Special-Shaped High-Aluminum Anchor Bricks and Hanging Bricks
High alumina bricks can be said to be one of the most widely used refractory bricks in the refractory industry. High alumina bricks are available in hundreds of specifications and sizes and can be used in various thermal kilns in the steel industry, building materials industry, electric power industry, etc. Generally speaking, aluminum silicate refractory materials with an Al2O3 content greater than 48% are collectively referred to as high-aluminum refractory materials, and the final products are commonly used high-alumina bricks. High alumina bricks can also be made into special-shaped products according to the actual masonry needs of industrial furnaces, such as high alumina anchor bricks and hanging bricks, which are used on the furnace roof or side walls.
Rongsheng Manufacturer Customized High Alumina Brick Specifications
High alumina brick models and specifications. Rongsheng high alumina brick manufacturers have complete specifications and models, and can also be customized according to the actual use needs of industrial furnaces.
The refractoriness of high alumina bricks fluctuates widely, generally between 1770 and 2000°C, and is mainly affected by the Al2O3 content. It increases with the increase of Al2O3 content in the product. At the same time, the refractoriness is also affected by the content and type of impurities and is related to the mineral structure of the product.
The softening deformation temperature of high alumina bricks under load is greater than 1400°C and increases with the increase of Al2O3 content. For products with an Al2O3 content of less than 71.8%, the load softening temperature depends on the quantity ratio of mullite and glass phases and increases with the increase in the quantity of mullite. The amount and nature of the glass phase have a significant impact on the load softening point. When the Al2O3 content is 71.8% to 90%, it is a mullite or corundum product. As the Al2O3 content increases, the glass phase volume remains unchanged. Although corundum has increased, mullite has decreased, so the load softening temperature does not increase significantly. After the Al2O3 content exceeds 90%, as the Al2O3 content increases, the number of glass phases decreases and the load softening temperature increases significantly. It rises from 1630℃ when the Al2O3 content is 90% to 1900℃ when the Al2O3 content is 100%. The load softening temperature increases with the increase of Al2O3 content.
In summary, the thermal conductivity of high alumina bricks decreases as the temperature increases. When the Al2O3 content in high alumina bricks is higher, the more mullite and corundum crystals there are, the more obvious the tendency of thermal conductivity to decrease as the temperature increases. But above 1000℃, the decrease rate decreases.
Special-Shaped High Alumina Bricks-High Alumina Anchor Bricks
High alumina anchor bricks are refractory bricks used in heating furnaces. High alumina anchor bricks are also called hanging bricks. They are mainly used to connect and support the structure of refractory bricks and ordinary fired bricks for heating furnace roof walls or other components.
High-aluminum anchor bricks use natural high-grade bauxite as the main refractory raw material and add soft or semi-soft clay as a binder to high-aluminum clinker. Start with ingredients, mixing, shaping, drying, and finally firing. Formed high alumina refractory bricks. Generally, the alumina content of high-alumina anchor bricks is above 55%. High-aluminum anchor bricks can be produced and processed according to customer needs. The load-softening temperature of high-aluminum anchor bricks can reach 1550°C, which can meet the performance requirements of the heating furnace roof lining.
Characteristics of High-Aluminum Anchor Bricks for Heating Furnaces
1. Volume stability at high temperatures.
2. Good corrosion resistance.
3. High softening temperature under load.
4. Anti-peeling and high compressive strength.
High Aluminum Anchor Brick Hanging Brick
High-aluminum anchor brick is a special-shaped high-alumina refractory brick, including a column composed of a hanging end and an anchor body. Spaced separation grooves are provided on the surface of the anchor body along the length direction of at least one surface of the anchor body. Due to the reinforcement and traction effect of the ribs, the tensile and flexural strength of the anchor is significantly increased. The stress generated at the groove is blocked by the ribs and cannot be transmitted further, so https://highaluminarefractory.com/high-alumina-anchor-bricks is not easy to break.
High-aluminum anchor bricks for heating furnaces. High alumina anchor bricks are refractory bricks used in the roof walls of heating furnaces. The size can be customized according to the needs of the heating furnace. The high-aluminum refractory brick products of Rongsheng Refractory Materials Manufacturer can not only meet the needs of heating furnace linings and ensure the service life of heating furnace linings but also help enterprises improve the economic benefits of heating furnaces.
