ABSTRACT:
A refractory brick panel module and suspended roof construction for high temperature furnaces wherein the panel module has a refractory support frame of at least two substantially parallel support members with at least one end of the support members having extension and retraction means forming an extendable and retractable refractory support frame end portion. The refractory support frame end portion in retracted position allows passage of the refractory support frame between adjacent roof support beams and in extended position provides refractory brick suspension beneath the roof support beams to a proximity to adjacent roof panel modules. The extendable and retractable refractory support frame allows great flexibility in modular suspended roof construction, providing easy repair of either entire modules or replacement of a relatively small number of refractory bricks from the cold side of the furnace roof.
