ABSTRACT:
A furnace for heating work material comprises an outer wall defining a space therein. A first upright cylindrical shell is disposed within the space and defines a work chamber for receiving work material to be heated. A second upright cylindrical shell surrounds and is spaced outwardly of the first shell to form a heater space therebetween. A heater assembly comprises support pins disposed across and supported atop the first and second shells. A generally vertically extending electrical heating element is supported from the support means, is disposed within the heating space, and extends around at least a portion of the periphery of the first shell. The heating element is unconstrained against free thermal expansion and contraction in vertical directions relative to the first and second shells.
