Zusammenfassung: | The invention relates to the technical field of low-carbon steel production, in particular to a method for producing anti-aging low-carbon steel by adopting a ferrite rolling process. Specifically, the low-carbon steel comprises the following chemical components in percentage by mass: larger than 0.003% and smaller than or equal to 0.060% of C, smaller than or equal to 0.10% of Si, smaller than orequal to 0.25% of Mn, smaller than or equal to 0.020% of P, smaller than or equal to 0.03% of S, smaller than or equal to 0.05% of Alt, larger than or equal to 0.0015% and smaller than or equal to 0.0050% of B, smaller than or equal to 0.008% of N and the balance of Fe and inevitable impurities, and strip steel with different thicknesses is prepared after smelting, casting, rolling and coiling. The low-carbon steel produced by the process has good aging resistance and more excellent mechanical properties, the production cost is greatly reduced, and a win-win effect of reducing the cost and improving the quality is ac |
