Abstract

Steel production is connected with high temperatures at which the steel reacts with oxygen in the surrounding atmosphere, creating scales on its surface. Scales are eliminated by row of high pressure flat jet nozzles. The flat jets overlap in an overlapping area. This area is dramatically overcooled during the typical configuration of the nozzles with an offset angle of 15° and an inclination angle of 15°. For this paper, both the typical and a new configuration with an offset angle of 0° were measured. Cooling homogeneity measurements were made to see the improvement in cooling homogeneity with the new configuration. Spray impact pressure distribution measurements were made to observe the size and shape of pressure distributions in the overlapping area for both the configurations. Obtained results are presented and improvements achieved with the new configuration are discussed.
