耐磨浇注料强度高,高温性能良好,体积稳定,导热系数小,康熔渣参透性和侵蚀性极强,耐冲刷,施工方便,炉体结构整体性强等特点,是目前流化床锅炉使用的一种抗磨材料,比传统浇注料,可大大提高锅炉运行时间。
The construction body of the circulating fluidized bed power generating boiler is extremely complicated, with a large amount of construction. The pulverized coal flow rate in the system pipeline is high, and the flow velocity is high. The refractory material used for the lining is required to have high strength, good wear resistance, and excellent construction. The wear-resistant castable has high strength, good high-temperature performance, stable volume, small thermal conductivity, strong permeability and erosion of Kang slag, erosion resistance, convenient construction, and strong integrity of the furnace structure. It is the current fluidized bed boiler. An anti-wear material is used, which can greatly improve the boiler operating time than traditional castables.
