A large number of wholesale high-alumina refractory bricks
High alumina brick refers to an aluminum silicate refractory material with Al2O3 content of 48% or more.
Usually generally divided into three categories: I, etc.: Al2O3 content ≥ 75%; II, etc.: Al2O3 content 60% ~ 75%; III, etc.: Al2O3 content 48% ~ 60%; can also be classified according to its mineral composition, generally divided into : Low mullite, mullite, mullite - corundum, corundum - mullite and corundum. Its mineral composition is mainly corundum, mullite and glass phase. The softening temperature of high alumina refractory bricks increases with the increase of Al2O3 content.
High-aluminum bricks are widely used as open-hearth regenerative lattice bricks, plugs for sprue systems, and nozzle bricks. However, the price of high-alumina bricks is higher than that of clay bricks, so it is not necessary to use high-alumina bricks where clay bricks can meet the requirements.
a, refractoriness up to 1750~1790 °C
b, load softening temperature, load softening temperature is higher than clay brick
c. Slag resistance High Al2O3 has more Al2O3, close to neutral refractory material, and can resist the erosion of acid slag and alkaline slag.
