A method and apparatus for straightening castings formed in a continuous-casting operation. After a partially solidified casting emerges from a continuous-casting mold, it travels through bending rolls and a curved roll rack which change its direction of travel from vertical to horizontal, but the casting acquires a curved set and must thereafter be straightened. The straightening apparatus of the present invention includes lower and upper series of rolls closely confining a casting, yet avoiding excessive forces such as would damage the casting, which may still have a liquid core. The apparatus has a critical combination of driven and idler rolls of varying diameters, which afford the necessary mechanical strength at reaction points, yet maintain minimum spacing between rolls in each series and allow standardization of the drives for the driven rolls.
