Abstract
A refractory sliding gate valve plate has a planar upper surface and a planar lower surface parallel to the planar upper surface. A connecting outer surface connects the upper surface to the lower surface, and a pouring channel fluidly connects the upper surface to the lower surface. Specified ratios of length between (a) specified longitudinal segments extending from the axis of symmetry of the pouring channel to the perimeter on the upper surface and the lower surface of the plate, respectively, and also between (b) specified latitudinal segments extending from the axis of symmetry of the pouring channel to the perimeter on the upper surface and the lower surface of the plate, respectively, increase the uniformity of thrust force applied to the plates and the contact area between the upper surfaces of two such plates within a valve.
