Abstract
An improved insulation is provided for furnace members, particularly verticals, cross supports and skid pipes in slab reheating furnaces. The insulation includes a metal spring-clip having outward projections on which refractory tiles are formed. An intermediate layer is provided between the outer surface of the clip and the tiles so as to reduce friction and prevent cohesion between the clip and tiles. Thus, when the clip is spread for installation on the pipes, the tiles will not break.
