Abstract
Heat treatment equipment for metal plate strips, and a roller quenching flow zone control device for metal plate strips. The device includes a middle water diversion ring sleeve and edge water diversion ring sleeves; the middle water diversion ring sleeve is installed at the middle processing groove in a slit nozzle rear spiral roller and a high-density nozzle rear spiral roller in a high-pressure cooling section of a roller quenching machine; and the edge water diversion ring sleeves are installed at the processing grooves in ¼ and ¾ positions in the width direction of the slit nozzle rear spiral roller in the high-pressure cooling section of the roller quenching machine. This can effectively realize uniform distribution of cooling water on the surface of the plate strip, reduce the phenomenon of local non-uniform cooling caused by siltation of cooling water.
