PROCESS AND APPARATUS FOR CONTROLLING THE FLOWS OF LIQUID METAL IN A CRYSTALLIZER FOR THE CONTINUOUS CASTING OF THIN FLAT SLABS

摘要

The present invention relates to a process for controlling the distribution of liquid metal flows of in a crystallizer for the continuous casting of thin slabs. In particular, the process applies to a crystallizer comprising perimetral walls which define a containment volume for a liquid metal bath insertable through a discharger placed in the middle of the bath. The process includes arranging a plurality of electromagnetic brakes, each for generating a braking zone within said bath, and activating these electromagnetic brakes either independently or in groups according to characteristic parameters of the fluid-dynamic conditions of the liquid metal within the bath.
