Application of Magnetic Yokes in Medium-Frequency Induction Furnaces
Sep 24,2020
The magnetic yoke is made of silicon steel laminations and is evenly and symmetrically arranged around the induction coil. Its function is to suppress the leakage flux from the induction coil, preventing it from spreading outward and thereby improving the induction efficiency. In addition, the magnetic yoke can also serve as a magnetic shield, reducing heating of metal components such as the furnace frame and reinforcing the inductor itself.
Medium-frequency furnace body The built-in contour-following magnetic yoke reduces magnetic leakage, prevents the furnace body from overheating, and enhances efficiency. At the same time, the magnetic yoke supports and secures the induction coil, enabling the furnace body to achieve high strength and low noise levels.
The magnetic yoke is a crescent-shaped structure composed of cold-rolled silicon steel sheets and stainless steel sandwich plates. The mating surface between the magnetic core and the coil is curved, and the pressing is done on the surface rather than along lines as in the past, resulting in excellent compression performance and reduced magnetic leakage.
Magnetic yoke The composition and working principle
A magnetic yoke is typically made of soft magnetic materials that do not generate magnetic flux (magnetic lines) themselves; rather, it serves solely to guide and transmit magnetic lines within the magnetic circuit. Magnetic yokes are commonly constructed from soft iron, 3 steel, and soft magnetic alloys with high permeability. In certain special cases, magnetic yokes can also be made from ferrite materials. Thanks to the presence of the magnetic yoke, we can direct magnetic lines—generated by permanent magnets or other sources—precisely to the locations where they’re needed. This process is somewhat analogous to how an electrical circuit functions.
A specially designed water-cooled radiator is installed between the yoke and the stainless steel plate clamp. During operation of the medium-frequency induction furnace, the upper magnetic yoke remains at room temperature, preventing it from deforming due to high temperatures. This, in turn, strengthens the support provided to the induction coil and enhances the overall structural integrity of the furnace.
