Gas / Oil Lift Out Crucible Furnace The steel furnace casing is lined with 60% alumina firebricks backed with high-grade insulation. All L.O furnaces are designed for operation with Morganite Excel or Clay-graphite crucibles and stands. The swingaside cover of the furnace has a central exhaust which deflects the exhaust flame over the top of the crucible to preheat the solid charge. Gas / Oil Central Axis Tilting Furnace The steel furnace casing is lined with high grade refractories, backed by insulation, to suit the application and is designed to accommodate MORGANITE Salamander crucibles and stands. Central Axis pouring is achieved by tilting the furnace body about a central point by means of a conveniently placed hand-wheel. Molten metal is poured over the top of the crucible into the transfer ladle. Alternatively, the furnace can be fitted with a spouted crucible and muffle ring. Exhaust gases pass through a number of parts in the refractory cover around the crucible. In addition, the furnace can be fitted with a back exhaust.
