20080213717 | METHOD OF INCREASING THE EFFICIENCY OF MELTING METAL - A process for increasing the thermal radiation absorbance of objects that are to be melted or softened. An agent is applied to the object, such as an aluminum sow, and the object is placed in a furnace. The furnace exposes the object to thermal radiation, such as by blasting the sow with jets of burning gas, and the material melts. The increase in absorbance on the outer surface of the object reduces the amount of energy needed to melt or soften the material, as thermal energy is absorbed by the object more rapidly than uncoated materials. | 09-04-2008 |
