Application of relatively equal load distribution method in rough rolling schedule

Based on the feature of hot plate rough rolling, in the real-time data, a large number of production data analysis, Mathematical models are set up. In use of the relatively equal load sharing method with constraints, which are condition of bite, maximum allowable rolling force, rolling torque, and motor power, etc, on the basis of mathematical model, programs and measures of mill load distribution are proposed, and the optimization software Visual Basic of the rough rolling load distribution is completed. The result shows that rough load distribution is broadly similar, reducing the rolling passes and improving the productivity of rolling. The application example of this method is introduced and analyzed which is testified its flexibility for on-line process control system.
