THIN STRIP PRODUCTION APPARATUS

PURPOSE:To produce thin strip metal having uniform thickness stably by detecting displacements of inclination and gap, etc., of a nozzle to a drum and adjusting them to normal values at producing the thin strip metal by injecting molten metal on a drum with high speed rotating from the nozzle. CONSTITUTION:The molten metal is injected on the surface of the drum 2 made of Cu as cooling body, which is rotated at high speed, through the nozzle 1 and cooled rapidly to produce continuously the thin strip metal 4 having amorphous quality on the surface of the drum 2. In this case, gap and inclination of the nozzle 1 to the drum 2 is measured by sensors 3a, 3b fixed to the nozzle 1, and the measuring value is transmitted to a measuring part 7 and then the gap and inclination of the nozzle 1 to the drum 2 is adjusted to the normal value by a controlling device 6, which controls a nozzle driving device 5, to produce constantly and continuously the thin strip metal having uniform thickness on the rotating drum 2.
