[origin: US6092701A] PCT No. PCT/CH97/00284 Sec. 371 Date Feb. 5, 1999 Sec. 102(e) Date Feb. 5, 1999 PCT Filed Jul. 25, 1997 PCT Pub. No. WO98/05451 PCT Pub. Date Feb. 12, 1998A refractory plate for a sliding gate valve at the outlet of a vessel containing molten metal has a polygonal external shape and has a longitudinal axis, on both sides of which at least two side surfaces, disposed at an obtuse angel ( gamma ) to one another, extend and serve as clamping surfaces of the plate in a metallic frame (11) or the like. The shorter side surfaces are arranged to extend at an angle ( alpha ) of between 20 DEG and 50 DEG to the longitudinal axis while the longer side surfaces are arranged to extend at an angle ( beta ) of between 10 DEG and 30 DEG to the longitudinal axis. The refractory plate can thus be optimally clamped and an increased service life is thus consequently achieved.
