ABSTRACT:
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.
