4 diameter 95% 96% Alumina Ceramic Bar
Reputation depends on quality, quality comes from Hard!
Alumina Ceramic:
Roller kiln has the characteristics of small firing temperature difference, short firing cycle, high yield, low energy consumption and easy control. It is used in building sanitary ceramics (especially wall tiles and sanitary ware), daily porcelain, special ceramics and iron. Oxygen production, as well as glass and metal annealing industries are widely used. As the application range of roller kiln is expanding, the requirements for the manufacturing technology of the roller kiln and the refractory materials used are constantly increasing. In the roller kiln, the roller bar is the most critical refractory material, which plays the role of carrying and conveying products in the kiln, that is, the strength and high temperature mechanical properties of the roller bar determine the use temperature and load of the roller kiln, and then The range of use of the roller kiln is determined, so researching and improving the performance of the roller bar is the key to the further promotion and application of the roller kiln. Ceramic roller bar for roller kiln in the glass ceramic industry. The main function of the ceramic roller is to transport ceramic or glass products, high temperature and high heat, and it is necessary to clean the surface of the roller. At present, the most widely used ceramic roller rods are alumina corundum ceramic rollers. (also known as corundum roller, kiln roller, ceramic kiln roller, ceramic plate, corundum bar, kiln bar, conveyor roller), high temperature resistant and high heat resistant, curved ceramic roller (curved roller bar) Roller) improves the efficiency of the kiln product.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
