From the thermal point of view, the insulation ceramic fiber also has good high temperature performance. Because the main mineral composition of kaolin clay used to produce the insulation ceramic fiber is kaolinite (Al2O3·2SiO2·2H2O). And kaolin has a higher degree of refractoriness than clay, and its refractory temperature is closely related to its chemical composition.
Due to the characteristics of the insulation ceramic fiber, using it to transform the industrial furnace can greatly reduce heat storage capacity of furnace body and heat dissipation through furnace body. Thereby it can greatly improve the thermal efficiency of the furnace and improve the heating capacity and production efficiency of the furnace. In turn, the heating cycle time is shortened, the oxidation and decarburization of the workpiece are reduced, and the heating quality is improved. After the application of insulation ceramic fiber lining on the gas-fired heat treatment furnace, the energy-saving effect is 30~50% respectively, and the production efficiency is increased by 18~35%.
Due to the use of insulation ceramic fiber as the lining, the heat dissipation from the furnace wall to the outside is significantly reduced, and the average surface temperature of the furnace wall is reduced from 115 ° C to 50 ° C. The combustion and radiation heat transfer inside furnace is enhanced, and the heating rate is accelerated, thereby improving the thermal efficiency. Reduces energy consumption and increases productivity. Moreover, under the same production conditions and thermal conditions, the furnace wall can be made thin, thereby reducing the weight of the furnace and making repair and maintenance of furnace easier.
