Coupling Utilization of Energy and Mass of Hot Metallurgical Slag: a review

In modern society, the demand for energy is increasing day by day. How to get more energy from various channels is related to the future development of human beings. This paper starts with the waste heat recovery of blast furnace slag. Firstly, some common methods of waste heat recovery of blast furnace slag are described, including mechanical crushing method, mechanical mixing method, rotary drum method, rotary drum method, blast method, centrifugal granulation method and rotary disc method. Then, the system of slag waste heat recovery by a compound way is designed.
