The metallurgical aspects typical of this process, the high freezing rate provides an extremely refined solidification microstructure characterized by dendritic ramifications, improves segregation and increases the mechanical properties of metal. The aim of this work is develops the, CastMag Oscillation (CMO) technology.By multiphysics approach which combined fluid dynamics, heat transfer, process metallurgy, solidification, it is possible now to define new innovative processes with the integration of new design of Double-Helix CMO system. Future development of DH-CMO applicability is in agreement with energy savings and CO2 reduction demand. DRI produced at high temp. (> 777°C) with metallization up to 90-95% and controlled carbon ≤ 5%, and which is pneumatically transported from the reactor discharge to the meltshop for direct feeding to the EAF shop. The DRI is capitalized in the EAF. The typical configuration of DR-based EAF steel-shop involves moving bed reduction reactor producing cold discharged direct reduced iron, which could be either stored / sent directly to the electric furnace shop by means of conveyors. The DRI typically has a metallization level of up to 95% and carbon levels in the range of 1.75%-2.3%. The DH-CMO is anti-bulging technology is an innovative solution transforming continuous casting to make it safer, faster, and more reliable. EM processing can be classified by type of magnetic field involved: from AC to DC field. These processes are suitable for heating, melting, flow, shape control, solidification control (stirring, pumping), for each application a specific configuration needs to be defined, selected and optimized continuous-casting.
