| Abstract: | By analyzing the mechanical properties of 30MnSi prestressed concrete （PC） steel bar produced by the processes of smelting-rolling-drawing-heat treatment, the production process was optimized. The qualified products of 30MnSi PC steel bar was produced in batches after using the following measures to lower the inclusion content in the molten steel： improving the qualities of raw and auxiliary materials, operating with high catch carbon and post blowing practice, modifying the top slag in the ladle, adjusting the parameters of bottom argon blowing, sealed the long nozzle with argon gas, applying of turbulence inhibitor in tundish and mold electromagnetic stirring in the continuous caster. |
| Keywords: | prestressed concrete steel bar process optimization inclusion 30MnSi steel |
