耐火纤维炉衬新技术是工业炉节能节电的有效途径之一。与传统的砖砌炉衬相比,其具有蓄热少,散热弱,重量轻,炉墙薄,占地小,效率高,抗热震,耐振动,易施工,便维修等一系列优点。在国际上被誉之为“工业炉结构的巨大革命”。六十年代中期以来,各主要工业国家竞相发展,应用广泛,全世界迄今已有数逾万计的各种类型的耐火纤维炉衬工业窑炉。我国自七十年代后期开始发展这一节能技术,起步稍晚,进展迅速,目前沪、津、京、宁、渝等地均已陆续推广使用,其它省市也正迎头赶上。仅以上海一地为例,截止1980年8月,已有1164座电加热炉完成了耐火纤维炉衬改造,总功率达33964 Refractory fiber lining new technology is an effective way to save energy and save electricity in industrial furnaces. Compared with the traditional brick lining, it has a series of advantages of less heat storage, less heat dissipation, light weight, thin wall, small footprint, high efficiency, thermal shock resistance, vibration resistance, easy construction and maintenance. In the international arena as “a huge revolution in industrial furnace structure.” Since the mid-1960s, all major industrialized countries have competed for development and are widely used. To date, there have been more than tens of thousands of refractory fiber lining industrial kilns in the world. Since the late 1970s China started to develop this energy-saving technology, which started a little later and has made rapid progress. At present, Shanghai, Tianjin, Beijing, Ningxia and Chongqing have been gradually promoted and used. Other provinces and cities are also catching up. For example, in Shanghai alone, as of August 1980, 1164 electric heating furnaces have been completed with refractory fiber lining renovation with a total power of 33964
