With HI T.E.Q’s stack charge melter, aluminum ingots and scrap are loaded into the top stack of the melter. Fuel-fired burners, firing up through the charge, serve to both melt the material lower in the stack and heat the higher material. As the melted aluminum flows from the melt chamber to the hold chamber, the preheated metal drops lower and is itself melted. New material is added to the top of the stack..

Low flue temperatures result in reduced NOX emissions, reducing pollution control equipments requirements. With no wet bath charging, the stack charge furnace enhances operator safety. Optional pressure pump well available for ladle filling. Melting rates are available with production through-puts ranging from 500kg/h to 4550kg/h.

The Stack Charge Melter’s energy savings, greater production and reduced emissions control costs offer aluminum casters a quick payback on their investment.
