The Non-Crucible Furnace was designed for continuous aluminum melting operations as a durable refractory lined furnace that does not use crucibles. Metal is charged into a dry hearth charging chamber. This unique feature on a small to medium size melting furnace eliminates the safety issue of operators placing cold, wet or moisture bearing charge materials into a molten bath of aluminum. It substantially improves the operating efficiency by capturing exhaust energy to preheat and melt the new charge. It improves metal quality by leaving the slag, dross and residuals from the melt on the dry hearth where they can be easily removed. The result is less post melt processing because contaminants never enter the molten aluminum. Full access for cleaning is provided through a manually operated top access cover. 
 
The Non-Crucible Furnace uses a bonded particle vertical gate filter located between the melt chamber and dip-well that assures only clean, filtered aluminum enters the dip-well area.  A factory installed inert gas pressure regulator with flow control supplies inert gas to a ceramic degassing device.  This continuous, controlled degassing system operates at the metal entrance of the dip-well and assures superior quality aluminum is available when required.  
 
The new Non-Crucible Furnace is also available with an optional factory installed Safety-Tap™. This mechanical metal transfer assembly is the same device used worldwide with the larger Thermtronix® High-Bay™ furnaces. It allows the operator to stand safely behind the flow of molten metal while transferring large quantities of aluminum from the dip-well directly to a pouring ladle. The Safety-Tap™ eliminates the need for a tilting style furnace and assures clean molten aluminum is withdrawn below the surface of the molten bath.
