Effect of V2O5 on Consolidation, Reduction, and Softening-Melting Behavior of High-Cr Vanadium Titanomagnetite

Vanadium titanomagnetite is an important mineral resource. It a raw material for ironmaking, vanadium extraction, strategic metal titanium production, and dioxide production. In this study, high chromium (High-Cr VTM) ordinary iron ore were used as materials pelletizing. The effect of V2O5 on the preparation properties High-Cr VTM pellets was studied. influence green pellets, compressive strength oxidized reduction swelling index degree, softening-melting behavior, migration law Fe, Ti, Cr in process studied by X-ray diffraction (XRD) scanning electron microscopy (SEM). results show that with increase content, basically showed trend first decreasing then increasing but all met basic requirements When added amount pellet 6%, lowest at only 2565 N/pellet it still quality blast furnace As dosage increased, degree decreasing. addition can softening initial temperature, final melting start dripping temperature narrowing interval, expanding interval. experimental provided data reference revealing during smelting process.
