Blast Furnace IronmakingA View on Future Developments
Jan 01 2017 · Dry slag granulation is based on molten slag atomisation using a variable speed rotating cup or dish (see Figure.4). The slag is delivered on to the centre of the cup from a slag runner via a vertical refractory lined pipe. The rotation of the cup forces the slag outwards to the cup lip where it is atomised (see Figure. 5).
