your annealing process is for wrong metal. Copper is annealed at 700-800C
(can be done as low as just over 400C, but you have to hold it at that
temperature for a long time). There is no state change on cooling copper,
so quenching is not required -- you can cool it over as long a period as
you like. The annealing process for copper is reversed by flexing and
vibration, not by slow cooling.

I'm not sure about your terminology or where the last sentence
comes in, but heating to red hot and quenching is fine.
