Temperature Measurements for Rolling Mill Applications

Non-Contact Temperature Sensors for Improved Process Monitoring and Greater Efficiency in Steel Manufacturing Process

Today’s increasing quality standards and higher energy costs demand more accurate and consistent temperature control in the steel making process.

Advanced Energy is an industry leader in process monitoring for all areas of steel manufacturing. Our MIKRON thermal imagers and Impac pyrometers provide the steel industry with cutting- edge technology, ease-of-use and dependability for monitoring critical parameters for productivity and product quality. These solutions are used throughout the steel

manufacturing process, where accurate temperature monitoring is required for improved control.

Steel manufacturing consists of high temperature manufacturing steps that use significant amounts of energy. Processes such as coke oven heating, continuous casting, furnace reheating, hot rolling, forging, sintering and annealing are becoming more and more expensive.

With energy prices at all-time highs, the cost of doing business has significantly increased. Steel facilities need the right tools to ensure they optimize energy usage across their facilities.

Advanced Energy addresses these needs by providing the most accurate measurements in the industry, enabling steel facilities to maximize their output. Without this level of accuracy, operators are forced to reheat more often than necessary, wasting valuable

Infrared sensors measure strip and sheet temperature so that rolling mill stands can be efficiently set to match the steel’s temperature. Sensors can be used to detect the presence of hot metal and accurately time the roll stand operation.

Pyrometers can be used to measure the roll temperature as water cools the roll during the quenching process. Steam is an issue with this application, requiring special spectral responses to accurately measure system temperature.

time, money and energy. Advanced Energy offers a wide selection of solutions for metal processing with proven reliability in severe production environments. They are developed specifically for high temperature applications in the steel and primary metals industries.

The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer and finally coiling up the lengthened steel sheet for transport to the next process.

A true classic: the versatile 140 series

They can selectively control the quench zones so that only the higher temperature part of the slab is quenched to the maximum extent allowed, resulting in greater working time. Ratio pyrometers e.g. ISR 6, ISR 6-TI, and IGAR 6 of Impac’s Advanced series, and the Impac ISR 12-LO, help to minimize the effect of steam interference.
