- 38-42% Fire Alumina Refractories

Our Super Duty & High Density fire bricks are manufactured by dry press process. These bricks are high abrasion resistant. These bricks contain a high proportion of Pre-Calcined material resulting in a product with good dimensional tolerance. The tight texture and low flux content give good resistance to slag attack, alkali attack and vitrification.

Super Duty bricks has high alkali resistance and finds use in Regenerators both as hot face and as a back up in insulated wall construction.
