A rolling load prediction method predicts a rolling load of a rolling mill for rolling steel and includes predicting 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.

A surface inspection method for a steel sheet coated with a resin, includes irradiating the steel sheet with sheet-like light, which has been linearly polarized at a predetermined polarization angle, at an incidence angle different from Brewster's angle of the coating by a predetermined angle or greater; and imaging linearly-polarized light of a polarization angle of 0 degrees at an acceptance angle different from a regular reflection angle of incident light by a predetermined angle. Accordingly, it is not necessary to change the incidence angle and the acceptance angle depending on resin components and it is possible to inspect a substrate steel surface of the steel sheet highly accurately without observing abnormalities in the coating itself.
