EXPERIMENTS ON THE DEPHOSPHORIZATLON OF HIGHLY ALLIED MANGANESE STEEL WITH HIGH PHOSPHORUS

The practical application of dephosphorization is discussed in this paper, aiming to address the high phosphorus content in austenitic manganese steel waste re-melting, which can exceed admissible limits. Phosphorus notably affects the hardness, tensile strength, ductility, and resistance to shock or impact of steel. To investigate the effectiveness of dephosphorization, experiments were conducted in laboratory conditions, demonstrating a significant and rapid reduction in phosphorus content in highly allied manganese steel. The results were consistent with industrial applications, although the level of dephosphorization achieved in the laboratory was higher than that obtained on an industrial scale, despite both experiments being conducted under similar conditions. This study highlights the potential for effective dephosphorization in both laboratory and industrial settings, indicating that while practical applications can yield results, laboratory methods may offer improved outcomes.
