ABSTRACT:
A crucible for an induction heating apparatus has a base pan and a collar between which lies a refractory lining. Respective lower and upper mounting rings secured to the base pan and the collar are vertically interconnected by an annular array of non-round-section tierods that are tubular so a coolant can be passed through them. These tierods further have angularly juxtaposed sides which define spaces of outwardly decreasing angular width. Wedge-shaped blocks of refractory and electrically insulating material tightly fit between the sides of the rods and are of outwardly decreasing angular width. Inside these blocks the crucible is lined with further layers of refractory material.
