Abstract
A discharge assembly for controlling the discharge of molten metal from a vessel includes a stator member mounted to extend through the vessel and a rotor member coupled to the stator member to be rotatable relative thereto. A lateral opening in the rotor member is brought into and out of alignment with a lateral opening in the stator member, thereby opening communication to a longitudinal discharge passage through the stator member. One of the members has a projection fitting into a recess in the other member, with complementary sliding sealing surfaces therebetween. The projection comprises an insert formed separately from the respectively member and fixed thereto to be non-rotatable relative thereto.
