  3. Application Note: Aluminum Hot Rolling Mill – Coiler

This is part 4 of the 4-part Aluminum Hot Rolling Mill application note series – we hope you enjoyed the complete series! Previous parts can be found in our blog feed.

Application Overview:

The temperature at the coiler is an important process parameter. If the temperature is too hot, then the metal may soften and stick. If the temperature is too cool, then the material may become too hard and crack. Hand-held thermocouple probes are notoriously inaccurate and are prone to misuse and interpretation.

Williamson Wavelength Advantage:

The multi-wavelength aluminum infrared temperature sensor produces a much more repeatable and accurate temperature value than the traditional thermocouple. The pyrometer can be used to measure the temperature of the strip as it enters the coiler and/or measure the side of the coil while it is being wound or after it has been removed from the coiler.

Pyrometer Benefits:

  • Assures Desired Mechanical Properties
  • Automates Temperature Measurement
  • Eliminates Thermocouple Maintenance
  • Provides Consistency
  • Measures the Same Spot Each Time

Wavelength Technology:

  • Multi-Wavelength Technology assures accurate readings when viewing the non-greybody aluminum material.

Suggested Models:

  • Pro MW-20-05, 300-900°F / 150-475°C
