摘　　要：为了节约能源、改善操作环境、提高炉体寿命,莱钢板带厂在加热炉上试用了多晶莫来石纤维。多晶莫来石纤维具有低热容、低导热率、低容重、热敏性能好、高辐射能力等特点,加热炉采用该材料后,炉体外表面温度平均下降了34.8℃,降低了加热炉能耗,提高了热效率。In order to save energy and improve operational condition and increase the life of furnace body, the polycrystalline mullite fibre was used in the heating furnace in the sheet strip plant of Laiwu steel. The pelycrystalline mullite fibre has many characteristics such as low thermal capacity, low heat conductivity, low volume-weight, good hot sensitivity and high radiation abihty etc. After adopting this material, the outer surface temperature of the body was decreased by 34.8℃ averagely, reducing energy consumption of the heating furnace and increasing thermal efficiency.
