1. A rolling load prediction device for predicting a rolling load of a rolling mill for rolling steel, the device comprising:
circuitry configured to:
predict the rolling load of the rolling mill in a case where the steel is rolled under an operating condition for prediction, by inputting the operating condition for prediction into a rolling load prediction model that has been trained with operation record data including at least a factor related to a temperature of the steel as an input variable and an actual value of the rolling load of the rolling mill as an output variable;
calculate a setting value of the rolling mill using the predicted rolling load of the rolling mill; and
control the rolling mill according to the calculated setting value, wherein
the factor related to the temperature of the steel includes a temperature of a skid rail that supports the steel in a heating furnace.
