Rolling conditions in hot strip mills and their influence on the performance of work rolls
The mechanical rolling conditions in hot strip mills are precisely defined by various variables, which are taken directly froth the rolling schedule (separation force, torque. speed. strip thickness) or calculated from figures of the rolling schedule and dimensions of the mill (strip reduction, roll diameter etc.). These variables allow to describe the mechanical rolling conditions of all passe...
متن کاملTension Control with ARHC Scheme for Hot Strip Finishing Mills
This paper presents a design procedure of the ARHC(Adaptive Receding Horizon Control) of the looper-tension controller in hot strip finishing mill. The controller is applied to satisfy the constraints of the control input and attenuate the disturbance of the actuator. The system matrices of the looper model are periodically updated during online simulation. Moreover the closed loop stability of...
متن کاملPrediction of Work Roll Initial Crown according to Desired Strip Profile in Hot Rolling
The final hot strip profile is a superposition of the roll initial crown, the roll bending and flattening crown, the roll wearing crown and the roll thermal crown. In this research, linear regression models are proposed to predict the roll force, the roll wearing crown and the roll thermal crown using experimental data provided by Mobarake Steel Complex (MSC). The short beam theory based on ela...
متن کاملOptimum Work Roll Profile Selection in the Hot Rolling of Wide Steel Strip Using Computational Intelligence
The finishing train of a hot strip mill has been modelled by using a constant volume element model. The accuracy of the model has been increased by using an Artificial Neural Network (ANN). A non-linear Rank Based Genetic Algorithm has been developed for the optimization of the work roll profiles in the finishing stands of the simulated hot strip mill. It has been compared with eight other expe...
متن کاملMicrostructure prediction and control in hot strip mills *Dr
A key determinant of the quality of hot-rolled strip is mechanical properties lying within the tolerance range. Traditionally, this is done by testing samples which is costly, time-consuming and ties up stock awaiting test results. An alternative is given by MicroStructureMonitor, a computer model-based system which calculates the required quality parameters rather than measuring them and addit...
