ABSTRACT:
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.
