A solar reflector soiling study was carried out at a ferromanganese smelter in South Africa to assess the rates different locations around plant. Several meteorological parameters were monitored give insight into conditions that lead increased soiling. Mineralogical characterization of dust samples collected from reflectors and atmosphere revealed only certain size fraction is importance with r...

Adding high carbon ferromanganese in the early decarburization stage of 200 series stainless steel can reduce electrolytic manganese added during alloying; however, oxidation loss is severe. This paper studies CO2 and O2 mixed blowing thermodynamics kinetics on retention steel. The thermodynamic study indicates that reduces when used instead part molten decarburization. Meanwhile, kinetic deter...
