Based on the measured data from a hot stripmill, the rolling force in roughing was predicted by means of BP neural networks which adopted two kinds of training methods.
Generally speaking, the head and tail of the hot strip will bring out tongue type and fish tail type bug and its temperature will be usually lower when it passes through the roughingmill.
