耐火纤维是一种新型轻质耐火材料。冶金部洛阳耐火材料研究所于1977年开始研制耐火纤维,到1980年先后研制成功四种耐火纤维。1 高纯硅酸铝纤维。采用工业氧化铝和硅石作原料,经合成团块、电弧炉熔融吹成纤,并制成制品。主要理化指标:AI_2O_2+SiO_2>99%;1260℃×6小时加热线收缩率小于3%。可长期使用于1100℃以 Refractory fiber is a new type of lightweight refractory material. Research Institute of Refractories Luoyang Ministry of Metallurgical began developing refractory fibers in 1977, has successfully developed in 1980 four kinds of refractory fibers. 1 high purity aluminum silicate fiber. Using industrial alumina and silica as raw materials, the synthesis of clumps, electric arc furnace melt blown fiber, and made of products. The main physical and chemical indicators: AI_2O_2 + SiO_2> 99%; 1260 ℃ × 6 hours shrinkage of the heating wire is less than 3%. Long-term use at 1100 ℃
