Zhuangyuan Electric has been producing general heavy-duty gears for a long time. In view of the characteristics of large diameter and heavy quality of oversized gears, it is no longer difficult to assemble interference heat sleeve of gears in ships and petrochemical machinery. In order to heat this "big" gear, technicians have carried out long-term testing and project tackling. It took more than one year for the design team to start from project approval, design, trial production and technical improvement, There are many practical problems in the process.

Gear induction heater is to use the power frequency heating principle to heat the gear induction. The inner hole of the gear is evenly heated and expanded by equal amount. The expanded gear can be matched with the shaft heat suit, which is widely used in the assembly of small and medium-sized gears. However, in the face of large gears, which are often weighed in terms of tons, the most important problem is whether the induction heating method can be used? Speed, efficiency, energy consumption and many other issues need to be demonstrated and tested. Therefore, the company invested a lot of R & D funds. After more than a year, the design team overcame many difficulties and finally developed a reliable and stable induction heating equipment. At present, the equipment has entered the production stage.

常州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自身相结合，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

Changzhou 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 technologies and combined them with itself to make the power frequency heater more suitable for the operation habits of domestic enterprises, with 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.
