摘　　要：文章研究了不同调质热处理工艺对30CrMoA抽油杆用圆钢显微组织和力学性能的影响。针对30CrMoA钢的实际应用要求,通过调节淬火温度和回火温度,优化热处理工艺,以提高材料的强度和韧性。试验结果表明,适当的调质处理能显著提高材料的屈服强度、抗拉强度、屈强比和冲击功,尤其在850℃淬火(水冷)+540℃回火(水冷)条件下,30CrMoA抽油杆用圆钢表现出最佳的综合机械性能,具有良好的强度和韧性。金相分析显示调质后的显微组织主要由回火索氏体组成,结构稳定。In this paper,the effects of different quenched-tempered heat treatment processes on the microstructure and mechanical properties of 30CrMoA round steel for sucker rod are studied.The strength and toughness of the material are improved by adjusting the quenching and tempering temperatures as well as optimizing heat treatment process aiming at the actual application requirements of 30CrMoA steel.The experimental results showed that the yield strength,tensile strength,yield ratio and impact energy of the material could be significantly improved with proper quenching and tempering,especially under the conditions of 850℃quenching(water cooling)+540℃tempering(water cooling),the comprehensive mechanical properties of round steel 30CrMoA for sucker rod were the best,which was with good strength and toughness.The metallographic analysis showed that the quenched and tempered microstructure was mainly composed of tempered sorbite,which was with stable microstructure.
