Fire Resistant SK34 Refractory Brick Furnace Lining Bricks Thermal Stability 1790°C
Description of Fire Resistant SK34/36 Refractory Brick For Furnace Lining With Thermal Stability 1790℃
High alumina brick, an alumina-silicate refractory material, is formulated with an alumina oxide content surpassing 48%. It is manufactured through the calcination and shaping of bauxite or materials abundant in AL2O3. Demonstrating extraordinary thermal stability, it attains a refractoriness surpassing 1770℃. Its remarkable resistance to slag makes it a prime choice for lining steelmaking electric furnaces, glass kilns, and cement rotary kilns.
