【SCR——series】
Full - controlled rectifier, SCR half - bridge series inverter. The whole smelting cycle can obtain very high power factor, upper harmonic less. Simple operation, friendly and clear man-machine interface, can realize automatic smelting. It can achieve signal output, multi-track. Matching molding line, high casting efficiency can be obtained.
Inverter power：100KW-16000KW
Furnace：0.1T-30T
1. High power equipment, according to the actual need to select 12 pulse or 24 pulse structure, the upper harmonic are less.
2. The controllable full-bridge rectifier system detects the working current of each rectifier bridge in real time and adjusts it in real time. The current of each rectifier bridge is balanced and the unbalance degree is less than 5%.
3. Adopt the mode of frequency modulation and power regulation, adopt high-end fast thyristor, the maximum power output can be obtained by starting the machine. Under standard test conditions, the melting time of standard equipment is as low as 42 minutes, and the power consumption is as low as 500KWH/T per ton.
4. each furnace power stepless regulation, power can be in rated power 2%-100% operation.
5. The transformer is always in full load operation. Under the same power load, the output is 20% higher than signal output equipment.
6. Real-time parameter detection of 20 items to ensure stable operation of equipment
【SCR -- Parallel 】
Adopt full control rectifier, SCR full bridge parallel inverter. Rectifier voltage and power regulation, constant inverter frequency.
Inverter power: 100KW-45000KW
Furnace：0.1T-100T
1. according to the power requirements, select 12 or 24 pulse rectifier.
2. Sweep-frequency soft starting, don’t need independent starting device, simple debugging and operation.
3. All trigger pulses are transmitted by optical fiber, stable and reliable.
4. Multiple groups of SCRS are combined in series with a unique current and pressure balancing structure, which can reduce energy consumption and effectively avoid device overload failure.

Power per module: 750KW
Frequency: 150-1000Hz
Power factor: inverter series resonant design, fully open rectifier≥0.96
Rectifier mode is 12 pulse or 24 pulse structure, the upper harmonics are less.
Combined power: 0.25-18MW
Energy consumption, stability, are not lower than international brands.
Modular structure, convenient combination, simple line, high reliability
The inverter components adopt asymmetric SCR, which has short turn-off time and low power consumption;
The power utilization rate of the equipment is close to 100%
Each furnace adopts independent control system
The opening diameter of the crucible is 20-30% larger, so that the casting factory can use a larger and heavier (usually cheaper price) material.
Ferrous/non-ferrous metals smelting and casting.
