摘要

本钢采用铁水预处理-150t复吹转炉-LF-RH-350 mm × 470 mm连铸、M-EMS-连轧工艺生产φ130～170 mm石油钻杆连接套用钢SAE4137M(/%:0.35～0.38C、0.15～0.35Si、0.85～1.00Mn、≤0.015P、≤0.008S、0.90～1.20Cr、0.28～0.33Mo、≤0.005Ca、≤0.0090N)。通过转炉出钢过程加复合脱氧剂

LF扩散脱氧全程吹氩搅拌

RH"软吹氩"

严格控制喂钙线量

控制连铸钢水过热度20～30℃

使钢材中氧含量为(13～15)×10

-6

氢含量(0.4～0.5)×10

-6

氮含量为(35～44)×10

-6

残余钙含量(12～18)×10

-6

并保证钢中Al/N≥2

满足石油用钢的要求。

Abstract

The Φ130-170 mm bar of steel SAE4137M for petroleum drill pipe connecting sleeve (/% : 0.35-0.38C

0.15-0.35Si

0.85-l.00Mn

≤ 0.015P

≤ 0.008S

0.90-1.20Cr

0.28-0.33Mo，≤ 0.005Ca

≤ 0.0090N) has been pilot-produced by hot metal pretreatment-150 t top and bottom combined blown converter-LF-RH-350 mm x 470 mm casting with M-EMS-continuous rolling process at Bengang. With adding compound deoxidizer during converter tapping

diffusion deoxidizing with argon stirring in LF refining

soft argon blowing and strict-controlling feeding calcium wire amount in RH refining

and controlling liquid overheating extent within 20-30 ℃

in steel products the oxygen content is (13-15 ) x 10

-6

hydrogen content (0.4~0.5) x 10

-6

nitrogen content (35-44)

x 10

-6

residual calcium content ( 12-18) x 10

-6

and Al/N is ensured ≥ 2

that all meet the requirement for petroleum steels
