Alumina ceramic guide plate Because of its excellent properties, alumina ceramics have been widely used in many industries in the national economy. Alumina ceramics is a general term for ceramic products made of calcined alumina as the main raw material. Due to the different content of alumina, it is divided into 75 porcelain, 85 porcelain, 90 porcelain, 95 porcelain, 97 porcelain and 99 porcelain. The main raw material of calcined alumina is mainly industrial alumina, aluminum hydroxide or boehmite, which is calcined at 1300-1500°C. The raw material processing methods of alumina ceramics mainly include dry method and wet method. The dry method mainly uses a roller ball mill for dry grinding, and the wet method mainly uses a roller ball mill, agitating mill, and a sand mill. The alumina ceramic guide plate is made of alumina ceramics.

Alumina ceramic materials have relatively stable physical and chemical stability. The physical stability is mainly manifested in the aspects of high and low temperature resistance, insulation, anti-magnetic, and abrasion resistance; the main surface of the chemical stability is corrosion resistance and oxidation resistance. The molding methods of alumina ceramics mainly include grouting, hot die casting, film rolling, dry pressing, isostatic pressing, casting, injection and gel injection molding, etc. Different molding methods correspond to different processes. The raw materials for hot die casting and rolling film The processing method is mainly dry grinding, and the raw material processing methods of grouting, dry pressing and isostatic pressing are mainly wet grinding. Although the performance of alumina ceramic guide block is excellent, it is still difficult to manufacture.
