preheating and post-heating application

full air-cool syestem of device and coil. For applications as pipeline preheating and post heating, metal heat treatment, steel flat heat treatmentdifferent type of coil. Different coils are designed for work piece shape. They range from band, special frame, flexible cable. 1-6 points for temperature display and control. ( device supplies DTR-U digital recorder) It takes the maximum point when increasing temperature, and takes the minimum point when decreasing temperature.heating treatment curves setting. 16 different heating treatment curves can be set and instored for applications by constant teperature run or constant current run.constant temperature rate control. The device can increase the temperature with constant rate, also has functions as time setting, all digital control. The temperature control accuracy ranges in ±1°C, resolution ±0.1°C. So the different parts of work piece has rare temperature difference. Heating treatment curves are stably achieved.complete events protection and warning. The device has short-circuirt protection, leaking protection, over temperature protection, over frequency protection, and other functional protection and etc.run without stop. The device  can be run wtihoout stop and keep high efficiency.heating treatment temperature over curie point. preheating temperature ranges  from 50-350°C, postheating temperature ranges 300-1200°C
