A heat Rough Rolling line Calculation of short-stroke curve parameters

Present invention provides a short stroke Rough Rolling line curve parameter calculation method, hot-rolled strip automatic control technology. The present invention employs a multi-segment polyline, using the neural network to predict the rolling member is not applied end to end control of the short stroke, this passes through the rolling forward and reverse rolling after a time (if this is not the end of pass pass) the amount of bandwidth loss generated, after which the reversible rolling pass parameter exchange rolling head and tail, and rolling member according to the width of the inlet head and tail bias and the predicted roll width reductions, determined vertical roll pass short stroke curve parameters. Short stroke curve parameters present invention relates to a calculation method, good adaptability, high accuracy, and ease of debugging and maintenance, help to improve the hot rolling finished product rate.
