摘要
介绍了80t氧气顶底复吹转炉经LF、VD处理后连铸出Φ210mm及Φ270mm圆坯,经Accu-Roll轧机生产Φ194mm×16mm和Φ273mm×20mm接箍料无缝钢管,通过精准的连铸坯成分控制和控轧控冷工艺。
The paper details that Ф210mm and Ф270mm casting round billet was produced by 80t BOF and LF and VD treatment, and that the Accu - Roll mill production Ф194mm × 16mm and Ф273mm ×20mm seamless steel pipe coupling material is discussed, by precise composition control and controlled rolling and cooling process, so that hot rolled steel performance fully meets the requirements of API SPEC 5CT Specification
