5 Claims

1. A roller quenching flow zone control device for metal plate strips, wherein a metal plate strip enters a slit nozzle, a slit nozzle rear spiral roller, a high-density nozzle and a high-density nozzle rear spiral roller in a high-pressure cooling section of a roller quenching machine in sequence; the control device comprises a middle water diversion ring sleeve and edge water diversion ring sleeves; the middle water diversion ring sleeve is installed at a middle processing groove in the slit nozzle rear spiral roller and the high-density nozzle rear spiral roller in the high-pressure cooling section of the roller quenching machine; and the edge water diversion ring sleeves are installed at edge processing grooves in ¼ and ¾ positions in a width direction of the slit nozzle rear spiral roller in the high-pressure cooling section of the roller quenching machine;

wherein the middle water diversion ring sleeve comprises an upper left semicircular water diversion ring sleeve, a lower left semicircular water diversion ring sleeve, an upper right semicircular water diversion ring sleeve and a lower right semicircular water diversion ring sleeve, and inner diameters of the four semicircular water diversion ring sleeves are equal to an outer diameter of the middle processing groove; outer diameters of the four semicircular water diversion ring sleeves are equal and smaller than an outer diameter of the spiral roller in the high-pressure cooling section of the roller quenching machine by 5 mm-10 mm, spiral drainage grooves are designed in outer surfaces of the semicircular water diversion ring sleeves, a rotation direction of the spiral drainage grooves in the outer surfaces of the upper left semicircular water diversion ring sleeve and a rotation direction of the spiral drainage grooves in the outer surfaces of the lower left semicircular water diversion ring sleeve are equal to a rotation direction of the drainage groove in a left connected spiral roller, and a rotation direction of the spiral drainage grooves in the outer surfaces of the upper right semicircular water diversion ring sleeve and a rotation direction of the spiral drainage grooves in the outer surfaces of the lower right semicircular water diversion ring sleeve are equal to a rotation of the drainage groove in a right connected spiral roller; and the four semicircular water diversion ring sleeves are tightly connected and fixed according to distribution positions to form the entire middle water diversion ring sleeve;

each edge water diversion ring sleeve comprises an upper semicircular water diversion ring sleeve and a lower semicircular water diversion ring sleeve, and inner diameters of two semicircular water diversion ring sleeves are equal to outer diameters of the edge processing grooves and outer diameters of the two semicircular water diversion ring sleeves are equal and smaller than the outer diameter of the spiral roller in the high-pressure cooling section of the roller quenching machine by 5 mm-10 mm, spiral drainage grooves are designed in the outer surfaces of the semicircular water diversion ring sleeves, and a rotation direction of the spiral drainage grooves in the outer surfaces of each edge water diversion ring sleeve is equal to a rotation of the drainage groove of the spiral roller connected therewith.
