Molten metal is applied under pressure, through a slit nozzle (10), to a moving cooling body (7). The slit nozzle (10) is arranged directly adjacent to the surface of the cooling body (7). The cooling body (7) moves past the slit nozzle (10) at a surface velocity of 100 to 2000 m/min. The distance between the slit nozzle (10) and the surface of the cooling body (7) is 0.03 to 1 mm. These dimensions permit high-speed production of continuous polycrystalline metal strips and amorphous metal strips with hitherto unachieved dimensions of isotropic thickness and other isotropic properties, e.g. magnetisability. <IMAGE> |
