Special refractory brick series - dense wear-resistant high alumina brick for lime kiln
T3 standard brick, 230*114*65 (size can be processed and customized according to the drawing)
Dense and wear-resistant high alumina bricks are made by adding specific raw materials on the basis of ordinary high alumina bricks. The product has good stability and the degree of corrosion resistance does not change suddenly. The service life is 2 times higher than that of ordinary grade III high alumina bricks which greatly improves the sintering thermal efficiency of the kiln. Therefore, it is often used in environments with chemical corrosion and large temperature fluctuations, such as steel hot blast furnace, glass kiln, chemical and other industries. Dense and wear-resistant high alumina bricks have low porosity, improved wear resistance corrosion resistance, and have price advantages compared with low porosity clay bricks. It can be used in heating furnaces, glass kilns, lime kilns, and be used in the upper and lower material ends of vertical lime kilns, greatly reducing the shedding of refractory bricks, improving wear resistance, and reducing the cost corporate benefits.
