Abstract
Stainless steelmaking produces different types of slags which need to be cooled, stored, and pretreated before further use. In current practice, the slag is cooled in an air atmosphere, but water cooling has been envisaged to speed up cooling. The aim of this article is to simulate the cooling of argon‐oxygen decarburization (AOD) slag under the conditions of ambient cooling and water cooling. The effects of the thickness and initial temperature of the slag layer are also studied. Finally, practical means to improve the cooling practice are evaluated based on the model predictions.
