Method and production line for manufacturing metal strips made of copper or copper alloys

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.

1 . A production line for producing metal strip from copper or copper alloy with at least a melting installation, a casting installation, and a rolling installation, preferably for cold forming from 23 mm to 0.2 mm copper strip thickness, wherein the melting installation is followed in succession in the direction of production by at least one vertical continuous strip casting installation and/or one horizontal continuous strip casting installation, a milling installation immediately downstream, a strip uncoiler, a cold rolling installation, a strip coiler, and an annealing installation. 
     
     
         2 . The production line in accordance with  claim 1 , wherein the cold rolling installation consists of a reversing mill. 
     
     
         3 . The production line in accordance with  claim 2 , wherein the milling installation is located immediately downstream of the vertical continuous strip casting installation. 
     
     
         4 . The production line in accordance with  claim 1 , wherein the vertical continuous strip casting installation, the milling installation, and the reversing mill follow one another in immediate succession. 
     
     
         5 . The production line in accordance with  claim 1 , wherein the cold rolling installation consists of a tandem mill. 
     
     
         6 . The production line in accordance with  claim 1 , wherein the vertical continuous strip casting installation, the milling installation and the tandem mill follow one another in immediate succession. 
     
     
         7 . The production line in accordance with  claim 1 , wherein two parallel upstream vertical continuous strip casting installations and milling installations are assigned to the tandem mill. 
     
     
         8 . The production line in accordance with  claim 1 , wherein one vertical and one horizontal continuous strip casting installation, each with a milling installation installed immediately downstream of it, are installed upstream of the tandem mill. 
     
     
         9 . The production line in accordance with  claim 1 , wherein with two parallel-casting vertical continuous strip casting installations, a reversing mill follows each milling installation. 
     
     
         10 . The production line in accordance with  claim 1 , wherein parallel-producing vertical and horizontal continuous strip casting installations are each followed by a reversing mill. 
     
     
         11 . The production line in accordance with  claim 1 , wherein the annealing installation consists either of a box annealing installation for coils or of a continuous annealing installation in the form of a strip floating furnace.
