多晶耐火纤维因其热容低、热导率低、热敏性好等特点,作为保温绝热材料,一些先进国家正广泛应用于各种高温工业炉窑等热工设备。它的应用在降低能耗、提高炉窑的技术装备水平和各项经济指标方面,具有十分明显的成效。多晶耐火纤维因氧化铝含量不同,目前国际上有三个品种:一是英国产,Al_2O_3含量95％;二是日本产,Al_2O_3含量80％;三是美国产,Al_2O_3含量72％。我国参照国外资料目前也生产以上三种多晶纤维,虽然本体质量与国外产品尚有一定差距,但总算有
Due to its low heat capacity, low thermal conductivity and good thermal sensitivity, polycrystalline refractory fiber is widely used in thermal industrial furnaces and other thermal equipment as thermal insulation materials. Its application has obvious effect in reducing energy consumption, raising technical and technological level of furnace and various economic indicators. Polymorph refractory fiber due to different alumina content, there are three varieties of the international community: First, the United Kingdom, Al_2O_3 content of 95%; Second, Japan, Al_2O_3 content of 80%; Third, the United States, Al_2O_3 content of 72%. At present, China also produces more than three kinds of polycrystalline fibers with reference to foreign materials. Although there is still a certain gap between the ontology quality and foreign products,
