Description of Anti-stripping High Alumina Brick:
Anti-stripping high alumina bricks have excellent thermal shock resistance and spalling resistance, as well as alkali, sulfur, and chlorine corrosion resistance. At the same time, with high refractoriness under load and high strength at high temperatures, anti-stripping high alumina bricks also have good alkali resistance and cement clinker corrosion resistance.
