Embodiment Construction

[0037]To produce a metal strip 1 from a soft material (FIG. 1), molten metal 2, e.g., copper or a copper alloy, is cast from a melting furnace (not shown in detail) in a continuous strip casting process, and the copper strip 4 is descaled by milling 5 with support rollers arranged obliquely opposite each other on the upper side 5a and the underside 5b of the copper strip 4, subjected to a cold rolling process 6, subjected to a surface inspection 12, coiled into a coil 13, and then prepared for shipment.

[0038]A coil 13 can also be returned to the cold rolling process 6 for further reduction of the thickness 18 of the copper strip. The microstructure, which is thus very strongly compressed, is coiled into an inspected coil in a treatment by annealing 7, pickling 8, washing 9, drying 10 and possibly a temper rolling step 11, followed by an inspection 12.

[0039]Stacked sheets 14 are then produced from the coils 13, whose surfaces have been inspected, by cutting the copper strip 4 to leng...

Abstract

A production line for manufacturing metal strips made of copper or copper alloys by means of casting and rolling. In order to lower the investment cost and operating expenses therefore, the melt is cast into a copper strip in a vertical and/or horizontal continuous strip casting process, and the hot copper strip is cleaned by milling the top and bottom face thereof, is subjected to a cold rolling process, and is prepared for shipping, or is subjected to an inspection and then prepared for shipping after being annealed, pickled, washed, dried, and optionally temper rolled.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application is a Divisional Application of U.S. patent application Ser. No. 11 / 988,328, filed Jul. 18, 2008, which is a 371 of International application PCT / EP2006 / 006590, filed Jul. 6, 2006, which claims priority of DE 10 2005 031 805.3, filed Jul. 7, 2005, the priority of these applications is hereby claimed and these applications are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]The invention concerns a method and a production line for producing metal strip from copper or copper alloys by casting and rolling.[0003]Until now, metal strip of this type made of soft metals, such as copper or copper alloys, has been produced by casting in slabs (DE 692 22 504 T2). After it has been cooled, the slab must be reheated and rolled out to the required thickness in a hot rolling process. The hot rolling is followed by milling of the upper and lower surfaces, inspection, and coiling into a coil. The metal strip is un...
