近年来，国内外各种类型的除铁设备基本上可以适应各种不同使用场合的要求。们申力和愎诺等皮带输送系统中目前普遍使用的电磁式除铁设备，因其连续工作，励磁线圈中一直通有直流电，因而产生了所需的磁场，达到除铁的目的，但同时也产生了大量热量。这样，耗电大、线圈易老化 In recent years, various types of iron and steel equipment at home and abroad can basically meet the requirements of different occasions. We Shen Li and Connaught and other belt conveyor system commonly used in the current electromagnetic iron removal equipment, because of its continuous work, the excitation coil has been through a direct current, resulting in the required magnetic field, to achieve the purpose of removing iron, but at the same time Also produced a lot of heat. In this way, power consumption, easy to aging coil
