Many people are not familiar

Many people are not familiar with the electromagnetic heating roller, and many people will confuse the electromagnetic heating roller and the electric heating roller, so let's compare them together! 1. The problem of the application of heat transfer oil electric heating roller in the production line is: for the heating temperature above 250 ℃, the heat transfer oil can't be used, only can be used below 200 ℃, and there are oil leakage, carbonization and safety problems, which belong to the non optional range. 2. The electric heating roller can reach 250 ℃ or even 400 ℃. Its disadvantage: low temperature uniformity, generally above ± 10 ℃. 3. The temperature detection and control errors are large. There are two detection methods: one is to detect the space temperature in the roll, which is very different from the roll surface temperature (there is a temperature difference of 40-100 ℃ according to different temperatures and production products), and the roll surface temperature change cannot be detected. Temperature control is basically an open-loop control state, which can not meet the production requirements. The other is to detect the roller surface temperature, which is divided into contact type and non-contact type. The contact type is that the contact element is attached to the roll surface (non working surface), which has wear on the roll surface and detection element, low life, affects the quality and appearance of the roll surface, and can not directly detect the temperature of the working surface. The non-contact temperature measurement is greatly affected by the ambient temperature and has large measurement error, so it is difficult to meet the production process requirements of top companies. The heating element of the electric heating roller has high heating temperature, short service life and large maintenance, so the electric heating roller can only be used in the production of low-grade products with low temperature control requirements and low temperature uniformity requirementsOn, such as corrugated paper, non-woven fabric and other products, basically belong to the non optional range. 4. Electromagnetic heating roller is a development trend of heating roller, which is rapidly replacing and eliminating the original heating method. The above is the comparison between the electromagnetic heating roller, the heat conducting oil heating roller and the electric heating roller. If you want to know more, please contact us. Editor: Vivian the electromagnetic heating roller is widely used in various industries, especially in the complete set of equipment in some manufacturing industries. The electromagnetic induction heating roller is rapidly taking the heat-transfer oil heating roller with the old technology. At present, it is used in laser anti-counterfeiting printing, molding, laminated glass composite, composite film production, medical tape, aluminum-plastic plate Gluing, chemical synthetic fiber, rubber and plastic calendering and many other industries have been successfully applied, so what advantages does it have? Let's get to know each other! 1. Compared with the traditional heat conducting oil roller, the heating assembly power of the electromagnetic induction heating roller is reduced https://www.ranzhichina.com/product/detail/induction-wok-cooker-wok-induction-burner-induction-wok-stove.html by nearly 60, and even more in different industries, with significant energy-saving benefits. 2. The electromagnetic induction heating roller uses the eddy current heating method generated by high-frequency magnetic field to heat the roller, completely eliminating the environmental pollution caused by the leakage of heat-conducting medium, the rupture of oil circuit, and the evaporation of oil, greatly changing the sanitation and cleanliness of the production environment, and effectively improving the quality and competitiveness of the product. Because there is no heat transfer oil, the fire caused by heat transfer oil is avoided. 3. The electromagnetic induction heating roller adopts the uniform temperature technology, which can make the roller surface temperature uniform, and the temperature difference is controlled within ± https://www.ranzhichina.com/product/induction-cooker-3500w-commercial-induction-cooker-price-induction-cooker-manufacturer 1 ℃, so as to control the temperature andThe roller surface temperature is within ± 0.5 ℃, the temperature control system greatly improves the product quality, and the product performance is several grades higher than the similar products in the market. 4. The heating mode of electromagnetic induction heating roller is magnetic induction heating. The roller surface is not directly connected to the electrical part, and the control part has multiple protections, so it is reliable. 5. The main characteristics of the electromagnetic induction heating roller are stability. The independently developed IGBT module of electromagnetic heating can overcome the shortcomings of high failure rate under harsh environment. Good heat dissipation design and high-performance combination of components are powerful guarantee. The above is the advantages of the electromagnetic induction heating roller that I share with you.
