Stumped, shower base plumbing connection to pipe
My house was built by a bunch of @#$%&, so I'm always running into things that make no sense. Now I've come across something that I have no experience with and it has me a bit stumped. I removed my existing shower base. I had to cut around the drain since I was not sure how that attached to the plumbing beneath. Once cleared, I have a big hole in my slab, what looks like an uneven inner pipe (as if they just busted off the excess), and what looks like a sleeve that was on the top side of the base that fits over the pipe. Is this sleeve screwed on, or pressed on?

Shows where I am at right now, with the hole in my slab.
As I'm sure you know, it is the silver piece that I am trying to remove

The lip of it is only about an inch above the surface of the slab. You can see the jagged edge of what looks like cast iron pipe.

The pic is a little blurry due to the camera's proximity to the pipe... that's as far as I can get from it with the camera beneath the slab.
Any suggestions on how to remove it? I've put some liquid wrench on it, and heat. But since I don't know if it is threaded or not I'm a little reluctant to start putting a lot of force on it. If it's threaded, I'll have to come up with some device to unscrew it.
Thanks,
