摘要: 开发了唐钢160 t LD- 160 t LF-FTSR(Flexible Thin Slab Rolling) 流程生产冷轧用SPHC 钢(≤ 0.07%C,≤0.05%Si) 硼微合金化工艺,通过在精炼过程控制钢中Al含量(平均0.038%)和 Si含量(平均 0.038%),使LF 精炼后钢中的硼含量为0.0030%~0.0040%(平均含量0.0035%),硼的收得率达64%。

Abstract: The boron microalloying process of SPHC steel(≤0.07%C,≤0.05%Si)for cold rolling pro- duced by 160 LD- 160 t LF-FTSR(Flexible Thin Slab Rolling)flow sheet has been developed at Tangshan Steel, and with controlling Al content in steel(average 0.038%)and Si content(average 0.038%)during LF refining, the boron content in steel after LF refining was 0.0030%~0.0040%(average content 0.0035%),and the boron yield was up to 64%.
