Abstract

The invention relates to the preparation of especially metallic or semi-metallic bands or sheets, particularly with a microcrystalline or amorphous structure. According to this process, an electrically conductive molten material is made to flow from a tank through a nozzle, to form a strip of substantially rectangular cross-section, which is subsequently solidified. According to the invention, the form of the strip of liquid material is stabilized, after it has been shaped and before solidification, as a result of a mechanical surface effect induced by an alternating magnetic field.
