Abstract
A removable roof for a furnace in which metal is melted has a framework composed of a series of horizontal beams arranged in several layers, with the beams of the lowest layer being parallel to each other and being held in fixed and determined relation with respect to each other by the beams of the next layer. Anchors are attached to the beams of the lowest level, and a cast refractory fills the spaces between and around the anchors so that the refractory forms the downwardly presented face of the roof--the face which is exposed to the interior of the containment vessel. To construct the roof, the framework is fabricated and placed over a horizontal surface, whereupon the anchors are attached and a moldable refractory mix is introduced with the spaces between the anchors. The mix sets up into the refractory.
