METHOD FOR OBTAINING NITROGEN-CONTAINING ALLOY FOR ALLOYING OF STEEL AND CAST IRON, AND NITROGEN-CONTAINING ALLOY FOR STEEL AND CAST IRON ALLOYING

摘要

FIELD: metallurgy.SUBSTANCE: bearing titanium-chrome ferroalloy is crushed to powder with particle size of less than 0.2 mm. Titanium-chrome ferroalloy contains the following, wt %: chrome - 5.0-35.0, titanium - 15.0-30.0, aluminium - 5.0-10.0, silicon - 5.0-8.0, and iron is the rest. Total amount of Ti, Cr, Si, Al is 30.0-82.0 wt %. Powder is loaded to the container that is moved to a SHS reactor; an exothermic burning reaction is initiated in a layer-by-layer mode at nitrogen pressure of 1.0-15.0 MPa.EFFECT: steady burning reaction with production of ferroalloy with high content of nitrogen uniformly distributed throughout the volume.4 cl, 1 tbl, 1 ex
