Aluminum Specific Applications
Temperature is an important parameter for aluminum processing. Whether it is extrusion, rolling, pouring or forging – only precise temperature control secures the required material properties.
To give an example: In the pressing process of extrusion a too high temperature will soften the profile to be formed too much. The product will lose the desired form (production of scrap). Using a too low temperature the aluminum billet will be not soft enough to be pressed through the die without a problem (quality problems, reduced throughput). Additionally, a too hard billet will damage the die.
In many production locations the temperature is only randomly measured using contact thermometers. This method does not allow total and continuous temperature monitoring. In contrast non-contact thermometry is an optimized solution for measurement of molten aluminum, hot finished products and hot machine parts.
Aluminum Applications using Pyrometry
The production process of aluminum extrusion profiles can be controlled using non-contact temperature measurement.
Aluminum Melt / Aluminum Pouring Stream
Pouring streams of aluminum can only be measured with pyrometers using the optical non-contact technology.
The measuring conditions while forging aluminum provide usable and easily repeatable results. For process control, measurements of semi-finished products after preheating and before forming are also possible.
Aluminum Rolling / Cold Rolling
Cold Rolling / Rolling Aluminum is done at very different temperatures - depending on the processing step. Different pyrometers can be used depending on the temperature and the application area.
