ABSTRACT:
A hot top for an ingot mold has a plurality of sections mateable along adjoining edges. The sections include two diametrically opposed lift sections engageable by a crane for transporting the hot top and an intermediate section fitting between corresponding ends of the lift sections. A tongue and groove joint is provided along the adjoining edges of the sections to make them readily detachable and facilitate interchange of sections of different lengths. The joint is tapered in the longitudinal direction from top to bottom of the edges so as to transmit an upward force to the intermediate sections when the lift sections are raised thus preventing separation of the sections when the hot top is transported.
