摘要

采用50 t EAF-AOD-LF-VD-150 mm×150 mm坯连铸-高速线材连轧工艺生产9Cr18钢(/%:0.95C，0.35Si，0.37Mn，0.032P，0.002S，17.42Cr，0.01Mo)Φ5.5 mm盘条。通过控制[S]≤0.008%

添加0.05%稀土元素

连铸坯经1160℃高温扩散处理

Φ5.5 mm成品盘条采用860℃球化退火等工艺措施

检验结果表明

盘条中心和一般疏松

以及偏析均≤1.0级

共晶碳化物不均匀度1.0~2.0级

球化退火组织为球状珠光体+块状碳化物

抗拉强度750~780 MPa

伸长率20%~26%

具有良好的冷拔性能。

Abstract

The Φ5.5 mm rod coil of steel 9Crl8 (/% ： 0.95C

0.35Si

0.37Mn

0.032P

0.002S

17.42Cr

0.01Mo) is produced by 50t EAF-AOD- LF- VD- 150 mm x 150 mm billet concasting- high speed rod rolling process. With using the process measures including controlling [S] ≤ 0.008%

adding 0.05% RE elements

concasting billet high-temperature diffusion treating at 1160 ℃ and Φ5.5 mm rod coil products spheroidizing annealing at 860 ℃

the examination results show that of rod coil the rating o£ center and general porosity

and segregation are all ≤ 1.0

the rating of non-uniformity of eutectic carbide is 1.0-2.0

the spheroidizing annealing structure of rod is spheroidal pearlite + massive carbide

the rod has nice cold-drawing performance with tensile strength 750-780 MPa and elongation 20%-26%.
