Alkali-resistant bricks for cement kiln are made of chamotte,silica and low alumina refractory clay.They have merits like excellent resistance to alkali,good permeability.They are widely used in the preheater of cement kiln,decomposing furnace,teritary air tubes and so on.
Peel-off resistant alumina bricks are made of bauxite,fired at high temperature and mold by high pressure,the product has excellent resistance to spalling and corrosion resistant,can be used in cement kiln door enclosures,cooling machine parts and so on.
Phosphate cement kiln combined with high alumina brick is made of dense bauxite,mixed by binder of phosphate and phosphate salts,mold by high pressure and proceed by proper temperature.The product is characterized by their good thermal stability and resistance to corrosion and excellent wear-resistance.It can be used in rotary kiln preheating zone,decomposition zone,kiln door cover and cooler’s lining etc.
Silicon-mullite bricks are made of mullite powder and carborundum mold by high-pressure and fired by high temperature.The products are characterized with high strength,strong ability of anti-corrosion and excellent thermal stability.They can be used in transition zone,cooling zone and kiln mouth of cement rotary kilns etc.
