Problems solved by technology
[0004] At present, the width of the nanocrystalline strips produced by the crystallizer is basically less than 30 mm, and the thickness of the strips is more than 25 microns. The strips of this specification are very brittle, and the machinability and subsequent product size restrictions are relatively large.

Abstract
The invention provides a crystallizer for making ultra-thin strips of nano crystals. The crystallizer includes: a water seal seat, a main shaft, a copper sleeve, a support and a gland, and the main shaft, the support, the gland and the copper sleeve form a crystallizer cooling waterway and a belt-making platform, and it is characterized in that the water seal seat is provided with A plurality of rotating seals are used to improve the reliable sealing of cooling water at high speeds. There is a gap with a limited size between the copper sleeve and the support, and the copper sleeve is a copper sleeve with a limited material and a limited size. By optimizing the material, size and cooling structure of the copper sleeve, the invention can be used to stably manufacture ultra-thin nanocrystalline strips with a bandwidth of 50 mm and a strip thickness of less than 21 microns with high toughness and strong stability.
Description
technical field [0001] The invention relates to a crystallizer, in particular to a crystallizer for making nanocrystalline ultra-thin strips. Background technique [0002] The ultra-thin nanocrystalline ribbon prepared by single-roll quenching technology has excellent soft magnetic properties, such as low coercivity, high saturation magnetic induction, low remanence, high permeability, low magnetostriction coefficient, etc. Due to its excellent soft magnetic properties, it is often used as the core of common mode inductors on EMC boards that suppress electromagnetic interference. It not only has high magnetic permeability and can provide large inductance, but also has a certain degree of saturation due to its high saturation magnetic induction. anti-saturation ability. [0003] The crystallizer is the core component in the process of producing ultra-thin nanocrystals. Important performance indicators such as the surface quality and lamination coefficient of nanocrystalline ...
