The flatness target curve is important in the control theory. accuracy of an factor to determine load means and quality. Aiming at defect that crown each pass after rolling cannot be controlled quantitatively traditional formulation cold rolling, a new method considering was proposed. Specifically, can set by combining total proportional change hot field instability discrimination model field. ...

Production of thin steel strips with 0.18-0.26 mm thickness is about 0.75 of annual production of the two stand reversing cold mill, while its efficiency is 60%. This is due to the fact that after montaging the grinded work rolls, rolling thin steel strips (with thicknesses less than 0.18 millimeters) is unavailable. Initially, unsuitable surface roughness, the friction between rolls and the st...

Hydraulic Automatic Position Control (APC) is a very important part of rolling mill for magnesium plate rolling. The control effect of automatic position control system influences the quality of the rolled product directly. APC system is an essentially nonlinear, time delay, time-varying, large inertia, multivariable and coupling complex system, which increase the designing difficulty of contro...

This research studies monitoring of Fe2O3 iron particle size produced in industrial companies on the premises a hot rolling mill. The analysis used distribution curve method - by intensity. determined which particles occur most often sample, what is average size, smallest and largest particles. Digitization individual procedures technological processes provides data that can be worked with at g...

A fuzzy logic control (FLC) is designed to maintain constant tension for tandem rolling mills. Genetic algorithm (GA) is used as self-organization technique for FLC to locate the optimal parameters. Simulation results verify the superior performance of genetic fuzzy controller. Keywords-tension control, fuzzy logic, genetic fuzzy system, rolling mill.
