The general traditional coil design is prone to the following problems:
1, the coil is deformed, so that the lining cannot be pushed out normally;
2, the coil strength is not enough, and the deformation is serious, especially in the middle part;
3, the coil insulation is not enough, and the coil turns short circuit frequently;
The coil design of the new research industry eliminates the above defects and provides customers with stronger, more reliable and more durable coils. Open steel structure, convenient for daily maintenance and overhaul. Large H-beam or square steel tube constitutes the basic structure of the furnace frame, and the overall structure is simple and firm.
Comprises an open furnace body, a furnace frame, a furnace cover, a furnace tilting oil cylinder, a furnace cover lifting device, a rotary oil cylinder, an inductor, a yoke, a high-pressure carbonless rubber hose, a fixed material poured at the furnace mouth and the furnace bottom, a complete set of stainless steel water inlet distributors, a backwater collector, a fixture and the like. , including wall-mounted water separator. Water glycol is used as the hydraulic medium in the cylinder design.
Refractory materials are knotted on the surface of the hearth to fully protect the furnace body and prevent the hearth from deformation. The application of computer aided design in induction melting ensures the accuracy of coil parameters and a wide load matching range.
Digital control circuit and signal transmission are all realized by optical fiber, which has strong anti-interference ability and more stable system.
12 pulse trigger board, automatic current balance. Realize soft start and prevent the impact on power supply. As a fast electronic switch, cut off the power supply when there is a fault.
A series resonant double-output power cabinet and two furnaces form a smelting system with one electric furnace and two furnaces, and the output power can be distributed between the two furnaces at any time, and the two furnaces can supply power at the same time, and one furnace is insulated and the other furnace is smelted.
The rectifier part of the power cabinet is fully open, so the power factor is high and the higher harmonics are small.
The power supply is equipped with a stable and reliable molten iron leakage protection device combining differential current mode and DC injection mode. Meanwhile, the power cabinet is equipped with a melting manager. PLC and man-machine interface constitute a convenient melting manager, whose functions include: automatic oven drying, cold oven starting, fault diagnosis, fault information display and storage, operation information display, system status display and so on.
