Abstract

The object of the invention is to improve the quality of cast hot strips. The object is achieved in terms of the method by a method for producing hot metallic strips, in particular of lightweight structural steel, wherein a melt is charged in the presence of inert gas by means of a runner onto a circulating casting belt of a horizontal strip casting facility, solidifies to form a pre-strip with a thickness of between 6 and 20 mm and, after thorough solidification, the pre-strip undergoes a hot rolling process. The invention is characterized in that the heat transfer and the contact (surface area, time) between the strand solidified to form a pre-strip and the casting belt is reduced, and by a device for carrying out the method.
