Original Abstract

The cooling homogeneity is one of the most important factors which must be considered when designing the cooling sections for hot rolling of thin sheets. The inhomogeneous cooling may origin an undesirable thermal distortion. The cooling homogeneity is mainly influenced by the water distribution of the cooling section. And so, one way how to measure the cooling homogeneity is to measure the impact pressure distribution of the cooling section. Another way is to measure the surface temperature distribution of a steel sample during the cooling process. There are two ways how to measure surface temperature and temperature field: contact and non-contact. Contact measurements are conducted with the help of thermocouples and noncontact measurements use an optical measurement, i.e. using an infrared-scanner. Each of these methods has their advantages and disadvantages. The comparison was demonstrated by the experimental cooling measurement of a stainless steel sheet done by full cone water nozzles.
