Abstract
Ferrovanadium carbide addition agents comprising 75 to 85% vanadium, 8 to 12% carbon, 8 to 12% iron, less than 2% oxygen and having a density of from about 5.8 to about 6.2. The addition agents are produced by fusing vanadium oxide, iron and carbon at about 1700.degree. C. to about 2100.degree. C.
Claims3
A ferrovanadium carbide addition agent comprising 75 to 85% vanadium, 8 to 12% carbon, 8 to 12% iron, less than 2% oxygen and having a density of from about 5.8 to about 6.2.
A process for preparing ferrovanadium carbide addition agents having a density of from about 5.8 to 6.2 comprising mixing and combining (a) vanadium oxide, (b) iron and (c) carbon, fusing the combined material at about 1700.degree. C. to about 2100.degree. C. at atmospheric pressure under a reducing atmosphere, the proportional relationship between (a), (b) and (c) being such that the ferrovanadium carbide addition agent recovered comprises 75 to 85% vanadium, 8 to 12% carbon, 8 to 12% iron and less than 2% oxygen.
