High alumina brick
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.
