Hello!

Im thinking of building a induction furnace of about 2,5 kW! The electronics seem to be very simple to build! With a vacuum pump and a good chamber it should be possible to cheaply and cleanly melt just about every kind of metal or to make perfectly homogenuos alloys

How would you solve the pouring in the closed chamber? I was thinking of using a solenoid to "pull the plug" in the bottom of the crucible. It would take much space to tilt the crucible and harder to get the pour in the right place

What kind of refractory should i use to be able to melt higher temperature metals? How high vacuum would i need? Will i need flux? What material should i use for crucible?
