Method for producing metal strips by continuous casting and rolling

Abstract

A method relates to producing metal strips by casting rolling. A slab (3) is first cast in a casting machine (2). The slab (3) is cleaned in a cleaning device (4) placed after the casting machine (2) in the conveying direction. The slab (3) then undergoes a heat treatment in a heat treatment device (11). Between the cleaning device (4) and the heat treatment device (11), the slab (3) undergoes a smoothing process by means of two interacting smoothing rolls (13, 14). In order to reduce energy and production costs and to improve the surface of the slabs prior to the first forming process, the smoothing process is carried out such that the slab (3) does not undergo a substantial reduction in thickness, and the roughness depth of the smoothed surface of the slab (3) is reduced.
