Abstract
As a step towards continuous steelmaking, Hatch developed the Compact Reduced Iron Steelmaking Process (CRISP). Conventional established technologies are close-coupled into a unique plant configuration to provide significantly improved plant availability and energy efficiency at a lower capital cost. The key to the proposed concept is the innovative use of a stationary six-electrode arc furnace as a continuous melter of direct reduced
iron (DRI) and scrap. Although greenfield installations would advantageously incorporate hot charging of DRI, the concept of Hatch CRISP also allows the use of cold charge.
