Question

Compare Core Type Induction Furnace with Core-less Type Induction Furnace.​

Answer 1

Answer:

Explanation:

Core type induction furnace\

1 Less leakage flux

2 Power factor is good

3 Works at normal frequency

4 Weight & size is more

5 Design for high capacity

6 Crucible used is either Horizontal or Vertical

7 Initial cost is less

8 Used to melt only conducting metals

9 Time required for heating is more as normal frequency is used.

Core less induction furnace.

1 More leakage flux

2 Power factor is poor

3 High frequency supply is required

4 As there is no magnetic core weight & size of the furnace reduces.

5 Design for low capacity

6 Crucible of any shape is used

7 Initial cost is more as High-frequency supply is required

8 Both conducting and non-conducting charges can be heated.

9 Due to high frequency, high voltage supply, the time required for heating is less.
