I'm new to the forum. So first I have had experience with some aluminum melting and casting using plaster of Paris/sand furnace. After a few good melts it's garbage.
So I'm looking to build something with a bit more life. So I live in Newfoundland, Canada and its extremely hard to find a proper refractory mix and online shipping cost is crazy for the weight. So I can easily get my hands on some wood furnace firebricks rated for 2200f to 2600f depending on vendor.
So the idea is to do a hexagon with the bricks inside a cylinder and possibly fill the void around with the 4:1 perlite:furnace cement mix. The bottom would have a 1 inch of the mix and 1-1/4 bricks and the sides will be 6, 9x4.5x1.25" bricks standing high. The sides will have between 1/2" to 1/14" of the mix.
I'm looking to mainly melt aluminum and I have a waste oil burner that I used previous. So I'm wondering if this would be sufficient to my uses or a waste of my time? Any help would be appreciated.
