Refractory fiber paste is a kind of all-purpose refractories, which can form many complicated shapes, such as high temperature coating agent. It can be used as a kind of refractory structure by the way of paste. Its formation is a fire-resistant fiber with water and gas and a key at high temperature. At high temperature, a refractory material with hardness and adiabatic property is formed. It is not damp in molten aluminum soup.
