Description
Welding preheat and
heat treatment induction heating machine
AtecF 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.
AtecF 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 *0 years, no brass jams.
No polarity filter capacitor design life of *0 years (electrolytic
capacitors less than 5 years).
The parameter setting online functions.
