Quick annealing device for strip

Abstract

The invention discloses a quick annealing device for a strip. The quick annealing device comprises a device body, and a winding device arranged on the device body and used for moving and winding the strip and further comprises an annealing mechanism arranged on the device body, the annealing mechanism comprises an induction coil, a water cable inlet seat is arranged at one end of the induction coil, a water cable outlet seat is arranged at the other end of the induction coil, air pipes are arranged at the upper and lower portions of the induction coil correspondingly, a jet nozzle is arrangedat the position, close to the induction coil, of each air pipe, and a high frequency generator is arranged on the device body. According to the quick annealing device, the nanocrystalline strip can obtain more uniform and finer nanocrystalline after quick annealing, but also the disadvantage that the amorphous strip and the nanocrystalline strip become brittle after long-time annealing is avoided,meanwhile, the production process of the amorphous and nanocrystalline strips is made to be shorter, the productivity can be improved, the manufacturing process is shortened, moreover, the costs canbe saved, and the energy is saved.

Description

technical field [0001] The invention relates to the technical field of annealing treatment of amorphous strips and nanocrystalline strips, in particular to a strip rapid annealing device. Background technique [0002] Amorphous alloys have excellent soft magnetic properties such as high magnetic permeability and low magnetic loss, and have broad application prospects in the fields of distribution transformers, motors, and inductors. The preparation process of nanocrystals needs to be made into amorphous strips first, and then undergo appropriate nanocrystallization annealing to form a mixed structure of nanocrystals and amorphous materials. Nanocrystalline alloys have higher magnetic permeability and lower coercivity (closer to permalloy and cobalt-based amorphous). Although the saturation magnetic induction of nanocrystalline alloy is lower than that of iron-based amorphous and silicon steel, its high-frequency loss is much lower than these two alloys, and it has better co...

AI Technical Summary

Problems solved by technology

[0004] In 2007, Professor Ediger discovered that amorphous materials with ultra-low energy states can be prepared by vapor deposition, but the materials prepared by this method are all thin film samples, and its application is greatly limited

Therefore, the iron core after heat treatment is easy to form fragments during handling, hoisting, storage, transportation and transformer assembly, which is very dangerous to the operation of the transformer
