Any idea about 3-6kw PSU in the 48-60VDC range to power 2500-5000W ZVS induction heat

Depends on the material. Some could have such a heat treating curve, that this method is impossible or impossible to control. But according to this study, the exact steel i will be using even benefits much from using that method.

Normally the makers will use 15-40kw induction to forge meta, quick heat to temperatures for hammering it.

The study you link to used conventional heating to normalize the material. They quote a time of 30 minutes at 870 °C but don't mention the cooling down rate or time.

The material comes annealed and i will machine it, so no stress here. Its oil quenched, oil at 40C

Go for it but there is a big difference between annealing and normalizing.
