Abstract

Den foreliggende søknad vedrører en fremgangsmåte for granulering av metallsmelter, hvor en kontinuerlig stråle av flytende metall ved hjelp av minst en gasstrøm oppdeles til metalldråper og gir metalldråpene en fremover- og oppoverrettet kastebevegelse og hvor metalldråpene oppsamles i en nedenforliggende renne med strømmende vann hvori de avkjøles og transporteres til en oppsamlingsanordning. Søknaden vedrører videre en apparatur for granulering av metallsmelter som io utgjøres av et reservoar 1 for smeltet metall med midler for uttømming av en kontinuerlig metallstråle 2 fra reservoaret 1, minst en dyse 3 for å dirigere en gasstrøm mot metallstrålen 2, samt en renne 5 med midler for å tilveiebringe en kontinuerlig vannstrøm i rennen hvilken renne er anordnet på et lavere nivå enn gassdysen eller gassdysene 3.The present application relates to a method for granulating molten metal, in which a continuous jet of liquid metal is divided into metal droplets by means of at least one gas stream and gives the metal droplets a forward and upward throwing movement and in which the metal droplets are collected in a chute with flowing water. and transported to a collection device. The application further relates to an apparatus for granulating metal melts which consists of a reservoir 1 for molten metal with means for discharging a continuous metal jet 2 from the reservoir 1, at least one nozzle 3 for directing a gas stream towards the metal jet 2, and a chute 5 with means for providing a continuous flow of water in the gutter, which gutter is arranged at a lower level than the gas nozzle or gas nozzles 3.
