A method of melting steel in an oxygen converter from solid metal iron-bearing materials includes the steps of loading these materials and their subsequent heating up to their melting through burning hydrocarbon and solid carbon-containing fuels in an oxygen-containing gas. Then, when the temperature of the melt is 1525.degree.-1580.degree. C. the oxidizing slag is removed from its surface and thereafter a solid iron is loaded into the bath in an amount of 2-5% of the original quantity of the solid metal iron-bearing materials.

Method of melting in an oxygen converter

Steelmaking process

The process according to the present invention relates to the production of ferrovanadium alloys. The process comprises melting a charge containing iron and vanadium with a subsequent reduction of iron and vanadium to give a metal melt. In accordance with the present invention, iron and vanadium are reduced substantially completely. The resulting metal melt is poured into a converter and then purged, through the converter bottom, by means of oxygen blowing at a supply rate of oxygen and for a period of time sufficient to produce a slag containing at least 35% by weight of vanadium pentoxide. Thereafter, the metal melt is discharged from the converter, while vanadium and iron are reduced from the resulting slag by the metallothermal method.
