A non-water cooled, nozzle-mixed oxy-fuel burner wherein high oxidant velocity and a venturi aspirate or recycle products of combustion through the burner block and mix them into the flowing oxidant stream to act as a diluent and provide mass to moderate flame temperature. The burner includes means in said oxidant stream to improve flame stability.

An air cooled refractory covered injection lance for introducing reactive gases below the surface of a molten metal bath where the lance is provided with means to surround the reactive gas conduit with a high velocity cooling fluid to prevent thermal decomposition of the reactive gas prior to its injection into the molten metal bath.

The present invention is a process for the removal of hydrogen from molten ferrous alloys in the unkilled state via a chemical reaction with a halogen-containing compound. The halogen-containing compound is typically introduced into the molten alloy in the gaseous state. The process can be carried out in a conventional ladle metallurgy station.
