Abstract

A ferroalloying material is made by reacting a material containing nickel oxide and/or cobalt oxide in intimate contact with a ferroalloy material containing carbon by heating these materials in a confined space under conditions of low absolute pressure to a temperature and for a time sufficient to cause reduction of the oxide and oxidation of the carbon, the oxide of carbon being withdrawn leaving a metallic residue low in carbon containing, in metallic state, the metals of the original mixture. The carbon-containing ferroalloy used may be ferrochromium, ferromanganese, ferrotitanium, ferromolybdenum, ferrotungsten, ferrovanadium, ferrozirconium, ferrohafnium or mixtures or composite alloys of these metals. The reaction may be carried out at a temperature of 1000 DEG -1400 DEG C. under a pressure of about 150 microns of mercury at the end of the reaction period. The ferroalloying material of the invention may contain 20-50 per cent of nickel and/or cobalt, 25-65 per cent of chromium, manganese, titanium, molybdenum, tungsten, vanadium, zirconium and/or hafnium, 0,01-0,15 per cent of carbon, the balance being iron and incidental metallic or oxide constituents in the form of a sintered, porous dense aggregate of fine particles. The material is readily soluble in steel baths for the production of alloy steels.
