A binding system for applying a vertical compressive force to the refractory walls of a rectangular or circular furnace comprises a compressive member engaging a laterally extending surface of the furnace wall and a support member to which the compressive member is connected. The compressive member preferably comprises a coil spring which acts directly on the laterally extending surface or indirectly through a force-applying member. The force applied by the compressive member is sufficient to control vertical expansion and substantially prevent vertical expansion of the furnace walls due to infiltration of material into the joints between the refractory bricks during operation of the furnace.

System for applying vertical compressive force to furnace walls

A system for supporting and cooling a furnace roof comprised of refractory bricks comprises a plurality of roof support members extending across the furnace and being supported from above the furnace roof. The support members are provided with internal channels for circulation of a cooling fluid, and are provided with side surfaces adapted to support rows or refractory bricks between adjacent roof support members. The system eliminates the need to suspend individual bricks from above the roof, and provides simultaneous support and cooling of the roof structure.
