What is the basic principle of induction heating?
An induction heater consists of an electromagnet and an electronic oscillator that passes a high-frequency alternating current (AC) through the electromagnet. The rapidly alternating magnetic field penetrates the object, generating electric currents inside the conductor, called eddy currents.
What are the limitations for induction treatment process?
Limitations of Induction Hardening In other cases, the engineering benefits of the process may outweigh cost concerns. Otherwise, for low volume projects the coil and tooling cost usually makes the process impractical if a new coil must be built. The part must also be supported in some manner during the treatment.
Which of the following heating method is based on the transformer principle?
The innovative induction heating technology is based on principle of transformer. Electrolyte solution acts as the secondary circuit of a transformer for the heating.
What are the advantages of heat energy?
The advantages of heat, or geothermal energy, seem to be thus: The energy itself is environmentally friendly due to the source – it’s natural. It’s renewable, much like wind or gravity energy would be. It’s cheaper than most other energy forms to make as well as being more efficient at its job of heating things.
What are the advantages of heat treatment process?
Benefits of Heat Treatment in a Nutshell
- More durable product.
- Steel becomes tougher, stronger.
- Easier to weld.
- Becomes more flexible.
- Increases its wear-resistance.
- Increase in overall lifetime of the part.
What type of heating is induction heating?
The Induction Heating Process Induction heating is similar to the Joule Heating Effect, but with one important modification. The currents that heat the material are induced by means of electromagnetic induction; it is a noncontact heating process.
What metals can be heated by induction?
Which metals can be heated using induction?
- Copper and copper alloys.
- Brass.
- Aluminum.
- Iron.
- Steel and stainless steel.
- Tungsten.
- Chrome.
- Nickel and nickel alloys.
What are the advantages of heat treatment processes?
What are the advantages of high-frequency heating Mcq?
What are the advantages of High-frequency heating? The operation of high- frequency heating is simple to control.
Which of the following is advantage of eddy current heating?
(1) It is quick, and clear. (2) There is little wastage of heat as heat is produced in the body to be heated up directly. (3) Temperature control is easy i.e. by controlling the supply frequency and flux density. (4) The heat can be made to penetrate into the metal surface to any desired depth.
