Main raw materials of high alumina refractory fiber
With industrial alumina and high purity silica as the main raw material, the mixture is made in a certain proportion and then mixed evenly. After light burning, it is melted by electric arc furnace or after mixing by dry method. The melt flow is made by centrifugation or compressed air injection, and the raw cotton of high alumina refractory fiber is made. Cotton can be used directly, but also can be further processed into a variety of refractory products such as plate, blanket, blanket..
