Aluminosilicate refractory fiber is a new type of fire-resistant insulation material. Statistics show that the use of aluminum silicate refractory fiber as resistance furnace refractory or insulation material can save energy consumption by more than 20%, and some up to 40%. Because the aluminum silicate refractory fiber has the characteristics of high temperature resistance, good chemical stability, and low thermal conductivity, the use of aluminum silicate refractory fiber as the lining of the resistance furnace in the non-ferrous metal casting workshop can shorten the heating time and reduce the wall temperature and energy consumption. .
