Water Temperature Effect on Cooling Intensity for high Pressure Descaling Nozzles
Original language description
During continuous production in rolling mills, the hot steel is exposed to an oxidative atmosphere and oxide layers are formed on the surface. The oxide scale is typically removed using flat fan water nozzles fed by high pressure water in a process of hydraulic descaling. Use of these nozzles causes very intensive cooling, which is in most cases objectionable. One way to decrease this intensive cooling is to use water at a higher temperature. Laboratory experiments were conducted to study the degree ofinfluence the water temperature has on the heat transfer coefficient during cooling using the high pressure nozzles. Temperature measurements during descaling were used as input for inverse algorithm calculations. The heat transfer coefficients togetherwith surface temperatures were computed as a function of time and position. The results obtained for various water temperatures were compared and a slight decrease in the cooling intensity was found for higher water temperatures. The reas
