Abstract：The BF slag is nearly 50% of the gross solid waste in steel industry. The BF slag is a silicate material of many applications. The BF slag is used as raw material for cement industry after treatment, with saving of 45% limestone, 50% energy consumption and reduction of 44% CO2 emission. Traditionally, the BF slag is granulated in water with air pollution,water pollution and the heat loss etc. A new method—dry granulation of BF slag could save fresh water, but also recycle the heat of slag. It can also be used in cement industry as the BF slag traditionally treated with water.
