Ceramic fiber products are an excellent refractory. With light weight, high temperature, heat capacity is small, good insulation properties, high temperature insulation performance, non-toxic and so on. Ceramic fiber products are mainly used in processing industry and heat treatment industry (industrial furnaces, heat treatment equipment and other thermal equipment). Processing industry and heat treatment industry, ceramic fiber consumption accounted for 40% of ceramic fiber products, followed by the iron and steel industry, the ceramic fiber consumption accounted for 25% of ceramic fiber products.
