Problems solved by technology

[0004] At present, there are still improvements to the silicon steel sheet yoke with high heat generation and high temperature, that is, in order to reduce the high heat generation and high temperature of the silicon steel sheet yoke, cooling water pipes can only be installed on the yoke for cooling, thus making the silicon steel sheet yoke The sheet yoke has a complex structure, consumes water and electricity, and has high production costs
Therefore, how to reduce the high power loss and high heat generation of the yoke has become an urgent technical problem to be solved.

Abstract

The invention relates to the technical field of induction heating furnaces, and discloses a non-conductive magnetic yoke based on an induction heating furnace and a method thereof. The non-conductivemagnetic yoke adopted by the method is of an integrated structure composed of soft magnetic powdery substances and cement and water, the integrated body structure is a brick body structure, or an arcface plate structure and a surface plate structure, and the soft magnetic powdery substances are silicon steel sheet powder particles or ferrite powder particles and permalloy powder particles. According to the non-conductive magnetic yoke based on the induction heating furnace and the method thereof, the problem that the heat productivity is large due to eddy currents generated by the silicon steel sheet magnetic yoke during the use process of the magnetic yoke manufactured by silicon steel sheets at the present is fundamentally solved, and the electric energy loss is reduced, the loss generated by the the silicon steel sheet magnetic yoke is effectively avoided, and the non-conductive magnetic yoke is simple in structure and low in production cost.

Description

technical field [0001] The invention relates to the technical field of induction heating furnaces, in particular to a nonconductive yoke and method based on induction heating furnaces. Background technique [0002] The yoke of the induction heating furnace is an important part of the induction heating furnace. It is installed on the periphery of the induction coil, so that as much magnetic field as possible can pass through the yoke to form a circuit, which is used to reduce the leakage magnetic field and achieve the purpose of shielding the magnetic field; [0003] The yoke of the intermediate frequency induction furnace is generally made of silicon steel sheets, and the silicon steel sheets are stacked to form a long arc-shaped block yoke. In use, the silicon steel sheet yoke has high power loss and high heat generation. [0004] At present, there are still improvements to the silicon steel sheet yoke with high heat generation and high temperature, that is, in order to red...
