Liquid metal flow behavior during vacuum consumable arc remelting process for titanium

125301-7474 IJET-IJENS @ February 2012 IJENS I J E N S Abstract—To better understand the vacuum arc remelting (VAR) process, a 3D finite element model is established to analyzing the electromagnetic, temperature and flow fields of titanium alloy ingot during steady state melting process using ANSYS software. The research results show that the current flows from the crucible to consumable electr...

Production of titanium tetrachloride (TiCl4) from titanium ores: A review

Titanium (Ti) is the ninth most abundant element on earth. The titanium mineral ores are widely distributed in different parts of the world. The two main ores of titanium include rutile (TiO2) and ilmenite (FeO.TiO2). It is aimed to provide the readers with an insight to the main processes currently employed to extract and recover titanium tetrachloride (TiCl4) from different titanium ores. Due...

Production of Tantalum Powder by Magnesiothermic Reduction of Feed Preform

To develop an effective process for tantalum powder production, a new preform reduction process (PRP) based on the magnesiothermic reduction of feed preform containing tantalum oxide (Ta2O5) was investigated. The feed preformwas fabricated from slurry, which was made by mixing Ta2O5 powder, flux (e.g., CaCl2), and binder. Various compositions of preform in the form of plates were prepared using...
