High Power Output Induction Heating

The ROCHO medium-frequency induction heating power supply utilizes advanced all-solid-state IGBT frequency conversion technology with power regulation functionality. Its constant power output ensures maximum utilization of the power transformer, while a parallel resonant circuit, digital phase lock technology, and automatic frequency tracking adaptation ensure high power efficiency and an extremely high-power factor across the full range of power outputs. This results in a more stable and uniform heating experience, providing greater consistency and efficiency in heating applications.

Versatile& Flexible Frequency Configuration

Our medium-frequency induction heating power supplies are available in a range of power outputs and can be matched with frequencies from 1kHz to 10kHz, ensuring flexibility to meet the specific needs of our customers. Our team of engineers takes into account various factors such as heating depth, efficiency, and location to design the most suitable working frequency range, resulting in optimal heating effects.

These versatile power supplies are particularly useful for deep heating of metal workpieces, including hardening of large parts, hot forging of bars, metal melting, full tempering of dies, and preheating before welding.

Comprehensive Protection Features

ROCHO medium-frequency induction heating power supplies are equipped with multiple protection functions, including over-current, water shortage, over-heat, over-voltage, short-circuit, phase failure/loss protection, and other alarm functions. These features automatically trigger alarms in case of faults, greatly improving the reliability of the equipment.

The display screen provides various data, including current, voltage, and time displays, allowing for easy visualization of the equipment's working conditions.

The medium-frequency induction heating power supply can be equipped with infrared thermometer to realize automatic temperature control and improve heating quality along with temperature control accuracy.

The medium-frequency induction heating power supplies can be equipped with a PLC control system, allowing for seamless integration with the flow process of an automatic production line.

The medium-frequency induction heating power supplies can be equipped with a fully enclosed internal circulation water cooling system. If the water temperature exceeds safe operating limits, the induction heater automatically triggers an alarm and stops operation, ensuring the safety and reliability of the equipment.

Sustainable Eco-Friendly Induction Heating

The medium-frequency induction heating power supplies provide fast melting speeds, high efficiency, and reduced combustion of material elements when used for melting non-magnetic materials such as stainless steel, copper, industrial silicon, and aluminum. This results in less waste of raw materials and reduced costs compared to traditional heating methods. Additionally, our power supplies offer advantages such as higher efficiency, less pollution, and lower energy consumption, resulting in energy savings of over 20%. This not only promotes a healthier and improved working environment but also enhances the company's image and enables a non-polluting production process with lower energy consumption.

Applications:

Our medium-frequency induction heating power supply is highly efficient, fast, precise, and suitable for automatic production. It is widely used in various industries including smelting, forging, pipe bending, and surface heat treatment. It excels in diathermanous forging applications such as heating forging of bolts and nuts, local heating of steel bars, and hot forging of railway accessories.

Additionally, it can provide hardening heat treatment for automobile parts like gears, shafts, and crankshafts, as well as weld preheating and post-weld tempering.
