ROLLING MILL

PURPOSE:To effectively control thermal crowns and to control the rolling with high accuracy by integrally moving both a roll cooling nozzle mechanism and a rolling roll in the same direction. CONSTITUTION:An upper work roll 2 is connected to a metal chock 8, a 2nd moving block 18 is provided with a roll cooling nozzle mechanism 11, and a flow regulating valve is individually set on nozzles 13. When the roll 2 is moved through a movement mechanism 15 in the axial direction for control of rolling, the nozzles mechanism 11 also moves in the same direction, so that the relative position between the roll 2 and the nozzles 13 is unchanged and a cooling control for thermal crowns is effectively performed during roll movement. Therefore, a compensation control for thermal crowns during roll movement is effectively performed to control the rolling with high accuracy.
