Özet

Sanitary tapware faucet that can drain hot and cold water from the plumbing systems in the desired proportions by mixing are called faucets. The raw material of faucets used today is generally brass alloy (CuZn39Pb1Al-C) and their production is carried out through the method of low-pressure die casting. In this study, K type thermocouple was placed in such a way that there was a distance of 3 mm to the casting surface of the mould, and temperature changes during the production were obtained by the measurement and recording device. Interfacial heat transfer coefficient was calculated numerically in Ansys Fluent program with the combination created by 1,283, 1,263, 1,243, 1,223, 1,203, 1,183, 1,163 K values of casting temperature and mould temperatures of 413, 473, 533, 593, 653 K. Numerically calculated heat transfer coefficients are entered by creating casting simulation in the Magma program, and they were analysed by making comparison between experimental temperature curves and simulation temperature curves.
