Compare Between the Results of the Casting Simulation and the Results of Experimental Production with Calculating the Interface Heat Transfer Coefficient of the Casting-Mold

Abstract

Sanitary tapware that can drain hot and cold water from the plumbing systems in the desired proportions bymixing are called faucet. The production of faucets used today is conducted by using a low-pressure castingmethod. The raw material of the body, which is the main part of faucets, is generally brass alloy(CuZn39Pb1Al-C). The material of faucet molds produced using the casting method is the copper-berylliumalloy (CuCoNiBe). Some casting defects can be raised of used in these different two alloy materials. Thesedefects should be solved before the production phase. Therefore, to be studied to detect these defects indesign phase. Although the literature was researched, any study could not be found about the faucetproducts. Besides this study will be led the faucet field due to missing studies for the faucet products. In thisresearch, K type thermocouples were placed into the mold in such a way that there was a distance of 3 mmto the casting surface, and temperature changes during the production were achieved by the measurementand recording device. 1283,1263,1243,1223,1203,1183,1163 K values of casting temperatures that wereidentified as critical in Ansys Fluent program and interfacial heat transfer coefficient of the combinationscreated by casting temperatures of 413,473,533,593,653 K were calculated numerically. Casting simulationwas created in Magma program by using calculated IHTC values, and they were analysed by making acomparison between experimental and simulation temperature curves. The match of the defects wascontrolled by comparing the defect results of simulation in which convergence within temperature curveswere provided and the defects of scrap parts in experimental production.
