By electromelting coal gangue, coke gem, alumina, silica, zirconia and other raw materials, the fiber is made by spinning process. After needling and heat treatment, the fiber is interwoven evenly, high tensile strength, and does not contain any bonding agent. The product has good resistance to chemical erosion and can be widely used in thefields offire resistance, heat insulation and heat preservation.
