The heat treatment process of cast aluminum
is composed of three stages: heating, heat preservation and cooling. The whole
process can be described by several parameters, such as heating speed, heating
temperature, heat preservation time, cooling speed and heat treatment period.
In each heat treatment process specification, temperature is very important. If
the temperature measurement is not accurate, the heat treatment process
specification can not be correctly implemented, which will cause the quality of
aluminum castings to...
