Gingery-Style Crucible Furnace
by roughtyper, published
This is a half scale model of my version of the furnace part of a gas fired Gingery-style crucible furnace for melting metals. I was trying to wrap my head around the assembly / proportions / through-holes, so I put together an exploded model.
This thing was made with Tinkercad. Edit it online https://tinkercad.com/things/k2j0fnVuxWs
In real life, once cast in refractory cement, these parts just stack on top of each other and gravity does the rest. A crucible is set on top of the plinth (in yellow). Gas flame enters through the hole in the side, forming a vortex around the crucible which melts the metal.
Later, I may put together the supporting and lifting framework just to have an idea of how the complete furnace is assembled.
If you decide to use this as a scale model to construct your own crucible furnace, it would be polite to purchase a copy of Mr. Gingery's book.
