Product Details
Performance & Advantages:
High refractoriness;
Excellent chemical corrosion resistance;
Superior thermal shock stability;
Abrasion-resistant.
Applications:
High-alumina special-shaped bricks for roasting furnaces are widely used in multiple fields such as carbon, metallurgy, cement, lime, and steel.High-alumina shaped bricks are extensively utilized in various types of calcining and baking furnaces within the carbon industry (such as coke calcination kilns and carbon anode baking furnaces) and other industrial kilns, including forging furnaces, reheating furnaces, drying ovens, activated carbon furnaces, car-bottom furnaces, and annealing furnaces.
