It's a chamfer ring which sits on top of the top bearing cap.

I'll use lots of GT85 on it then hot water, push down the steerer with a handle bar attached to a stem and it sh should come off.

Resist the urge to hammer the steerer even with a sacrificial top cap, it might deform the top of the steerer and makes the headset removal even more difficult.

I learnt this the hard way. I think it should be fine with a rubber mallet though (plus the oil and hot water you mentioned)

Same here... ended up having to saw off the topcap and bit of steerer which were pretty the distortred and wedged in.

Another way is to use a heat set crown race setter, couple of knocks frees it and inertia will do the rest.
