Product presentation
The mineral composition of high-alumina refractory bricks is corundum, mullite and glass phase, and its content depends on the ratio of AL2O3/SiO2 and the type and amount of impurities. The grade of refractory bricks can be divided according to the content of AL2O3. The raw materials are natural ores of high-alumina bauxite and sillimanite, and there are also those mixed with fused corundum, sintered alumina, synthetic mullite, and clinker calcined with alumina and clay in different proportions. It is mostly produced by sintering method. But the products also include fused cast bricks, fused granular bricks, unfired bricks and amorphous refractory bricks. High-alumina refractory bricks are widely used in the steel industry, non-ferrous metal industry and other industries.
Physical and chemical properties
1. Wear resistance:
2. Thermal conductivity: The heat flow rate per unit area of the material under unit temperature gradient conditions, which is related to the porosity
3. Impact resistance: No need to explain, good impact resistance means long service life
4. Slag resistance: The ability to resist slag erosion without being destroyed at high temperatures
Product features
One of the important working properties of high alumina refractory bricks is the structural strength at high temperature, which is usually evaluated by the load softening deformation temperature. Its high temperature creep is also measured to reflect its high temperature structural strength. The test results show that the load softening temperature increases with the increase of Al2O3 content.
The public properties of refractory raw materials mainly depend on the mineral composition and particle composition of the raw materials, and are closely related to the manufacturing process of refractory materials. Such properties mainly include particle size and particle size distribution, fineness and specific surface area, plasticity and bonding, drying shrinkage and firing shrinkage, sintering temperature and sintering range, etc.
