Correct Answer - Option 1 : 0.70 and 0.85
Ajax Wyatt Induction Furnace:
- It is an improved form of vertical core type induction furnace is Ajax Wyatt furnace.
- This furnace is very suitable for continuous operation, and it can be operated on standard supply frequency i.e., 50 Hz.
- The core is made of laminated steel, and the single turn of molten metal forms the secondary circuit.
- Its efficiency is about 75 percent. Standard sizes of these furnaces are 60 — 300 KW, single phase 50 Hz working at 600 volts
Advantages:
- Control is simple.
- It provides an ideal working condition in a cool atmosphere with no dirt, noise, or smoke.
- High power factor 0.7 to 0.85 comparatively
- The absence of crucible.
- The uniform stirring of charge gives the homogeneous composition.
Applications:
Ajax Wyatt Vertical Core Furnace is used for melting and refining of non-ferrous metals like brass, copper, and zinc volts.
