Steelmaking slag deriving from BOF process (using the Linz-Donawitz (LD) converter) comes from the pig iron refining process, wh ich converts molten pig iron and steel scraps into high quality steel. Most slags from steel pl ant derive from this pr ocess, with an average of 150-200 kg of slag generated per tonne of st eel produced.

The coated LD slag particles were examined and the FE-SEM images were captured on both photomicrographs and digital files. The accelerating voltage of the instrument was fixed at 5 kV for BSP LD slag, 3 kV for RSP LD slag and 4 kV for TSP LD slag. The LD slag samples were examined at the magnification of X18.59, X33.90 and X24.95.

02-06-2017· Basic oxygen furnace slag (BOF slag) is an unavoidable by-product of steelmaking process of basic oxygen furnace. The main chemical constituents of BOF slag are CaO, FeO, Al 2 O 3 , SiO 2 and MgO. Due to its high metallic value (FeO: 16-20%) and lime content (CaO: 45-50%), it is possible to use in iron making and steelmaking process to replace lime and recover iron and CaO.
