The method relates to a method for casting steels on arcuate continuous casting installations, a steel melt being passed through a water-cooled chill mold from which a steel product emerges which has solidified at the surface and is cooled by the action of coolants for the further solidification, deflected circularly over supporting rollers, and subsequently bent from the arc by means of multi-point bending equipment back into the horizontal. The force for straightening the arc-shaped steel product is calculated from the high-temperature properties of the steel determined from high-temperature tensile tests and from the temperature profiles of the steel product calculated from surface temperatures. By a theoretical-actual comparison of values of the calculated straightening force and the actually determined straightening force, the casting conditions and the cooling are controlled so that the steel product is treated as gently as possible during the straightening, whereby surface fissures can be largely excluded.
