ABSTRACT:
The casting machine features a mold (10), a deflection plate (66) with a lower surface (80) for guiding cooling water (20) which is sprayed at high pressure and/or a supporting plate with an upper surface for guiding cooling water (20) flowing at low pressure. Both surfaces for guiding the cooling water (20) are made of insulating material. The electromagnetic shield (18, 76) is cooled on the inside at least in the active region. The mold housing (32) is preferably made out of a perforated sheet (34) which has been bent several ways. The active region of the shield is preferably in the form of a U-shaped or V-shaped shielding sheet and features an insert or coating for reducing the magnetic field of the inductor (12) increasingly in the upwards direction. The water-jetted surface (80) for guiding the cooling water is moved continuously backwards and forwards and/or tilted in a given rhythmic manner. As a result the curtain of water (22), which is independent of the electromagnetic shield (18), is moved up and down over the ingot (14) over a height (h).
