Temperature measurements after the descaler confirm the product will arrive at the roughing stands within required temperature tolerances.

Scale is removed by high-pressure water jets as the steel is being rolled through the scalebreaker. The scale grows back quite quickly, so measurements need to be fast to obtain the true metal temperature. 

Accurate knowledge of the true metal temperature of the steel allows greater quality and process control, ensuring the steel product meets the requirements of the rolling mill. Real-time thermal imaging with Landscan verifies uniform temperature distribution prior to rolling, reducing the production of scrap material and preventing damage to the rollers.
