Vanadium as a metal vitamin owns excellent physical and chemical properties widely supplied in the areas of aerospace, steel, chemical engineering, nuclear industry and etc. Vanadium is one of the most strategically important rare metals in the world. V has advantages of low neutron irradiation activity, high thermal conductivity, low coefficient of thermal expansion, anti-irradiation swelling.
By electron beam melting and continuous electrochemical polishing techniques, high-pure vanadium wire is processed and vanadium wire has good mechanical properties, surface finish. Impurities contained in the vanadium will be decreased. Additionally, mechanical properties and processability are enhanced, too. So final finished V wire is high purity, uniform structure, and bright surface.
Powder metallurgy technique, process steps are
Pre-treatment vanadium powder→Compress moulding→Vacuum sintering→Electron beam melting→Forge→Rotary forging→Drawing→electrolytic cleaning→heat treatment
