Estimation of Heat Transfer Coefficient in Squeeze Casting of Wrought Aluminum Alloy 7075 by the Polynomial Curve Fitting Method
Abstract
Numerical simulation is used to improve the productivity and optimize casting process in today’s foundry. The accurate estimation of heat transfer coefficients (HTC) at the metal-mold interface is essential to simulate casting solidification processes. In this work, a 5-step casting mold was employed with section thicknesses of 2, 4, 8, 12, 20 mm. Wrought aluminum alloy 7075 was squeeze cast under an applied pressure of 60MPa in a hydraulic …
