The impeller forces the oil down the small tank and into the bottom of the quench tank. QUENCH SYSTEMS for Oil or Water. Figure 6. For example, water may be introduced into the quench oil through a leak in the heat exchanger. I am very fussy about oil temp at quench time. I have to mention, that I am self learning and really don't know what I'm doing, so if this is a bad idea let me know. Oil oxidation may also be monitored and detected by infrared spectroscopy. This is accomplished with quench bath maintenance procedures. For a better experience, please enable JavaScript in your browser before proceeding. As previously discussed, a quench oil’s quenching performance is dependent on its viscosity. You may also choose an optional immersion heater (recommended) and a perforated steel work basket. valve cover off a v-8 works good.

The best thing to re purpose into a quench tank is an old electric roster oven. This forces the flow upward and the oil returns to the pump tank from the top cross pipe. Traces of low-boiling contaminants may concentrate in the vapor phase resulting in a relatively low value. Water, because it is not compatible with oil and possesses different physical properties such as viscosity and boiling point, will cause increases in thermal gradients. I actually feel like I've lost 10 I.Q. Experimental procedures, such as Conradson carbon number, hot-panel coker test and the rotary pressure vessel oxidation test (RPVOT) may also be used. Then place a few at a time into my oil, to bring its temp up. Effect of Quench Oil Oxidation on Cooling Rates. When conducting the open-cup flash point, the relatively low boiling by-products are lost during heating and have less impact on the final value. Sentry Quench Systems are designed to ensure optimum conditions for tool heat-treating applications. Chemical analysis can identify and measure these by-products. Figure 6 illustrates the effect of varying amounts of water on cooling a nonaccelerated quench oil. Water from oil contamination or degradation may cause soft spots, uneven hardness, staining, and worst of all, fires. i like a horizontal quench tank for blades. (1993). When the oil hits 120 degrees you are ready to go. A timer is activated as the glowing nickel ball passes a photoelectric sensor. Viscosity of a Martempering Oil as a Function of Time. The most common laboratory tests for water contamination are either Karl Fischer analysis (ASTM D6304) or distillation (ASTM D95). It has plentiful volume for all but sword work. Commercial oil quenching tanks have water cooled heat exchanges to keep the oil temperature under control. Saving up for some parks 50, but it seems to do fine with the 1084 I'm working with. Quench oil characterization is readily performed by measuring a series of physical properties including: viscosity, water content, neutralization number, precipitation number and flash point (Table 1). I don't do swords so there's no need for a tall tank like you see in most of the videos.
