Background
Along with the annual increase of the steel yield in China, the production amount of the steel slag is increased. The steel slag is discarded, so that not only is the waste of metal iron resources caused, but also the environmental pollution is caused. The steel slag is randomly piled up, so that a large amount of land resources are occupied, and the surrounding soil and water systems are damaged.
At present, steel slag is treated by a plurality of methods, such as a hot splashing method, a hot stuffiness method, a water quenching method, an air quenching method, a roller granulation method and the like. The hot splashing method is that high-temperature liquid steel slag is poured into a hot splashing field, is naturally cooled by water or air, and is then crushed; the hot stuffy method is that high temperature liquid steel slag is poured into a hot stuffy pool, and is crushed after the steel slag is cooled by pumping water and continuously stirring; the water quenching method is that high-temperature liquid steel slag is crushed into particles by high-pressure water; the air quenching method is that high-temperature liquid steel slag is cooled and crushed into particles by high-pressure air; the roller method is that high-temperature liquid steel slag is poured into a roller device, and the liquid steel slag is discharged to a slag yard through a plate conveyor after completing water distribution cooling, solidification and crushing in the roller.
