Abstract Scope |
This contribution outlines the low emission production process and metallurgical design of ultra-high strength steel produced by the latest iteration of thin slab direct rolling. To maintain energy- and emission-efficient production, the metallurgical design of ultra-high strength steels manufactured by thin slab direct rolling must account for numerous physical constraints. These constraints for microalloyed thermo-mechanically processed steels include restricted maximum carbon, low equalizing furnace temperature relative to traditional integrated mill methodologies, and generally high baseline nitrogen. Production of a minimum 700 MPa (100 ksi) yield strength hot-rolled steel is demonstrated with combined Scope 1 & 2 emissions less than 0.40 ton CO2 equivalent per ton steel. |
