  • Blast furnace slag granulation | Climate Technology Centre .

    The molten slag is then separated from the liquid metal and cooled (Gielen et al., 2008). If the molten slag is cooled and solidified by rapid water quenching to a glassy state, little or no crystallization occurs. This process results in the formation of sand size (or frit-like) fragments, usually with some friable clinkerlike material.
