Abstrakt EN: Continuous furnaces are commonly used for steel billets reheating before a rolling operation. These furnaces are mostly gas-heated, their length can be a several tens of meters and the minimum charge temperature should be typically from 1100 to 1200 °C before the rolling mill entry. Energy consumption and environmental impact of such facilities are significant and, therefore, an optimization of their operation is an important question. It is necessary to perform a number of measurements to set-up of an optimization system correctly. The direct charge temperature measurement procedure using infra-red detectors is introduces in this contribution. The most important problems of charge emissivity setting and ways of the emissivity determination are discussed. The measurement set-up is described and measured temperatures examples are shown.
