Welding preheat and heat treatment induction heating machine
SFWH series medium frequency induction heating machine is for preheat and post weld heat treatment to help welding large workpiece:
The welding temperature of Large workpiece has a more stringent process control procedures, general requirements for heating to a certain temperature, welding, heat treatment after welding is completed, the rate of its heating and cooling also has strict requirements.
SFWH series medium frequency induction heating machine can be set to store a number of technology curve, using sub-timed run, and in the constant temperature closed-loop operation mode to achieve the above technical requirements, can reach a certain rate of warming, a certain rate of cooling, keep temperature and other functions.
Thermocouple temperature measurements can be used, infrared temperature measurement and other means.
Supporting DTR-U data record controller, with multi-point temperature display and control ability, and the realization of the actual temperature curve recorded.
Unique synchronization technology, multiple equipments can heat one workpiece at the same time, even if the sensor is adjacent, undisturbed, and the temperature can be controlled independently.
With the sensor leakage protection.
IGBT inverter, compared to SCR devices, the efficiency and the power factor are improved significantly.
Rated Power continuous operation design, system failure rate is low, no water system failure.
A variety of control methods and a rich interface, easy to realize automatic control.
Precise control of the DSP, the frequency of automatic tracking, ensure that devices work in the best resonant state; and if the grid voltage fluctuated, the output power will remain unchanged.
Fully functional and reliable protection limit, short circuit in the sensor, workpiece short-circuit, overload operation, grid abnormal fluctuations, the power equipment will not be damaged.
Output transformer isolation, the sensor voltage is low, and can be single-grounded.
Air-cooled transformer design life of 10 years, no brass jams.
No polarity filter capacitor design life of 10 years (electrolytic capacitors less than 5 years).
The parameter setting online functions.
