400-500KW Intermediate Frequency Induction Forging System

Intermediate frequency heating furnace is induction heating equipment for the purpose of heating metal forging or tempering heat treatment.

It is generally used for heating before forging and the heating temperature is 1200 degrees, while the heating temperature for tempering heating is generally within 1000 degrees. This intermediate frequency heating application determines that the heating principle of an intermediate frequency heating furnace is only for heating purposes and cannot melt metal.

Intermediate frequency furnace is mainly composed of variable frequency device and induction coil, power frequency 50 Hz alternating current frequency conversion device would turn into intermediate frequency 100 Hz – 10000 Hz of alternating current, the three-phase alternating current into direct current (dc) after rectifying power frequency, and then laid adjustable intermediate frequency electric current, direct current supply by the capacitor and inductor in the flow of intermediate frequency alternating current, generate high-density magnetic field lines in the induction coil, induction coil, and cutting in cheng fang of metal materials, produce a lot of eddy current in the metal materials.

The frequency conversion device and induction coil of the intermediate frequency heating furnace make the heated metal material produce eddy current, which also has some properties of the intermediate frequency current, that is, the free electrons of the metal itself flow in the metal body with resistance to produce heat., for example, put a metal cylinder has alternating medium frequency current in the induction coil, the metal cylinder has no direct contact with an induction coil, electric coil temperature is very low, but the surfaces are heated to redness, and even melt, and the redness and melting speed as long as adjust the size and the strength of the current frequency can be achieved.

If the cylinder is placed in the center of the coil, the temperature around the cylinder is the same, and the heating and melting of the cylinder do not produce harmful gases or light pollution to the environment.

The frequency range is wide, from 1 kHz to 20 kHz, and the appropriate frequency can be selected according to the specific diameter of the heated workpiece.

The induction coil is 500mm-1m long when the whole material is heated by medium frequency forging furnace, and multiple materials are heated at the same time, which further ensures the heat penetration effect.

The intermediate frequency forging furnace adopts continuous heating mode, and the load inside the induction coil is relatively balanced, which overcomes the huge change of the actual heating power of the equipment caused by the huge change of the load when the load of a singlebar rises from room temperature to 1100°C in the whole heating process, so that the actual power of the equipment can be guaranteed to be above 85% of the rated power value in the whole continuous heating process, and the equipment can be effectively utilized.

When heating nonferrous metals such as copper and aluminum, the actual power of the equipment can also reach more than 85% of the maximum power by reasonably designing the induction coil and capacitor, and the heating capacity can reach 3.5 kg/kW hour when heating copper.
