Abstract

The straightness of rolled steel is improved by controlled cooling with water under pressure which, depending on the composition of the steel, accelerates or retards the .gamma./.alpha.-conversion and prevents the rolling stock, while on the cooling bed, from being warped or increased in length by the conversion.
