1. Brief Introduction of high frequency induction heating forging
machine:
1) LSW-160 induction heating machine with IGBT series parallel
induction heating technology as the core.
2) Heating the workpiece surface and inside temperature to
approximately equal by electromagnetic induction and conduction of
heat.Introduction of induction heating/forging machine.
3) The principle is the magnetic induction heating principle.
4) Oscillation frequency selection: the larger the diameter of the
workpiece is, the lower the oscillation frequency is needed.
5) Wttage selection: the larger the diameter of the workpiece is,
or the higher the efficiency is required, the bigger wattage is
needed.

5. The working principle of Induction Heating Machine?
When a magnetic field changes near a metal or other conductive
object, a flow of current (known as an eddy current) will be
induced in the material and will generate heat. The heat generated
is proportional to the current squared multiplied by the resistance
of the material. The effects of induction are used in transformers
for converting voltages in all sorts of appliances. Most
transformers have a metallic core and will therefore have eddy
currents induced into them when in use. Transformer designers use
different techniques to prevent this as the heating is just wasted
energy. In this project we will directly make use of this heating
effect and try to maximise the heating effect produced by the eddy
currents.
6. Characteristics of induction heating Forging Furnace
1. Wide frequency range from 1KHZ to 20KHZ,frequency can be
designed to satisfy different size of the heated rods.
2. In the continuous heating process, the load inside the coil is
stable , thus to overcome the great heating power change caused by
the great change of the load during the heating course from cool
rod to 1100 degree rod. The actual power can reach more than 85% of
the rated power of the machine.
3. The heating coil can be 500mm to 1 meter long, several pieces
are heated at the same time to make sure the penetrating effect.
4. Even when heating non-ferrous metals like copper or aluminum,
the actual power can also reach more than 85% of the rated power of
the machine by design the coil properly and match the compensating
cap correctly. 3.5KG copper or brass can be heated to 700 degree
per kilowatt in an hour.
