Description

Technical Field

[0001] This utility model relates to the technical field of amorphous and nanocrystalline magnetic core processing equipment, specifically a heat treatment device for amorphous and nanocrystalline magnetic cores. Background Technology

[0002] The heat treatment of amorphous and nanocrystalline magnetic cores is a key process for preparing high-performance magnetic materials, and it is usually carried out under inert atmosphere (such as N2, Ar) and external magnetic field conditions.

[0003] However, existing heat treatment equipment has the following significant problems in terms of waste gas treatment and energy utilization:

[0004] 1. Energy waste: High-temperature waste gas generated during the heat treatment process is directly emitted without effectively recovering the waste heat, resulting in low energy utilization and increased production costs;

At the same time, the dust is easy to deposit in the pipes, causing blockage and affecting the normal operation of the equipment.
