摘要

首钢三炼钢厂采用铁水脱硫-80tLD冶炼-LF(喂丝)精炼-4流方坯连铸工艺生产制动梁用微合金化钢15Mn2CrVNbE(%:0.13～0.17C、1.44～1.59Mn、0.30～0.60Cr、0.02～0.10V、0.02～0.05Nb、0.02～0.05Al)。通过控制钢中Al含量、吹氩、喂硅钙线和全程保护浇铸等工艺措施

149炉生产结果表明

铸坯中氧含量为(7～26)×10

-6

氮含量为(29～79)×10

-6

。制动梁成品的力学性能为σ

465～575MPa

630～720MPa

25%～34%

-40℃纵向冲击功36～183J

满足使用要求。

Abstract

The microalloying steel 15Mn2CrVNbE(0. 13~0. 17C

1.44～1.59Mn

0.30～0.60Cr

0.02～0. 10V

0.02~0.05Nb

0.02~0.05Al)for trigging girder has been produced by hot metal desulphurizing -80 t LD melting-LF (feeding wire)refining - 4 strand billet concasting process at No3 steelmaking plant

Shougang. The production results (149 heats)showed that with control of Al content in steel

argon stirring

feeding silicon-caleium wire

whole course shielding casting technology

the oxygen content in billet was(7～26)×10

-6

nitrogen content was(29～79)×10

-6

and the mechanical properties of trigging girder products were σ

465～575 MPa

630～720 MPa

δ₅25%~34% and -40 ℃ longitudinal impact energy 36~183 J

which met the requirement of service.
