Abstract

PURPOSE:To obtain granulated blast furnace slag having minute structure and uniform quality by granulating molten blast furnace slag flowing downward through a spout and controlling one or more factors out of the viscosity and flow rate of the flowing molten slag, the vol. and press. of a blast stream, and so on so that the slag is scattered over a set distance.
