Abstract
An improved electric tube furnace is described in which a compressible leaf-spring attachment between the heating element tube and at least one of its supporting electric terminals compensates for linear thermal expansion of the tube without restricting access to the interior of the tube. The use of such furnace in an evacuated atmosphere for high temperature thermal diffusivity measurements is shown.
Claims7
Warp resistant high temperature electric tube furnace comprising a rigid metal heating element tube having open ends and a supporting electric terminal ring coaxially disposed and attached adjacent to each end of said tube, each said ring having an inside diameter at least as large as the inside diameter of said tube and at least one said ring being tandemly spaced from said tube and remotely, compressibly attached through a plurality of flexible elongated rectangular metal strip connectors which are symmetrically spaced about the periphery of said tube and radiate to said remotely attached ring.
