Abstract Refractory Plate and Method for Reinforcing A refractory member adapted for use in a casting vessel valve is disclosed including a refractory plate, a wire helically wound around the periphery of the plate, and means rigidly interconnecting the helical windings to one another. A method is also disclosed for reinforcing a valve plate, including the steps of heat- ing a metal wire into a malleable state, securing one end of the wire with respect to the plate, helically winding the heated wire about the plate with the wind- ings substantially abutting one another, and welding together each wire winding with the abutting windings at at least one spot. An apparatus for performing the method is also disclosed, including means for rotatably supporting the plate with its periphery exposed, drive means for rotating the supported plate, means for orienting a reinforcing wire in a position generally tangent to the supported plate, and means for heating the wire to a malleable state before winding about the plate.
