Re: Surprise furnace improvement

anybody in here used a referb furnace, I'm thinking about building a new furnace, and I want it to be either a top hat, so I don't have too lift the crucible up an out, or make it a referb and tip it up and pour into one of the ladle liners that are light weight and the only thing I would have to do it hit it with a rosebud to heat it up to catch the melt for pouring, or tip straight into a mold. if only doing one mold.
opinions, comments, Pro's, Con's. one of the pro's I see is I can do the top half with fiber and make it super fast to heat up to melt temp. If I do the bottom half of a reveb right I should be able to use fiber under a hardshell melting basin or instead of fiber use the Alumina Oxide brick as an underlayment and for the insulating factor.
I don't want to do Iron in it, Actual easiest way to do Iron is in a Cupola, if your going to pour lots of it. Otherwise if your pouring over an A10 you have to have help either manual or electric hoist type.
The one big advantage to a reveb is that if built right they are continuous melters for non ferrous metals like aluminum because if you leave a heel unless your only making one pour or the last pour as you pour our molds you just keep feeding material to the furnace, dross is no problem, because its easy to just hold it back and leave it in the furnace till you clean out, or it builds up enough that you have to remove some. The Dross is a natural protective cover plus a bunch of impurity's from oil, clear coatings from car wheels and such.
Also with a referb you can set your burner up to run a lot more efficient so that in times of high fuel cost you get the most for you buck as the politicians say.
