DEFINITION

Classification: 75/509

Free falling stream or spray of molten Iron (Fe):

(under subclass 508) Process wherein an unconfined stream or spray of a molten metal that contains over 50 percent by weight Iron (Fe) is treated in a vacuum.

(1) Note. In a process for this subclass the stream or spray remains molten during treatment and then coalesces after treatment to form a pool of molten metal.
