Abstract

PURPOSE:To efficiently manufacture a hot rolled strip with a good flatness, by successively applying a quenching, a reheating and a coiling process to a steel strip just running out of a hot finish rolling stand. CONSTITUTION:A steel strip 3 running out of a hot finish rolling stand, is introduced into a hot run spray zone 2 wherein the strip 3 is quenched by a water spray. Then, the strip 3 is introduced into a heating zone 4 wherein the strip 3 is reheated to about 200 deg.C-600 deg.C by burning heavy oil or gas; thus reheated strip 3 is then directly coiled by a coiler 5 and is naturally cooled in the air. The condition of said heat treatments is adjusted according to the property of the steel or to the kind of purposed service. By the present method, a steel strip with a good flantess, free from both of thermal stress and strain, is manufactured.
