Abstract
A metallurgical vessel having a crucible supported by a trunnion having opposing axially aligned pins on which the vessel can rotate. At least one pin has a self-holding inward taper and fits in a tapered hole in the trunnion with an interference fit. The tapered pin can be inserted in the hole and be removed much easier than a cylindrical pin in a mating hole.
