MF 1826 Properties and Uses of Iron and Steel Slag

+

The blast furnace is the primary means for reducing iron oxides to molten, metallic iron. It is continuously charged with iron oxide sources (ores, pellets, sinter, etc.), flux stone (limestone and dolomite), and fuel (coke). Molten iron collects in the bottom of the furnace and the liquid slag floats on it.

May 09, 2018· The iron ore is reduced to iron in that temperature and all other materials form a slag and floats on the top of iron. This slag is periodically tapped off as a molten liquid and then rapidly quenched with large volumes of water. This process optimizes the cementitious properties and produces granules like coarse sand. This granulated slag is then dried and ground to a fine powder.
