ABSTRACT:
A roof assemblage for use in a furnace includes a refractory panel dimensioned to span refractory furnace walls and a wall bearing roof truss from which the refractory roof panel is suspended. The refractory roof panel is suspended by means of hangers which are connected to a bottom chord of the truss and to suspension bars which extend transversely of the roof panel. The truss is arranged intermediate of the width of the refractory roof panel and the bottom chord is situated on bearing anchors which connect the bottom chord at opposite ends thereof to the top of the refractory wall panels. Lifting hooks are provided on the top chord of the truss so that the truss-panel roof assemblage may be lifted as a unit onto and from the furnace walls.
