Do not heat them further and try and straighten them! This extra heat can cause work hardening of the carbon steel, causing it to become brittle, and meaning the disk could snap during use!
If you can setup a mag base and an accurate DTI on the disk, and it's not running out too much, you may be able to straighten it somewhat through a bit of brute force and ignorance. I personally wouldn't do that either, and it depends entirely exactly how bad they are, but I've seen it done (this could arguably also weaken the disk).
The easy answer, as said above, is to take it to a machine shop and have them turn it down on a lathe or milling machine, I've never heard of it being done to bike disks though, simply because they are so thin to start, I would imagine its impractical to do it without reaching the service limit.
The only practical solution, is to replace the disk(s). Or just don't use your brake anymore :lol
