摘要

Nb-RE微合金化TGM2高速钢(%:0.88～0.89C、4.14～4.16Cr、4.73～4.76Mo、6.09～6.12W、1.85～1.86V、0.05～0.10Nb、0.05～0.06RE)由25 t EAF-30 t LF(VD

加Nb-RE)-1 t ESR工艺冶炼。试验结果表明

经Nb-RE微合金化后

TGM2高速钢Φ96 mm材淬火晶粒尺寸明显细化

晶粒度由原来未微合金化钢的9.5级提高至10～10.5级;淬、回火后硬度HRC为65.2～65.8

600℃4 h红硬性HRC为62.1～62.3

Nb-RE TGM2钢制成刀具的切削寿命较原TGM2钢提高20%。

Abstract

Nb-RE microalloying high speed steel TGM2 (% : 0. 88 ~ 0. 89C

4. 14 ~ 4. 16Cr

4. 73 〜4. 76Mo

6. 09 〜6. 12W

1.85 ~ 1.86V

0. 05 〜0. 10Nb

0. 05 〜0.06RE) was melted by 25 t EAF- 30 t LF (VD

adding Nb- RE) - 1 t ESR process. Test results show that with Nb-RE microalloying

the grain size of quenched Φ96 mm bar of high speed steel TGM2 is obviously fine i. e. the grain rating increases to 10 ~ 10. 5 from 9. 5 of original steel without microalloying； the hardness HRC of quenched and tempered Nb-RE steel is 65. 2 ~65. 8 and its red hardness HRC at 600 °C for 4 h is 62. 1 〜62. 3 ； as compared with original TGM2 steel without added Nb-RE

the service life of tool manufactured by Nb- RE TGM2 steel increases by 20%.
