Reheating Furnace SK-37 1770C Alumina Refractory Bricks
Description Of Alumina Refractory Bricks
Alumina Refractory 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.
Application of Alumina Refractory Bricks
Metallurgy, Nonferrous Metal Furnace, Ammonia, Chemical industry
