Abstract

A method and apparatus for heat treating steel plates subject to longitudinal length distortion wherein the plate at a temperature of the critical temperature of the steel passes through leveling rolls to remove the length distortion and immediately thereafter through quenching rolls which maintain length uniformity during quenching of the plate.
