Resumo
One of the primary purposes of any quenchant is to mediate heat transfer and enhance the surface uniformity throughout the quenching process. For polymer quenchants, this is achieved by the formation and subsequent breakage and removal of an insulating film surrounding the hot metal part upon initial immersion. To provide process control, it is necessary to minimize any changes in the uniformity of the heat transfer process caused by variation in polymer concentration, quenchant contamination, and polymer degradation. Therefore, an essential component of any well-run quenching operation is periodic monitoring of the quench bath. In this paper, procedures using inexpensive and easy to use equipment for maintaining a polymer quench bath will be discussed.
