摘　　要：采用C-Mn-Nb-Ti微合金化成分设计、低P、低S高纯净度铸坯冶炼以及合理的控轧控冷工艺,充分发挥细晶强化和析出强化作用,在内蒙古包钢稀土钢板材有限责任公司2 250mm生产线上成功试制了J55石油套管用热轧带钢,用该热轧带钢制成的ERW焊管具有高强度、高韧性、抗粘扣的良好力学性能,且探伤合格率不小于99%。The hot rolled strip for ERW welded J55 oil pipe was developed in 2 250 mm production line of Rare Earth Steel Plate Co. , Ltd. of Baotou Steel. With the chemical composition of C-Mn-Nl-Ti microalloyed design, the pure slab smelting of low P and S was obtainecl. By reasonable controlled rolling and controlled cooling process, the strengthening role of fine-grain and precipitation was realized. The ERW welded pipe had high strength, high toughness, excellent anti-galling property, and more than 99 % qualified ratio.
