Ceramic fiber insulated furnaces with electrical hanger element of great mechanical integrity

摘要

This invention relates to an electrical element support system that utilizes a series of ceramic hanger elements of generally rectangular cross-section which are adapted to be inserted into a clip which is attached by welding or bolting to the furnace wall. The clip provides bearing surfaces which match surfaces on the hanger element to provide support for the electrical element which is carried at the end of the support. The outer end of the hanger element generally has a hook or other device which is adapted to hold a particular electrical heating element.
