Applications

Aluminium

Billet

The Aluminium Billet Thermometer (ABT) and SPOT AL pyrometer provide fast, accurate temperature measurements for the surface of billets, reducing die wear, improving press efficiency and increasing product consistency.

Die

The SPOT+ R160 thermometer measures the temperature of the die before press loading. This stops hot aluminium solidifying on contact with an under-heated die, causing a significant process stoppage.

Extrusion

The SPOT AL pyrometer uses pre-set, customisable algorithms to make aluminium temperature measurements throughout the extrusion process. Integrates with control systems, it ensures reliability and minimises scrap.
Keep Reading
Quench

The SPOT+ AL pyrometer is suitable for critical quench exit measurements, verifying the cooling rate to ensure the correct hardness and tensile strength is maintained in the alloys.

Reheat / Slab Heat

Before hot rolling, the aluminium slabs must be heated up in the reheat furnace. The SPOT+ AL provides the precision measurement at the furnace exit to ensure correct heating.

Rolling Mill

Aluminium is reduced to the required uniform thickness at the rolling mill, and any necessary surface finish is applied before coiling. Temperature monitoring is essential to optimise the process, and detect potential mill breakdown problems.

Cold Rolling

Cold rolling is performed at a much lower temperature to hot rolling and provides a finished product thickness with an improved surface finish, surface shape and thickness accuracy suitable for the final application.

Preheating and Forging

Before forging, a blank is preheated to temperatures typically around 550 °C (932 °F), depending on the alloy used. It is then worked between flat or shaped dies to produce the desired forged product.

Liquid Aluminium Processing

This is a fast, reliable and efficient heating application which can be used for many purposes, including forging, mounting, coating, or heat treating. It is important to ensure the metal is heated to a certain temperature window, to ensure the desired properties.

Induction Heating

This is a fast, reliable and efficient heating application which can be used for many purposes, including forging, mounting, coating, or heat treating. It is important to ensure the metal is heated to a certain temperature window, to ensure the desired properties.

Mounting / Shrinking

Mounting/shrinking is commonly used in metals applications to fit a component in or around another. It involves heating a part to expand it, then cooling – this requires a fast, accurate temperature measurement to closely control the heating process and prevent overheating that could damage the part.

Preheating for Bending

To make aluminium easier to bend and shape without breaking, it is often heated first. Temperature measurement ensures that the metal is adequately heated to bend easily, while also safeguarding against heat damage to the aluminium or unexpected material thickness.

Preheating for Coating

Heat is often used to apply a surface coating to an aluminium part. If the metal is insufficiently heated, the coating may not correctly adhere to the component, or may not bond in a uniform way. However, if it is too hot, the coating may be damaged. So, accurate temperature monitoring is needed to ensure the heating process is controlled.
