In the energy-saving transformation of electromagnetic heating, there is a new industry that can make good use of electromagnetic heaters, that is, the textile machinery industry. There is a polypropylene spinning machine in this industry. There are different types of polypropylene spinning machines: polypropylene FDY spinning machine, polypropylene fiber POY spinning machine, polyester FDY spinning machine, polyester FDY spinning machine, polyester POY spinning machine, polypropylene BCF spinning machine. The main component of the polypropylene spinning machines is called the heat roller, which needs to be heated to a certain temperature and runs at high speed. The size of the heat roller is different, generally there are diameters Φ160 Φ180 Φ190 Φ210 Φ220. Hot roller length: 200-450mm, speed range: 750-5500m/min, godet surface temperature: ≤240℃-140℃, hot roller surface treatment: hard chrome plating, ceramic plating.

The current heating method of the heat roller is power frequency induction heating. Its disadvantage is that the heating ring is easily damaged. The most terrible thing is that it is easy to heat the central shaft of the motor and burn the motor. The newly developed all-digital application is applied to the heating roller of polypropylene spinning machines with high efficiency and energy saving, which completely solves the shortcomings of traditional heating and greatly reduces the cost for customers. The main advantages of using Xinhuiyuan electromagnetic heater for the heat roller are:

1. Make the surface temperature of the hot roller work area uniform, which can meet the requirements of different industrial yarns and civil yarns FDY spinning process

2. The surface temperature of the hot roller working area rises rapidly, energy saving is obvious, and the efficiency is greatly improved

3. After using the electromagnetic heater, the shaft of the heat roller motor will not damage the motor due to induction heating

4. The coil of the electromagnetic heater will not be damaged, reducing maintenance trouble and cost

5. The equipment has a complete system, simple structure, stable and reliable operation at high temperatures, and can meet the requirements of different fiber FDY spinning processes. It is an economical and reasonable choice for polypropylene FDY spinning.
