High Alumina Lining Bricks SK38 For Thermal
Equipment Lining Use
High Alumina Lining Bricks is a kind of refractory material. The
main component of this refractory brick is AL2O3. Aluminum silicate
refractory products with aluminum oxide (Al2O3) content higher than
48%.
High thermal stability, fire resistance above 1770 ℃. It has good
slag resistance and is used for lining steel-making electric
furnaces, glass melting furnaces, cement rotary furnaces, etc.
According to the content of Al2O3 in High Alumina Lining Bricks
SK38 For Thermal Equipment Lining Use, it is usually divided into
three grades:
Level Ⅰ-Al2O3 content >75%;
Grade Ⅱ-Al2O3 content is 60~75%;
Grade Ⅲ-Al2O3 content is 48~60%.
