With the rapid development of science and technology, the field of industry has been greatly improved. In today's increasingly fierce industrial development, the concept of green environmental protection and other energy saving has gradually penetrated into the industry production. At present, whether at home or abroad, the effect of energy saving and emission reduction in the metallurgical industry has increased the degree of concern. A large amount of energy is consumed in the production process of iron and steel metallurgy, and a large amount of heat is released in the production process. The secondary utilization of waste heat can bring good economic benefits to enterprises and also greatly help the energy conservation and emission reduction of the iron and steel metallurgy industry.
