摘　　要：热顶锻性能是抽油杆圆钢综合质量的一个重要指标。利用铸坯低倍组织及金相分析对抽油杆圆钢热顶锻裂纹产生的原因进行了分析,结果表明,在生产过程中形成的表面擦划伤和靠近表面的大型夹杂物是导致圆钢在热顶锻试验中表面开裂的主要原因。Hot forging performance is an important parameter to measure sucker rod steel quality. By analyzing casting billet organization structure and sucker steel metallographic after hot forging process, we find that the cause of surface cracking formed in the hot forging process is relative to scratch on the steel surface and the large non metallic inclusions in the steel.
