Introduction
Why the Induction Heating?
Controlled features
Energy conservation
Non-contact heating
Environmentally friendly
Clean heating
Increase production line speeds
Application
Industrial application
Housing applications
Medical application (precision induction heating)
Project goalsbuild and formulate a basic knowledge about
induction heating .
deal with the industry requirements for simplicity ,saving the power consumption, clean heating and fast productivity.
To build a model for induction surface hardening machine.
Carry out some testing on the model.
Design criteria There are two serious problems especially become important
when the material starts heating up.
