Embodiment Construction

[0028] exist figure 1 shows schematically the lower roll 1 (in this particular view the lower support roll) of a four-high rolling mill stand 2 not shown in detail, which is located in the installation position between the two stands Inside the pillars 3a, 3b and laterally next to the roll stand at the roll change location. The lower roll 1 is mounted rotatably with its front journals in the roll support 4 and is guided height-adjustably on vertical guides in the support windows of the stand supports 3a, 3b. The rolls are fed in and out of the rolling stand by means of a roll changing device 5 on which the rolls are supported by means of roll chocks 4 . The displacement process takes place by means of a pressure medium cylinder 6 articulatedly coupled to the roll changing device.

[0029] as from Figures 2 to 4As can be seen in the details of , the stepless alignment of the rolls (work rolls or backup rolls and work rolls together) to the rolling line is achieved by means ...

Abstract

The invention relates to a roll changing device with a steplessly operating wedge adjusting device. To achieve a particularly small overall size, which is specifically suitable for the conversion of existing rolling stands, it is proposed that the adjusting wedge (8) has a continuously planar wedge surface area (12a, 12b), that the wedge adjusting device (7) comprises a clamping device (16) for fixing the adjusting wedge (8) and that the upper pressure plate (19) in the roll changing device (5) is vertically and horizontally guided.

Description

technical field [0001] The invention relates to a device for changing the height of rolls in a rolling stand and for carrying out roll changes. This is done by means of wedge setting devices for aligning the lower work rolls on the rolling line, the wedge setting devices comprising wedges displaceable in the longitudinal direction of the rolls with continuously flat wedge faces; A push mechanism connected to the adjusting wedge as well as a clamping mechanism for fixing the adjusting wedge and for changing the rolls by means of a roll changing device movable in the longitudinal direction of the rolls, wherein the rolls are supported end-on-side in the roll chocks , and is guided in a height-adjustable manner in the parallel set of frame pillars, each of the two roll chocks is supported in the frame pillars by an upper pressure plate, an adjustment wedge and a lower pressure plate. Background technique [0002] It is known to align the upper edge of the lower work roll on th...
