High alumina bricks can be said to be one of the most widely used refractory bricks in the refractory industry. There are hundreds of specifications and sizes of high alumina bricks, which can be used in a variety of thermal kilns such as the steel industry, building materials industry, and power industry.
Generally speaking, aluminum silicate refractories with AlO content greater than 48% are collectively referred to as high-alumina refractories. The finalized products are commonly used high-alumina bricks, which are generally divided into three grades: Ⅰ and other: AlO75%; Class Ⅱ: AlO60% 75%; Class Ⅲ: AlO 48% 60%.
Fire a high-alumina refractory brick, usually at a firing temperature of 1500 to 1600°C;
Firing secondary high-alumina refractory bricks, usually firing temperature is 1450 to 1500 ℃;
Fire three-level high-alumina refractory bricks, usually at a firing temperature of 1350 to 1450°C;
