Problems solved by technology

The existing nozzles are integrally formed, and deformation or cracking will occur during actual use, which will easily cause the quality of the produced amorphous alloy strips to be unqualified, and there is no soft connection layer at the bottom of the existing nozzles. They are all rigid connections, and it is easy to break the nozzle, resulting in steel spraying and accidents

Abstract

The invention relates to a novel floating nozzle comprising a high-temperature-resistant nozzle body. A nozzle seam is arranged in the high-temperature-resistant nozzle body in the length direction, and a slit is arranged in the high-temperature-resistant nozzle body in the width direction. Soft connection between the nozzle and a nozzle package is realized, deformation or cracking of the nozzle is prevented through the slit, and service life is long.

Description

technical field [0001] The invention relates to a metal thin strip manufacturing technology, in particular to a nozzle for rapidly quenching an amorphous alloy thin strip, in particular to a nozzle for spraying an amorphous alloy thin strip. Background technique [0002] At present, amorphous alloy soft magnetic material is a new type of soft magnetic material developed in the past 30 years. This alloy has replaced most of Ni Fe permalloy soft magnetic alloy with high Ni content. It is not suitable for some silicon steel and ferrite. There are more and more applications in new application fields. This kind of soft magnetic alloy has excellent magnetic properties, short manufacturing process, energy saving and environmental friendliness in the manufacturing and use process. It has attracted more and more people's attention, and its output has increased year by year. [0003] The nozzle is a key process equipment component for the production of amorphous alloy thin strips, and...
