1, Refractory bricks characters: 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. 2. Appllicaions. Widely used for lining of acid kiln, also used for blast furnace, hot blast furnace, glass kiln and high temperature kiln such as carbon baking kiln. 3. Physical and Chemical Index.
