AIR GRANULATED SLAG PRODUCTION DEVICE, METHOD FOR PRODUCING AIR GRANULATED SLAG, AND AIR GRANULATED SLAG

摘要

PROBLEM TO BE SOLVED: To provide an air granulated slag production device in which the risks of hydration expansion and alkali elution are reduced, and also, handling and storage are facilitated, a method for producing air granulated slag, and the air granulated slag.;SOLUTION: An air flow is jetted to molten slag 3 melted at 1,550°C or higher so as to be granulated, the air granulated slag 7 during scattering after the granulation is collided against a wall face 6 to produce air granulated slag 8 with a flat shape in which the average flattening ratio is 0.6 or higher. In this way, an air granulated slag production device, a method for producing air granulated slag, and the air granulated slag in which the risks of hydration expansion and alkali elution are reduced, and also, handling and storage are facilitated can be provided.;COPYRIGHT: (C)2016,JPO&INPIT
