223 Practical application of Twin-roll type slag indirect cooling equipment

Abstract

JFE developed a new slag cooling method suitable for molten slag from the ash vitrification process using an electric-resistance furnace. The system consists of twin drum type copper rolls cooled indirectly by coolant flowing inside. Slag is poured between the turning twin rolls and solidified. This paper describes the practical application of Twin-roll type slag indirect cooling equipment. The operating result shows that this method solves the conventional problems of space and water treatment.
