Differentiate between core type and core less induction furnace.
|
Sr.No.
|
Core type induction furnace.
|
Core less induction furnace.
|
| 1 |
Less leakage flux
|
More leakage flux
|
| 2 |
Power factor is good
|
Power factor is poor
|
| 3 |
Works at normal frequency
|
High frequency supply is required
|
| 4 |
Weight & size is more
|
As there is no magnetic core weight & size of furnace reduces.
|
| 5 |
Design for high capacity
|
Design for low capacity
|
| 6 |
Crucible used is either Horizontal or Vertical
|
Crucible of any shape is used
|
| 7 |
Initial cost is less
|
Initial cost is more as High frequency supply is required
|
| 8 |
Used to melt only conducting metals
|
Both conducting and non-conducting charge can be heated.
|
| 9 |
Time required for heating is more as normal frequency is used.
|
Due to high frequency, high voltage supply, time required for heating is less.
