The invention provides a method of melting and superheating ferrous material comprising the steps of charging a vessel with ferrous material and injecting into the vessel coal and oxygen in such ratios as to combust the coal to provide adequate heat for the melting of the ferrous material and to provide residual carbon in the melt to superheat the melt upon oxidation of the carbon.

Melting of metals

The invention provides a process for refining steel comprising the steps of blowing a refining gas at the upper surface of the melt contained in a refining vessel by means of an overhead lance; injecting a stirring or processing gas directly into the vessel below the surface level of the melt therein; and introducing carbon from above onto or through the upper surface of the melt in the refining vessel.
