This paper presents a significant method and a basic idea of waste heat recovery from high temperature slags based on Time Temperature Transformation (TTT) curves. Three samples with a fixed CaO/SiO₂ ratio of 1.05 and different levels of Al₂O₃ were designed and isothermal experiments were...

Waste heat recovery from high temperature slags represents the latest potential way to remarkably reduce the energy consumption and CO₂ emissions of the steel industry. The molten slags, in the temperature range of 1723–1923 K, carry large amounts of high quality energy. However, the heat...
