Abstract (en)
A refractory furnace brick (1) (1/2) has chamfered corner faces (F3/f3) enabling the bricks to be formed into a regular grid with longitudinal rectangular bores formed both within respective bricks and defined by surrounding bricks. Preferably the shorter sidewalls of the bricks are extended slightly in the transverse direction to form ridges R/R' which interlock to strengthen the structure. In order to provide a distributed expansion flexible ceramic pads (P) may be provided between the chamfered corner faces.
