Background
The metallurgical waste residue refers to various solid wastes generated in the production process of the metallurgical industry. Mainly blast furnace slag generated in an iron-making furnace; steel slag; various non-ferrous metal slag produced by non-ferrous metal smelting, such as copper slag, lead slag, zinc slag, nickel slag and the like; and red mud discharged from alumina extraction from bauxite and a small amount of iron oxide slag generated in a steel rolling process. The utilization rate of the blast furnace slag in China is up to more than 85 percent. In order to adapt to different purposes, the blast furnace slag can be respectively processed into several main products such as water granulated slag, slag crushed stone, expanded slag and the like. However, before the blast furnace slag is processed into water granulated slag, slag crushed stone, expanded slag and the like, a large amount of heat is carried after the blast furnace slag is discharged from the furnace. It is estimated that the temperature of the high-temperature waste slag discharged in the steel smelting process is about 1000-1600 ℃, and high heat energy is stored, and the heat energy is totally dissipated into the atmosphere by cooling the high-temperature waste slag in a natural cooling or water spraying manner, so that the energy is seriously wasted.
