While both of the petroleum quench oils Microtemp 157 (T 157) and Microtemp 153B (T 153B) exhibited full-film boiling, this was typically not observed for any of the vegetable oils evaluated in this study. [4] Higher cooling rates were observed for rapeseed oil compared to petroleum oil, which was attributed to the relatively poor stability of the vapor blanket formed by the rapeseed oil. Tech Talk on Quenching Oils. You are being redirected because this document is part of your ASTM Compass® subscription. Quench hardening is a mechanical process in which steel and cast iron alloys are strengthened and hardened. Quenching Oil 32 Parks AAA Alternative is a widely used quench oil for 01 Tool Steel. By closing this message or continuing to use our site, you agree to the use of cookies. Lavender oil is one of the most popular essential oils - and for good reason! Different quenching media have different degrees of severity. Sleep Music for Quarantine 24/7, Lucid Dreams, Sleeping Music, Meditation, Study Music, Sleep Yellow Brick Cinema - Relaxing Music 3,474 watching Live now Quenching in oil has a reduced cooling rate compared to water (or brine) which also helps to keep distortion at bay. The performance objective is to reduce the linolenic and linoleic ester content of the vegetable oil to increase the oxidative stability, making the resulting vegetable oil more suitable for use in industrial oil applications. 1.     Quenching Oil 50 (Parks 50 Equivalent) Benefits. In addition, advances in quenching, such as new oil and polymer quenchants, alternative quench methods (gas quenching, nduction i hardening) will be discussed. 3.     [26] In this test, the fluid viscosity increase with time is monitored, and increasing viscosity indicates increasing instability. Hardening steel with motor oil is a way of performing what is called the case hardening of steel. [12] Przylecka and Gestwa have reported the use of an unidentified vegetable-oil-based quenchant for hardening carburized steels. [22,23] The maximum heat-transfer coefficients exhibited by the vegetable oils in this study decreased as follows:   [13]     Has additive manufacturing had any impact on your business? However, Wu reported that epoxidization of rapeseed oil exhibited greater oxidative stability than rapeseed oil without chemical modification, and the biodegradability was not affected. Soluble oil fluids form an emulsion when mixed with water. Natural soybean and sunflower oils, as well as commercial mineral quenching oil, were chosen for investigation. However, even SO2 and SO3 did not exhibit the excellent oxidative stability shown by both petroleum-oil-based quenchants Microtemp 157 and Microtemp 153B. Fig. A brief comparison of the quenching performance exhibited by vegetable oils relative to petroleum oil will be illustrated. Petroleum-based mineral oil is a commonly used quenching media for heat treatment, due to its moderate cooling rate which provides minimum distortion to components. [31] Genetic engineering has produced soybean oil with >85% oleic acid ester contents.     Quenching Oil 50 (Parks 50 Alternative) Benefits     Figure 1 shows that soybean oil (typical of other commonly available vegetable oils) does not exhibit the same film-boiling or nucleate-boiling behavior as exhibited by petroleum-oil quenchants. [7, 8]     Very popular with knife makers. Transformer oil (also known as insulating oil) is a special type of oil which has excellent electrical insulating properties and is stable at high temperatures. [6] Quenching performance of the ethyl esters were also equivalent to each other and exhibited greater quench severity than the vegetable oils. Food Grade Quenching Oils. Although soybean oil is of particular interest as a potential basestock for quenchant formulations, it has been shown previously to be one of the oxidatively unstable vegetable oils that might be selected for this purpose. It provides superior service where a moderate rate of quench is … Transformer oil is used in oil-filled electrical power transformers to insulate , stop arcing and corona discharge , and to dissipate the heat of the transformer (i.e. sunflower > corn > soybean > canola  > cottonseed       If we are using oil as an arc-quenching medium we have to consider advantage of oil so followings are advantages of oil as an arc-quenching medium. For more information: Contact George E. Totten, Portland State University, G.E. When a knowledgeable client asks what the quench oil is, using the proper commercial quenchant might mean the difference between a sale or not. With the development of new alloys for coatings, it is even more important than ever to understand how something as generic as sample preparation can affect the evaluation of a coating. New advances in modeling quenchant flow using computational fluid dynamics and modeling distortion, as function of quenchants and heat transfer will also be discussed. However, quenching oil is also associated with several environmental liabilities such as oil fumes, fire hazard, oil spills, leaking underground storage tanks, and waste oil disposal liabilities.
