Large-capacity nanocrystalline thin strip production system

Abstract

The invention discloses a large-capacity nanocrystalline thin strip production system. The large-capacity nanocrystalline thin strip production system comprises a machine frame platform, wherein a travelling track is arranged on the machine frame platform, a smelting station and a steel casting station are arranged on the travelling track, a vacuum furnace system which does reciprocating motion between the smelting station and the steel casting station is arranged on the travelling track in a sliding mode, a nozzle ladle mechanism corresponding to the vacuum furnace system is arranged at the position, corresponding to the steel casting station, below the machine frame platform, a nozzle ladle constant liquid level closed-loop control system for controlling the opening and closing amplitudeof a water outlet of the vacuum furnace system is electrically connected between the nozzle ladle mechanism and the vacuum furnace system, a crystallizer is correspondingly arranged below the nozzleladle mechanism, an automatic strip collecting device is correspondingly arranged on the strip outlet side of the crystallizer, an on-line thickness measuring device is arranged between the crystallizer and the automatic strip collecting device, and a strip thickness constant closed-loop control system for controlling the distance between the nozzle ladle mechanism and the crystallizer is electrically connected between the on-line thickness measuring device and the nozzle ladle mechanism. The large-capacity nanocrystalline thin strip production system is simple in structure, reasonable in design and high in production efficiency.

Description

technical field [0001] The invention relates to a production equipment structure of nano crystal strips, in particular to a large-capacity production system of nano crystal strips. Background technique [0002] Iron-based nanocrystalline strips are known as the most cost-effective soft magnetic materials for their excellent soft magnetic properties, especially nanocrystalline thin strips with a thickness of less than 20um, low eddy current loss, and excellent high-frequency properties. favor. For iron-based nanocrystalline broadband with a width of more than 60mm, it is the preferred material for magnetic shielding and wireless charging cores for mobile phones. With the development of science and technology and the improvement of strip production technology, the method of obtaining nanocrystalline thin strips in batches in the domestic industry is the pressure spray strip method. Through constant pressure control, the pressure at the nozzle is kept constant, thereby obtain...

Problems solved by technology

[0004] However, due to the limitation of the volume of the nozzle package, the current maximum tonnage of the iron-based nanocrystalline pressure spray belt does not exceed 200kg at one time.

Especially in the mass production of iron-based nanocrystalline ultra-wide and ultra-thin strips, it is difficult to achieve mass production due to the limitation of the volume of the nozzle box. At present, this has become a bottleneck restricting the mass production of iron-based nanocrystalline strips.

However, it is more difficult to manufacture a large-capacity nozzle package, and once a crack occurs in a large-capacity nozzle package, it will cause great harm and loss to the staff and production equipment.
