Abstract

A method and system for processing molten slag is characterized in that molten slag is first spread onto a slag receiving means which is substantially made of a steel plate of desired thickness and is tiltably mounted on the floor of a roofed slag processing factory and is subsequently air and water-cooled such that the slag is solidified and finally is water-quenched in a cooling water pit whereby the resulting solidified slag is of practical use which neither collapses nor produces dust.
