Grants Contract for "SuperMelt"
Ed Mansell of Molten Metal Systems, LLC. has received an order from
Alcoa for his patented "SuperMelt"
Rotary Furnace. The furnace has a 60,000 lb. capacity and will be used
at Alcoa's Warrick Operations in
IN. Alcoa searched worldwide for a rotary furnace to meet their
They chose the
"SuperMelt" because of its versatility. In addition to the furnace
being mounted on a tilting frame, it has a
360 degree swivel base that allows charging and pouring from around the
entire perimeter of the furnace to
accelerate the ability to pour to various stations without the need to
reload and move equipment to the door.
This ability greatly reduces cycle time.
Alcoa will use the furnace to process coated scrap and recover aluminum
from dross in addition to melting
other types of scrap aluminum. The new furnace will allow processing of
dross and coated scrap on site
where currently it is shipped to a secondary processor for the metal to
be extracted and shipped back for
use in Alcoa's ingot plant. This process creates waste through lost
energy during the cooling, and excess
energy during reheating and transportation.
This will be the fourth "SuperMelter" and will have additional upgrades
to make it even more efficient than
the typical fixed type rotary furnaces. MMS currently has several
quotes out worldwide for this type of

Warrick's New Rotary Furnace Taking Shape
Department's new $7 Million furnace will begin operating in April
scrap, both of which are currently sent to outside processors to
Describing the furnace in terms that any of us
can understand, Chuck
Bargeloh, Warrick engineer
in charge of the installation, said "Some of us
describe it as a massive cement mixer on steroids.
Certainly, however, this is
different. And it's unique to the Ingot Department - unlike any
furnace we have."
The furnace's ability to rotate about a horizontal axis in
swiveling on a vertical axis gives
great flexibility and allows molten metal to
be poured from various stations along its perimeter. It is
designed to process
coated scrap created during our production process and dross, the
off the surface of molten metal before it can be cast into ingots.
Composed of inpurities
and oxides, dross is currently sent to outside processors to recover
aluminum. With the new
however, Warrick will be able to save money,
conserve significant energy and reduce environmental
effects by handling that
material internally. When dross is sent to outside processors, it must first cool.
cooled, the secondary processor must remelt it to extract the aluminum. They
also have to heat it higher than necessary so
the metal will remain molten for
its drive back to Warrick - this overheating causes additional melt
uses energy. With this furnace, we'll be able to process dross while it
still hot, rather
than letting that energy be wasted.
In addition to the furnace, the project also includes a
house, a salt silo, a liquid oxygen tank, and a weighing system. The Warrick County Council gave
project in August 2006 when they approved a tax phase-in of the assets over the
coming years. As part of the project, Bargeloh consulted with engineers at
Operations, which has its own rotary furnace in operation. By that knowledge
sharing process, Warrick will be able to have a shorter learning curve with the
new asset. Bargeloh is also working to make sure we get the new equipment
and in a quality manner.
"We're spending the time to make sure it's done
right," he said, "because this is certainly much more important than
just any old cement mixer, no
matter how beefed-up it looks."

Warrick's new Rotary Furnace into the
