Abstract
This invention is an electric arc furnace that can be continuously charged with ferrous materials, that can continuously melt the incoming charged materials, and that can semicontinuously tap molten steel by tilting to tap one side of the furnace or another. Continuous melting and refining can occur in lateral shafts adjacent to the central melting zone, and molten steel can be tapped from either of these shafts or directly from the central melting zone if desired. The furnace can be operated and tapped continuously, which provides many distinct advantages over what is currently available in the art.
