    摘要： 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.

    摘要： A method of atomization of refined metal is taught. The method starts with the introduction of unrefined metal into an electroslag refining process in which the unrefined metal is first melted at the upper surface of the refining slag. The molten metal in the form of droplets is refined as it passes through the molten slag. The refined metal droplets are collected in a cold hearth apparatus having a skull of refined metal formed on the surface of the cold hearth and protecting the cold hearth from the leaching action of the refined molten metal. A cold finger bottom pour spout is formed at the bottom of the cold hearth to permit dispensing of molten refined metal from the cold hearth. The rate of flow of molten metal through the cold finger apparatus is controlled principally by controlling the rate of melting of the unrefined metal. The metal flowing from the cold finger apparatus is introduced to the upper end of a ceramic melt guide tube. Liquid metal emerging from the lower end of the melt guide tube is atomized by a gas orifice closely coupled to the lower end of the melt guide tube.

    摘要： A teeming spout has on its inside a plurality of picket-like metal segments (1) separated from one another by slots (2) and is externally surrounded by an induction coil (3). The bottom turn (7) of this induction coil (3) has a downwardly directed pitch equalization piece (8) which provides such that the field acts uniformly on the teeming stream from all sides and therefore it is not deflected.
