Abstract
An improved process for continuously casting a strand of steel comprising the bending of the steel with at least one corrugated roll. The strand is preferably pushed between a corrugated roll and a smooth roll by gravity or drive rolls to impact only compressive stresses to the strand. A curved strand cast with a curved mold can be straightened between two corrugated rolls having different surface corrugations to impart compressive stresses.
