An induction furnace can (does!) induce a strong circulating current in the
melt and this can make the melt swirl - I assume the button is altering the
induction driver to maximise this effect.
You want an Induction Furnace? I have one that I haven't re-commissioned
since moving here a few years ago - I'm sure we can negotiate a deal :)
Mark, I did have a 160 amp per phase three phase 415v supply run in
specifically for the furnace but other projects keep popping up and stopping
me. I even had a fire proof building put up for it, then it got filled with
other stuff ! Hopefully it'll get to the top of the list before they put me
in a nursing home!
Sounds like a big piece of kit, maybe like one put in near me many years
ago where the company had to have a new big electric feed put in for the
induction furnace. I've only seen a couple of other induction
heaters/melters, one was in Norfolk and the guy used it for silver
soldering some medical gas regulator parts and IIRC old enough to use
valves but still worked well for the job but a big beast. The other was
in the QC lab at Hoesch steel in Dortmund Germany and was used to melt
and cast samples for optical emission analysis of the steel, no idea of
the internals but it cast a piece you could hold in your hand and was
about the size of a standard 3 drawer filing cabinet.
It's 100 kW and all semiconductor :)
Comes with two 'furnace bodies' that look like concrete mixers. One is a
conventional tilt for for pouring into a ladle or direct to the mould, the
other is an 'invert' type where the mould is clamped to the top of the
furnace body and the whole thing inverts dumping the charge into the mould.
