D. S. MacKenzie, L. Gunsalus, I. Lazerav:
EFFECT OF CONTAMINATION ON THE COOLING RATE OF QUENCH OILS

Proceedings of the 8th Seminar of the International Federation for Heat Treatment and Surface Engineering , IFHTSE 2001, Dubrovnik- Cavtat, Croatia, 12 – 14 September 2001.

ABSTRACT:
Modern quenching oils offer a wide range of capability and performance.  However, contamination of quench oils can markedly effect the performance.  This effect can result in fire, spotty work, cracking, distortion and potentially property or personnel damage.  This paper examines the effect of several common contaminates to the quenching performance of a premium medium speed oil.  Contaminates examined included salt content, water, hydraulic fluid, aging, temperature and soot.  The effect of each of these contaminates on the cooling curve of a medium speed oil was illustrated.
