Problems solved by technology

[0006] The purpose of the present invention is to provide a non-slitting and non-coiled amorphous ribbon preparation method and preparation system, aiming to solve the redundant process existing in the current amorphous ribbon spinning process, and avoid the current amorphous ribbon preparation process. Coiling, rewinding, slitting and other processes, the amorphous strip preparation process directly obtains the amorphous strip segment, eliminating the need for coiling and slitting, avoiding the introduction of stress during the coiling and slitting process, improving the production efficiency and quality of the amorphous strip, and reducing the amorphous Labor cost and equipment investment in the production of crystal soft magnetic devices

Abstract

The invention discloses a slitting-free non-winding amorphous ribbon preparation method and a preparation system. According to the preparation method, a plurality of grooves are formed in a cooling roller face perpendicular to the rotating direction of a rapid-quenching cooling roller so that an amorphous ribbon can be automatically broken at groove positions in the throwing process, and a segment-shaped amorphous ribbon is formed. The preparation system comprises a melting device, a throwing device and an automatic segment-shaped amorphous ribbon collector. By means of the preparation method and the preparation system, the segment-shaped amorphous ribbon with a needed length can be directly obtained in the throwing process of the amorphous process, the redundant procedures that in the prior art, the amorphous ribbon is wound firstly and then is disengaged from a disk and slit are omitted, the production efficiency is improved, the production cost and the equipment investment are reduced, and meanwhile, the situation that as stress action is introduced by winding, the performance of the amorphous ribbon is reduced is avoided.

Description

Technical field [0001] The invention belongs to the technical field of amorphous thin ribbon preparation, and in particular relates to a method and system for preparing an amorphous thin ribbon without slitting and non-coiling. Background technique [0002] In order to obtain the special microstructure of the amorphous alloy, it is required to quench directly from the molten state to the temperature below the freezing point at a very high cooling rate during the preparation process. Single-roll rapid quenching technology is currently the most widely used technology. [0003] In the current technology, the continuous ribbon spinning method is used to continuously spray the alloy melt through the nozzle onto the surface of the high-speed rotating cooling roller to form a continuous amorphous ribbon. The amorphous ribbon made in this way is continuous from beginning to end, and the amorphous ribbon made from a furnace of melt usually has a length of more than several kilometers. For...
