Abstract

The invention discloses a method and system for preparing a winding-free high-efficiency amorphous ribbon. The method comprises the steps that a plurality of small-bore small melt spraying holes are formed in a melt nozzle at certain intervals, and after a mother alloy molten mass injected out of the small-bore small spraying holes is sprayed to a rapid quenching cooling roll face, the amorphous ribbon is formed independently; the system for preparing the winding-free high-efficiency amorphous ribbon comprises a blending device, a throw-preparing device and an amorphous ribbon automatic collector. The mother alloy is heated to be molten through the high-frequency induction technology, and the alloy melt is sprayed to the cooling roll face which is provided with a transverse groove and rotates fast through the spraying holes with the diameter smaller than 1 mm, wherein the surface of the cooling roll face is polished. The alloy melt sprayed to the cooled roll face is fast cooled on the smooth roll face to form the amorphous ribbon with even thickness and width.

Description

technical field [0001] The invention belongs to the technical field of amorphous ribbon preparation, and in particular relates to a non-winding and high-efficiency amorphous thin ribbon preparation method and a preparation system. Background technique [0002] In order to obtain the excellent properties and unique microstructure of amorphous alloys, it is required to directly quench from the molten state to a temperature below the freezing point at a very high cooling rate during the preparation process. In order to meet the special quenching process requirements of amorphous alloys, the single-roll quenching technology is currently the most widely used technology for preparing amorphous thin strips with a width of more than 1 cm. However, for thin amorphous strips with a width of less than 0.5 cm, Due to the serious intertwining phenomenon, the existing single-roll rapid quenching technology is difficult to achieve industrial batch production of amorphous thin strips. The ...
