摘要
根据客户要求,青岛特钢采用LD(100t)转炉→LF(100t)精炼炉→RH(100t)真空脱气→CC连铸→轧制工艺首次生产了N80级石油套管用非调质钢36Mn2V管坯。产品实物质量检测结果表明,所生产的36Mn2V钢化学成分、晶粒度、夹杂物、低倍组织、表面硬度等指标均符合客户要求,同时氧氮氢含量较低,表面质量较好,用户使用效果良好。
According to customer requirements, non-quenched and tempered steel 36Mn2V billet of N80 grade oil casing was produced for the first time by LD (100t) converter / LF (100t) refining furnace / RH (100t) vacuum degassing / CC continuous casting and rolling process. The results of product quality test show that the chemical composition, grain size, inclusions, macrostructure and surface hardness of 36Mn2V steel meet the requirements of customers. At the same time, the content of oxygen, nitrogen and hydrogen is low, the surface quality is good, and the application effect for users is good.
