Product Description
High Alumina Brick
High alumina brick is made from high alumina crog, which is chosen, screened and high temperature sintered. This kind of production's acid-resistance, alkali-resistance are good. And the refractoriness is high. It can be used in blast furnace, hot-blast stove, the roof of electric stove and ladle backing layer.
