                                                                                   ALCOA Grants Contract for "SuperMelt" Rotary Furnace

                                          Ed Mansell 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 Newburgh, IN.
                                          Alcoa searched worldwide for a rotary furnace to meet their requirements. 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. Mansell currently has several quotes out worldwide for this type of
                                          Alcoa Warrick Operations is one of the largest aluminum smelting and fabricating facilities in the world
                                          housing a 309,000 metric ton per year primary aluminum smelter and rigid packaging operation employing
                                          more than 2,100 people, with more than 120 acres under roof and 14,000 total acres.

                                                Warrick's New Rotary Furnace Taking Shape

                                         The Ingot Department's new $7 Million furnace will begin operating in April processing dross
coated scrap, both of which are currently sent to outside processors to recover aluminum.
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 much different. And it's unique to the Ingot Department - unlike any
                                         other furnace we have."

                                                       The furnace's ability to rotate about a horizontal axis in addition to 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 material that
                                         is skimmed 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 furnace,                                        

                                         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. Then, after it's 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
                                         loss and uses energy. With this furnace, we'll be able to process dross while it is still hot,  rather
                                         than letting that energy be wasted.

                                         In addition to the furnace, the project also includes a lime-injected bag house, a salt silo, a liquid oxygen 
tank, and a weighing system. The Warrick County Council gave support to the 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 Tennessee 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 installed safely 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."

                                               Ingot Department for final assembly.
