Power frequency induction heater is used to heat the workpiece with frequency of 50 Hz, that is, there is no frequency conversion when heating, which is different from medium frequency or high frequency power supply. Intermediate frequency is a device that converts the power frequency from 50 Hz to 300 hz-1000 Hz, while the frequency of high frequency power supply is higher. 

Medium and high frequency are generally used in the heat treatment and quenching of metal, but not in the assembly. The biggest advantage of power frequency heating method is that it does not change the metallographic structure of metal workpiece after heating, and does not change the performance index of metal workpiece. In heating assembly, the hardness and material of metal parts can not be changed at will, so the power frequency induction heating method must be selected. The higher the frequency is, the more the structure of the metal changes, such as high frequency quenching, medium frequency smelting and so on. In the assembly of precision parts, power frequency induction heating is also used internationally.

If high frequency and medium frequency heating are used for assembly, quenching or annealing may occur, resulting in changes in hardness and microstructure of metal parts, resulting in cracking, wear and softening in the future operation process. In addition, the heating equipment after frequency conversion has radiation to the human body. The higher the frequency is, the stronger the field induction is, and the larger the frequency wave is, which is harmful to the physical and mental health of the operator.

The series of heaters produced by Zhuangyuan electric appliance are all power frequency induction heaters. According to different parts and different eddy current induction control methods, they are divided into several series of targeted heaters. Users can choose the matching heating equipment according to their actual needs. For details, please visithttp://www.czzydq.com/html/product/query.

状元电器制造有限公司前身是常州状元电器厂，因为较早从事工频感应加热设备的研发、生产，在该设备的制作上积累了丰富的经验，后来引进一些国外的先进技术与我们相结合，让所制造的工频加热器更贴合国内企业的操作习惯，具有牢固、抗疲劳等特征，加上电控系统的

Zhuangyuan Electric Appliance Manufacturing Co., Ltd., formerly known as Changzhou Zhuangyuan Electric Appliance Factory, has accumulated rich experience in the manufacture of power frequency induction heating equipment because it was earlier engaged in the research and development and production of power frequency induction heating equipment. Later, it introduced some foreign advanced technology to combine with us, so that the frequency heater manufactured by us can more conform to the operating habits of domestic enterprises, and has the characteristics of firmness and anti fatigue, In addition, the operation of the electronic control system is simple and convenient, which is deeply trusted by the majority of users. The service life, power saving and energy saving of the equipment are at the leading level in the industry.
