Abstract
The economics of the Hatch Continuous Reduced Iron Steelmaking Process (CRISP) are compared with conventional
electric arc furnace technologies charging cold and hot direct reduced iron (DRI). CRISP project returns are estimated
at 17% as compared with only 13% for a hot DRI charged EAF and 10% for a cold DRI charged EAF. Project returns
for CRISP can be increased significantly by (i) utilizing the potential of the CRISP technology matching a CRISP
furnace to a high-production (>2.0 million plus tonnes/year) DRI production unit, or by (ii) operating in a DRI friendly
region where natural gas and iron ore are inexpensive. The CRISP capacity is scalable from <0.5 to 2.0 million
tonnes/year liquid steel and is more flexible than conventional EAF operations.
