Abstract

Device for sputtering and granulating liquid slag comprises a spray head with a rotating spinner (9), and a cooling chamber (13) formed as an annular chamber concentrically surrounding the spinner and connected to the spinner. Preferred Features: The tundish outlet is connected with the spinner and the annular chamber via a heated connecting tube (5). Burners (6,7) open into the tube.
