located on opposite sides of the plane of the strip, around their axes. FIG. 4 shows an embodiment of the manufacture of a set of rolls in which the working and supporting rolls are made in the same cassette I. The cassette is mounted on the axis 12, which rests on the frame 13. At this pressure it interacts with only one meter support, and the axis of rotation of the cassette lies in the vertical plane passing through the contact line of the work rolls. 2. A set of rolls according to claim 1, characterized in that supporting rolls are installed in the respective rotary cassettes together with the workers, and each cassette is equipped with two push mechanisms arranged on both sides of the axis of rotation. 75 7J, T FIG. 2 The projection acting on the work roll is converted into a torque, which tends to turn the cassette 1 around the axis 12. The pressing devices 14 and 15, which have an element with ball bearings, prevent the cassette from rotating. The use of the proposed roll set will allow to increase the productivity of both divisions of the multi-roll working stand, and the continuous mill, which includes multi-roll stands, by reducing the number of rolls by almost half, and also increase the rigidity of the set of rolls due to its more rational layout and installation of an additional support roll. Invention Formula 1.
