Zusammenfassung:	A method for estimating an outlet temperature of a finishing mill is provided. The method includes the following steps: performing regression on historical operating parameters and historical outlet temperatures to obtain a big-data model; using the big-data model to calculate a calculated temperature of big-data model; subtracting a theoretical outlet temperature from an actual outlet temperature to obtain a learned compensation value; subtracting the calculated temperature of big-data model from the actual outlet temperature to obtain a compensation value of big-data model; calculating an absolute ratio of the learned compensation value to the compensation value of big-data model, and multiplying the absolute ratio by the learned compensation value to obtain a compensation correcting value; summing the theoretical outlet temperature, a compensation value of coil temperature, a compensation value of batch, and the compensation correcting value to obtain an estimating outlet temperature of the finishing mill.
