Inter-rolling stand cooling devices are provided. When determining rolling speed and cooling water flows based upon the material temperature measured further upstream than the rolling mill, material positions detected by sensors on the mill line and information pre-determined in accordance with the production plan that includes material Steel Grade, rolling mill entry side material thickness, product strip thickness target value and rolling mill delivery side temperature target value, the positions in the longitudinal direction of multiple calculation points on the material are calculated based upon initial information, the heat generation and heat loss occurring at each rolling stand are calculated at every calculation point based upon the initial information and the positions in the longitudinal direction of the multiple calculation points, the rolling mill delivery side material temperature is calculated based upon the various heat generation and heat loss, and similar operations are repeated until the deviation of the rolling mill delivery side temperature from the target temperature is contained within permissible limits.
