1. We are a specialized manufacturer and exporter of refractory. We mainly export to America, Canada, UK, India etc.
2. For high alumina brick, the content of Al2O3: 50~85%. High alumina brick have very good ability of anti-acidity, anti-metal fluid corrode and anti-oxidation. High alumina brick are used normally in industry furnaces such as Blast furnace, hot-blast furnace and EAF etc. High alumina bricks are widely used for Metallurgy metallurgy, steel, alumina, cement, glass, electric furnace, chemical industry, electric power etc.
3. The specifications for 80 high alumina brick Al2O3≥ 82.5% Fe2O3 ≤ 2.0% SiO2≤ 11.5% Linear change after reheating 0~-0.5% Bulk density ≥ 2.70g/cm3 Apparent porosity≤ 23% Cold crushing srength≥ 70MPa
4. We can produce common shaped and irregular shaped refractory brick. Specifications can be adjust as your application We ensure the high quality and competitive price
