Methods and apparatus for removing condensed metal from the surfaces of metal processing chambers, such as, vacuum induction melting (VIM) furnaces having, for example, condensed Mg or Ti, are disclosed. The methods and apparatus provide a robotic arm end positioned in the furnace having a nozzle operatively connected to a source of dry ice. The robotic arm end directs a stream of dry ice particles against the surface of the furnace to displace condensed metal. The displaced metal is collected for reuse or disposal. Aspects of the invention provide a safe and automated process for cleaning process chambers and recovering metal that can typically be dangerous when performed by conventional methods. |
