1. The biggest problem in the application of heat-conducting oil-electric heating roller in the production line is: for the heating temperature above 250℃, heat-conducting oil cannot be done, but can only be used for less than 200℃, and there are oil leakage, carbonization and safety problems, which are not optional;
2. The electric heating roller can reach more than 250℃, even the highest temperature can reach 400℃, its disadvantages: low temperature uniformity, generally more than ±10℃;
3. Great error in the temperature detection, control, detection means has two kinds: one kind of measuring roll temperature inside the space, and roll surface temperature difference is very big (according to the different temperature and product difference, 40-100 ℃ temperature difference) and roll surface temperature change can not be detected, basically belongs to the state of open loop control, temperature control can't meet the production requirements;
Another test roller surface temperature, contact and non - contact temperature measurement. The contact type is that the contact element is attached to the surface of the roll (not the working surface), which has wear on the surface of the roll and the detection element, and has a low life, which affects the quality and appearance of the surface of the roll, and cannot directly detect the temperature of the working surface. The non-contact temperature measurement is greatly affected by the environment temperature, and the measurement error is large, so it is difficult to meet the production process requirements of top companies.
The heating element of 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 requirements, such as corrugated paper, non-woven fabric and so on, which basically belongs to the non-optional range.
4. Electromagnetic heating roller is now a heating roller development trend, is rapidly replacing and eliminating the original heating way. Our company is the first domestic research and development, production of electromagnetic heating roller enterprises, applied for a number of electromagnetic heating roller patents, with independent intellectual property rights and proprietary technology, compared with other companies' products more intelligent and safe, energy saving and environmental protection, at the same time, low maintenance cost, fewer faults, long service life.
Thanks to the efforts of technicians, our electromagnetic heating roller has successfully broken through the high temperature of 500℃, with its surface temperature uniformity of ±1℃ and temperature control accuracy of ±0.1℃, and its long-term stable and reliable performance, which can improve the output and quality of customers' products. The company has been adhering to the "product quality as the life of the enterprise, as the development of science and technology as the soul of the enterprise" purpose, for the company to become the leading force in the industry and struggle!
