Anyang STF High-frequency Induction Forge

Brief introduction of Induction Forge

Induction heating furnaces are novel heating equipment operating on the principle of electromagnetic induction, widely employed in industrial production and metalworking.

Their core mechanism of Induction Forge

Their core mechanism involves an alternating current passing through an induction coil to generate an alternating magnetic field. When a metal workpiece is placed within this field, eddy currents are induced within it, causing rapid heating. This achieves the effect of ‘electromagnetic heat generation through non-contact heating’.

Advantages of the Induction Forge

Compared to conventional heating methods, it offers significant advantages: rapid heating speeds substantially shorten production cycles; high thermal efficiency with energy consumption reduced to 50%-70% of traditional equipment, delivering energy savings and environmental benefits; uniform heating minimises workpiece deformation, ensuring machining precision; and the absence of open flames or fumes creates a safer, cleaner working environment.

Classification of the Induction Forge

Classified by frequency, they are categorised into three types: Industrial frequency furnaces suit large-scale steel and cast iron melting; medium-frequency furnaces are predominantly used for non-ferrous metal melting and metal heat treatment; while high-frequency induction forge are ideal for precision processing such as small-part quenching and welding.

High-frequency induction forge applied for blacksmithing

High-frequency induction forge / furnace are precision heating equipment operating on the principle of electromagnetic induction, with core frequencies typically ranging from 10kHz to 500kHz.

Core Characteristics of High-frequency induction forge

1, Heating occurs at an exceptionally rapid pace, achieving target temperatures within seconds to tens of seconds, with thermal efficiency exceeding 80%.
2, Heating is concentrated on the workpiece surface, achieving a ‘hard surface, tough core’ effect without open flames or pollution.
3, High temperature control precision allows precise adjustment of power and heating duration, minimising workpiece deformation.

Applications in the blacksmithing shop.

It is precisely because the high-frequency induction heating furnace has the above characteristics that it is particularly suitable for heating iron. The forging workpieces in most ironwork shops are of slender or thin dimensions. Such workpieces are particularly suitable for heating with a high-frequency furnace, as they can be rapidly heated to the surface and completely heated through quickly.

Anyang STF series High-frequency induction forge core electronics supplied by Siemens, Schneider etc, famous brands to ensure the high reliability. And the induction forge integrates a high-quality chiller to offer a reliable cooling function. The compressor in this chiller is of the Panasonic brand. Using R410A refrigerant is safe and reliable.

Induction forge parameter

This series of high-frequency heating furnaces is suitable for applications including hot forging, welding, heat treatment, and smelting.

1. Hot Forging Range:
The heating time decide the heating depth and temperature. Heating commences from the piece
surface. For instance, the 15kW model can heat solid bar 5-30mm , and the 25kW one can heat
solid bar 5-50mm. If heating a 15mm solid copper rod to 1000°C requires 6 seconds with 15kW, but 25kW just need in 3 seconds.

2. Welding Range:
The induction forge can heat up Silver-based solder to be 700-850°C, while copper-based solder
demands 900-950°C in 25-30 seconds.

3.Heat Treatment:
According to adjust the output current and duration parameters, the temperature can reach up to
approximately 2000°C.

4. Melting:
When used in conjunction with a crucible, it enables the smelting of various metals.
