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.

In a hot top for an ingot mold, said hot top comprising a plurality of sections mateable along adjoining substantially vertical edges, said sections including a pair of diametrically opposed lift sections with means engageable by a crane for transporting said hot top and an intermediate section fitting between each of the corresponding ends of the lift sections, and means for connecting said lift sections and intermediate sections together, the improvement in said hot top in which:
- said connecting means comprises a tongue and groove joint extending longitudinally along the adjoining edges of said lift sections and intermediate sections so that said sections are readily detachable and may be interchanged with sections of various lengths to change the size of said hot top,
- said joints being tapered in the longitudinal direction thereof so as to transmit an upward force to the intermediate sections when the lift sections are raised and thus prevent separation of the sections during transport of the hot top.
