摘要

分析和研究了用 30 t EBT电弧炉 40 t LFV精炼工艺冶炼Mn Cr、Cr Mo、Cr Ni Mo系等汽车用新型齿轮钢时

真空度、精炼渣、吹Ar工艺和 [Al

]

s对钢中氧含量的影响

得出真空度小于10 × 133Pa

吹Ar 100～150 L/min

精炼渣碱度25～30

控制 [Al

]

s为0.02%～0.04%时可以获得低氧含量。生产结果表明

Mn-Cr系、Cr-Mo系和Cr-Ni-Mo系齿轮钢氧含量为(12～20 )× 10

-6

达到汽车用新型齿轮钢氧含量的标准要求

Abstract

The effect of vacuum

refining slag

argon stirring process and [Al

]

s on oxygen content in steel has been analyzed and studied in production of Mn-Cr

Cr-Mo and Cr-Ni-Mo series new type gear steels for car by 30 t EBT are furnace-40 t LFV refining process to get that it is available to obtain lower oxygen content in steel by the operation with vacuum less than 1.33 kPa

100~150L/min Ar stirring

refining slag basicity 2.5～3.0 and controlling [Al

]

s between 0.02% and 0.04%.The production results showed that the oxygen content in Mn-Cr

Cr-Mo and Cr-Ni-Mo series gear steels was between 12×10

-6

and 20×10

-6

up to standard requirement for oxygen content in new type gear steels for car.
