Application areas using Temperature Chart Recorders to record the temperature during the metal heat treatment process to maintain quality control historical data records:
Normalising
Normalising involves heating the steel to about 40°C above its upper critical limit. The steel is then held at this temperature for a period of time and is then cooled in air. It is desirable that the temperature of the steel shall be maintained for a time period more than 2 minutes per mm of section thickness and shall not exceed the upper critical temperature by more than 50°C.
Full Annealing
Steel is heated about 25°C above the upper critical temperature, held for a set time and then cooled slowly in the furnace.
Hardening
Hardening involves heating a steel to its normalising temperature and cooling (Quenching ) rapidly in a suitable fluid e.g. oil, water or air.
Stress Relieving
This process involves heating the metal to a temperature in the range 550°C to 650°C and held at this temperature before being cooled at a controlled rate.
Spheroidising
The process involves heating the metal to between 600°C and 650°C
and holding it at at the selected temperature for a period of time.
Tempering
Tempering is the process of reheating steel.
