节能已被列为当今世界上的第五大能源。热处理由于耗能特别大,因此,在热处理炉上寻求使用新型的节能材料,是一项有实际意义的工作。七十年代以来,国外已在许多热处理炉使用节能新材料——陶瓷纤维,近来我国也开始使用以硅酸铝耐火纤维为主的节能材料。硅酸铝耐火纤维具有导热系数低、耐高温、重量轻、比热小、热稳定性好、耐机械震动、高温绝缘等优良性能。热处理炉应用耐火纤维显示出保温性能好、升
Energy efficiency has been ranked as the fifth largest energy source in the world today. Heat treatment Due to the particularly large energy consumption, it is of practical significance to seek new energy-saving materials in heat-treating furnaces. Since the 1970s, foreign countries have been using energy-saving new materials - ceramic fibers in many heat treatment furnaces. Recently, China has also started to use energy-saving materials mainly based on alumina silicate refractory fibers. Aluminum silicate refractory fiber with low thermal conductivity, high temperature, light weight, small heat, good thermal stability, resistance to mechanical vibration, high temperature insulation and other excellent performance. Heat treatment furnace application of refractory fiber shows good insulation properties, l
