1. Thyristors, chucking appliances and water-cooled radiators of well-known brands; all-purpose main switch with current display; copper coil of large size; 6-pulse and 12-pulse, ensuring equipment stability.

2. Design of series resonance; the rectification part of the power supply cabinet adopts a fully open design. Therefore the power factor is the highest while the higher harmonic is the lowest. It is not necessary to equip reactive power compensation and harmonic elimination devices, reducing equipment investment.

3. Digital electronic control; all trigger signals are transmitted through optical fiber, with strong capability of anti-interference; the rectification trigger board allows the current to be automatically balanced, realizing the soft start and preventing the impact on the power supply; working as fast electronic switch that cuts off the power in the event of a malfunction.

 

 

At present, the company has 3 overseas offices and over 10 partners of entrusted service. In order to better serve the foundry industry and promote the transformation and upgrading of the industry, Dingsheng has been pursuing the fine workmanship of each process and link. The company products are exported to Southeast Asia and the Middle East. In addition, there are several sets of equipment provided for Malaysia and the United Arab Emirates.

4. The layout of the power supply cabinet components is reasonable; the maintenance personnel can easily access all the maintenance points; the open structure design of electric furnace makes maintenance easy.

5. The furnace body is equipped with fall prevention device. When the furnace body tilts, the fall prevention cover is automatically raised to form a guard rail to prevent personnel from falling and to ensure the safety of the operators on the furnace platform.

6. Competitive power consumption indicator; for medium frequency smelting furnace, the power consumption per ton is ≤ 510 degrees/ton; in addition, the power supply cabinet is equipped with a smelting manager. PLC and human-machine interface constitute a smelting manager easy for operation, with functions of automatic furnace drying, furnace start under cold state, malfunction diagnosis, fault information display and storage, operation information display, system status display, etc.

 

TECHNICAL ADVANTAGES

7. Good environmental protection performance: compared with the parallel power supply, the noise of the overall unit is stable and light, which is ≤85dB measured at the position where the operating platform is two meters away from the furnace, with no noise wave; the pollution of the medium frequency harmonics to the power grid is small. The furnace body is equipped with a cyclone dust extraction hood that can work effectively in all production stages of the electric furnace, especially when the molten metal is treated. The properly flipped dust extraction hood can effectively collect dust during the process of spheroidization in front of the furnace, which is not possible with conventional dust extraction hoods.
