Abrégé

An exemplary furnace system for melting stock metal includes a main hearth and a side well subsystem, which includes a melting well disposed downstream of the main hearth for receiving flow from the main hearth, an input flow inducer disposed upstream of the melting well and downstream of the main hearth, and an output flow inducer disposed downstream of the melting well and upstream of the main hearth. The input flow inducer drives molten metal into the melting well, thereby forming a differential metal head in the melting well. The output flow inducer evacuates molten metal from an output conduit, thereby reducing counter-pressure at an output port of the melting well communicating with the output conduit. This allows atmospheric pressure to add to the differential metal head in the melting well, resulting in an increase in productivity of the side well subsystem and of the furnace system as a whole.

Embodiments of an aluminum dross cooling head are disclosed. The cooling cooperates with a material container encapsulate dross and reduce thermiting of the dross. In one embodiment, the cooling head also serves as a compression head when forced into the dross by a cooperating dross press assembly.

Abrégé

A tilting rotary furnace with a door assembly that seals against a furnace vessel. The seal between the door and the furnace vessel allows for regulation of the internal environment of the furnace and control over thermitting of the aluminum. As a result, aluminum recovery may be carried out without the use of salt. A portion of the door may rotate with the furnace vessel and a portion of the door may remain rotationally stationary with respect to the furnace vessel and the rotating portion of the door.

Abrégé

A method of cooling aluminum dross, comprising: placing the dross into a
receptacle of a
material container; and placing a cooling head on top of the dross so that a
downwardly
projecting portion of the cooling head engages the dross and locally deforms
the dross under the
weight of the cooling head; wherein: the cooling does not include the use of a
dross press
assembly to exert mechanical force to the dross prior to placing the cooling
head on the dross;
and the cooling head seals against the material container to at least
partially encapsulate the dross
and extinguish oxidation of the dross, and the seal is formed by engagement of
an upper rim of
the material container into a channel of the cooling head, wherein the channel
is formed inside
the upper rim of the material container by a portion of the cooling head that
is thicker than a
portion of the cooling head located above the upper rim.

Abrégé

A process for increasing the percentage of metal recovery from dross containing metal particles of different sizes having oxide and salt components adhered thereto. The process includes crushing and tumbling the dross to mechanically remove all of the oxide and salt components from the larger of the metal particles, separating the larger metal particles from the removed oxide and salt components and the smaller metal particles to provide a supply of larger metal particle concentrate, separating the removed oxide and salt components from the smaller metal particles, mechanically impacting the smaller metal particles to remove any additional oxide and salt components from the smaller metal particles, and separating the smaller metal particles from the additional oxide and salt components to provide a supply of smaller metal particle concentrate.
