This is part 1 of a 4-part application note that covers the Aluminum Hot Rolling Mill – stay tuned for more posts.

Application Overview:

Before heading to the rolling stands, a large ingot of aluminum is heated in a furnace for hours to days. Ingots need to be heated for this long of a time so they are completely heated through to the core so that the ingot can be rolled out into a longer strip without being reheated.

Williamson Wavelength Advantage:

The ingot is soaked for such a long time to assure uniform temperature prior to rolling, and the soaking time is often extended due to process down time. These extended soaking times often alter the emissive character of the aluminum even when the surface texture is reasonably consistent, and this is the primary reason why the Dynamic ESP Technology associated with the MWx aluminum infrared temperature sensor is required.

Pyrometer Benefits:

• Conserve Energy
• Assure Desired Aluminum Properties
• Optimize Rolling Mill Speed

Wavelength Technology:

• MWx – Dynamic ESP Technology automatically corrects for variation of alloy, oxidation, elemental migration to the surface, and surface texture

Suggested Models:

• Pro MWx-AS-11, 575-1100°F / 300°-600°C
