The method for granulating liquid slag melts, in particular blast furnace slag, in which the melt (2) is ejected into a cooling chamber via a slag tundish (1) and in which fluid under pressure, in particular compressed gas, vapor or pressurized water, is injected in the direction of the slag exit (6) in order to eject said liquid slag, is characterized in that the pressure fluid jet discharges into a throttle pipe (3) which is immersed in the slag bath and whose lower edge is mounted so as to be adjustable in the height direction (4). The corresponding device comprises a lance (7) which is surrounded by a height-adjustable throttle pipe (3) whose lower edge (5) is immersed in the slag bath (2) contained in the tundish (1) and forms a throttling cross section between the slag exit (6) and the slag bath (2). |
