Chrome corundum refractory plastic is a high-end refractory material specially designed for large circulating fluidized bed boilers. It is mainly composed of chromium oxide and corundum, has a high melting point and high hardness, and has excellent volume stability at high temperatures without expansion or contraction. In addition, the material shows extremely strong wear resistance and high temperature resistance, can effectively resist the erosion of acidic and alkaline gases, and prevents reaction with slag. Due to its superior wear resistance and high temperature resistance, this material is widely used in high-wear parts of circulating fluidized bed boilers, such as cyclones, furnace exits and furnace dense phase areas. In practical applications, this material significantly extends the life of the boiler. For example, in the fluidized bed boiler project of a large thermal power plant, after using chromium corundum refractory plastic, the furnace lining did not stop due to quality problems within four years, which greatly improved the reliability and stability of equipment operation. . Chrome corundum refractory plastic has therefore become an indispensable key material in high-temperature kiln engineering, helping companies achieve efficient and stable operations in high-temperature processes.
