Abstract
The metal casting process is the simplest, most
direct route to a near net shape product, and often
the least expensive. This process in its
fundamental form requires a mold cavity of the
desired shape and molten metal to pour into the
mold cavity. The basic components of a mold
cavity (cope, drag, parting line, riser, spur, pouring
basin, etc.), as well as that part of the molten metal
handling system. The objective of metal casting
has been to produce useful implements for human
consumption as well as beautiful works of art [1].
The heat transfer at the metal mould interface and
magnitude of heat transfer during the early stages
of solidification and the way heat flows across the
mould surface is depend on the interfacial heat
transfer coefficient at metal mould interface and
directly affect the evolution of solidification and
affects the cast ability of metal and quality of
product [5]. I present work the effect of the
difference value of interfacial heat transfer
coefficient is studied for two different alloy
Aluminum alloy (A356), Magnesium alloy
(MgAz91D) for the casting of step disc using
computer simulation [4].
