This abstract first appeared for US patent application 20250108451 titled 'HYDROGEN PLASMA ARC ADDITIVE MANUFACTURING OF SUSTAINABLE IRON AND STEEL
Original Abstract Submitted
a scalable method for the manufacture of iron and steel. the method includes hydrogen plasma arc additive manufacturing of near net shape steel and iron parts. more specifically, the method includes the hydrogen plasma reduction of iron ore concentrates using a plasma arc welding (paw) torch and hydrogen and argon shielding gases. the plasma arc generated by the paw torch and the hydrogen and argon shielding gases strip electrons from the feedstock, for example a ribbon comprising fine iron ore concentrates, as part of an additive build, thereby avoiding the need for post-processing operations such as casting, rolling, and forging operations.
