ABSTRACT:
A lightweight cover provides heat insulation for a heated metal container, e.g., a ladle. The insulation cover is assembled in a manner providing for ease of repair plus simplicity of maintenance. The assembly has a frame member with depending guide means useful for straddling engagement with the container. Frame member impact assemblies provide resilient mounting of the cover on the container. Ceramic fiber insulation is placed within the frame and abuts upwardly against a roof over the insulation. The insulation is secured to the roof. Stiffeners above the roof connect with the frame member. The entire insulation cover assembly is most particularly useful for retarding radiant and conductive heat loss from the container.
