refractory bricks for heating furnace lining
High alumina refractory bricks is a kind of refractory material, the main component of this refractory brick is AL2O3. According to the content of Al2O3 in High alumina refractory bricks, it is usually divided into three grades: Grade I:Al2O3 content>75%; Grade II:Al2O3 content is 60~75%; Grade III:Al2O3 content is 48-60%.

Raw material of High alumina refractory bricks
According to different resource conditions and product requirements, the following types of raw materials can be used: It is mainly composed of high alumina bauxite; sillimanite group minerals (including kyanite, andalusite, sillimanite, etc.); synthetic raw materials such as industrial alumina, synthetic mullite, fused corundum, etc.
Uses of High alumina refractory bricks
High alumina refractory bricks are mainly used for lining blast furnaces, hot blast stoves, electric furnace roofs, blast furnaces, reverberatory furnaces, and rotary kilns. In addition, High alumina refractory bricks are also widely used as open hearth regenerative checker bricks, plugs for pouring systems, nozzle bricks, etc. However, the price of High alumina refractory bricks is higher than that of clay bricks, so it is not necessary to use High alumina refractory bricks where clay bricks can meet the requirements.
Characteristics of High alumina refractory bricks
1. Refractoriness of High alumina refractory bricks
The refractoriness of High alumina refractory bricks is higher than that of clay bricks and semi-silica bricks, reaching 1750~1790℃, which belongs to advanced refractory materials.
2. Load softening temperature of High alumina refractory bricks
Because high-alumina products have high Al2O3, less impurities, and less fusible glass, the load softening temperature is higher than that of clay bricks. However, because mullite crystals do not form a network structure, the load softening temperature is still not as high as that of silica bricks.
3. Slag resistance of High alumina refractory bricks
High alumina refractory bricks contain more Al2O3, which is close to neutral refractory materials, and can resist the erosion of acidic slag and alkaline slag. Because it contains SiO2, the ability to resist alkaline slag is weaker than that of acidic slag.
Packaging of High alumina refractory bricks
1.on wooden pallets with plastic cover: wooden pallet size :930*930 or 1000*1000mm,
2.Load weight of each pallet: 1.5-2.0 tons,
3.230*114*65mm:512PCS/Pallet, 230*114*75mm:448PCS/Pallet.
