Application of High Alumina White Fused Alumina in Refractories
White fused alumina is an advanced refractory material. With the continuous development of modern high-temperature industrial technology and equipment, especially in recent years, the application of new technologies in the metallurgical industry has further promoted the adjustment of refractory materials and structures. The proportion of refractory materials used is also increasing.
Because adding an appropriate amount of white fused alumina has good high temperature resistance and thermal stability, it can appropriately increase the density of the castable. We know that white corundum can also form mullite with micro-silica at high temperatures, which improves the high-temperature strength of the castable.
White white fused alumina plays an important role in the improvement of shaped and unshaped refractories in the refractory industry.
It is filled in the pores of the refractory material to increase the bulk density, reduce the apparent porosity and increase the strength significantly.
It has strong activity. Colloidal particles are formed in water. Adding an appropriate amount of dispersant can enhance its fluidity and improve the performance of the castable.
It has strong hydrophilic properties and enhances the agglomeration of refractory materials.
At the same time, it has a greater improvement in high temperature resistance and can extend refractory products. Service life.
Application industry:
It is widely used in steel, cement, ceramics, petroleum and other industries. It is an ideal material for the production of large ladle castables, medium and high-grade iron trough castables, gunning materials, prefabricated parts and other amorphous refractory materials, corundum bricks, corundum and mullite corundum mortar, corundum porous plug bricks for refining, integral spray guns, composite The main raw material for corundum products such as nozzles and lining materials for high-temperature industrial furnaces.
