Industrial kilns are key equipment for industrial heating, widely used in high-temperature industries of the national economy. Industrial kilns are also major energy consumers, accounting for 25% of the total national energy consumption and about 60% of the total industrial energy consumption. In the energy-saving process of industrial kilns, in addition to heat source transformation, sintering process transformation, combustion process transformation, and kiln structure transformation, the performance of refractory materials and kiln furniture refractory materials used in kilns has a decisive impact on the energy-saving effect of industrial kilns. Industrial refractory insulation materials include refractory fibers, refractory castables, refractory high-temperature insulation coatings (Zhisheng brand), lightweight refractory bricks, A1302 hollow sphere bricks, magnesia bricks, and other refractory insulation materials for kiln lining. The heat consumption in industrial kilns can be basically decomposed into several parts, including the heat absorbed by the product, the heat absorbed by the kiln furniture, the heat carried away by the flue gas, the heat absorbed by the kiln wall and kiln car, and the heat lost by the kiln body. Among them, the heat only used for product absorption is the effective energy. The energy utilization rate in our country is relatively low, with an average thermal efficiency of 30% for industrial kilns, including 5% to 20% for forging kilns and 8% to 25% for heat treatment kilns. The thermal efficiency of continuous heating kilns and tunnel kilns is slightly higher, only 30% to 55%, which is significantly lower than the international average thermal efficiency of over 50% for industrial kilns.

To cope with the severe challenges of the energy situation, energy conservation and consumption reduction in industrial kilns are inevitable trends in development. The energy-saving of industrial kilns is closely related to the technological progress of kiln lining refractory materials, kiln technology design, and construction. The energy-saving effect of kiln lining refractory materials in industrial kilns is achieved through the combination of various kiln lining refractory materials and thermal insulation materials, using integrated lightweight refractory materials as the structural material of the kiln body to reduce heat dissipation and heat storage losses and achieve energy-saving goals. There are multiple ways to combine kiln lining refractory materials with thermal insulation materials. From the perspective of heat transfer, several different thermal conductivity kiln lining refractory material structural combinations are calculated and analyzed, including changes in heat flux density and external surface temperature. In order to optimize industrial furnace lining refractory materials, according to different kiln usage analyses, Zhisheng's ZS-1 refractory high-temperature thermal insulation coating is the best in preventing heat conduction and saving energy.
