ABSTRACT:
The quench severity of a molten salt bath is drammatically increased by adding substantial amounts of water to the bath while it is being vigorously agitated by two impellors submerged in the bath. One impellor causes an upward flow and the other a downward flow of molten salt which results in a quiescent condition at the surface of the quench zone of the bath.
