60Si2MnA弹簧钢脱氧工艺的优化

Optimization of Deoxidization Technology for Spring Steel 60Si2MnA

在现场调研的基础上 ,对用 30 t L F生产 6 0 Si2 Mn A弹簧钢的脱氧工艺进行优化控制。结果表明 :在不进行夹杂物变性处理的条件下 ,可生产出平均氧含量为 2 3× 10 - 4 %、最低氧含量为 16× 10 - 4 %的 6 0 Si2 Mn

By study on 30 t LF deoxidization technology in practice, the parameters of deoxidization technology have been optimized and controlled. The result shows that the spring steel 60Si2MnA which average oxygen content is 23×10 -4 %, lowest oxygen content is 16×10 -4 % can be obtained without modifying inclusions.
