2.Application of ferrite cores and impeders
In the use of high frequency induction heating method for metal welding, using ferrite cores can greatly improve the induced electromotive force in the welded tube and increase the welding power. The magnetic flux in the induction coil is centrally distributed in the ferrite cores, and the magnetic flux between the induction coil and the welded tube is relatively reduced, thus improving the welding efficiency. Therefore, in high frequency welding, the performance of ferrite cores greatly affects the welding efficiency, quality and stability of welded pipe, and also affects the energy consumption of steel pipe welding.
In order to satisfy the high frequency welded pipe industry diversification, personalization, high-end development needs, we developed a new type of soft magnetic ferrite materials, and developing the advanced ferrite cores forming and sintering process, magnet magnetic high density, high strength, good thermal stability, can effectively improve the efficiency of welding, the welding energy consumption were reduced, at the same time improve the quality of weld.
In addition, as part of the power is consumed in the ferrite cores during high-frequency welding, it is necessary to use cooling liquid cooling, otherwise the ferrite cores will overheat and the magnetic property will decrease or disappear, which will reduce the welding efficiency. Magnet bare when used, due to welding heat directly ACTS on the magnet, and prone to bubbles when cooling liquid cooling, reduce the magnet cooling efficiency, so the company developed a magnet outsourcing casing, impedance and other devices and accessories, such magnet is always at work is covered by cooling fluid, both maintained the low temperature, and avoid the bubbles, It can effectively improve the cooling effect of ferrite cores, improve welding efficiency and weld quality.
