Heat conductor support disk

摘要

A multi-apertured ceramic disk heat conductor support for use in a heating element for electrically heating industrial furnace installations. The ceramic disk has a center aperture extending between exterior surfaces on an axis of symmetry for receiving a supporting element. Further apertures extend are provided for receiving heat conductors. The further apertures are equidistantly disposed around at least one circle which is coaxial with the center aperture. The further apertures have a respective axial portion, and a respective widening portion at least at one end thereof which increases in diameter from the axial portion toward a respective exterior surface of the ceramic disk. A rounded transition region between the axial portion and the widening portion is provided and the length of the axial portion is less than one-half the thickness of the ceramic disk.
