Interior lining of refractory bricks for a tubular rotary furnaces and for this lining of refractory brick designed

摘要

In the lining according to the invention for rotary tubular furnaces, the refractory bricks (1) are connected to each other by a layer (2) of mortar and, on the cold side (5) of the brick, are at least intermittently bonded to the sheet metal shell (6) of the rotary tubular furnace by a layer (3) of adhesive. In order to prevent the penetration of mortar, mortar binder or water into the adhesive layer, and hence an impairment of the adhesive effect, spacer strips (8), made for example of cardboard, asbestos, sheet metal, insulating material or integrally with the brick from the material of the brick are arranged, in order to separate the mortar layer (2) from the adhesive layer (3), between the lateral surfaces (7, 9) of the bricks (1) which are connected by the mortar layer (2), in the region between the mortar layer (2) and the adhesive layer (3).
