Abstract

The cooling nozzles arrangement is an important factor that affects the uniformity of the work roll temperature during hot rolling. In order to improve the work roll temperature distribution, a 2D calculation model of the unsteady temperature field of the work roll was established and the cooling nozzles arrangement was optimized based on the ANSYS finite element software. And it could be found that the temperature differences between the middle and the edge of the work roll would be reduced 7~8°C when the cooling water crowns of the work roll on F1~F7 stands were increased. Two optimization methods were adopted, one way was: the nozzle spacings of each row were the same. By changing the flow of the nozzles, the nozzles were in gradient arrangement from the middle to the edge of the roll according to the flow. The other way was: the nozzle type and flow rate of each row were the same. By changing the nozzle spacings, the nozzles were arranged from the middle to the edge of the roll according to the nozzle spacings.
