Abstract：In order to improve the control ability of cooling system on the temperature of work-roll， a 3-Dimensional flow-thermal coupling model was built for the purpose of analyzing the effect of cooling structure parameters and the installation dimension on the cooling of work-roll. The results showed the further distance to the central impacting area in injection stream area of single nozzle， the faster of attenuation for convective hear transfer coefficient， i.e. the average convective hear transfer coefficient in central area is 4 times larger than the value in areas at both sides. So， the adjustment of inclined angle of nozzle based on proper reduced nozzle interval may get more evenness in cooling work-roll with higher cooling efficiency. Moreover， a large number of statistic on site show the transverse thickness distribution of hot rolling plate is more uniform and the control capability on crown of plate is increased about 0.05mm， by contrast between the cooling structure in hot rolling of plate before and after the improvement.
