Using refractory fiber products in kilns for energy saving 3

     2. Disadvantage and prospect of refractory fiber products 

     Although refractory fiber products play an important role in thermal insulation and refractory in the high-temperature industrial field, there are also significant disadvantages, especially its inhalability which will bring certain harm to the environment and human body. Some foreign companies have strengthened their restriction on using of amorphous refractory fiber products. At present, a biosoluble amorphous refractory fiber product appears in the market of thermal insulation refractory materials. This super fiber (SiO2-CaO-MgO refractory fiber product) is a pollution-free and environmentally friendly material. The future production trend of refractory fiber products is pollution-free, refined and multifunctional. The production of high tech functional fine ceramic fibers, which is processed with new raw materials and new technologies and has high added value, will be increasing. It is of great significance for optimizing thermal insulation refractories.
