Název v původním jazyce

Influence of impact angle and pressure on spray cooling of vertically moving hot steel surfaces

Popis výsledku v původním jazyce

Cooling of vertically moving strips is used very often to obtain the required material properties. Water spray cooling has to be used when the high cooling intensity is needed. The water impacting on the strip surface is reflected and falls down betweenwater nozzles and strip surface. This falling water has a significant influence on cooling intensity and also on cooling homogeneity. It causes undesirable problems with strip deformation and controllability of cooling. A water knife is used to reflect falling water out from the area between strip surface and water nozzles. Water knife is formed by row of flat jet nozzles has also cooling effect on the moving steel strip. This effect was studied and measured. Heat Transfer and Fluid Flow Laboratory is equipped with testing device which allows vertical movement of a heated experimental plate (sheet). Three different size of flat jet nozzles were tested with different water pressure (water flow rate) and angle of water impact (inclination
