Description
Product Description of Low Creep High Alumina Bricks For Hot Blast Stove
Low creep high alumina bricks are refractory materials made primarily from bauxite, fused corundum, and fused mullite.
Low Creep High Alumina Bricks For Hot Blast Stove
Product Features of Low Creep High Alumina Bricks
1.Refractoriness
Low creep high alumina bricks have a refractoriness higher than clay bricks and semi-silica bricks, reaching 1750~1790°C, classifying them as refractory materials.
2.Load Softening Temperature
Due to the high Al2O3 content and low impurities, the formation of fusible glass phases is reduced, giving these bricks a higher load softening temperature than clay bricks. However, the absence of a network structure in mullite crystals results in a load softening temperature lower than that of silica bricks.
3.Slag Resistance
With a high Al2O3 content, these bricks are close to neutral refractory materials and can resist erosion by both acidic and basic slags. However, the presence of SiO2 makes their resistance to basic slag slightly weaker than to acidic slag.
Product Applications of Low Creep High Alumina Bricks For Hot Blast Stove
Primarily used in the construction of blast furnaces, hot blast stoves, electric furnace roofs, blow furnaces, reverberatory furnaces, and rotary kiln linings.
