Summary: Quenching systems for induction hardening may utilize various agitation modes including: conventional immersion quenching, open spray and submerged spray processes. These are not equivalent processes and proper engineering dictates that they be appropriately addressed. In this paper, an overview of basic design consideration of these different agitation systems, as they apply to induction hardening systems, will be provided. Examples will also be provided illustrating the practical application of these basic principles.
