III. Application scope
PC steel bar has the features of high strength tenacity, low
relaxation and good weldability, and widely used for tubular pile,
viaduct pier, railway sleeper, etc.
IV. Technical features
1) Voltage/Current double closed circuit control, this mode has
constant voltage operation feature, it means the voltage of
inductors will not be influenced by Inlet voltage/Load resistor,
etc. Constant voltage make the load heating most stable.
2) The four sets of induction heating power supply unit has
features of tempeature tracking control, precise temperature
control, fast heating speed and low electricity consumption.
3) Use aluminum material sealed cabinet to realize electromagnetic
shielding and suitable for the bad environment at site.
