Any thoughts on temperature control? Heat treating requires accurate temp control and temp ramping.

You can use a PI(D) controller and pulse-skipping or phase control to regulate the workpiece temperature (pulse-skipping uses a low-frequency interrupter synchronized with the zero crossings of the current waveform, phase control phase-shifts the two legs of the bridge to control power).
