★★★ Efficient and energy-saving series one to two (one furnace melting and one furnace insulation) dual power supply design

Series connected intermediate frequency power supply can achieve single power supply, dual power supply, and multi power supply configurations

The new type of one to two series intermediate frequency melting furnace has the function of using a set of intermediate frequency power supply to simultaneously operate two furnace bodies. The equipment utilization rate reaches 100%. By adjusting the power knob (or digital operation screen), the total power of the intermediate frequency power supply can be distributed and used between two furnaces, achieving the effect of melting one furnace and keeping the other warm. It can achieve one-time casting of large castings or provide continuous supply of molten iron to the production line. The continuous and uninterrupted melting mode greatly improves production volume, is energy-saving and practical, and has been widely accepted and loved by customers.

★★★ Advanced computerized melting management system

The on-site smelting management computer, digital main control board, and PLC equipment form a network system. It can be controlled and managed in the office through switch expansion. Equipped with Ethernet and USB ports, as well as a unique IP address, it enables data collection, transmission, and monitoring of devices from anywhere in the world, providing remote diagnosis and quick and timely troubleshooting.  
★★★ Fully digital on-site melting control system

It can achieve automated operations such as automatic temperature control, automatic oven drying, power distribution display, intelligent melting management, and display and storage of fault information.  
This set of equipment can be fully controlled automatically, including PLC programmable controllers, HMI human-machine interfaces, industrial control computer systems, industrial control configuration software, and various sensors. It can be configured with foundry equipment and operations, and connected to various tools, including remote displays, temperature measuring instruments, thermal analyzers, spectrometers, demand controllers, and large screen displays. Safer and more convenient to use!  
★★★ Remote control console

When the intermediate frequency power cabinet is placed in the basement and the remote control console is placed on the furnace platform, other functional operations such as starting, stopping, and resetting of the intermediate frequency power supply can be achieved. The remote control panel is equipped with a large-sized touch screen, PLC, and human-machine interface to form a convenient on-site melting manager. Its functions include automatic furnace drying, cold furnace start-up, fault diagnosis, fault information display and storage, operation information display, system status display, etc.  
★★★ Fault detection (protection) display

Real time tracking and protection of running equipment in all directions. When abnormal values such as load short circuit, overcurrent, overvoltage, insufficient water pressure, and high water temperature are detected, they will be promptly fed back to the control system to achieve automatic shutdown protection and prevent accidents before they occur. In addition, damaged components such as thyristors, compensating capacitors, and voltage transformers will automatically shut down and light up corresponding indicator lights.  
2、 Characteristics of Hengyang Electric Furnace Intelligent Manufacturing

1. The design of the intermediate frequency coreless induction furnace body includes two dust removal systems: a dust hood and a dust ring  
The vacuum hood (ring) absorbs dust and exhaust gas generated during smelting through a certain amount of air flow, achieving and improving the emission effect of exhaust gas. It is designed in accordance with environmental impact assessment requirements, and users can choose the configuration according to their needs.

2. Fully intelligent automation and humanized functional design  
★ Tilting furnace oil cylinder system: including hydraulic pump station and tilting furnace operation platform. Designed for full load tilting of the furnace, it consists of a hydraulic pump and drive motor, emergency pump, motor starting device, oil tank, return oil and oil suction filtration device (with explosion-proof valve device). The tilting, stopping, and resetting of the furnace body are achieved through the buttons and handles on the hydraulic control panel. The furnace body can be tilted 95 degrees by the hydraulic cylinder, pouring out all the molten metal, and can be stopped at any position during the tilting process as needed.  
★ Automatic constant temperature function: The required range of furnace water temperature can be pre-set, and one click start can achieve automatic constant temperature; Compared to traditional manual temperature control, the automatic constant temperature function saves time and effort, is more sensitive and accurate, makes it easier to control the furnace water temperature, reduces oxidation and burning losses, and ensures even metal composition for better product quality during casting!  
★ Automatic oven drying function: Oven drying is a relatively complex and long-term curve heating process. To extend the service life of the intermediate frequency furnace and reduce production costs, the correct furnace building and drying process is crucial. Our company's innovative automatic baking function can pre-set the required time and temperature for different baking stages based on the baking temperature requirements of different refractory materials for the furnace lining; According to the pre-set time and temperature values of the PLC, one key start is used to automatically match and continuously adjust the size of the intermediate frequency power, control the heating speed, prevent cracks in the furnace lining, and achieve the goal of automatic curve baking. It not only avoids manual errors but also reduces the labor time and intensity of workers.  
★ Anti piercing furnace alarm function: Hengyang's unique dual anti piercing furnace alarm function adopts a dual combination of differential current and DC injection detection. Provided extremely reliable and comprehensive rapid protection for furnace leakage and any grounding faults in the furnace system. The detection system has an early warning function. When the furnace lining becomes thinner to a certain extent, an alarm light will be sounded in advance to remind users to pay attention to the approaching service life of the furnace lining, and to predict the furnace penetration in advance to achieve the goal of safe production. Solve the customer's problem of being unable to start up due to continuous use, and the inability to continue melting due to material in the furnace.  
★ Furnace body weighing function: According to customer needs, a weighing system can be installed in the furnace body, and the weight data of the molten iron can be transmitted to the operating platform PLC and displayed through a touch screen, which is convenient and intuitive to reflect the weight of the molten liquid in the furnace body, and facilitate the operator to adjust the composition and arrange the production volume. At the same time, the system can also achieve automatic melting. It can automatically control the weighing and transportation of furnace materials according to the formula of each brand's material list, with automatic error compensation, automatic alarm for out of tolerance, printing and recording of ingredient data, high ingredient accuracy and fast speed; Accurate ingredients ensure stable composition of molten iron, providing a strong guarantee for producing high-quality molten iron!  
★ Lining pushing out structure: Once the furnace temperature cools below 400 ℃, flip the furnace body to a 90 degree angle, lift the pushing out oil cylinder with a crane, place the oil cylinder connecting flange in the pre designed guide rail at the bottom of the furnace body, start the hydraulic pump station, and easily push out the lining. Reduced work intensity and improved work efficiency.
