The present invention relates to a slide gate which controls a flow rate of molten steel, and more specifically, the present invention relates to a slide gate in which one pair of overlapped opposite upper and lower valve plates vary an area of a molten steel flow opening for controlling a flow rate of the molten steel. The slide gate includes an upper housing 110 having an upper valve plate 101 placed in an inner side, a lower housing 120 under the upper housing 110 having a lower valve plate 102 placed in an inner side, one pair of elastic hinge members 130 passed through a right side and a left side of the upper housing 110 or the lower housing 120 vertically to secure the lower housing or the upper housing to the upper housing or the lower housing opposite thereto such that the lower housing or the upper housing is movable up and down elastically and to secure the lower housing 120 to be enable to be opened or closed, a slider 140 in the lower housing 120 for receiving moving force from a driving cylinder C in a state the slider 140 supports the lower valve plate 102 to slide in front/rear directions, a guide track 150 mounted on an underside of the slider 140 along a moving direction of the slider 140 having recesses 151 on one side, and one pair of rollers 160 mounted on left/right sides of the lower housing 120 to make rolling contact with the guide track 150. |
