Problems solved by technology

[0005] Domestically made magnetic components are generally aimed at the magnetic conduction requirements of motors. For example, Chinese patent CN102130543 discloses a soft magnetic composite material with high magnetic permeability. It uses ultra-fine raw material iron powder, and there are many types of coatings. Relatively many, at the same time, the manufacturing process is complicated, and there are no application examples at present
There are also manufacturers of magnetizers for induction coils in China, but their performance cannot meet the performance indicators imported from abroad, especially the service life is far from enough. Although the price is low, the unstable performance may cause a large number of workpieces to be scrapped, which is not worth the loss.

Description

technical field [0001] The invention belongs to the technical field of high-frequency heat treatment equipment materials and parts manufacturing, and relates to a new magnetic material manufacturing method used in an AC inductor and a related inductor component manufacturing process, in particular to a high-frequency soft magnetic composite material and its A method for preparing a magnetic conductor member by using the material. Background technique [0002] Generally, induction heaters or induction coils are used to quickly heat conductive metal materials. When the workpiece is placed in a variable magnetic field, the alternating current generated inside it will heat the workpiece, which can quickly heat the workpiece. In this process, the magnetic field of the induction coil is introduced into the metal tool for rapid heating, so it is necessary to have sufficient density of magnetic lines of force to pass through the workpiece in a short time to generate alternating curr...
