Production of Ferromolybdenum from Mill Scale via Aluminothermic Process

Öz

In this study, the production of ferromolybdenum (FeMo), which is an iron-based alloy, was carried out through the metallothermic reaction. This method was chosen due to its low cost, short process time and minimum energy need. Before the experiments, FactSage and HSC software were used for thermochemical modeling. Mill scale was used as a starting material in the experimental studies. Mill scale is waste material and it contains 70% iron by mass. MoO3 was used as the molybdenum source and aluminum was used as the reducing agent. Produced samples were characterized by Atomic Adsorption Spectrometry (AAS), X-Ray Fluorescence (XRF) and hardness tests (micro-Vickers). Initially, the effect of aluminum stoichiometry, which was used as a reductant, on FeMo efficiency was investigated. The closest result to the target alloy was achieved with the sample having 105% aluminum stoichiometry. Fe and Mo efficiencies were 95.16% and 97.21%, respectively. The effects of weight change on Fe and Mo efficiencies were investigated by using samples having 105% aluminum stoichiometry. It was observed that the closest result to the target alloy was achieved with a 75 g charge. Fe and Mo efficiencies were 99.10% and 97.98%, respectively. These were the highest efficiency values obtained in all experiments. The hardness values of samples were between 678 HV10 and 767 HV10. The highest hardness value was obtained in the alloy containing 100% stoichiometric aluminum. It was concluded that there was no significant difference in the hardness values of the samples due to the similarity in their chemical structures.
