摘要为了提高国内油井管钢质量,采用扫描电镜对比了日本和国内油井管钢中夹杂物成分和形貌,统计了夹杂物尺寸分布、夹杂物间距和夹杂物分布等参数,基于FactSage热力学软件平衡凝固模型分析了冷却过程中夹杂物的演变过程,基于夹杂物碰撞数量平衡模型,讨论了油井管钢中夹杂物碰撞率。结果表明,日本油井管钢中夹杂物主要为CaS包裹的镁铝尖晶石,国内油井管钢中夹杂物主要为钙铝酸盐包裹的镁铝尖晶石夹杂物和纯镁铝尖晶石夹杂物。日本油井管钢夹杂物比国内油井管钢夹杂物数量少、尺寸小、分布更均匀。日本油井管钢中夹杂物数量密度达到7.5个/mm²,国内油井管钢中夹杂物数量密度达到28.3个/mm²。日本油井管钢中夹杂物最大尺寸不超过5 μm,国内油井管钢中夹杂物最大尺寸达到20 μm。FactSage计算冷却过程中夹杂物演变结果与试验结果吻合。国内油井管钢中夹杂物碰撞率比日本油井管钢中夹杂物的碰撞率高2个数量级。

Abstract：In order to improve the performance of OCTG (oil country tubular goods) steel, the composition and morphology of inclusion were observed by scanning electron microscope. The particle size distribution, inter-surface distance, and distribution of inclusions were analyzed. The evolution of inclusions during the cooling process was analyzed based on the equilibrium solidification model with FactSage software. The collision rate of inclusions in OCTG steel was estimated based on the inclusion collision number balance model. The results indicate that there were mainly CaS with encapsulated Spinel inclusions in Japanese OCTG steel, and CaO with encapsulated Spinel and pure Spinel inclusions in Chinese OCTG steel, respectively. In comparison with the inclusions in Chinese OCTG steel, the inclusions in Japanese OCTG steel are less and smaller and distribute more uniformly. The number density of inclusions is 7.5/mm² in Japanese OCTG steel and 28.3/mm² in Chinese OCTG steel. The largest inclusions are less than 5 μm in Japanese OCTG steel, which reaches 20 μm in Chinese OCTG steel. The calculated results about inclusion evolution during the cooling process based on FactSage are in good agreement with experimental results. The collision rate of inclusions in Chinese OCTG steel is two orders of magnitude higher than that in Japanese OCTG steel.
