The steel industry is a high-energy-consumption and high-pollution industry, which goes against the aims of building a sustainable development and resource-saving society in China. The high-temperature heating furnace is a heart in the industrial development chain of metallurgy, petrochemical industry and the like, and the effect of the high-temperature heating furnace is visible. But it is also a major energy-consuming and pollution-intensive link in industrial development. How to transform or eliminate high-energy-consumption equipment is currently important energy-saving and emission-reducing work, and transformation of a heating furnace is important in the energy-saving and emission-reducing work. The reconstruction and the upgrade of the furnace lining of the heating furnace are necessary links for saving energy and reducing arrangement of the heating furnace. How to realize the lightening of the high-temperature heating furnace becomes the urgent priority of domestic iron and steel enterprises.
