摘要
随着石油工业的不断发展,海底油气开发已经逐渐从浅海大陆架延伸至深海域,在降低成本的基础上,保证厚规格钢板的高强度高韧性以及抗层状撕裂性能是未来海洋平台用钢的发展方向。本文介绍了国内外高强度海洋平台用钢的研究现状,分析了此类钢板生产亟需解决的关键技术难题,阐述了东北大学轧制技术及连轧自动化国家重点实验室(RAL)近年来在高强度厚规格海洋平台用钢研究领域的工作以及工程应用情况。
With the development of petroleum industry in China,undersea oil and gas devel-opment has gradually extended from shallow of the continental shelf to deep waters,therefore, high strength and high toughness and excellent resistance to lamellar tearing are the properties which heavy-gauge offshore platform steel must have in the future. This paper presents the re-search progress on high performance offshore platform steel at home and abroad in recent years,and the key technical problems of such steel production also be mentioned. Research work and engineering applications of high-strength plates in The State Key Laboratory of Rolling and Automation,such as Ultra Fast Cooling（UFC）andγ＋αquenching technique,are finally reviewed.
