Abstract

A shutoff and/or control assembly for use in regulating the discharge from a metallurgical vessel includes a refractory ceramic rotor member to be coupled to a stator to be rotated relative thereto to control discharge. A drive rod has an inner end extending into the rotor member and engaging therewith such that rotation of the drive rod causes rotation of the rotor member. At least an inner end portion of the drive rod is formed of a ceramic material.
