steelmaking slag iron magnetic field intensity

Steelmaking Slag an overview ScienceDirect Topics

Apr 04, 2012· Ironmaking and steelmaking slags are inevitably generated as a by-product from ironmaking and steelmaking processes. Main components of the slags are CaO, SiO 2, Al 2 O 3, MgO, and iron oxides, and the compositions of slags depend on the process.In the case of Japan, three types of slags, namely BF slag, BOF slag, and EAF slag are mainly produced, which amount is shown in
