Magnesia-iron-aluminum spinel bricks for cement rotary kiln firing zone,Refractory Bricks using high-purity magnesia and iron-aluminum spinel; process: reasonable gradation, high-pressure molding,Refractory Bricks strict control of firing temperature and firing atmosphere;Refractory Bricks transition zone with magnesium-aluminum tip Spar bricks use high-purity magnesia and synthetic magnesia-aluminum spinel as the main raw materials. The main crystal phases are periclase and spinel. This refractory brick has good corrosion resistance,Refractory Bricks spalling resistance and high temperature resistance. It can be used for large The transition zone of dry-process cement rotary kiln.
Refractory brick configuration for cement rotary kiln: kiln-mouth brick,Refractory Bricks high wear-resisting brick fused magnesia-aluminum-spinel brick; lower transition zone,Refractory Bricks unstable area of kiln skin behind kiln-mouth brick, magnesia-aluminum spinel brick; firing zone, Kiln skin stable area,Refractory Bricks directly combined with magnesia-chrome brick, magnesia-iron spinel brick, magnesia-aluminum spinel brick, dolomite brick; upper transition zone,Refractory Bricks unstable kiln skin area, magnesia-aluminum spinel brick; safety belt, 10 meters behind the upper transition zone,Refractory Bricks silica-mold brick 1680; preheating the decomposition zone, after the safety belt, to the end of the kiln,Refractory Bricks silica-mold brick 1650 anti-stripping high alumina brick.
