ABSTRACT:
A lightweight, refractory soaking pit cover is formed from a plurality of trapezoidally shaped modules, with adjacent modules positioned wide-face-up and wide-face-down, and contained within a periphery of higher density rim blocks. The rim blocks and wide-face-down modules are attached to a structural steel frame, while the wide-face-up modules rest by gravity on the edges of the rim blocks and wide-face-down modules. The modules are readily replaceable and provide a lightweight construction and good insulation properties.
