In the paper, the effects of composition adjustment on mechanical properties and production costs of steel are systematically studied through optimizing the composition control range of such strengthening elements as Mn, Ti and N as well as adopting staged industrial tests and regulating methods of closed-loop characteristics aiming at such problems as higher strength of raw materials in hot rolling, more roll consumption of pickling line tandem cold mill, easy slipping of rolling mill, large fluctuation of yield strength and higher costs in the production of S350GD+ZAM and S450GD+ZAM Zn-Al-Mg structural steels. The results showed that the mechanical properties of both products could meet standard requirements after optimization, rate of reaching the standard for properties of S350GD+ZAM was increased from 96.4% to 98.7%, allowance of yield strength for S450GD+ZAM was sufficient and its rate of reaching the standard was 98.2%; accumulated cost reduction of them in 2024 was RMB 749,320 Yuan so that production bottleneck was effectively broken as well as cost decreasing and benefit increasing were realized, which could provide reproducible industrial technical path for low-cost and stable productions of structural steel with Zn-Al-Mg coating.

文章针对S350GD+ZAM、S450GD+ZAM锌铝镁结构钢,在生产中存在热轧原料强度偏高、酸轧辊耗大、轧机易打滑、屈服强度波动大、成本偏高等问题,通过优化Mn、Ti、N强化元素成分控制范围,采用分阶段工业试验与性能闭环调控方法,系统地研究了成分调整对钢材力学性能及生产成本的影响。结果表明:优化后两类产品力学性能均满足标准要求,S350GD+ZAM性能达标率由96.4%提升至98.7%,S450GD+ZAM屈服强度余量充足、达标率为98.2%;2024年两类产品累计降本74.932万元,有效解决生产瓶颈,实现降本增效,为锌铝镁镀层结构钢低成本稳定生产提供可复制的工业化技术路径。

文章针对S350GD+ZAM、S450GD+ZAM锌铝镁结构钢,在生产中存在热轧原料强度偏高、酸轧辊耗大、轧机易打滑、屈服强度波动大、成本偏高等问题,通过优化Mn、Ti、N强化元素成分控制范围,采用分阶段工业试验与性能闭环调控方法,系统地研究了成分调整对钢材力学性能及生产成本的影响。结果表明:优化后两类产品力学性能均满足标准要求,S350GD+ZAM性能达标率由96.4%提升至98.7%,S450GD+ZAM屈服强度余量充足、达标率为98.2%;2024年两类产品累计降本74.932万元,有效解决生产瓶颈,实现降本增效,为锌铝镁镀层结构钢低成本稳定生产提供可复制的工业化技术路径。

In the paper, the effects of composition adjustment on mechanical properties and production costs of steel are systematically studied through optimizing the composition control range of such strengthening elements as Mn, Ti and N as well as adopting staged industrial tests and regulating methods of closed-loop characteristics aiming at such problems as higher strength of raw materials in hot rolling, more roll consumption of pickling line tandem cold mill, easy slipping of rolling mill, large fluctuation of yield strength and higher costs in the production of S350GD+ZAM and S450GD+ZAM Zn-Al-Mg structural steels. The results showed that the mechanical properties of both products could meet standard requirements after optimization, rate of reaching the standard for properties of S350GD+ZAM was increased from 96.4% to 98.7%, allowance of yield strength for S450GD+ZAM was sufficient and its rate of reaching the standard was 98.2%; accumulated cost reduction of them in 2024 was RMB 749,320 Yuan so that production bottleneck was effectively broken as well as cost decreasing and benefit increasing were realized, which could provide reproducible industrial technical path for low-cost and stable productions of structural steel with Zn-Al-Mg coating.
