Abstract (en)

A stave protection system for a metallurgical furnace comprises: a stave (100) comprising upper and lower ribs (114) projecting forwardly from a front face (102) of the stave (100) and spaced apart from each other so as to define a transverse groove (112); at least one insert (200) partially located in the groove (112) and fixedly engaged with the upper and lower ribs (114) so as to project forwardly thereof; and a brace (300; 400) located between a front surface (114a) of the lower rib (114) and an opposing rear surface (212) of the insert (200), such that in use the brace (300; 400) opposes a force (FD, FL, FR) applied to the insert (200) so as to resist displacement of the opposing rear surface (212) of the insert (200) toward the front surface (114a) of the lower rib (114).
