Abstract
A closure assembly for a furnace wall in which a plug member is secured to a shell member which, in turn, is pivotally mounted to the furnace wall. The plug member is formed from a cast ceramic fiber tamping mix of bulk fiber and high temperature inorganic binders and has a relatively low density. A centrally located stepped bore extends through the plug member for receiving a rod to the interior face of the shell member. A fastening means engages the rod for securing the plug member relative to the shell member and an insert formed from the same material as the plug member is fixed in the bore hole.
