Aluminium Hot Rolling

aluminium indstry process

Non-contact measurement using infra-red sensors has been tried many times but with only limited success on aluminum because of the low and variable emissivity.

AST & 3T companies have successfully developed an infra-red temperature measurement system that uses several different wavelengths and complex algorithms to

accurately measure the temperature in the hot-rolling of aluminum alloys. The AST & 3T pyrometer has the option to store different calibrations in different groups in the

processor memory and it is possible to switch between groups by a signal from an external PLC.

Real-time temperature information during each rolling stage supports process optimization as follows:

Slab temperature:
As the temperature of the slab cannot be directly measured inside the furnace this measurement is the first real temperature measurement.

The slab measurement can be used to adjust the furnace temperature for the next slab but, more importantly, it can be used to set the process parameters in the first rolling operation.

Strip Temperature:

The actual temperature of the strip can be measured at all stages(thickness) and can be used to adjust the rolling speed and cooling intensity according to process requirements.

Coiling Temperature:

Allows the absolute temperature value and the temperature distribution along the strip to be recorded.

This recorded temperature can be used to both modify the previous stage for the next Slab and, most importantly,

to adjust the coiling speed and cooling and thus to obtain the correct conditions for the metallurgical properties.

These metallurgical properties can be achieved either by expensive special aging processes in a furnace or by

adjusting the coiling speed and cooling rate to produce the correct structure followed by natural aging.

Importance of non-contact temperature measurement for Hot Rolling Lines

  • Not possible to touch the metal moving continuously at a high speed during the rolling process with a thermocouple.

  • Even if it is possible to interrupt the rolling process for manual measurement of the slab or thick strip, this cannot be carried out during the final passes and coiling due to the process specification.

  • Even when it is possible to stop the strip, there is a delay in the process and a reduction in the line productivity.
  •      For example, in order to monitor the slab or strip temperature at the start of the process the mill has to be stopped and the thermocouple mechanically positioned.
        At least 10 sec will be needed for the measurement. This results in at least a delay of 20-25 sec.
