Steel Slag Recovery For Iron

  • Control of Slag and Insoluble Buildup in Ladles, Melting ...

    Slag Formation: The formation of slag in the melting of ferrous metals in the foundry is inevitable. The composition of slag varies with the type of melting process used and the type of iron or steel being melted. The cleanliness of the metallic charge, often consisting of sand-encrusted gates and risers from Therefore, the basicity of AOD slag is lower than steel slag. Moreover, AOD slag contains much less iron than steel slag. Hence recovery of iron from AOD slag is not important. Perhaps the most important characteristic of AOD slag is that it contains a high amount of Cr (2.5–4.3%) and some Ni (0.2–0.45%).

  • EP2760610A2 - Slag ladle for separation and recovery of ...

    In an implementation, an apparatus for separation and recovery of a molten metal (106) from a slag (108) includes a device (400) attached to a slag ladle (100). The device (400) having a lower edge (404) and free edge (402) is fitted over a part of the slag-ladle (100) holding the molten metal (106) and the slag (108). The device (400) acts as a barrier for the flow of molten iron (106) such ... Iron slag is less dense than the molten iron in the large melters and so floats on top of the iron. This allows the slag to be tapped (poured) from the melter separately. Steel aggregate is produced in the vanadium recovery unit and the oxygen blowing furnace.

  • Recovery of Flake Graphite From Steelmaking Kish

    steelmaking practices is a mixture of graphite, desulfurization slag, and iron that is skimmed from the molten iron feed to the basic oxygen furnace. It is estimated that the graphite content of kish discarded by U.S. steel plants is more than sufficient to meet the total U.S. demand for flake graphite. That need In addition to slag recovery, the liquid furnace slag and ladle slags are generally processed to recover the ferrous metals. This metals recovery operation (using magnetic separator on conveyor and/or crane electromagnet) is important to the steelmaker as the metals can then be reused within the steel plant as blast furnace feed material for ...
