Regarding hot oil versions, a reinforced thermal insulation is included as well as additional heating power and immersed hydraulic brewers. This produces a harder material by either surface hardening or through-hardening varying on the rate at which the material is cooled. Photovoltaic Furnaces & Crystal Growth Equipment. On ECM Technologies’ ICBP installations for low pressure carburizing, oil quenching enhances their advantages: Whatever the suggested installation, ECM Technologies always includes in its offers, depending on customers’ needs, a cold oil quenching solution (80°C max) and a hot oil quenching one (80°C up to 180°C). Réalisation Fx Com'Unik, To get the download link of this document Unfortunately, both new and used motor oil have additives that can release toxins when the hot metal workpiece comes into contact with the oil during the quenching process. To get a grip on why oil is a popular quenchant, it’s important to understand what happens in a quench.The succession of heating and then quickly cooling parts via quenching is a way to achieve added hardness to a part that otherwise wouldn’t have been possible. Quantities are calculated to obtain enough regeneration of oil. Oil quenching is a common method for hardening alloy steel forgings. Quenching is a very easy and simple process relative to the other heat treatment processes. Due to its versatile quenching performance, oil is the most widely used quenching medium, next only to water. Before quenching, you will need to pre-heat the canola oil to a slightly higher temperature than commercial oils. ECM Technologies pays special attention to the manufacturing of its quenching cells, in order to meet with the most demanding expectations. Thanks to the vacuum process and to the quenching cell’s inertia, no flames result from the quench process. This is done by heating the material to a certain temperature, depending on the material. It is ideal for achieving the required strength and hardness properties on many alloys. The process of quenching heat treated metal consists of three stages. When comparing oil quenching cells on traditional furnaces with the ones supplied on ICBP cells, many advantages benefit to ECM Technologies’ solutions: In general, once loads are oil quenched, the next step consists in going through a washing machine to clean the parts before going through the final steps of production. Also, oil quenching allows treating pats made of materials that are not compatible with gas quenching, because of their raw materials’ characteristics. The shortest stage is the boiling stage, which comes after the vapor stage and before the convection stage. Quenching oil serves two primary functions. This also cuts down maintenance costs since this reduces the cell’s cleaning frequency. Quench hardening is a mechanical process in which steel and cast iron alloys are strengthened and hardened. This eliminates the risk of fire. Oil quenching is THE quenching solution for parts that cannot be gas quenched in large quantities because of the wide volume of the loads – this implies poor profitability since it would require several cycles to treat the same amount of parts. The heating causes changes in the crystalline structure of a metal part’s surface; the rapid cooling “freezes” those changes in place and makes the surface harder.The first stage i… Indeed, the oil filling process is optimized and allows compensating wastes … When you oil quench steel forgings, there’s also less risk of cracking compared to water quenching or polymer quenching. This eliminates the risk of fire. CVT (Continuous Variation Transmission) gearboxes’ parts, Poorly alloyed steel gearboxes for automotive applications, All kinds of gearboxes and transmissions for trucks or agricultural applications, All mechanical parts with poor or average added value, Use of cold wall furnaces that are flexible and potentially modular, Strong cost reduction of treatments thanks to reduced gas consumption and to low maintenance costs, Sufficient oil volumes to reduce instantaneous temperature increase when quenching (example: 6.3m, Hydraulic immersed brewers allowing to reach necessary speed for convection to limit calefaction phenomenon (speed in between 0 to 1.4m/s), Variating quenching speed disposal allowing to adapt brewing speed according to parts, and thus, to reduce distortions, Optional oil cell temperature control unit, to respect AMS2750E – set up of a thermowell for SAT thermocouples, Measurement of high and low oil levels with optional alarms when full or empty, A system supported by an exchanger to cool down the oil between two loads (oil/water when cold oil, air/oil when hot oil), Optional automatic oil filling system, including a tank and a filling circuit. Overall, quenching is nothing but a rapid cooling technique where you have to carefully select the quenching … It also has a high flash point which is desired for this process. The material is then often temperedto reduce the brittleness that may increase from the quench hardening process. Oil’s life cycle is highly increased thanks to its non-oxidation. In the initial vapor blanket stage, the hot metal is submerged into the quenching oil. The Process of Heat Treating Oil Quenching. This allows realizing post carburizing cooling cycles for parts requiring machining before quenching, or cooling cycles pre re austenitization for grain refinement before quench. If you continue to use this site we will assume that you are happy with it. Used motor oil is oftentimes free or easy to obtain, but it can contain a few contaminants from being used in a vehicle. Thank you for enterring your email. Thanks to the vacuum process and to the quenching cell’s inertia, no flames result from the quench process. A full immersion in lye meets with most needs. Another interesting fact is that the boiling temperature of the canola oil is noticeably higher than most petroleum oils. Items th… To do so, ECM Technologies implements: Based on the chosen ICBP, maximum gross loads can reach : Copyright © 2018. ICBP Flex & Jumbo: 750kg – optional 1000kg, ECM Technologies maintains its service & maintenance operations despite the ongoing lockdown and in compliance with…, Serthel Industrie, which recently merged with ECM Technologies, offers automated lines for heat treatment and forgi…. Quenching takes a very less amount of time and it is the most effective of performed carefully. Oil’s life cycle is highly increased thanks to its non-oxidation. A brewer is linked to a copper made exchanger to dissipate heat calories. We use cookies to ensure that we give you the best experience on our website. Quenching oil and heat treatment fluids are designed for rapid or controlled cooling of steel or other metals as part of a hardening, tempering or other heat-treating process. These metals consist of ferrous metals and alloys. Indeed, the oil filling process is optimized and allows compensating wastes caused by the treatment of parts. Optional cooling down system to cool down loads using neutral gas (1bar) above the oil pit.
