There is a new industry in the energy-saving electromagnetic heating can be very good use of electromagnetic heaters, that is, the textile machinery industry, this industry has a polypropylene spinning machine, it has different types: polypropylene FDY spinning machine, polypropylene FDY spinning machine , Polypropylene POY spinning machine, polyester FDY spinning machine, polyester FDY spinning machine, polyester POY spinning machine, polypropylene BCF spinning machine. . . . One of the most important parts of this machine is the hot roll, which needs to be heated to a certain temperature and it is running at high speed.

Polypropylene spinning machine on the different size of the heat roller, generally has a diameter Φ160 Φ180 Φ190 Φ210 Φ220. Heat roller length: 200-450mm, speed range: 750-5500m/min, surface temperature of guidewire plate: ≤240°C-140°C, hot roller surface treatment: hard chrome plating, ceramic plating.

The current heating method of the hot roller is industrial frequency induction heating. Its disadvantage is that the heating coil is easily damaged. The most frightening thing is that the center shaft of the motor is easily heated and the motor is burned out. The newly-developed all-digital application of high-efficiency and energy-saving in the hot roll heating of the polypropylene spinning machine completely solves the shortcomings of traditional heating and greatly reduces the cost for customers.
