Descripton of High Oxide Aluminium Standard Refractory Brick
With Temperature Resistance 1770℃
High Alumina Bricks, crafted from premium-grade raw materials with
an alumina content exceeding 48%, are the epitome of superior
refractory materials. These bricks boast exceptional thermal
stability and refractoriness, withstanding temperatures in excess
of 1770℃. Renowned for their high strength and resistance to acid
and erosion, they find applications in diverse industries including
cement, glass, steel, and petrochemicals. With a composition
tailored for neutral refractoriness, they ensure reliable
performance in environments exceeding 1300 degrees centigrade.
Explore our range of High Alumina Bricks, meticulously engineered
to meet the stringent demands of high-temperature technology.
