The Difference Of Fused Cast AZS Block And Fire Clay Bricks

Date:2015-11-20 16:32 | From:Zhengzhou Sunrise Refractory | Author:admin
Fused cast AZS block is made of pure alumina powder and zircon sand and produced through casting technology method which is by melting the raw material in the electric furnace, then casting into various molds and cooling themselves down to become white solid. The petrographic structure of fused cast azs block is composed of eutectoid of zirconium corundum and plagioclase, and glass phase. Fused cast AZS block is mainly applied to all the melting pool where directly gets in touch with the glass liquid such sidewall, paving of working end, doghouse bricks, super structure, fore hearth, throat, bubbling brick, corner brick, etc.

The main raw material of fire clay bricks is clay which is through mud processing, molding, drying and roasting. Fire clay bricks made in China are mainly made of kaolinite(Al2O3•2SiO2•2H2O) and 6%~7% impurities(oxide of potassium, sodium, calcium, titanium and iron). The content of Al2O3 is usually above 40% and Fe2O3 is below 2.0~2.5%. Fire clay bricks adopt 50% soft clay and 50% hard clay clinker, ingredient by a certain size, and sinter under high temperature of 1300~1400℃ after forming and drying. Fire clay bricks are the weak acid refractory products which can resist acid melting slag and the erosion of acid gas, good thermal property and resist rapid heat and cold. Fire clay bricks are mainly used in the secondary parts of coke oven, such as regenerator seal wall, small flue lining bricks and regenerator, door lining brick, roof and riser lining brick.
