High Alumina Insulation Bricks For Hot Blast Furnace
This product is manufactured using foam rapid-setting technology, featuring low bulk density, high compressive strength, high refractoriness under load, minimal dimensional tolerance, and excellent thermal stability. It has a stable thermal conductivity, which is the best among all insulating refractory bricks available. It effectively reduces the overall weight of the furnace, decreases the thickness of furnace walls, improves thermal efficiency, lowers energy consumption, enhances working conditions, and increases production efficiency, resulting in significant economic benefits. It is widely used in the insulation layer of various thermal processing equipment and as lining in areas not subjected to severe erosion by high-temperature molten materials.
