Embodiment Construction

[0034] exist figure 1 A strip mill 1 is schematically illustrated in FIG. 2 with a multi-roll rolling installation 2 having a press nip 3 through which a metal strip 4 is guided. The metal belt can be guided through the press nip 3 in alternating directions, wherein the press nip 3 is narrowed before each changeover. In this way, a reduction in the thickness of the metal strip 4 is achieved. The metal strip 4 is a high-grade steel strip in this embodiment.

[0035] To cool the metal strip 4 , oil is applied by means of an application device (not shown) before the pressing gap 3 . A press 5 a , 5 b of identical design is arranged on both sides of the press nip 3 for oil removal. The presses 5a, 5b have upper press rolls 6a, 6b and lower press rolls 7a, 7b, between which a press nip 8a, 8b is formed between which the metal strip 4 is guided pass through it. A winding station (not shown) is arranged in each case on the side of the presses 5a, 5b facing away from the press ni...

Abstract

The invention relates to a squeezing unit (5) for a strip rolling mill and to a strip rolling mill comprising such a squeezing unit, wherein the squeezing unit (5) has an upper roller (6) and a lower roller (7), between which a squeezing nip (8) is formed. To achieve long service lives, ensure low residual moisture and minimize surface damage on the strip, at least one of the rollers (6, 7) is provided with a revolving shell (9) and a stationary yoke (10), which passes axially through the shell (9), wherein a pressing device (12) is arranged between the yoke (10) and the shell (9). The pressing device (12) subjects the shell (9) to an outward bearing pressure in a radial direction, wherein the bearing pressure is variable over a roller width such that zonal control and active width adjustment are effected.

Description

technical field [0001] The invention relates to a strip mill for the cold rolling of metal strips, especially special steel strips, said strip mill having a multi-roll rolling installation and a press with upper and lower press rolls , forming a press nip for guiding the metal strip between said upper and lower press rolls, wherein at least one of the press rolls has a surrounding sheath and a fixed yoke passing axially through said sheath part, wherein between the yoke and the sheath a pressing device is arranged which exerts a pressing force on the sheath outwards in a radial direction. Background technique [0002] During the cold rolling of metal strips, in particular special steel strips, the thickness of the metal strip is reduced by applying pressure to the metal strip, for example between two coiling stations of a multi-roll rolling plant. Such a multi-roll rolling installation is known, for example, from EP 0693328 A1. [0003] Here the metal strip is unwound from...
