The magnetic yoke is a yoke iron made of laminated silicon steel sheets, which are evenly and symmetrically distributed around the induction coil. Its function is to restrain the leakage magnetic field of the induction coil from spreading outward, improve the efficiency of induction addition, and also reduce the heating of metal components such as the furnace frame as magnetic shielding, and also strengthen the inductor.
Medium frequency furnace The furnace body has a built-in imitation magnetic yoke. The magnetic yoke shielding can reduce magnetic leakage, prevent the furnace body from heating up, and improve efficiency. At the same time, the magnetic yoke acts as a support to fix the induction coil, so that the furnace body achieves high strength and low noise. The magnetic yoke is a crescent-shaped magnetic yoke made of cold-rolled silicon steel sheet and stainless steel splint. The joint surface between the iron core and the coil is a circular arc surface. The pressing place is a surface instead of a line in the past. This structure has good pressing effect and less magnetic leakage. After the silicon steel sheets are stacked, they are tightened with special splints instead of special through-core screws. This structure can make full use of the magnetic conductive area of the silicon steel sheets and reduce
Medium frequency induction melting furnace The possibility of local heating of the furnace body.
Magnetic yoke
Magnetic yokes usually refer to soft magnetic materials that do not produce magnetic fields (magnetic lines of force) themselves and only play the role of magnetic line transmission in the magnetic circuit. Magnetic yokes generally use soft iron, A3 steel, and soft magnetic alloys with relatively high permeability. In some special occasions, magnetic yokes are also made of ferrite materials.
Due to the existence of the magnetic yoke, we can transmit the magnetic lines of force produced by the energized coil (coil) and permanent magnet to the place we need. This is a bit like a circuit
A specially designed water-cooled radiator is installed between the magnetic yoke and the stainless steel plate clamp,
Medium frequency induction furnace In the running state, ensure that the upper magnetic yoke is at normal temperature to prevent the magnetic yoke from being deformed due to excessively high temperature, thereby strengthening the support of the induction coil and improving the overall strength of the furnace.
