摘要

通过50 kg真空感应炉研究了09CuPTiRE钢Al脱氧后加0.042%RE处理和Al脱氧后喂CaSi线-加 0.042% RE处理后14 mm钢板中的夹杂物和横向冲击韧性。结果表明，加RE处理，稀土回收率12%

钢中RE 0.005%

RE/S为1.0

钢中夹杂物为链状稀土氧硫化物和稀土氧化物，20℃钢板平均横向冲击功112 J;喂CaSi线- 加RE处理，稀土回收率31%

RE/S为2.2

钢中RE 0.013%

钢中夹杂物为球状钙硅酸盐和稀土氧硫化物复合夹杂，20 ℃钢板平均横向冲击功提高至130 J。喂CaSi线-加RE工艺优于加RE工艺。

Abstract

Inclusion and transversal impact toughness of 14 mm plate of steel 09CuPTiRE with adding 0.042% RE or feeding CaSi wire-adding 0.042%RE after Al deoxidation have been studied by a 50 kg vacuum induction furnace. Re- sults showed that ysth adding RE treatment

the RE yield was 12% with0.005% RE in steel and RE/S =1.0

the inclu- sions in steel were RE oxysulphide and RE oxide and the average transversal impact energy at 20 ℃ of plate was 112 J; with feeding CaSi wire -adding RE treatment

the RE yield was 31% with 0.013%RE in steel and RE/S = 2.2

the in- clusions in steel were compound of spherical calcium silicate and RE oxysulphide and the average transversal impact energy at 20 ℃ increased to 130 J. The feeding CaSi wire -adding RE process was better than only adding RE process.
