Several observations in the iso-fluidity diagrams of blast furnace final slag have shown that liquidus temperature decreased with decreasing MgO content and the viscosity of slag could be regarded as being independent of MgO content in the range of MgO = 5–9%, Al 2 O 3 = 15%, C/S = 1.0–1.2. And, slag fluidity became worse with increasing Al ...
Nov 01, 2018· Foundry slag, obtained by induction, is waste from the ferrous industry whose destination is landfills.
