Abstract:
An apparatus for conducting the process of continuous melting of solid charge materials comprising an elongate rotary fu ace having horizontal longitudinal disposition and annular end openings adapted for containing a partially melted bath of charge materials in a gas-solid-liquid reaction zone heated by a hot gas stream passing over said bath, characterized by the combination of:means for maintaining a gas-solid liquid reaction zone within said furnace adapted for containing a partially melted bath heated by a hot gas stream passing over said bath; means for conveying solid charge materials through at least one of said end openings into said hot gas stream and along said gas solid-liquid reaction zone and downwardly projecting said charge materials directly into said bath; means for continually traversing aid means for said conveying and downwardly projecting said charge materials successively backwards and forwards adapted for longitudinally distributing the entry location of aid charge materials directly into said bath along a longitudinal traverse span of said gas-solid-liquid reaction zone; and means for liquid metal exit allowing liquid metal to flow out of said gas-solid-liquid reaction zone adapted to provide for replenishing said bath by said solid charge materials.
