Title:
A slag Pelletization system and the operation method
Document Type and Number:
Japanese Patent JP6001178
Kind Code:
B2
Abstract:
A slag granulator device comprises a chamber, a rotary atomising granulator 5 mounted in the chamber for atomising molten slag 9 and an air supply for supplying air to the molten slag 9 before it is atomised. Figure 3b shows a device where slag 9 is fed onto the rotary granulator 5 through a pipe 4 from a tundish 2, with air being supplied through a porous section 31 of the pipe 4 at an end remote from the tundish. Figure 4b shows a device where air is supplied through a lance 32 located in a pipe which feeds slag 9 from a tundish 2 onto the rotary granulator 5. This device further comprises a slag flow stopper 17. Figures 5a and 5d respectively show devices where air is supplied through a porous plug 35 located across the entire top surface of the rotary granulator 5 and through a porous plug 37 located in the centre of the rotary granulator. In the last two devices air is supplied through a drive shaft 6 to the porous plugs 35 & 37. The rate of air supply is controlled according to slag granule size.
