Abstract

A metal fume reduction apparatus for a snout disposed between an outlet of a heat treatment furnace and a molten metal plating tank, includes: a main pipe part; an introduction pipe part and a return pipe part each of which is configured to couple the snout to the main pipe part so that an interior space of the snout communicates with the main pipe part; and a cooling part configured to cool a cooling target site, of the main pipe part, located between a first connection portion with the introduction pipe part and a second connection portion with the return pipe part in a longitudinal direction of the main pipe part. The cooling target site is located below the first connection portion of the main pipe part in a state where the main pipe part is coupled to the snout via the introduction pipe part and the return pipe part.
