Original Abstract

The cooling of working rolls is an important process in the hot rolling technology. The optimal cooling of rolls can be designed with respect to two aspects. The first is the wearing of a roll where high temperature decreases the durability of the surface layer. The second aspect is a thermal deformation of a roll. This is critical for the shape and tolerance of flat products and an increasing importance of this aspect can be studied in1. Cooling at rolling mill should be designed with consideration to both aspects2. Finding optimum pressure and flow rate is a difficult task even if we search only for cooling “with the highest intensity”. In regards to water quantity, the measurement shows that the phrase “more is better” is not valid here. In other word – an increase in the amount of water can cause a decrease in cooling intensity.
