Comparative advantage of electromagnetic heating roller and oil heating roller
Now on the market for the heating roller and the double wall, in order to make the roller temperature forced to reach our work needed temperature uniformity, in the design of roller with inner and outer wall welded into the container to form a hollow shape into the heat conducting oil, and in the heating process by reaching a uniform temperature boiling heat conducting oil this design, will have the following disadvantages:
1. in the work, the boiling heat of the heat conducting oil generates great pressure inside the roller, so the heat conducting oil exudates through the part of the welding part and the oil inlet and the material density of the roller body, resulting in environmental disqualification, and the smell of oil pollution in the workshop is serious. At the same time, the oil heating roller also has the problem of heat conduction oil carbonization, which causes the disadvantages of inconvenient maintenance and high energy consumption.
Heat conducting oil is
2. by boiling oil formed after the flow of high temperature and low temperature oil oil mixture flow so as to achieve uniform, and the heat conducting oil selection need to choose according to temperature, when we need to put forward 300 roller manufacturer roller temperature, manufacturers will choose oil 260 the boiling point of 280 degrees into the roller and in our reality, in the production of 300 degrees for what we need most upper temperature, so the production line we will put a set temperature of roller according to our production requirements set the temperature gradient, let the product line into the gradient heating, when we set the temperature below the boiling point temperature of heat roller at the effect of heat insulation, heat conduction oil will reverse the roll inside, will bring us the heating roller to roll interior design reflect the outer wall, so as to reach more roller The temperature uniformity we need.
The 3. interlayer thermal oil roller, control response cycle is very slow, the control precision is very low, because the flow and heat conducting oil will make the floating roller control instrument control is particularly large, especially in several roller combinations, each roller floating control is too large, can not form a regular, so in the end part can not adjust the temperature. Garbled.
Comprehensive analysis of the above analysis of our Zhuzhou Qi Jie Technology Co., Ltd. electromagnetic heating roller has the following characteristics:
1., the electromagnetic heating roller does not need heat conduction medium such as heat conducting oil or steam, and completely eliminates the pollution and safety hidden trouble caused by leakage, leakage and volatilization of the medium, so as to truly realize pollution-free and dust-free cleaner production. Compared with the traditional oil heating roller, the power saving rate of the electromagnetic heating roller is over 60%. The complex heating equipment and pipeline facilities are abandoned, and the energy consumption of heating is greatly reduced.
2. our electromagnetic heating roller roller with single wall roller, simple structure, the substrate modified by embedding conductive materials into the oxidation, solid heat conducting materials, so because of the characteristics of its structure and excellent performance, breaking the bottleneck of traditional temperature heat conducting oil, and to reach within plus or minus 1.5 DEG C temperature the effective working roller surface, satisfy the temperature requirements of the high performance materials, both high temperature high temperature metal composite film or PTFE and all kinds of material can be easily done.
3.the structure of the electromagnetic heating roller is controlled by the temperature and the reaction cycle is fast. We can flexibly adjust the curves and gradients needed in the production process according to the control temperature of the partition process of the special process, so as to ensure the material quality.
Our electromagnetic heating control inverter is made by our own R & D and design + production debugging. It can achieve the one to one matching design and work in the manufacture and commissioning of the roller, and it can effectively ensure the stability of the roller in the work. The electromagnetic heating roller temperature curve according to our customers in the production line of steel preheating walking through the temperature sensor to collect the strip in the composite roll before the feedback to the PLC interface to control the temperature curve of height adjustment, and realize that we need in the production process of temperature uniformity and curve adjustment.
