Abstract

The invention relates to a process for producing three-layer rolled products by rolling composite ingots. The ingots are produced by casting bars according to the continuous casting process and guiding them, when issuing from the mould, along a curved path at first downwardly and then upwardly until a height at which the liquid core of the bar cannot ascend any further so that when casting and transportation is continued a hollow bar is obtained said hollow bar then is cut into pieces which are permitted to solidify and then are poured full with a metal of a composition different from the composition of the bar. This process permits a simple and low-cost production of sheets clad with layers which, compared to the overall thickness of the sheets, are very thin.
