Low Creep Ratio High Aluminum Bricks are produced with selected bauxite chamotte by advanced process and strict quality control. The main mineral components are corundum and mullite phases. Its features are excellent high temperature mechanics and chemical corrosion resistance.
Low Creep Ratio High Aluminum Bricks the main chemical components: Al2O3 content is 30%-48%, SiO2 content is 50%-65%, and a small number of alkali metals, alkaline earth metal oxides, etc. Mineral composition is usually mullite, quartz and glass phase. Its refractoriness is 1580-1750℃, refractoriness under load is 1250-1450 ℃, line expansion coefficients is low, with good thermal shock resistance and strong ability to resist erosion acid slag.
Low Creep Ratio High Aluminum Bricks Usually mixing high alumina bauxite plus a small amount of clay ,after grinding with gas or foam to form mud casting ,forming 1300 ~ 1500℃ firing. Sometimes can also be used to replace part of industrial alumina bauxite .
Production practice in China has proved that before crushing, high-aluminum clinker is strictly sorted and classified, and stored in tiers.
The use of bauxite clinker and combined clay fine grinding method can improve product quality.
