ABSTRACT:
An improved electric arc furnace provides increased capacity and reduced operating costs. The furnace has an ob-round shape which locates sidewalls further from the source of heat. The improved furnace can accept a larger scrap charge and provides a larger surface area for slag reactions to take place. All of these advantages are obtained without the need for building new foundations or ancillary equipment.
