Microstructure 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...
متن کاملSimulation of Temperature Distribution in Hot Strip over Transfer Table
Transfer table is an essential stage between roughing and finishing rolling stands in a hot-strip rolling mill. High temperature and long time that strip is exposed to air at this stage cause a considerable heat loss that accounts for uneven temperature distribution, non-uniform surfaces, reduced product quality and increased production costs. Using thermal shields on the transfer table is cons...
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-Piece Constitutive Equation in Hot Rolling of Strip
Dimensional control of the work-piece in steel industry is of important interest. The main aspects in overcoming the thickness control are variations in material strength due to variations in chemical composition, work-piece temperature, reduction and the strain rate applied to the work-piece. In this paper based on the main parameters affecting the rolling force an attempt been made to give a ...
