Production of tool steels using chemically prepared V2O3 as a vanadium additive |
摘要 |
Process for producing tool steel wherein a vandadium additive consisting essentially of chemically prepared, substantially pure V2O3 is added to a molten steel having a carbon content above about 0.35 wt. % and containing silicon in an amount of from about 0.15 to about 3.0 wt. % and wherein a slag covering the molten steel contains CaO and SiO2 in a weight ratio (CaO/SiO2) which is equal to or greater than unity.
