ABSTRACT:
An inspection hole cover for coke ovens includes a bowl-shape shell made of a material having relatively low magnetic properties such as 300 Series stainless steel. The shell is filled with a suitable heat insulating material such as a hardened refractory filler or ceramic fiber. A closure member may also be provided at the open end of the shell for retaining the heat insulating material within the cover. Because the cover is relatively non-magnetic, it is not subject to inadvertent removal by magnetic lifts used in coking facilities. However, provision is made for lifting the inspection hole cover by a hook, and a method of making the cover is also disclosed.
