The magnitude of the air gap at the interface of casting and mould continuously decreases with time.

For the complex geometries of the casting, the calculation is more difficult to obtain the air gap at the interface.

A gap of finite thickness at the interface of mould and metal always increases the heat flux.

A gap of finite thickness at the interface of mould and metal always increases the heat flux?

Conduction mode of heat transfer mainly depends upon the conductivity of the medium and the size of a gap at the interface.

The heat transfer through the interface of metal and mould is always considered as of convection mode.

Surface irregularities of the solidifying casting can increase the temperature at the interface.

Good thermal conductivity of the solidified metal can lower down the surface temperature below than the freezing temperature.

Superheating is the only main consideration for the existence of no contact resistance between the metal and mould.

Perfect wetting only occurs when there is no contact resistance phenomenon in the casting interface.

Which of the following is used for the controlling of heat flow in the casting process?
