Air-cooled blast furnace slag (ABS)

The molten slag and iron collect at the 'hearth' at the bottom of the furnace. The iron and slag are 'tapped' (removed) together at regular intervals, held in a trough to allow separation, then the slag is allowed to run into open air pits where it cools in layers. The cooling is facilitated by water spraying which causes the slag to crystallise and crack, aiding excavation from the pit. The ...
