Abstract :

Heat treatment is the process used for the alteration of physical properties of the material under treatment for their suitability of structural and functional requirement. The thermal simulation of the heat treating process is usually a transient type of temperature analysis, in which the hot metal part temperature changes with respect to time from an initial state to a final state. In the simulation, initial temperature of the hot part and temperature of quenchant are usually easy to obtain and can be assigned with reasonably accurate values. So are the thermo physical properties of the part material. The critical part is to determine the heat transfer coefficient between the hot part and quenchant. In liquid quenching, the heat transfer between hot metal parts and water is very complicated and it is difficult to determine the HTC. For this experimentation the EN 9 steel rod with Φ50 mm and length 100 mm along with water and ethylene glycol mixture with different concentrations as quenching medium are used. More and more attention is paid to numerical modelling using finite element packages and computational fluid dynamic packages for the benefits on money and time saving. A part model is created in 3-D form, then the model is meshed and by applying the actual boundary conditions the CFD analysis is conducted. In order to validate CFD analysis the experimental trials are conducted. In this paper the conducted experimental trials are discussed and compared with the CFD results. Keywords— Quenching, HTC, CFD, heat flux, cracking, and temperature gradient.
