Effect of Incremental Utilization of Unground Sea Sand Ore on the Consolidation and Reduction Behavior of Vanadia–Titania Magnetite Pellets

In the iron and steel industry, improving usage amount of New Zealand sea sand ore as a raw material for ironmaking can reduce production costs enterprises to certain extent. this paper, without any grinding pretreatment was used material, oxidized pellets were prepared by using disc pelletizer, effect on performance green metallurgical properties investigated. The effects compressive strength, falling strength pellets, reduction mainly X-Ray Diffraction (XRD) patterns Scanning Electron Microscope (SEM) analysis methods discuss influence microstructure pellets’ oxidation process. As increased, gradually decreased, increased. When 40%, swelling index 16.31%. increase made suppressed rate decreased. increased degree only 60.06%. experimental results in paper provide specific data large-scale application blast furnace
