Description

Key Parameters of Medium-Frequency Forging Furnaces:

(1) Wide frequency range from 1kHz to 20kHz, allowing selection of optimal frequency based on the diameter of specific workpieces.
(2) During whole-piece heating, the induction coil length ranges from 500mm to 1 meter, enabling simultaneous heating of multiple bars to ensure thorough penetration.
(3) Employing continuous heating, the furnace maintains balanced load distribution within the induction coil. This overcomes significant power fluctuations caused by load variations when a single bar heats from room temperature to 1100°C, ensuring actual heating power remains above 85% of rated capacity throughout continuous operation for efficient utilization.
(4) When heating non-ferrous metals like copper and aluminum, the actual power output can also reach over 85% of maximum capacity through optimized design of the induction coil and capacitors. Copper heating achieves a capacity of 3.5 kg/kW•hour.
(5) Compared to thyristor-controlled medium-frequency systems, this design offers not only a compact footprint and easier maintenance but also delivers 15–20% greater energy savings.

Basic Components of a Medium-Frequency Forging Furnace:
Includes a medium-frequency power supply, compensation capacitor box and workbench, induction coil, and feeding mechanism. Depending on specific application requirements, it may also incorporate an infrared thermometer, temperature controller, and feeding/coil handling devices; functionality can be customized according to user specifications.

Medium-frequency forging furnaces are used for continuous through-heating of regular round bars, square bars, or other shaped blanks made of steel, stainless steel, copper, aluminum, and other materials with diameters of Φ12 or larger. They can be used for heating the entire blank or for localized heating, such as end heating or intermediate section heating.
The specific configuration is ultimately determined based on the casting process requirements of the equipment user, on-site power conditions, production targets, and scalability needs. This ensures efficient, safe, and stable operation while facilitating flexible process adjustments or future expansion.
