Abstract
A lightweight ladle cover employing ceramic fiber mats in modules. The modules are formed by having the generally rectilinear mat folded into five adjacent sections, the first of which depends vertically toward the "hot" side of the cover but is sandwiched between the second, third and fourth sections which form a vertical, horizontal ("hot" side) and vertical U-shape configuration about the first section. The last section is folded to extend horizontally to overlay part of the next module. The modules are anchored to an expanded metal wall at the "cold" side of the cover by an anchoring system which employs flat bars with spaced apart threaded studs welded to one flat side of the bar. In assembly, the studs are pierced through the mat at the junction of the first and second sections and then passed through openings in the expanded metal wall and secured by a washer and nut arrangement. The modules are then held by two bar-stud assemblies. The modules can be assembled by the process of laying down successive mats, securing them with anchoring assemblies, folding them in place and then repeating the process.
