摘　　要：无碱玻璃纤维由于良好的耐水性,良好的电绝缘性和机械强度等优点,在玻璃纤维产业中所占的比例越来越大。无碱玻璃池窑拉丝是当今世界玻璃纤维工业最先进的生产方法,而单元窑是熔制难熔优质玻璃的首选窑型,由于无碱玻璃纤维熔制温度在1540℃以上,所以对所用耐火材料的要求也十分苛刻。本文综述了无碱玻璃纤维行业及其所用耐火材料现状,指出了在当前形势下,致密氧化铬砖仍是无碱玻璃纤维池窑关键部位的首选耐火材料。Non-alkali glass fiber occupies more and more percentage in the glass fiber industry because it has good water resistance, insulation property and high mechanical strength and so on. The fiber drawing of non-alkali fiber industry is the most advanced production process for present glass fiber industries in the world at present. The unit glass tank furnace is the tank furnace to be first selected for the difficult melting glass. Because the temperature for the non-alkali glass fiber melting is at the tempera-tures over 1540℃, the requirement to refractories is very severe. The present situation of non-alkali glass fiber industry and its applied refractories are described in the paper. It is pointed out that at present conditions, the dense chrome oxide bricks are the first selected refractory for key locations of the non-alkali fiber tank furnace.
