An apparatus and method relate to tapping a molten metal bath from a reactor. The apparatus includes a tapping pipe having a tapping pipe inlet and tapping pipe outlet for withdrawing a portion of the molten bath from the reactor. The molten bath can flow from the reactor through the tapping pipe inlet through tapping pipe to a tapping pipe exit. The tapping pipe is attached to the reactor at the tapping pipe inlet and the tapping pipe includes a susceptor, formed of a suitable material, such as graphite, which heats upon application of induction current. An induction coil assembly is annularly disposed about the tapping pipe, wherein the induction coil assembly can apply an induction current to heat the tapping pipe to a temperature that is higher than that of a solidified bath metal component within the tapping pipe. The induction current melts the solidified bath metal, whereby the molten metal bath can be tapped from the reactor. A slidable gate valve assembly can be attached at the tapping pipe outlet for further control of tapping.

[ We claim:] [1.] An apparatus for tapping a molten metal bath from a reactor, comprising:a) a tapping pipe, having a tapping pipe inlet and a tapping pipe outlet, said tapping pipe being attachable at said tapping pipe inlet to the reactor and said tapping pipe including a susceptor, whereby said tapping pipe can be heated by an induction current to a higher temperature than that of a solidified bath metal component within said tapping pipe;b) an induction means at the tapping pipe, wherein said induction means can apply an induction current to the susceptor to heat the tapping pipe to a temperature that is higher than that of said bath metal within said tapping pipe and thereby melt said solidified bath metal to tap the molten metal bath from the reactor; andc) a ceramic insert that lines the tapping pipe to substantially prevent contact of the tapping pipe by the metal melt being tapped through said tapping pipe.
