slag can effectively granulate the molten converter slag. At the same time, the heat of converter slag can be recovered with air as the medium, so that the converter slag resources can be applied to the maximum extent [4, 5]. The process of air quenching granulation is to use high-pressure air to impact molten converter slag.

the subject [1]. This rst process was based on water granulation of steel-laden slag, followed by separation of the metal-rich and poor (slag) streams. Safety improvements led to the use of air as a granulation medium and the elimination of water. This created a completely dry granulation (atomization) process and novel slag materials with Slag ...
