Introduction：
High alumina refractories have excellent stability and service life in high temperature and chemically aggressive environments due to their high aluminum content and excellent refractory properties. This makes them an important choice for refractory structures in numerous industrial sectors. The aluminum content of high-alumina refractory materials is usually above 50%, and some varieties can even reach above 90%. High aluminum content endows this refractory with excellent refractory performance and corrosion resistance; high-alumina refractory has good high temperature resistance, and can still maintain good strength and stability in high temperature environments. They can withstand thermal stress and chemical corrosion in high-temperature furnaces, kilns and industrial equipment, and are suitable for refractory structures in high-temperature processes; high-alumina refractories are widely used in metallurgy, glass, cement, ceramics and chemical industries. They are often used in the lining, masonry, repair and protection of high-temperature kilns, refining furnaces, converters, electric furnaces and furnaces.
