DEFINITION

Classification: 75/525

Impinging free falling molten metal stream or spray with a gas or solid agent or spraying (e.g., atomizing, etc.) of molten metal:

(under subclass 507) Process wherein a free falling molten metal stream or spray is impinged during free fall with a gas or solid agent or wherein a molten metal is sprayed (e.g., atomized, etc.) to treat the molten metal.

(1) Note. If a molten metal stream or spray is directed onto solid treating agent in a container or through a slag layer or used to mix separately added solid treating agent into molten metal, placement goes elsewhere under subclass 507.

SEE OR SEARCH THIS CLASS, SUBCLASS:

509, for treating a free falling stream of molten metal that contains over 50 percent by weight Iron (Fe) in a vacuum.
