Abstract
Method and device for continuous or semi-continuous casting of metal in a mould (10), in which a primary flow (P) of molten metal supplied to the mould through a port (21, 22) in a pouring nozzle (20) is acted on by static magnetic fields (30, 31, 32, 33) at a lower level (L) which is at or downstream of the nozzle port and at an upper level (U) which is between the top end of the mould and the nozzle port (21, 22). Magnetic circuits provided at both levels apply magnetic fields (30, 31, 32, 33) acting within two main zones (UA; UB; LA; LB) on opposite sides of the nozzle (20), and an intermediate zone (UI, LI), substantially subtending the width of the nozzle tube, is essentially free from magnets so that a substantially weaker magnetic flux density acts on the melt in the intermediate zone than in the main zones.
