OK, I'm on to building the Tempering Oven
I found a donor hot plate thing, it draws 1200 watts max, so should do nicely, it was $12 delivered to my door, I promptly cut it up in to pieces
I took two bricks, and stagger jointed the edges together, then I carved out a depression for the hot plate to sit in, with two holes going right through the bricks for the wiring.
I then built up a mock up of an oven around this hotplate thing, hooked it up and let it rip!
It took about 8 minutes to get to 600C...........
I slid one top brick aside to take a look see, yep, it's hot!
The one problem I'm seeing is the temp control on this unit is not very good, I ran it through a good dozen cycles and the low point where the heater kicks back on and the high point where it kicks off is about 80C different........ not so good.
I need to hit a temp between 540-570C for 62 minutes, according to the steel maker.
I guess I'l try to find some kind of controller that is more sensitive?
Any ideas guys?
