Abstract

An invention is directed to a method and an installation for producing a hot-rolled steel strip from continuously cast primary material in consecutive work steps, wherein the primary material is brought to hot rolling temperature after solidification and is inserted into a rolling mill for rolling out into a finished strip, wherein the primary material is coiled after reaching the hot rolling temperature, is stored intermediately in a rotary hearth furnace, and is recalled, as needed, uncoiled and rolled out to form a finished strip, the intermediate storage being effected immediately prior to entering the finishing train, the coils being preferably stored intermediately in a horizontal position and with a horizontal coiling axis, a subsequent heating being effectable during the intermediate storage.
