Manufacturing and Properties of Spherical Iron Particles from a By-Product of the Steel Industry

In modern cold rolling mills in the steel industry, iron oxide powder is produced as a by-product when used pickling agents are recycled. Further processing of these powders could enable production for various applications metallurgy. For this purpose, new process route with an eco-friendly hydrogen reduction treatment was developed. The able to manufacture variety particles through minor adaptations. It possible spherical high flowability. flowability measured by Revolution Powder Analyzer, and avalanche angle 47.7° determined. addition, bulk density measurements processed collective achieved values 3.58 g/cm3, morphology be observed SEM analysis. properties show potential where required, e.g additive manufacturing, thermal spray hot isostatic pressing. By adjusting conditions developed process, irregular also manufactured from same very specific surface 1640 cm2/g low 1.23 g/cm3. Therefore, property profile suitable friction metallurgy material. summary, combination offers cost-efficient sustainable alternative conventional manufacturing applications.
