Abstract:
Carbothermic reduction of fine steel sludge (FSS-LD) and coarse steel sludge (CSS-LD) occured from Linz Donawitz steelworks in a Brazilian semi-integrated steel plant. These processes were carried out prior to characterization, for which, they determined high levels of iron content (51.54 - 77.53%) and zinc content (0.49 - 1.69%), as well as, a little specific carbon content (0.0215 - 0.0350%). Morphology shown by these residues are made up of globular aggregates of metallic iron intergrown with crystals of iron oxides and zinc oxide with particle sizes between 0.12- and 0.15-mm observable through a Scanning Electron Microscope (SEM). Thermal characterization via DTG-DSC-TG at 1000°C prior to carbothermic reduction Mass losses of 92.57% were observed for the FSS - LD sample and 97.43% for the CSS - LD sample
