Aluminum silicate refractory bricks containing more than 48%-82% alumina are called high alumina bricks. They can be divided according to the Al2O3 content level, or the refractory product use and use characteristics, as well as light products and heavy materials. Products, etc.
1. According to the Al2O3 content grade: 48-50% of common products, 55-60% of high-grade aluminum, 65-70% of high-grade aluminum, 75% of first grade and ≥82% of special high alumina brick;
2. Product use: high aluminum products for glass kiln, high aluminum products for hot blast stove, high aluminum products for power plant boilers, cement kiln, chemical, environmental protection, high alumina brick products for metallurgy, etc.
3. The use of features: low creep high alumina products, anti-flaking high aluminum products, phosphate combined with high alumina bricks.
4. Specific gravity: 0.6-1.0 high alumina poly light insulation brick, 1.2-1.6 medium quality blast furnace refractory brick, heavy high aluminum product between 2.2-2.8.
