The Description of High Alumina Bircks:
High alumina brick is one kind of neutral refractory material, not only has certain corrosion resistance to acidic and alkaline slag, but also has the characteristics of high cold crushing strength, erosion resistance, strong penetration resistance, and high refractoriness under load.
