Study on Sintering Characteristics of Ultra-Poor Vanadium

Artificial rich ore for blast furnace use can be produced by sintering ultra-poor vanadium-titanium magnetite (PVTM) with a high-grade iron concentrate. Here, acid (R = 0.33, 0.50), self-fluxing (R = 1.10), and high-basicity (R = 2.60) PVTM sinters were produced in a sinter pot. Their performances were determined using the comprehensive Artificial rich ore for blast furnace use can be produced by sintering ultra-poor vanadium-titanium magnetite (PVTM) with a high-grade iron concentrate.

Metals Free Full-Text Electrodeposition of Aluminium-Vanadium

The Al-V alloys were synthetized by potentiostatic electrodeposition onto a glassy carbon electrode from equimolar AlCl3 + NaCl bath containing vanadium ions at 200 °C. The alloy deposits were characterized by X-ray diffraction, scanning electron microscopy, and energy dispersive spectroscopy. The deposits were identified as Al3V OY furnace, an improvement of COREX, is the vigorously developed environmentally friendly iron-making process. However, it has a higher fuel ratio than blast furnace. The high prereduction degree (PRD) of direct reduction iron (DRI) is beneficial to decrease the fuel consumption of OY furnace but also affect the softening, melting, and Smelting Vanadium–Titanium Magnetite by OY Furnace: Effect of
