Method for production of granules

摘要

A method for granulating a stream of molten metal which is caused to fall from a launder or the like down into a liquid cooling bath in a tank. The metal stream is divided into droplets in the liquid cooling bath, which solidify and form solid granules. A substantially uniform flow of cooling liquid is caused to flow from one of the side walls in the tank substantially perpendicularly against the falling metal stream, said flow of cooling liquid having a velocity of less than 0.1 m/second. The distance from the outlet of the launder to the surface of the liquid cooling bath is kept less than 100 times the diameter of the metal stream measured as the metal stream leaves the launder.
