Mass flow gravity feed furnace charger apparatus includes (1) a charge-well cover having an aperture and (2) an essentially vertical conduit for forming a substantially vertically-oriented column of metal chips or scrap within and above the aperture, and (3) structure for bringing both (
5407462 Mass flow gravity feed method for charging metal-melting furnaces and apparatus therefor April 18, 1995
A mass flow gravity feed furnace charger comprises a vertically-oriented elongated hollow conduit which is associated with an apertured heat-resistant charge-well cover adapted to lie essentially in contact with the upper surface of a molten metal pool in the charge well of a metal-m
5211744 Method and means for improving molten metal furnace charging efficiency May 18, 1993
Utilization of metal chips, especially scrap metal chips, particularly brass and aluminum, by introduction of the metal chips into a pool of molten metal of which they are formed or an alloy thereof, with minimization of fuel cost, heat loss, and minimal conversion of the metal at th
4872907 Metal chip furnace charge apparatus and method October 10, 1989
Apparatus and method for charging metal chips into a molten bath of the metal from which the chips are formed, comprising a compacting extruder and a delivery conduit which is resistant to the mass of molten metal and which is pivotable to dip into the molten metal bath when chips are be
4721457 Method and apparatus for cleaning and drying metal chips January 26, 1988
There is disclosed a process for producing dried and cleaned metal chips by entraining metal chips in a gas, introducing the gas into a cyclone separator having a wall heated to fluid-vaporizing temperature by combustion effected in a surrounding chamber, purging fluid from said chip
4710126 Method and apparatus for drying metal chips December 1, 1987
There is disclosed a process for producing dry metal chips by entraining fluid-containing metal chips in a gas, introducing the gas into a cyclone separator having an internal wall heated to fluid-vaporizing temperature by combustion in a surrounding chamber, purging and vaporizing fluid
4702768 Process and apparatus for introducing metal chips into a molten metal bath thereof October 27, 1987
A process for the introduction of metal chips, especially scrap metal chips, into a molten mass of the metal of which said chips are formed, wherein the essentially dry chips are first compacted and placed into strip form, and then introduced into the molten metal bath in such strip
