摘要

研究了900℃均热+500℃铅浴54 s空冷处理对70钢(0.67%～0.75%C)Φ5.5 mm热轧钢丝经38.9%压缩率拉拔的冷拔钢丝组织和性能的影响。结果表明

500℃铅浴等温处理

该钢过冷奥氏体转变的孕育和转变时间最短

该钢丝抗拉强度提高了21.4%

伸长率提高9.5%

为随后通过细拉工艺进一步提高钢丝的综合力学性能建立了基础。

Abstract

Effect of 900 Y soaking + 500 °C patenting for 54 s

air cooling treatment on structure and properties of cold drawn wire of 70 steel (0. 67% ~0. 75% C) with 38. 9% reduction from Φ5. 5 mm hot rolled wire has been studied. Results show that with 500℃ patenting treatment the inoculation and transformation time of under-cooling austenite of the steel is shortest

the tensile strength and elongation of steel wire increase respectively by 21. 4% and by 9. 5% to establish the foundation for further increasing the comprehensive mechanical properties of steel wire by finishing fine drawing process.
