    The process of descaling is a necessary part of forming processes, in which the clean surface before contact with a tool is required. Hydraulic or mechanical methods are the most commonly used methods for descaling. Hydraulic high - pressure descaling is currently the most exploited process. Scales can be very diverse in terms of chemical bonds and mechanical properties.

    Experimental work was concentrated on the study of descaling in relation to heat transfer and the quality of removing scale from the surface. Three types of measurements were implemented. The first one is a measurement of impact pressure distribution on spraying surface. The second is a measurement of temperature drop when a product is passing under the nozzle. The third type is a study of the surface quality where a defined layer of oxides is sprayed and its remaining thickness is evaluated. The heat transfer test is evaluated by inverse task and the results are prepared in a form of boundary conditions suitable for using in a numerical model.

    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.
