METHOD FOR PRODUCING NITRIDED FERROVANADIUM Russian patent published in 2012 - IPC C22C33/04 C22C29/16 

Abstract RU 2462525 C1

FIELD: metallurgy.

SUBSTANCE: source alloy of ferrovanadium with the dispersion of less than 0.1 mm is pre-granulated to the size of 0.2-2.0 mm, the combustion process is carried out in a stream of nitrogen or a mixture of nitrogen with an inert gas in the direction of the reaction zone extension. Gaseous nitrogen or a mixture of nitrogen with an inert gas is fed at a rate of 99.6-700.0 mm/s. To increase the nitrogen content in the product it is advisable to enter into the original alloy of 10-20 wt % of the final product. The invention is aimed at reducing the operating pressure in the reactor, which increases the safety of the work to obtain nitrided ferrovanadium.

EFFECT: low strength of obtained briquettes of nitrided ferrovanadium facilitates dosing when entering of ligatures into the steel.
