目前印刷行业与塑料橡胶行业普遍实用的加热辊有以下两种：电加热管加热辊与油加热辊，电加热管加热辊构造是由内部电加热管排布而组成。而油加热辊是由一个油站与一条输油管道组成，而油站内又装有加热管，此两种加热辊在生产中存在以下几种问题：
1、辊面温差大。
2、加热功率过大，热效率低，耗电率太大。
3、不能根据生产工艺改变加热辊上的温度曲线。
4、温度精度低，由于辊面温度太大温度仪无法及时的采集与控制到，所以就无法保证产品的质量。
5、电热管是易损器件，导热油又需要定期更换与清理所以维护成本过高。
6、操作简单方便,跟同类的电磁加热辊相比，此加热辊操作更加的智能。
7、工作稳定性高。
株洲齐杰科技有限公司制造的电磁加热辊（电磁感应加热辊）将是替代电加热辊与油加热辊的必然趋势，电磁加热辊节能环保、智能操作、安全可靠，适合在纺织、造纸、复合、印刷、压延等行业应用。本公司生产的电磁加热辊温度可在室温—500℃可调，辊面温度均匀度可做到±1.5℃，控制精度可做到±0.1℃
English Introduction:
At present, there are the following two printing industry and plastic and rubber industry, general and practical heating roller: electric heating tube heating and heating oil roller, the electric heating tube heating roller structure is by the internal electric heating tube arrangement and composition. The oil heating roller is made up of an oil station and an oil pipeline, and the oil station is equipped with a heating pipe, and the two kinds of heating rollers have the following problems in production:
1.the temperature difference between the roll surface.
2.the heating power is too big, the thermal efficiency is low, the power consumption is too big.
3.not according to the production process to change the temperature curve on the heating roller.
4.the temperature accuracy is low, because the roll surface temperature is too big temperature meter can not collect and control in time, therefore can not guarantee the product quality.
5.electric heat pipe is a vulnerable device, heat conduction oil and need to replace and clean up the regular maintenance costs are too high.
6.the operation is simple and convenient, compared with the same type of electromagnetic heating, this heating roller operation more intelligent.
7.high work stability.
Zhuzhou Qi Jie Technology Co., Ltd., manufacturing of electromagnetic induction heating roller (electromagnetic induction heating roller) will be the substitute for the inevitable trend of the electric heating and heating oil and, electromagnetic heating and energy-saving environmental protection, intelligent operation, safe and reliable, suitable for applications in the textile, paper, composite, printing, rolling, etc. industry.The temperature of the electromagnetic heating roll can be adjusted at room temperature and 500, and the temperature uniformity of the roll surface can be controlled at 1.5, and the control precision can be 0.1.
