In general, the melt (in the ladle or some other vessel) is placed in an evacuated chamber connected to a vacuum pump, or a ladle filled with molten steel is subjected to a lower pressure by a degassing chamber positioned above it and typically using steam-jet ejectors. Such techniques are only suited to small-scale processes and equipment, and the use of vacuum is usually too exotic to consider.
