(57) The invention belongs to the technical field of refractory materials, and particularly relates to a hanging top brick for a cement kiln head cover. The tophung brick structurally comprises the brick body, the inverted-T-shaped groove, the connecting piece unit, the inverted-Tshaped block and the exposed steel fiber, a mold for forming the top-hung brick comprises the auxiliary mold unit and the main mold unit, the top-hung brick is installed in a suspended mode in a multilayer staggered mode inside and outside,and finally it is guaranteed that the fireproof and heat insulation effects of the top-hung brick are outstanding, and the effective service life is long. The top hanging brick has the advantages that the top hanging brick is spliced and suspended in a vertical end face splicing mode, an inclined end face is separated left and right, arc-shaped faces are properly separated up and down, at least one of the two splicing faces is provided with exposed steel fibers, and compared with the mode that the splicing faces are directly attached, a proper space is reserved, and the top hanging brick is convenient to assemble and disassemble. The device is used for carrying out essential mechanical vibration and thermal deformation on the hanging top bricks, and the hanging top bricks are prevented from frequent vibration crushing and deformation extrusion crushing.

Basic kiln hoods – successful and innovative refractory concepts

The kiln hood of a rotary kiln in a cement plant connects the hot area of the kiln with the clinker cooler and is therefore always exposed to high thermal and process-related stresses. In recent decades, these loads have steadily increased in consequence of the use of alternative fuels and thereby induced higher process temperatures. For system builders, this means an enormous design effort, when rotary kilns are modernized.
