Abstract
The Hatch Continuous Reduced Iron Steelmaking Plant (CRISP) close couples conventional,
established technologies: a direct reduction shaft furnace and a stationary arc furnace 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 furnace as a continuous melter of direct reduced iron (DRI) and scrap. The Hatch CRISP concept provides meaningful capital and operating cost savings stemming from the beneficial features of this facility. Although greenfield installations would advantageously incorporate hot charging of DRI, the concept of Hatch CRISP also allows the use of cold charge.
