Abstract
An apparatus and method for charging a melting furnace having a charging opening in its sidewall, in which a closed housing contains a vibrating pan having an intergal discharge chute adapted to extend into the charging opening in the furnace sidewall; and a truck-mounted carriage for moving the charging apparatus into the charging opening of the furnace and removing the apparatus to a position remote therefrom. A method for feeding the furnace over a predefined area, and continuously feeding the furnace during all phrases of operation, including slagging and tapping, is also disclosed.
Claims8
Apparatus for charging a tilting electric melting furnace, which is tiltable about a horizontal tilting axis, from a charging conveyor, the melting furnace having a charging opening in its sidewall, the horizontal tilting axis of the furnace passing through such charging opening, such charging apparatus comprising:
- a track mounted carriage;
- a support frame mounted on said carriage;
- vibrating means mounted on said support frame;
- an elongated vibrating pan mounted on said vibrating means;
- said vibrating pan having a discharge end adapted to extend into the charging opening in the furnace sidewall;
- means for effecting a gas-tight seal between said apparatus and said furnace;
- means for moving said discharging end of the vibrating pan into the charging opening of said furnace and to a position remote therefrom;
- an independently mounted cover above said vibrating pan, and means for effecting a gas-tight seal between said vibrating pan and said cover;
- whereby said furnace is capable of tilting about said horizontal tilting axis while said vibrating pan is situated within said charging opening.
Apparatus according to claim i including means for effecting a gas-tight seal between said apparatus and an adjacent charge preheater.
A method for continuously charging a melting furnace through its sidewall, comprising:
- receiving heated charge materials in an enclosed housing;
- continuously vibrating said charge materials within the housing;
- and
- discharging said materials from the housing into the furnace onto a chute which receives said materials and discharges them at an angle from the horizontal of from 20 to 40 degrees.
