装置。 A position detector that detects the position of the rolling device, a load setting device that stores the rolling load range in which the oil film thickness should be measured, and the actual rolling load output from the load cell device and the load command value output from the load setting device. a constant load control device that controls the rolling down device until the deviation of the oil film becomes zero, and a speed setting device that stores the rolling speed range at which the oil film thickness is to be measured and outputs a speed command value to the ASR system that controls the rolling speed. , an oil film thickness compensation measurement controller that instructs the output procedure to the load setting device and speed setting device, and the rolling device being controlled by the constant load control device, the output from the position detector when the rolling speed is zero. The oil film thickness is calculated from the position of the rolling down device outputted from the position detector when the speed is increased, and the oil film thickness storage device stores the relationship between rolling speed and oil film thickness for each rolling load. An oil film thickness compensation control device for a rolling mill, characterized in that:
