Originální abstrakt

In the continuous casting of steel, there is a variety of dynamic situations, both planned and unplanned. The planned simulations include decreasing the temperature of the steel in the tundish or changing the steel grade. Unplanned situations can be breakout system interventions, equipment failure, etc. These situations can be optimally controlled by means of a modern type of controller-based, fuzzy-based predictive control algorithm by using the 3D non-linear transient temperature field model of the strand. A very fast dynamic solidification model was developed for the purpose to calculate these regulation models it real time. Software implementation and integration to the Level 2 automatization system is presented. Finally, advantages and disadvantages of this method of regulation are shown to the modeling of non-standard situations on a modern slab caster with 17 cooling loops in the secondary cooling zone.
