ABSTRACT:
In vertical thin-bodies continuous casting machines in which the liquid metal is cast in a mold formed by a pair of counter-rotating rolls with parallel longitudinal axes lying in the same horizontal plane and by a pair of containment plates facing onto the flat ends of the rolls, an electromagnetic device is introduced which produces a field of electromagnetic forces in a desired and given space formed between the plates and roll ends, the orientation and intensity of the forces being such as to impede leakage of liquid metal between the plates and the rolls. With this device the contact between plates and rolls is eliminated, as is the relative wear. Moreover, flat metal products are obtained that are substantially free from surface defects on the edges. Lastly, the absence of flashes on the edges due to metal infiltrating and solidifying between plates and rolls markedly decreases the possibility of jamming the machine.
