Describe how much heat can be transferred between two
boundary (applied on the surface)
¬ E.g the heat transfer from the casting into the mold during
solidification
¬ Depend on the heat conductivity of the material, temperature
and process
¬ 3 Types of heat transfer coefficient
ˇ Time dependent (cooling channel)
ˇ Temperature dependent (casting and core/mold Gaps
built up while the casting solidification reduces the amount of
the heat transferred into the mold)
ˇ Constant (HTC between top- and bottom mold, mold to core
and continuous cooling channel)
