METHOD OF OBTAINING BORON ALLOYING ALLOY FOR ALLOYING OF STEEL Russian patent published in 2009 - IPC B22F3/23 C22C35/00 C22C1/05 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy, in particular to obtaining boron alloying alloys for alloying of steel, cast iron, etc. A reaction mixture containing 1-40 wt % of a boron-containing component is prepared: one or several borides of one or several elements selected from a group including calcium, magnesium, aluminium, silicon and 60-99 wt % of the metal component, one or several elements selected from a group including calcium, aluminium, titanium, silicon, vanadium, niobium, zirconium, molybdenum, chromium, manganese, cobalt, iron and/or their alloys. Powders are used with the particles of 3 mm maximum. This is followed by a start of an exothermal reaction of burning in the inert atmosphere.

EFFECT: increased yield output and reduction in the content of the detrimental impurities in the alloy.
