I Made a BIG Furnace to Melt Metals

Propane furnace made with scrap steel, glass and ceramic wool and refractory cement. I wanted to reline the coal furnace i made five years back to melt aluminum but the structure was in very bad shape as it has been outside to the elements since I made it. So instead I made a new one that runs on propane with two venturi burners I made recently: This has been very long project to make but definetly worth the time as now melting aluminum is much easier and also cheaper. The furnace holds a 230mm tall crucible of 180mm in diameter, it should hold 35kg of aluminum. Insulation from the inside out is composed of: refractory cement, ceramic wool, glass wool. On the bottom center I inserted a refractory brick to have someting very solid to place the crucible on. The lid is made just of recfractory cement, it s 58cm in diameter and 5cm thick, so it weights 20kg. 0:00 Frame 2:16 Insulation 6:02 Lid hinge 7:09 Lid 9:31 Assembly 10:55 Test T
