从近几年应用耐火纤维的实践出发,提出对耐火纤维材质和应用技术的几个问题. 一、材质选用工业窑炉炉衬,长期经受高温、温度急变、炉渣浸蚀、机械冲刷及各种应力的综合作用,因而对炉衬材质提出了一系列特殊要求. 耐火纤维是一种新型轻质耐火材料.具有耐温、绝热、质轻及抗热震等优良性能,用作窑炉炉衬材质有明显的节能效果,但难以满足窑炉内上述特殊要求,因而有其应用的局限性.一般仅适用于没有强烈化学变化和机械磨损的窑炉.即使在这些窑炉内,也必须根据各部位具体工作条件选用不同的耐火纤维材质和品种,方能获得最佳技术经济效果.其次,对耐火纤
From the practice of refractory fiber in recent years, we put forward some questions about refractory fiber material and its application technology.First, the material selection of industrial furnace lining, long-term withstand high temperature, rapid temperature change, slag erosion, mechanical erosion and various stress A series of special requirements are put forward for the lining material.RF fiber is a new type of light refractory material with excellent properties of temperature resistance, heat insulation, light weight and thermal shock resistance, etc., Of the energy-saving effect, but it is difficult to meet the above-mentioned special requirements in the kiln, and therefore has its limitations. It is generally applicable only to those without strong chemical changes and mechanical wear. Even in these kilns, Working conditions selected different refractory fiber materials and varieties, in order to obtain the best technical and economic results.Secondly, the refractory fiber
