Abstract
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.
