Detailde


KGPS Constant power thyristor medium-frequency power is mainly composed of 3-phase in power supply, regulator, phase-shifting control, protect circuit, phase sequence adaptive circuit, start calculation circuit, inverter frequency tracking, inverter pulse forming circuit, pulse amplifier, pulse transformer.
The core components adopt the large-scale dedicated PLC integrated circuits, the whole circuit in addition to the regulator all realized the digitalization control, the rectifier trigger section does not need to adjust, with high pulse symmetry, high anti-interference ability and fast response features.


Advantage:

1. Constant power control system is used for power control of various metal melting, heat preservation and induction heating equipment. This technology has reached the domestic leading level.
2. The control circuit is integrated, the anti-interference is strong, the peripheral circuit is simple, the performance is reliable,and the debugging is easy.
3, perfect protection function, control circuit functions such as cutoff, interception, overvoltage, overcurrent, water pressure protection.
4. Three-phase full-bridge rectification and DC superposition method are adopted to improve the output voltage, reduce the high-order harmonics, and have less interference to the power grid. At the same time, the transformer has small heat generation and low loss.
5, high power factor, low harmonic interference. The power factor of the whole machine is ≥0.98, no additional equipment is needed, which reduces the investment cost.
6, the panel mechanism is simple, internal intelligent control, easy to operate, stable and reliable performance, low failure rate, convenient maintenance, etc., greatly reducing maintenance costs.
7. Support one machine or multiple furnaces to run at the same time, with high safety performance.
8, the power can be adjusted infinitely, the operation is flexible and convenient, the frequency can be selected;
9. The whole machine is small in size, small in area, high in efficiency, low in energy consumption, and simple and beautiful in line.
10, high startup success rate, adapt to frequent start-up requirements, any load state can be started 100%, with high load adaptability: high-power factor output can be fully loaded even in the state of the freezing furnace (cold furnace)
11, the operation process is simple, get started quickly.

Equipment components:

The main components of the intermediate frequency furnace power cabinet are: main switch, rectifying thyristor, inverter thyristor, main control board, and smoothing reactor. The main control board is equivalent to the human brain and is very important. The thyristor is the core of the  power supply, and its accurate use is critical to the operation of the entire equipment.

Application:

1. Smelting of non-ferrous metals, mainly used in the melting of ferrous metals such as molten steel, alloy steel, special steel, cast iron, and non-ferrous materials such as stainless steel and zinc;
2. It is used for the smelting and heating of copper, aluminum and other non-ferrous metals.
3, metal forging heating, such as for bar, round steel, square steel, steel plate through heat, temperature, blue quenching material online heating, local heating.
4, metal materials online forging (such as gears, semi-shaft connecting rods, bearings and other precision forging), extrusion, hot rolling, pre-shear heating, spray heating, thermal assembly and metal materials overall quenching, annealing, tempering Wait.
5. Heat treatment and quenching production line: mainly for shafts (straight shaft, variable diameter shaft, camshaft, crankshaft, gear shaft, etc.); gears; sleeves, rings, discs; machine tool screws; guide rails; plane; ball head; Surface heat treatment of various mechanical (automobile, motorcycle) parts such as hardware tools, and overall quenching, annealing, and tempering of metal materials.
