In order to improve the cooling effect of the strip in the normalised cooling section of orien-ted silicon steel,the heat transfer characteristics of gas jet cooling under different inlet pressures,strip thickness,strip movement speed,jet height and nozzle spacing are calculated using the numerical sim-ulation software Fluent.Calculations show that the average temperature of the strip after cooling increa-ses with strip thickness,movement speed,nozzle spacing and nozzle height,and is negatively correla-ted with the value of the inlet pressure.The inlet pressure,the thickness of the strip and the speed of movement mainly affects the rate of temperature drop of the strip,strip temperature uniformity along the width depends on the height of the jet and the nozzle spacing,the temperature uniformity of the strip is better when the spray height is 300 mm and the nozzle spacing is 75 mm.The calculation results pro-vide theoretical guidance for the actual production of strip steel.
