Embodiment Construction

[0080] combine now Figure 4 to Figure 8a -8b Hereinafter, rolling mills according to several exemplary embodiments are described.

[0081] The examples described herein relate to a twenty roll Sendzimir type rolling mill as previously described and illustrated in FIG. 1 . Of course, those skilled in the art will understand that the present invention may also be applicable to other types of multi-roll mills.

[0082] Thus, in the example described here, the rolling mill 100 according to the invention comprises a rolling mill stand 10 in which the lower subgroups G I and upper group G S , including work roll 12, two first intermediate rolls 13, three second intermediate rolls 14 and 15, and four backup rolls or backup drums, the backup rolls or backup drums are arranged on the outside, and the upper group G S Represented by A, B, C, D, subgroup G I Use E, F, G, H to represent.

[0083] In the examples described here, the rolling mill 100 according to the invention is equip...

Abstract

A rolling mill (100) includes: —a rolling-mill cage (10) containing a plurality of cylinders, including two working cylinders (12) and two pairs of intermediate cylinders (13), —a main gate (30) on the front face of the rolling mill (100) for accessing all the cylinders, —a device (20) for the lateral movement of the intermediate cylinders (13) of the push-push type including first and second pairs of hydraulic actuators (22, 22′, 21, 21′) each configured so as to exert a thrust force (P) to allow a lateral movement of the intermediate cylinders (13), —a removable small gate (40) fixed to the main gate (30), allowing access to the cylinders (12) and (13), and integrating the second pair of hydraulic actuators (21, 21′) so that opening and closing the small gate (40) does not interfere with the opening and closing of the main gate (30).

Description

technical field [0001] The invention relates to the field of rolling mills, especially cold rolling mills. Background technique [0002] Thus, one beneficial use of the present invention is in multi-roll mills, typically Sendzimir mills. [0003] Cold rolling is to obtain the final thickness of the metal strip by passing the metal strip continuously between multiple rolls, where there is a large force between the multiple rolls, with both pressure and traction. [0004] A Sendzimir type rolling mill comprises multiple rolls or drums arranged relative to each other in order to modify the mechanical properties of the metal strip so as to obtain a strip thickness which may be less than 3 mm. [0005] In particular, it is known that a Sendzimir rolling mill may comprise twenty rolls; exemplary embodiments of such a rolling mill comprising twenty rolls are explained in documents US 5 193 377 and US 5471 859 . [0006] The accompanying drawing 1 accompanying the description of t...
