<p>Provided is an apparatus for straightening a rolled steel sheet capable of precisely setting rolling reduction of a straightening roll according to an actual temperature value of steel sheet before straightening. The apparatus for straightening a rolled steel sheet comprises multiple straightening rolls which are vertically and alternately placed apart from each other along a process line of the rolled steel sheet and pressure a steel sheet; a prior temperature sensor which detects the temperature of a raw steel sheet entering the straightening rolls before straightening; and a control unit controlling the rolling reduction of straightening rolls according to a temperature value detected by the prior temperature sensor.</p> |
