Embodiment Construction

[0023] according to figure 1 The apparatus for producing aluminum strip with a textured surface comprises a cold rolling mill 17 having two work rolls 18, 20 forming a nip 19 and two backup rolls 22, 24 supporting the work rolls. The work rolls 18, 20 and backup rolls 22, 24 are mounted in a mill stand 26 in a known manner.

[0024] Also mounted in stand 26 is an anilox stand 28 which is smaller than cold rolling mill 17 .

[0025] As shown in FIGS. 2 and 3 , the anilox roll stand 28 has two anilox rolls 38 , 40 which define a nip 39 and are supported by a pair of intermediate rolls 42 , 44 . Each pair of intermediate rolls 42,44 is supported by three sets of five backup rolls 46,48 each. The back-up rolls 46, 48 are mounted on beams 50, 52 which extend over the entire roll width. The upper beam 50 is supported by means of hydraulic pistons 58 by the upper part 54 of the roll stand, and the lower beam 52 rests directly on the lower part 56 of the roll stand. The two parts ...

Abstract

A method of producing aluminum strip or aluminum alloy strip with a textured surface, wherein after emerging from a cold rolling mill (17), the cold rolled strip (12) passes through two anilox rolls ( 38, 40) and is wound so that the relief pattern is transferred to the surface of the strip due to the force of the anilox roll on the strip (12). A plant for the production of aluminum strip or aluminum alloy strip with anilox surface, in which an anilox roll stand (28) with anilox rolls is arranged directly downstream of (x) rolls in a cold rolling mill (17 ) behind. Applying this device and method it is possible to dispense with a separate anilox rolling pass, thus saving one rolling pass compared to the methods of the prior art.

Description

technical field [0001] The invention relates to a method for producing aluminum or aluminum alloy strips with an anilox surface, wherein a cold-rolled strip passes through the nip of two anilox rolls having a concave-convex pattern due to the action of the anilox rolls The force on the strip turns to the surface of the strip. The invention also relates to an apparatus for producing cold-rolled strip of aluminum or aluminum alloys with a textured surface using a cold rolling mill. Background technique [0002] In the automotive industry, aluminum alloy strips and sheets are used in the manufacture of body parts, where aluminum alloy sheets are formed by deep drawing or stretching. Lubricants must be applied during deep drawing or other forming steps. By precoating the strip or sheet in the rolling mill, not only is the forming process simplified, but it is also optimally protected during transport. [0003] In a process commonly used today, the strip producer coats cold-ro...
